Very informative, Dr Ankit. Can you do a similar video on microwave ovens? Some believe that microwave can cause cancer. I'd like to know if research bears this out. Thanks.
Thank you for the question! Just like infrared, microwaves are also classified as non-ionizing radiation. In fact, the energy of microwaves is lower than infrared and visible light (i.e. microwaves have lower frequency than both visible and infrared light). When absorbed, the main effect of microwaves is that it causes vibration in molecules. This leads to friction and therefore the production of heat - a property that we use to heat up our food! Non-ionizing radiation like microwaves, infrared and visible light, cannot cause cancer. Research also shows that there is no detrimental health issues associated with microwaved food. Also, you may find the following resources helpful if you would like to read further: www.arpansa.gov.au/understanding-radiation/radiation-sources/more-radiation-sources/microwave-ovens www.icnirp.org/en/frequencies/high-frequency/index.html
Yup that's right Mike. Here's a direct quote from the World Health Organization on this point: "The design of microwave ovens ensures that the microwaves are contained within the oven and can only be present when the oven is switched on and the door is shut. Leakage around and through the glass door is limited by design to a level well below that recommended by international standards." www.who.int/peh-emf/publications/facts/info_microwaves/en/
Thank you TechKerala, I'm glad you found the video helpful! The response to this video has been fantastic and I am very grateful for everyone's encouragement :D
Years later in the future when we're all in our 60s or 70s there will be commercials on TV saying "have you or anyone you know used a phone that emits infrared light? Then you may be entitled to financial compensation!"
Thank you very much for the clear explanation of how infrared radiation can possible affect the eyes by using the Face ID. After watching your video, I turned off immediately the Face ID that i use to unlock my iphone and some few apps. Since then, i feel better. No more temporal headache, eye strain and the blurry vision that i am experiencing after buying my new iphone now slowly disappearing. Same experience with my friend who uses Samsung.
Those 15(and counting) dislikes are the ones who don't know anything about physics and biology.Where's this channel been from my life.what a quality and awesome content.very well explained. You deserve millions of subscribers.keep up the good work.eagerly waiting for your next video.
“There are no known effects” doesn’t mean there aren’t any . May be we will know them after 10 years. I understand physics behind it , most likely it is ok. But we don’t have data yet .
From personal use of the iris scanner when i first for my s8, it caused mild headaches over time. Ifter turning it off i no longer had them. So i believe there has to be something more to it than the potential heating up skin and such
I blocked all the apple front sensors and only use passcodes - blocking the sensors (including the dot projector) eliminated the headaches I was getting from using the iPhone X - At one stage the tape came off the dot projector and my headaches and eye strain returned - blocked them and issues solved
Wonderful video and so well presented. Loved it. Can I ask you two things. 1. What about the new LiDAR in iphone 12 pro - they say iphone uses that for face recognition and you can use it to take selfies - but isn't LASER even more dangerous that Infra-red? But surely, apple would not have released it if there were concerns that usually go with Laser - burn spots on the retina. 2. I'm a doc too. Love the way you developed a video to explain how cataracts happen with Infra-red. It was amazing. I'd like to do something myself for my patients. Are you able to share how you developed that video. It looks like a specific video made for you rather than a stock video. I'd love to do something too. Are you able to help? And of course, thanks
I used to think I felt a bit of prickly heat when using Samsung’s iris scanner. It could’ve been my imagination but I am generally pretty sensitive to small changes
I've upgraded to the iPhone 14 pro from a s22 ultra that uses a finger print. immediately the same week my eyes felt weird. it felt like I was loosing my vision. I turned Face ID off and after a week my eyes went back to normal. I personally am a bit sensitive to light, maybe that's why I experience this but it felt horrible. apple needs to integrate the fingerprint
The bad thing is that the flood illuminator (iPhone) flashes when you work with your phone, not only at unlocking. You can see this through another phone camera.
I used to feel red eyes, headache and dizziness with S9+ Iris scanner. I thought this was due to COVID-19 however, the condition persisted even after several weeks after recovery. So I just guessed this could be due to Iris Scanner and disabled it. The symptoms disappeared after 1.5 days. Splashing cold water on closed eyes also helps. I used to unlock around 50 times per day with about 2 to 4 seconds of exposure everytime, which is not good in the long run.After several years I am sure there will be several reported cases.
