    That explains why my eye doctors kept telling me to quit focusing on the letters. I was straining my muscles and they couldn’t get an accurate reading on my prescription.
    I think an interesting trait of my hyperopia is I can focus really well if I cross my right eye. It becomes much easier to see details and close objects possibly because my right eye is helping out my dominant left eye.

      Danger, your eyes are about to get worse due to plus lens while looking distance vision. Start playing on your phone or something close up. NO readers, use your distance glasses. Do this for hours a day and you will actually start going near sighted and reverse your vision. How much close up activities do you do?

    If you have hyperopia and wear plus lenses for distance vision almost all the time, your eyes will be more hyperopic soon, just ask someone that is hyperopic and wears plus 😊 Same goes for myopia with a Neg lens, wear neg lens while reading and you go more myopic if its 20/20 vision glasses, Our eyesight changes daily by the thousandth or ten thousandth or something depending on how we use the ole eyeballs, its just ridiculous to think eyes can only change in one direction

  • @kkevinj1
    @kkevinj1 2 ปีที่แล้ว

    People with hyperopia should start reading or smart phoneing ALOT with distance vision glasses on. This is what myopes do. They read or on computer hours an hours a day. Do what they do and you will slowly reverse it. The whole problem is almost all hyperopes do distance vision way more than near work. Watching TV is NOT near enough to stop farsightedness. My eyes go hyperopic naturally so Im going to have to start finding fun close up stuff to do.

    • @turbine2073
      @turbine2073 ปีที่แล้ว

      Sorry but you cannot correct hyperorpia naturally, the only thing you can do is compensate (to some degree) by contracting your eye muscles which is why some people don't get diagnosed until later in life when their eyes cannot sustain the constant correction which can lead to eye fatigue, headaches, trouble focusing, or lazy eye.
      Hyperopia is generally pretty stable and will not worsen until later in life where it will continue to progress as one ages. You should take better care of your eyes as no amount of exercise will truly help and either consult an optometrist and get glasses or contact lenses which can easily correct for hyperopia or even correct it via surgery. If you choose to get glasses or contacts though, be aware that if it is your first time wearing glasses your eyes and brain will need time to adjust the constant compensation of your eyes which can be uncomfortable for a few days/weeks up to a month depending on the strength of the correction but you should be wearing them nonetheless from first thing in the morning to right before going to sleep all day everyday as it will help your eyes adapt more quickly to the correction.

      @@kkevinj1 Here is my evidence, from the National Library of Medicine and National Center for Biotechnology Information -> www.ncbi.nlm.nih.gov/books/NBK560716/ :
      "Absolute hyperopia, which can not be overcome by accommodative effort:
      When a patient can not see 20/20 without glasses, absolute hyperopia is denoted by the weakest plus lens with which the patient can see 20/20." > For some people, it is impossible to compensate for their hyperopia naturally
      "Depending on the age of presentation and the degree of hyperopia, clinical presentation varies from no symptom to a wide range of complaints. Age is an important factor not only due to the ability to express but also the accommodative effort of the patient"
      For an asymptomatic presentation "The patient's inherent ciliary muscle tone and accommodative effort can overcome some degree of hyperopia without creating any difficulty." > It is possible to compensate for one's hyperopia however it does not mean that you can reverse it
      There are two options for the treatment and management of hyperopia:
      "Optical correction: Biconvex lenses (plus) are recommended to converge the light rays on the neurosensory retina"
      "Surgical treatment: Preoperative stable refraction (cycloplegic and manifest)[43] is must at least in three successive checkups one year apart. Counseling and discussion about possible outcomes and side effects are very important."
      The aims of these to options : "Provide good rehabilitation with proper refractive correction, Prevention of amblyopia, Prevention of development of strabismus, Prevention of recurrent eyelid infection and conjunctivitis".
      "The commonest treatment option is rehabilitation with glasses. Regular follow-ups with cycloplegic refraction are mandatory. Adult hyperopic should be treated with glasses or cataract surgery if the cataract is the cause. Unilateral/bilateral aphakia should be treated with amblyopia therapy with glasses or contact lenses immediately followed by intraocular lens implantation. "
      And here are the complications of untreated hyperopia:
      "Amblyopia: Stimulus deprivation or anisometropic amblyopia may take place if there is no timely correction. Proper refractive correction, orthoptic exercises are needed to treat this amblyopia.
      Squint: Convergent strabismus is not very uncommon in developing children with uncorrected hyperopia. The squinted eye becomes more stimulus deprived gradually.
      Angle-closure disease: Hyperopia is a predisposing condition to develop angle-closure disease.
      Anterior ischaemic optic neuropathy (AION): Hyperopia is a risk factor of the development of AION (non-arteritic).
      Retinal vein occlusion: Though few studies denied its association with hyperopia, branch retinal vein occlusion might be more likely to be associated with hyperopia than central vein occlusion.
      Age-related macular degeneration (ARMD): ARMD may be associated with hyperopia.
      Central serous chorioretinopathy (CSCR): Hyperopic eyes may be more prone to develop CSCR.
      Uveal effusion syndrome: Posterior microphthalmos with hyperopia predisposes the eye to develop uveal effusion.
      Nanophthalmos/posterior microphthalmos: Serous retinal detachment, pre-retinal folds with macular cysts, macular folds, and thickening of the fovea and retinal pigment epithelium are common retinal features of nanophthalmos or posterior microphthalmos."
      And for the reason why more people didn't wear glasses a 100 years ago, first of all glasses were less accessible for the masses and 1. the perfection of glasses (their corrective power) is fairly recent with the first corrective lenses being made around the 17th century and 2. people could get by more easily without glasses then than now as school became mendatory for all children only in the 70s (in the US at least) thus requiring the ability to see properly for the purpose of reading, and the inability to do so is one of the major signs of vision impairment.
      So yeah unless you somehow have greater qualifications to talk about hyperopia I'm open to the discussion but otherwise, unless I'm presented with evidence I will not believe that hyperopia can be reversed through "natural exercises".
