Well... my eyes have gotten progressively worse (more myopic) since I started wearing glasses regularly to work about 5 years ago. This was in my early 30s. Before that I didn't wear glasses most of the time, but I still had some myopia that could be irritating at times. I could still, eg. drive comfortably without glasses. I can no longer do that. It's something that has felt wrong to me, and worried me a lot (you k…
I was prescribed with glasses when I was 10. I flat out not wearing them for many decades. Myopia and astig stay about the same as I was first diagnose. What my grands told me me seems to be true. Not wearing glasses your eyesight won't get worst.
Another anecdote: I developed myopia in high school and college, where it became progressively more difficult to read what was written on blackboards and transparency projectors. I resolutely refused to get glasses. By the time I got my first pair of glasses at 25, my prescription was around -3.25 in both eyes.
Wow, I wonder how you got by. I'm useless when I had -2 or -3 myopia: couldn't recognize people's faces, couldn't read signs. With -3 I think your computer screen even looks blurry.
With significant difficulty! I was very bought into the idea that glasses make your vision worse. By the time I got my glasses, I couldn't read the menus that fast food restaurants post overhead or enjoy board games with friends (requires reading small text on the playing pieces).
This experiment found that undercorrection (giving a prescription slightly weaker than correct) of myopia in children accelerated progression of myopia. https://pubmed.ncbi.nlm.nih.gov/12445849/ . The results appear to have been replicated in another experiment: https://pubmed.ncbi.nlm.nih.gov/16907670/
If we're going to cherry pick studies, according to one line in this more recent study ( https://pubmed.ncbi.nlm.nih.gov/26032395/ ) from the same website: > "The regression analysis showed that myopia progression significantly decreased with increasing amount of undercorrection (r (2) = 0.02, P = 0.02) in all children" Just because you have sources doesn't mean its true. Look at how healthy diets have changed in the…
The two studies I linked were randomized controlled trials. The study you linked was not.
The audience member is correct. Myopia is caused by light entering the eye being focused in front of the retina by our natural lens and cornea, this is usually as the result of increased axial length i.e. elongation of the eye. The dangerous thing about this talk is that the first 2/3rds are true. Reading, looking at screens and working up close as a child and young adult do cause progressively worse myopia by way of…
Thanks a lot for your reply. Yup I got this feeling after the presenter dodged that question. However I also got the impression that it is currently unknown wether the axis of the eye shortens after these exercises, is that true? I read more about the topic and some people call the improvement in visual acuity "blur adaptation" - can "blur adaptation" really produce such drastic effects, and if so - are there potenti…
There is _zero_ doubt that these types exercises can work. I play tennis with a guy that used to wear glasses, with a decent level of myopia (slightly worse than -3), and over the course of several years reduced his myopia to the point he can easily play without glasses (it's something like -0.5 now). The only time I ever see him wearing glasses is at night. He worked off the methods in Bates' "Better Eyesight Without Glasses". I wear glasses myself, and am myopic. I would go through the effort myself, but on top of normal myopia I also have something called Nystagmus (shaking of the eye) of which the net result is additional blurring, so it's pretty hard for me to function without glasses at all (my vision without glasses would be about 20/400, with glasses it's 20/40).