I got an iPhone 11 a few days ago and the first 2 days I experienced headaches and disorientation it was really bad (I have astigmatism and my eyes are sensitive) so I covered the projector and IR camera and a day later my symptoms went away slowly. I’m 99% sure this was caused by the face ID technology. Guys you must cover it it aluminum foil tape because it’s the inly thing that block Infrared light
Same with me. After using Iphone X for 1 month I got eye strain, eye pain and headeach. Is it work when you cover it with alumunium foil? Im so sad knowing this truth, I think to sell this phone now..😢😢
I turned on the system called "Smart Keep Bright" for like a couple months and its always scan my eyes to keep the screen on. Does it really matter for my eye health?
Hi Tracey, this is a great question! The disclaimer for Samsung Iris Scan says "Anyone who experiences dizziness, seizures, loss of awareness, blackouts, or other symptoms related to an epileptic condition, should see a doctor before using iris recognition". Photosensitive epilepsy is generally associated with visible light rather than infrared. In an article, red-blue flashes from the Pokeman cartoon were reported to trigger seizure like events in 685 children (www.ncbi.nlm.nih.gov/pubmed?term=16146439). I haven't seen any reports of infrared causing seizures. I think that's because visible light triggers the occipital lobe of the brain (the part that processes vision), but infrared is invisible to us, so it doesn't activate the brain. Having said that, if I had photosensitive epilepsy, I would take the conservative approach and not use Face ID. The convenience just wouldn't be worth the risk of having a seizure (even if that risk is very small)! This is a great question and would be worth asking your Neurologist. He/She will be able to guide you more specifically about your situation. In the meantime, this is a good resource if you are looking for more information about photosensitive epilepsy: www.epilepsy.com/learn/triggers-seizures/photosensitivity-and-seizures
All over the world trucking companies are installing so-called "Driver Fatigue Monitoring Systems" which uses 850 nanometers wavelength. With IR light source positioned 40cm away from your face, at a rate 8-12 hours a day.. there will be a lot of blind truck drivers in the next few years..
Excellent video ! Hopefully more phones and the iPhones will offer under screen fingerprint sensor as an option to use instead. The Touch ID on iPhones is just so fast and easy to use for example
Glad you enjoyed the video Mike! Samsung has taken the game to another level with their under screen Ultrasonic fingerprint sensor on the S10/S10+. I'm sure Apple is working on a way to respond in their 2019 line up of iPhones.
It might be possible that the guy's (Baintek at 5:20) phone's flood illuminator was damaged so it didn't stop working when FaceID was turned off, and this might be the reason he was facing discomfort.
Very good explained and great video! I subscribed to your channel for more awesome and productive videos in the future. I bought the iPhone XS since a few days and am using FaceID with no noticeable issues yet.
I'm glad you found the video useful and thank you for taking the time to post a comment! It always makes me happy to hear from people that have learned something new from my videos :D
I was having problems with my vision the last months, since I turned of FaceID they stopped. Im not saying that FaceID could be completely responsible for eyes problem but I think it have something related.
Thank you very much for this video! Do you know, if I will not set up/install FaceID, can I be sure, that the infrared dots will not be used by apple for anything else/other functions I don`t know?
Hi! Thanks a lot. Very informative video. Can you pls tell me about the infrared light from the cctv cameras? My son keeps staring at the cctv camera, baby monitor at my home. Sometimes he puts his face really close. Pls tell me if it is safe? Thank you.
Thank you for your infos, very useful..... My question is: is a camera wich sends infrared emissions to your face and eyes for a twelve hour shift to monitore if your eyes close then sends you vibrations so you don't fall asleep while driving your truck can be harmfull to your eyes ? Would you know wich study to read about the subject (specific to twelve hour exposure) ? Thank you very much for your time !
Hi Jimi, great question! The health effects of infrared ultimately depends on the amount of exposure to the eye (more formally known as the radiance dose). There are a number of factors that influences radiance dose, and one of them is time. The longer the duration of exposure, the more dose your eye will receive. So if you have an infrared device monitoring your eye for 12 hours, then your eye will receive more dose than if you only wore that device for 10 minutes. However, if the dose of infrared from such a device is still below the international exposure limits, then it should be safe to use. I have two suggestions for you if you want to investigate further: 1) You may wish to read the full guidelines on limits of infrared exposure here: www.icnirp.org/en/frequencies/infrared/index.html The guidelines are quite technical but provide a very comprehensive overview of the health effects of infrared including how radiance dose is calculated and the exposure limits. 2) You may wish to contact the manufacturer of the monitoring device and ask them whether the device has been certified against international standards Hope this helps! Let me know if you have any further questions :)
Yes buddy. I'm a truck driver and exposed to this shit 10 hours a day. We use "Seeing Machines" Guardian device, which uses 850nm and 940nm frequency. I obtained enough info for a massive lawsuit already. There is simply no way around it, at that rate of exposure its impossible to make it harmless...
