  In the living eye, accommodation does not stop or relax. It is continuously adjusting based on micro blur detected at the surface of the retina.

  I always verify I read letters correctly. I use test lenses to establish my refractive state. All values are objective and repeatable. Refractive status, +0.5 Diopters. Snellen, 20/20.

  0.25 Diopters. 20/60 to 20/20. About -1 Diopter. Use your own test lenses, please.

  My right eye needs power +7 but my doctor gave +3 after decreasing several time.And left eye glass power is +.50. I have difficulty focusing. While I try focus or study my vision become blurry and crossed most of the time. Will you please tell me if contact lenses will solve this problem? 🙏

  I'm not a optometrist student. I have high myopia -6 on both eyes. Recently I went to hospital for biometry to know that I'm a good candidate for LASIK or not.They said that i have good corneal thickeness to go for LASIK. But they told me that my axial length was too long so it will probably leads to myopic regression after few years. From then I'm freaking out to know how much it was more than 26mm?

  do you think axial length can be reduced as an (early) adult with hyperopic defocus? there is a internet sphere called endmyopia and also a youtube channel which also has many people reporting that they have reversed their myopia this way.

  A. Camera Eye is a complete myth. The fundamental eye, controls its refractive STATE, to its average of Accommodation. See putting a -3 Diopters, on a totally normal eye. Predict it refractive change, for the next three months. Now with the same eyes, put a +3 Diopter on them. Not, Predict their refractive state charge.

  @otiebrown99992 жыл бұрын

  The only "visual guided growth ", comes from the Accommodation systems. Ie, all eyes are sophisticated control systems. A Truth you must totally deny. Even you apply a step function to the Accommodation system, the fundamental eye changes its REFRACTIVE STATE, accordingly. Your "Emmetropia theory ", is disconnected from objective scientific reality.

  All normal eyes, do not have "refractive errors" they have measured positive and negative refractive STATES. That is the only objective measure, a scientist can ever make.

  Thanks for your review of refraction. I now do my own refractive checking. Far more accurate than a 5 minute visit. I am not your patient, so must make certain to always verify 20/20 on my Snellen. Making certain that any refraction I have is Spherical.

  if the eyeball only elongate then why farsighted people's eyeball shorten?

• 
  @briansun6336Ай бұрын

  They don’t. Their eyeballs are born shorter than normal and as they age their hyperopia reduces due to the elongation naturally occurs while a person matures. Hyperopia doesn’t get worse, but if someone is born with a big amount of it, amblyopia might occur.

  Not an accurate model. "Emmetropization", is wrong. No normal eye ever does it The eye never was a convenient box camera, for your analysis. All eyes control their refractive STATE, to their AVERAGE of Accommodation. All normal eyes change their refractive STATE in both directions. (See pure, un-biased scientific research for confirming. ) See: Otis Brown and Dr. Antonio Medina
