well explained! Thank you !

Goof afternoon. Sorry I have 55 years old and I have anisometropia, to play tennis is difficult, ¿is there some solution? Many thanks!

This must be the best explanation of Fuchs ive seen on the internet yet. Many thanks for posting.

A great study. Soon, we will be helping pilots go from 20/50 to 20/20. Can you help us?

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.

Impressive. Takes time!

Difficult subject. I prefer my objective measurements.

20/50 is illegal to drive in most states? What?

Thank you!! Studying for my COA and this really helped me!

Is this dye fluorescent can cure the eye Eye wound can fix ?

I have a prescription -3.00/-2.00 x90 with K readings 7.80mm @ 180 and 7.40mm @ 90 - is this WTR or ATR - I believe it is ATR

Excellent tutorial!

Concise and informative…thx

thank you for this amazing video! simple and easy to understand!

explain pretty well about WHY, not only how and what.

The last slides concerning the contact lenses are blemished and have no legible text.

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

tysm

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 studying to get my NCLE and this is very useful!!! I appreciate it!

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?

I need to order this... Plz share vendor number if u have, i m in Moradabad india

What type of eye doctor would be able to resolve these issues? I go to a big box doctor and they have no idea how to fix it

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.

Thanks so much, excellent videos and content.

Christopher you gave a great voice. Maybe try as a book reader or narrator.

This channel is more helpful than the hundreds of office visits we've had all put together

A different of refractive state, between two normal eyes, @ 1 Diopters.

Hi Chris, This is a good idea, to verify. I do not complain.

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.

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.

Wrong. We know in 2022 what the correct theory of myopia is.

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.

Emmetropization, is a convenient myth. It is an out growth, of Kepler's assumptions and theory of the eye.

Now I understand astigmatism better. Thanks. 😊

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?

Bates's Rocking can lead to emmetropization?

Nice video! What do you think about reading glasses (for example one with two +1 sides) to prevent myopia from developing while (students) are focussing on things close to their eyes?

The eye controls the lens, as feedback, to micro blur on the surface of the retina. Check the science, please.

Correct. All fundamental eyes "emmetropizes", on their average of accommodation.

The normal eye is controlling its refractive state, to changes in its average level of accommodation. All eyes are sophisticated control systems.

Use an electronic Snellen, but keep the 50% judgment.

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

I enjoyed your content a lot! I've been trying to look for CZcams video like yours that informs the topics in this CZcams video. 👍 👩‍⚕️Your explanation really is like the videos from Dr. Ethan. His explanations are insightful and he helped me on my midterms. He is a helpful medical student in Europe! I recommend you check his YT out and give Dr Ethan a like! 👉 #DrEthanEducation