Now it's the end of the year 2018, I'm holding the new iPhone xr with a LCD Display, no pwm issues, but I'm pretty sure about the eye strain that I have, feels like burning, and the back of my brain, and I think it's because of the Face ID, cause I tried cover it, and it feels better.
If you do feel something, you can try turning off Face ID and see if that helps. Also, the Animoji feature uses the infrared TrueDepth camera system too. You may want to try turning that off as well.
DocUnlock Thanks for the suggestion, I've tried that before, but it's too complicated to type the code everytime, so I have to turn it on. Plus I'm not sure that's the only reason, the screen is not as great as apple claimed, the color, the night shift is not as natural as some android phone, it's too yellow, and I have to "reduce white point" to relax my eyes, I don't know, maybe it's too "liquid " to me... Anyways, thanks for replying, I think I'll just sell it as a second handed and leave it at that
DocUnlock And may be the low resolution, I forgot to say, there's a vote on a forum I saw about the iPhone xr caused eye strain problem, but that's another story
I turned off faceID. Extreme exposure also means long term. Read that again. Extreme exposure also equals long term. What will happen in 20 ..30 years ??
Is this the same technology being used in new car dashboards to read whether the driver's eyes are open and alert if you may be falling asleep? Is this safe on the eyes as it's continuously scanning your face during the entire driving session?
The Problem is that Face ID is ALWAYS ON. You can easily check it with another Phones Camera (because humans cant see it), also when Face ID is turned off and while browsing the Apps the Beam still lits every 5 seconds. This is scary and questionable, also its on when the screen is off ! Apple devices are DEFINATELY DAMAGING THE EYES
Did you know your remote for your tv or other things also can be seen on camera too? Are you scared of that? Put your camera against the front of your remote and push your remote button you’re gonna see a red light in the camera. Did you ever go to school?
Amount of exposure: If apple is going to use face-id in ALL its products from here on out, including its iMacs and Macbooks which is coming., then I do believe your will be getting TONS of exposure daily. How many times do you look at your phone per day? It also illuminates while you are using the phone just to check it's you. You are going to use these Apple FaceID products for the next 10 years non stop every day and not worry about the 'amount of exposure'? Anyone that does that is a braver man than me.
Every time I try to set it up I start getting a small sharp pain like deep in my head and it sorta turns into a headache. So like the thing about some people being oversensitive to infrared, that would just be my luck so I’m not even surprised, I just use a passcode it keeps me from using my phone too much anyway :/
Hi Brendan, in situations like your own, it is always tricky to pin down the exact cause of eye strain. The approach here would be a process of elimination - trying to address each possible cause one by one and see which one makes a difference. You've already turned off Face ID which is a good start. Here are some other things you can do if turning off Face ID doesn't help: 1. Turn off Animoji feature - the Animoji feature also uses the infrared system to detect your face 2. Turn down screen brightness - high brightness may cause your eyes to squint (even without you being conscious of it. This can lead to eye strain. 3. Try using a blue light filter - reducing blue light from screens can reduce eye strain for some people. I think iOS 9.3 onwards has a built in blue light filter called 'Night Shift'. You can try turning this feature on all the time (ie not just for night time use). It would be great if you let us know what happens. It can help other people who may also be experiencing the same problem :)
As long as the iPhone X suits your needs, then I think it is fine to purchase one. You always have the option of turning off Face ID if you don't want it. Personally I'm more of an Android user, so I haven't used an iPhone in a long time!
