- The most intricate part of any Smart Glasses is their lenses. Have you ever wondered how they get the display to appear out in space?
Learn a little about how the properties of light effect what is and isn't possible with this new technology. Only a couple more years until they replace our cellphones so you might as well learn about how they work now.
Sorry this is so long, but there really is no easier way to explain some things. Hope you stick through it until the end and learn a little about how the lenses work in smartglasses. Thanks for watching and if you like what you see please consider subscribing.

Ah so you don't know how they work then. It's OK just to say that rather than try to wing it.
wtf are you yapping about? He obviously does know what he’s talking about. You need to watch the whole video my man😭
@@y-it4207 Clearly you don't.
@@Drenov did you think of that one all on your own?🤣
Hey Andy, nice of you to take the time to describe this! It was a previous video of yours ... "I've seen the future"(?) where you interviewed PT that convinced me to buy more Vuzix. I think that was before Cathy of ARK began investing in them I believe, which caused me to buy more as well! 🤔🙃😎
Thanks Andy. Interesting stuff. You answered a few things I had wondered about. Nice job explaining a topic that is challenging to explain. Love this tech. These certainly are game changers. Next Gen can’t get here soon enough. Please keep the Vuzix info coming. Bought the upgraded Blades and was very impressed. The support and customer service I experienced at Vuzix was excellent. You are quite lucky to have been able to visit Paul and the facility.
Thanks for the feedback. Wasn't going to do this one because I didn't know if anyone cared. Glad I did. Paul is great, I'm happy for their success. Can't wait for the next gen also.
how do they engrave the gratings ? like lasers?
nice video! as you said two years ago, now glasses have those grating structures in front of both eyes. just to add a bit of more info, the input grating collects light from the projector and sends it to the fold grating. in this path light travels inside of the glass like in an optical fibre. then the fold grating redirects the light to the outcoupler grating, this also happens inside of the glass. only when the light reaches the outcoupler the light bounces straight out of the glass into the eyeball. the cool thing about this grating-based device is that the glass or waveguide can be very thin and light weight, contrary to mirror-based XR devices such as google glass. and gratings are super tiny structures that the waveguide looks transparent.
Thanks for doing this. Brilliant explanation. Can’t believe how buried this video is in an ocean of fluff.
Glad it was helpful!
Andy… you have done an amazing job explaining this concept. i have been scratching my head on the exact question that how do they give that feeling of depth and it feels like the object is out there and not right on your display. Watched so many videos.. with even super tech people explaining it.. but could only understand now because of your simplistic way to explain things. Big thanks 🙏
That’s great to hear. Whenever someone explains something to me and then it makes sense , I like to turn around and try to tell it in a way other people will get it. Great to hear it worked!
(explained by a proper mRoon)
Came to this video because I'm getting the rayneo X2s.
Prescription lenses snap in. Super excited
Have fun!
so... it's a projection in to the lens and not in to the eyes.
great. really thank you for the explanation.
I was really worried about this tech.
The usual screens throw light into your eyes. Too much time in front a screen, tyred your eyes, in addition to some other medical problems.
Then, this technology is reather better.
Yes, and actually your eye sees it as something that is far away. I have seen the laser projections that shoot right to the back wall of the eye and have had the same worries as you.
There are people making curved waveguides, I found a link to their website on Karl Guttag's blog, but I can't find it again.
But you're right, it's very experimental at this stage.
This was the video I was looking for! Thank you so much for the explanation. Your video helped me a lot❤❤
Thank you so much for your explanation . fantastic.
answer my years of question! big thanks
Glad it helped
Cool video!
Thanks , glad you enjoyed it!
Great video and use case of VR. Nice work Andy
Can these lenses be purchased somewhere?
VUZIX.com
Very good explanation! You are a splendid and engaging science teacher. ^‿^
If you _really_ wanna be blown away and get straight to the center of the earth, I recommend searching for the " Principles of DigiLens Waveguides " presentation, which shows a whirlwind tour of the CAD design and production factory for holographic waveguide lenses like these.
