I wore glasses for a few years in high school because I had trouble seeing the blackboard from anywhere but the front row. I started hiking and kayaking every day, especially in places where I could see for many miles. I also migrated from CRT to LCD to LED screens, and more recently to e-ink devices when possible. Very fine print in a dark space is hard to read, but I can read a moving US license plate from six bloc…

Sunlight exposure has been shown to be protective of eyesight, and we spend more time indoors focusing on screens. The timespan is too short for evolution to have had a considerable impact.
> The timespan is too short for evolution to have had a considerable impact. I am not talking about evolution as in developing new species but about survivability of naturally occurring variations. Modern humanity timespan is not enough in developing new genetic traits but long enough to alter effects of natural selection. BTW, due to advances in medicine nowadays we have children born and survive into adulthood with…

It's more likely that it works for a large majority. If you were born myopic or had an accident or something similar, yea it most likely wont work for you. But most myopes do not fall in those categories. I'm very open to hearing your arguments backing up your statement though.
My arguments are that if that were the case, we'd already be doing it. I work in the optical industry. To suggest that opthalmologists just haven't figured this out yet is just pants on head retarded, sorry.

We live in a world where not long ago smoking was considered fine by doctors. Where fat is demonized on nutrition labels while obesity surges. Where leaded gasoline was banned in gas not that long ago. Where a dozen diseases are increasingly prevalent and we have no idea why. To suggest that medicine hasn't figured something out is completely sensible. It can be argued that mRNA vaccine breakthroughs might not have h…
Re: Shortsightedness has become an epidemic
#366The different usage of words and their meanings in English is interesting and makes me think this weird miscommunication is why we have so many arguments. In my everyday, the article would be referring to nearsightedness, short sighted would be when someone doesn’t think through all the possible things, lacking foresight. By definition it’s both but in every day use it’s not.
Re: Shortsightedness has become an epidemic
#367My child is following in my footsteps and has been prescribed glasses for nearsightedness. Her optometrist told us she should be watching TV rather than reading books. This was both surprising and upsetting, especially since she loves reading. This lead me on an interesting deep dive into existing research. What surprised me were the massive gaps in understanding. Scientist have at best established correlation betwee…

#368Everything in nature is fractal-shaped, while most things in our artificial environments are made of flat surfaces. If you think of light as a kind of "food" for the eyes, we are effectively eating junk food all day every day.
Lol that's just rediculous.
It's a metaphor. Eyes evolved to process much more intricate light fields than we typically get in our homes/schools/offices. That has an effect?
Re: Shortsightedness has become an epidemic
#369In my early teens I had 20/15 vision. By the time I went to college I was wearing glasses for nearsightedness. I'm pretty sure it's because I got interested in computers, and started spending all day staring 3ft ahead instead of glancing around outdoors. Some friends in my computer science program passed around each other's glasses and found we all had nearly the same prescription. That didn't seem like a coincidence…
Gross generalization, but my suspicion is that it’s not the all day staring at computer (that’s most adults these days) but also many CS types spend their free time in front of a screen as well…

There's just no evidence for it. It's that fucking simple.
The main thing, axial length reduction through undercorrection, has been shown in plenty of animals and humans.