Thnx a lot for the information, but unfortunately, you can't switch off Iphone IR scanner, it continues to work even after disabling face ID function...(I tested it with video camera)
iPhone X after 3 days of using the X I had watery eyes eye aches almost sinus like - I thought it may have been an infection or hay fever - I took eye drops regularly I turned off all the face unlock pretty much turned off everything but after 12 months the issues persisted - I took some high speed video and the sensors including the flood illuminator still operate - about a month ago I’ve covered over all of the sensors except the front camera and after 3 days my eye issues had improved by about 70% - it’s now about 1 month and my eyes have improved about 90% but still get watery eyes which I think is due to the OLED flicker - make sure you don’t let the screen dim - I think Apple could well have a class action against them with these dangerous phones
I was looking how iris scanner works on Samsung Note 9.. Luckily it brought me to your channel, I immediately subs to your channel.. Hopefully you can share more good contents like this.
There are rumours that Samsung flagships in 2019 may not include iris scanning - we'll have to wait and see if this is true. On the other hand, it is predicted that the 2019 iPhone line up will have upgraded Face ID features: 9to5mac.com/2018/11/01/upgraded-face-id-coming-to-2019-iphones-new-ipads-to-arrive-late-next-year-or-early-2020-says-kuo/ Either way, it will be interesting to see what happens :)
Turning off face id on an iPhone does not work because the ir light is always active even after keeping it on a disabled mode. Same on phones with iris scanner. I see no point of harming my eyes with these tech.
Mashriq Afroze Alam iPhone X after 3 days of using the X I had watery eyes eye aches almost sinus like - I thought it may have been an infection or hay fever - I took eye drops regularly I turned off all the face unlock pretty much turned off everything but after 12 months the issues persisted - I took some high speed video and the sensors including the flood illuminator still operate - about a month ago I’ve covered over all of the sensors except the front camera and after 3 days my eye issues had improved by about 70% - it’s now about 1 month and my eyes have improved about 90% but still get watery eyes which I think is due to the OLED flicker - make sure you don’t let the screen dim - I think Apple could well have a class action against them with these dangerous phones
@@BarryMaskell The oled flicker does not strain my eyes. My eyes only strain due to the ir light & the dot projector which is always on, on all iPhone x series and the new iPads. If I cover the sensors what's the point of using an iPhone. In that case Androids look like Samsung & Oneplus is way better now none have iris scanner or any sensors to harm consumers eye😊😊♥️. Most Android phones have fingerprint lock-screen without harmful sensors.
Hi Brock, those phones would also be subject to the infrared safety standards that apply to Samsung and Apple. So in theory they would be safe too although I haven't looked up the specifications myself. You may wish to check whether those phones have been certified against international standards.
As an example, the LG G3 uses an infrared laser autofocus system (www.anandtech.com/show/8062/a-closer-look-at-the-g3s-ir-laser-auto-focus-system). This should be safe for your eyes as long as the manufacturer keeps the infrared exposure below the safety limits.
Question do you think faceID is safe? You said it’s a minimal amount as far as hell but what if I’m on locking my phone 20 times by my official recognition and I’ve got cooking and I’m on the computer laptop and then I’m also getting in for red from other computers around me other people‘s phones their face ID being being around📡📲📡📲 Hacking or will my phone/ iPhone/ Apple take my images and use against me down the time line?!!
Fahd Boufoul It’s safe but soon our future will have Face ID or Body id to unlock every technology in our lives that’s why we should get out more and put our technology off sometimes and I live in modern house so idk what to do 😂
Hi Azad, twitching of the eye is very common and can be related to eye strain. The medical name is blepharospasm - 'blepharo' refers to the eyelid and 'spasm' refers to the spasm of the muscle that controls the eyelid. Some other reasons for blepharospasm include lack of sleep and irritation due to pollution. Usually blepharospasm doesn't indicate any serious problem and should go away with rest. Here is an article if you're interested in reading further: www.mayoclinic.org/symptoms/eye-twitching/basics/causes/sym-20050838
Okay if IR is bad for eyes then, both face ID and IRis scanner should not be used. Buy an iphone with touch Id and a samsung phone with fingerprint sensor
before face id was kinect by Microsoft with same dot projector technology like apple "invented" years after and was no problem with eyes and that was longer exposure
Recently, infrared temperature devices are being used to supposedly combat the “dangerous🙄” Corona virus spread ( I say supposedly because I think there’s a psychological reason).... Do you think, know or have any opinion on it affecting the pineal gland? Thank you for the great videos!

There are a number of factors that influences radiance dose, and one of them is time. The longer the duration of exposure, the more dose your eye will receive. So if you have an infrared device monitoring your eye for 12 hours, then your eye will receive more dose than if you only wore that device for 10 minutes. However, if the dose of infrared from such a device is still below the international exposure limits, then it should be safe to use.
