Anecdote: I used to get new glasses/prescriptions every year. Every year my prescriptions would get stronger. Last couple of years I stopped renewing my glasses and whenever I absolutely need to get new glasses, I have the store use my old prescription. For whatever reason, my eye sight stopped getting worse. I think by wearing stronger prescriptions, your eyes adapt to it and you get more and more myopic.

Studies of deliberate undercorrection show a slight acceleration in myopia progression. Myopia progression slows and stops naturally after adolescence, whether you wear the correct prescription lenses or not.

I got myopic in my early thirties. It was annoying, up to that point I was the only one in the family without glasses. Still don’t like to wear them.

From tons of articles, medical advices, etc. that insist that "you don't develop myopia from reading, monitor work, video games, etc". They not not say that it's "purely genetic", but that's the impression one gets, that all those lifestyle params don't play any role... Wikipedia says it's "a mix of genetic and environmnetal factors", and includes all of the above factors I've mentioned. But I've read many times in t…

> From tons of articles, medical advices, etc. that insist that "you don't develop myopia from reading, monitor work, video games, etc". As an adult, it would certainly be an outstanding discovery if this did matter. Which is why I'm skeptical about these supposed glasses. Sounds like snake oil, quacks like snake oil. For children, teenagers and young adults: maybe. It's all about the eye shape, and children's bodies…

>As an adult, it would certainly be an outstanding discovery if this did matter.

Why not? It's not about being "still in development".

All of our organs (heart, liver, knees, joints, ears) can deteriorate in various ways if we don't take care of them or abuse them in certain ways as adults (e.g. ears and loud music, especially on headphones, can lead to reduced hearing). Heart, well, we can have the heart of a 80 year old at 40 if we have the wrong lifestyle.

So why not eyes as well?

(Not to mention myopia usually rises over time in adults that have it - and they change glass perscriptions etc.), so it's clearly something that develops in adulthood too. Not to mention other things related to the eyes and their plasticity etc., like presbyopia, that strike at ~ 40-45 or so.

That's tricky. The 'light' version certainly helped also with different applications other than just books and screens and I used them in the car regularly, but the higher ones are useless for that because I can't keep all of the interior bits of the car in focus at the same time as the outside world so I drive without glasses, it also significantly reduces my dead angles due to improved peripheral vision. So there m…

You probably always had some mild hyperopia that you were able to accommodate, but you lost that ability due to presbyopia. Perfectly natural. I would really recommend getting some multi-focals or to look into other solutions such as monovision.

Thank you! I will definitely take that bit of data along to the eye doctor, it makes good sense.

Ask yourself, how much brighter is it outside than inside (assuming a sunny day vs a brightly lit office)? Before looking into this, I would have guessed 2X or 3X, but would you believe it's actually over 100X! I bet most people's guess would also be off by 1 or 2 orders of magnitude. Even outdoors in the shade, it is over 50X brighter than indoors. (For specific numbers and comparisons, see: https://www.ncbi.nlm.nih…

The study was done in Singapore and Malaysia. It looks like an interesting study to do in different regions of the world. e.g Western Europe where it is notably cloudier than Singapore.

Before you change your internal mental calibration, this of course changes based on latitude and time. The difference between daylight and a cloudy day midwinter in Northern Europe is probably not going to be 100x.

I was in agreement until this.

Doesn't this defeat the purpose of being outside? To actually use their eyes to see things near and far, run about and get those muscles working? I don't know what it is about modern parenting that seems wholeheartedly dedicated to the task of making children worship at the altar of Disney and Youtube while denying any chance of developing mental and physical toughness.

Just as a side note, its not that people are terrible at perceiving brightness, it's just that brightness perception (like loudness) is logarithmic. So if a person says it is 2x brighter outside, and a linear measurement instrument says it is 100x brighter, that is in fact roughly consistent.

The whole point of the comment is that time outside matters more than what is done outside. I don't know the degree to which this is true but if you're going to watch something anyway, doing it outside instead of inside seems like not a bad plan. I don't think they intended anything by specifying tv and you could replace it with reading, board games, drawing, any activity commonly done inside.

Okay if that's the case wouldn't you see similar result if kids watch at a sunny window. Light wise that's pretty similar.

My parents had corrective eye surgery in the last decade (corrected their myopia), and they claim the eye surgery damaged their "reading vision." They lament the loss of their reading vision, and I have to keep explaining that they're experiencing presbyopia and not some damage the surgery caused. My myopia is pretty bad (-9.25 and -8.5 in contacts), so I don't even get the benefit of reading without correction.

For a disease which affects literally everyone as they age, presbyopia is astonishingly unknown. I didn't hear about it at all until I started working on VR and eye tracking.

Pretty much everyone knows their eyesight will get worse with age. It's just that most people refuse to admit they're getting older.