I have two suggestions for you if you want to investigate further:
1) You may wish to read the full guidelines on limits of infrared exposure here: www.icnirp.org/en/frequencies/infrared/index.html
The guidelines are quite technical but provide a very comprehensive overview of the health effects of infrared including how radiance dose is calculated and the exposure limits.
2) You may wish to contact the manufacturer of the monitoring device and ask them whether the device has been certified against international standards
Hope this helps! Let me know if you have any further questions :)
I really appreciate your insight and suggestions I will do the research, thank you very much !@@DocUnlock
Yes buddy. I'm a truck driver and exposed to this shit 10 hours a day. We use "Seeing Machines" Guardian device, which uses 850nm and 940nm frequency. I obtained enough info for a massive lawsuit already. There is simply no way around it, at that rate of exposure its impossible to make it harmless...
You're a legend doc, thanks.
Now it's the end of the year 2018, I'm holding the new iPhone xr with a LCD Display, no pwm issues, but I'm pretty sure about the eye strain that I have, feels like burning, and the back of my brain, and I think it's because of the Face ID, cause I tried cover it, and it feels better.
If you do feel something, you can try turning off Face ID and see if that helps. Also, the Animoji feature uses the infrared TrueDepth camera system too. You may want to try turning that off as well.
DocUnlock Thanks for the suggestion, I've tried that before, but it's too complicated to type the code everytime, so I have to turn it on. Plus I'm not sure that's the only reason, the screen is not as great as apple claimed, the color, the night shift is not as natural as some android phone, it's too yellow, and I have to "reduce white point" to relax my eyes, I don't know, maybe it's too "liquid " to me... Anyways, thanks for replying, I think I'll just sell it as a second handed and leave it at that
DocUnlock And may be the low resolution, I forgot to say, there's a vote on a forum I saw about the iPhone xr caused eye strain problem, but that's another story
Seems like the display just doesn't quite suit you. Thanks for sharing your experience
@@DocUnlock Thanks for making this video, I hope one day the big companies could aim something more than just benefits.
I turned off faceID. Extreme exposure also means long term. Read that again. Extreme exposure also equals long term. What will happen in 20 ..30 years ??
Nothing since it’s too insignificant
With that logic you won’t be able to step outside the house
@@anarchistmaverick9507 don’t step outside ur house without a major reason
News channels be like 4:36 to 4:39.
Great video. Nice production, under 100 subs lmao this channel is gonna blow up.
Glad you enjoyed the video and I really appreciate your encouragement. Thanks mate!
Dr. Ankit, is the smart camera's night vision IR LED, which emits invisible light, harmful to our eyes? I have one in my bedroom
Is this the same technology being used in new car dashboards to read whether the driver's eyes are open and alert if you may be falling asleep? Is this safe on the eyes as it's continuously scanning your face during the entire driving session?
it's not and to the nervous system
Wow
Well done Ankit
And thanks to Samsung even if i disable iris scanning i have fingerprints sensor
Can I use IR sensor to detect eye blink ?
The Problem is that Face ID is ALWAYS ON.
You can easily check it with another Phones Camera (because humans cant see it), also when Face ID is turned off and while browsing the Apps the Beam still lits every 5 seconds. This is scary and questionable, also its on when the screen is off !
Apple devices are DEFINATELY DAMAGING THE EYES
Did you know your remote for your tv or other things also can be seen on camera too? Are you scared of that? Put your camera against the front of your remote and push your remote button you’re gonna see a red light in the camera. Did you ever go to school?
how about the health effects on bluetooth close to our brain for long periods of time as with wireless ear plugs?
I haven't looked into this. I'll add it to my list of potential future topics
Amount of exposure: If apple is going to use face-id in ALL its products from here on out, including its iMacs and Macbooks which is coming., then I do believe your will be getting TONS of exposure daily. How many times do you look at your phone per day? It also illuminates while you are using the phone just to check it's you. You are going to use these Apple FaceID products for the next 10 years non stop every day and not worry about the 'amount of exposure'? Anyone that does that is a braver man than me.
Every time I try to set it up I start getting a small sharp pain like deep in my head and it sorta turns into a headache. So like the thing about some people being oversensitive to infrared, that would just be my luck so I’m not even surprised, I just use a passcode it keeps me from using my phone too much anyway :/
So using my iPhone Face ID everyday won’t harm me in the long run?
So I just bought an iPhone XR a few days ago, and I’ve felt a little bit of a pain in my eyes, what’s the best option here?
I turned off Face ID for now will that make a difference?
Hi Brendan, in situations like your own, it is always tricky to pin down the exact cause of eye strain. The approach here would be a process of elimination - trying to address each possible cause one by one and see which one makes a difference.
You've already turned off Face ID which is a good start. Here are some other things you can do if turning off Face ID doesn't help:
1. Turn off Animoji feature - the Animoji feature also uses the infrared system to detect your face
2. Turn down screen brightness - high brightness may cause your eyes to squint (even without you being conscious of it. This can lead to eye strain.
3. Try using a blue light filter - reducing blue light from screens can reduce eye strain for some people. I think iOS 9.3 onwards has a built in blue light filter called 'Night Shift'. You can try turning this feature on all the time (ie not just for night time use).
It would be great if you let us know what happens. It can help other people who may also be experiencing the same problem :)
Long story short no unless the infrared is overly extreme
What about the new LiDAR scanners on apples new divices like iPhone 12 Pro / iPad Pro?
Actually it was MICROSOFT on it's LUMIA 950 models that used it first...!!! Don't promote the others two only, as always !!!
Yea true that.
Nice video btw :) would you still recommend purchasing an iPhone x or stick with a older model
As long as the iPhone X suits your needs, then I think it is fine to purchase one. You always have the option of turning off Face ID if you don't want it. Personally I'm more of an Android user, so I haven't used an iPhone in a long time!
@@DocUnlock same I currently have a Samsung s6 but looking to upgrade to the iPhone x
Wonder if they share the data of irris scanning and face recognition to goverment and police
Infared overlaps with microwaves at the 1mm range
Which is better for eye comfort lcd or amoled??
Ever found out? Lol
Keep it up bro.....your channel will definitely grow in future if you will keep on making videos like this. 👍
Thanks so much! Hope you're having a great Christmas and New Year break
Can i ask something? I have an iPhone 11 and i was wondering: what is too much on your phone without a break?
Thnx a lot for the information, but unfortunately, you can't switch off Iphone IR scanner, it continues to work even after disabling face ID function...(I tested it with video camera)
iPhone X after 3 days of using the X I had watery eyes eye aches almost sinus like - I thought it may have been an infection or hay fever - I took eye drops regularly I turned off all the face unlock pretty much turned off everything but after 12 months the issues persisted - I took some high speed video and the sensors including the flood illuminator still operate - about a month ago I’ve covered over all of the sensors except the front camera and after 3 days my eye issues had improved by about 70% - it’s now about 1 month and my eyes have improved about 90% but still get watery eyes which I think is due to the OLED flicker - make sure you don’t let the screen dim - I think Apple could well have a class action against them with these dangerous phones
You should get an lcd screen then... (iPhone Xr) or the Xs but that phone also has flickering problems...
Kleropunt YEET No just cover over all the sensors fixed the problem
@@BarryMaskell even I have the same issue. what tape u used. I tried many tapes but didn't work help plz.....
How do u or what type of thing u use to cover the face id ?
I always thought it was funny how my phone wouldn't know who I was when I took mushrooms.
Nice explanation I subscribed, you deserve more subscribers the videos that you make are amazing
Thanks for the encouragement Jakob!
So he receives payments from Samsung and Apple then.
I was looking how iris scanner works on Samsung Note 9..
Luckily it brought me to your channel, I immediately subs to your channel..
Hopefully you can share more good contents like this.
I'm glad this video was useful for you :)
Anyway last Samsung's phones has even Fingerprint sensor that have been removed on the last Iphones.
There are rumours that Samsung flagships in 2019 may not include iris scanning - we'll have to wait and see if this is true. On the other hand, it is predicted that the 2019 iPhone line up will have upgraded Face ID features:
9to5mac.com/2018/11/01/upgraded-face-id-coming-to-2019-iphones-new-ipads-to-arrive-late-next-year-or-early-2020-says-kuo/
Either way, it will be interesting to see what happens :)
Turning off face id on an iPhone does not work because the ir light is always active even after keeping it on a disabled mode. Same on phones with iris scanner. I see no point of harming my eyes with these tech.

Mashriq Afroze Alam iPhone X after 3 days of using the X I had watery eyes eye aches almost sinus like - I thought it may have been an infection or hay fever - I took eye drops regularly I turned off all the face unlock pretty much turned off everything but after 12 months the issues persisted - I took some high speed video and the sensors including the flood illuminator still operate - about a month ago I’ve covered over all of the sensors except the front camera and after 3 days my eye issues had improved by about 70% - it’s now about 1 month and my eyes have improved about 90% but still get watery eyes which I think is due to the OLED flicker - make sure you don’t let the screen dim - I think Apple could well have a class action against them with these dangerous phones
@@BarryMaskell it is because my eye power is -4.5 on both my eyes.
@@BarryMaskell The oled flicker does not strain my eyes. My eyes only strain due to the ir light & the dot projector which is always on, on all iPhone x series and the new iPads. If I cover the sensors what's the point of using an iPhone. In that case Androids look like Samsung & Oneplus is way better now none have iris scanner or any sensors to harm consumers eye😊😊♥️. Most Android phones have fingerprint lock-screen without harmful sensors.
@@BarryMaskell I am using a xperia phone now after trying iPhone x, planning to switch to oneplus soon.
Are Infrared Phone Unlock given in Phones like Vivo v11 Pro and Poco f1, harmful for eyes?
Hi Brock, those phones would also be subject to the infrared safety standards that apply to Samsung and Apple. So in theory they would be safe too although I haven't looked up the specifications myself. You may wish to check whether those phones have been certified against international standards.
@@DocUnlock one more question sir...are the laser-focus given in camera of some smartphones, harmful for our eyes?
As an example, the LG G3 uses an infrared laser autofocus system (www.anandtech.com/show/8062/a-closer-look-at-the-g3s-ir-laser-auto-focus-system). This should be safe for your eyes as long as the manufacturer keeps the infrared exposure below the safety limits.
thank for reading that for us...I almost fell asleep just reading the title
Question do you think faceID is safe? You said it’s a minimal amount as far as hell but what if I’m on locking my phone 20 times by my official recognition and I’ve got cooking and I’m on the computer laptop and then I’m also getting in for red from other computers around me other people‘s phones their face ID being being around📡📲📡📲
Hacking or will my phone/ iPhone/ Apple take my images and use against me down the time line?!!
Which software you use for animation?
Soooo, is it safe or not????
Fahd Boufoul It’s safe but soon our future will have Face ID or Body id to unlock every technology in our lives that’s why we should get out more and put our technology off sometimes and I live in modern house so idk what to do 😂
Wonderful video, thank you.
when i stare at the screen and the phone my right eye is flickering any particular reason for it?
Hi Azad, twitching of the eye is very common and can be related to eye strain. The medical name is blepharospasm - 'blepharo' refers to the eyelid and 'spasm' refers to the spasm of the muscle that controls the eyelid. Some other reasons for blepharospasm include lack of sleep and irritation due to pollution. Usually blepharospasm doesn't indicate any serious problem and should go away with rest.
Here is an article if you're interested in reading further: www.mayoclinic.org/symptoms/eye-twitching/basics/causes/sym-20050838
Ok, but what about the warning when you got from Samsung? at 0:27
I would be hesitant to use this technology every day, several times per day, for years.
subscribed! u deserve more than 2k subs!!
Thank you for your support! I'm glad you're enjoying my work :)
Watching this with an iPhone 6 and feeling unrelated because I am too broke 🤣
Dr. I can't understand English good..now the infrared is hurting us ??
Pls answer me 😘
Very impressive way of explaining
Thank you Sanjay :)
Only if you're really young
If the iris scanner has no harm to the eye, why Samsung remove it from s10 ?
Maybe to get that Infinity-O display. Plus they introduced the ultrasonic fingerprint scanner.
Thank you sir, a very good video.
Okay if IR is bad for eyes then, both face ID and IRis scanner should not be used. Buy an iphone with touch Id and a samsung phone with fingerprint sensor
Great video and well made thank you
best way to explain, great job
before face id was kinect by Microsoft with same dot projector technology like apple "invented" years after and was no problem with eyes and that was longer exposure
Recently, infrared temperature devices are being used to supposedly combat the “dangerous🙄” Corona virus spread ( I say supposedly because I think there’s a psychological reason).... Do you think, know or have any opinion on it affecting the pineal gland? Thank you for the great videos!
You should have a TV show, I'd watch daily
