This is actually rational discrimination. Excessive near-work literally causes myopia so one should deduce individuals with glasses have spent more time in front of a computer.

LASIK/PRK laser correction is only a few thousand dollars. I haven’t had myopia since I was 25, and I should not need (reading) glasses again until 45. And of course, contact lenses.

  The latter part is true, just FYI for anyone, you do need reading glasses eventually post-Lasik. I had it at age 29, and now at age 45 (and starting around 42) I do need reading glasses for anything closer than about a foot.

  I looked into it when I was 20 and decided that the risk were not worth it. Of course things are probably better 25 years later, I haven't checked again. But then again at almost 50 I now cannot work at a computer without reading glasses and surgery still can't fix that. A large part of the risk for me was I discovered I can get prescription safety glasses, and if I can't see without glasses I will never risk forgetting to put on safety glasses when I need them.

    As far as I understand, there are very few risks these days. You can even move your eye around while the laser is shaping your cornea, since the laser has the ability to keep track of it and move along with the eye. One of the best decisions I ever made, in terms of making life more convenient, especially physical activities.

    >surgery still can't fix that. As far as I know, they can adjust for reading distance but you may have to make a choice in terms of what they distance they optimize for. I know people who got surgery after 40 (when your lens tends to be less pliable) that had one eye set for near-sighted and one for far-sighted.

> Excessive near-work literally causes myopia Evidence shows that not getting enough sunlight when young is what causes myopia, as there is a gene involved in stopping the process of natural eye lengthening that is enabled by sunlight. This need not necessarily correlate to excessive work, as children don't play outside for a variety of reasons.

  afaik the jury is still out on this. There is a lot of correlation, but the causal relation is not widely accepted by science yet. Happy to be shown otherwise!

  I hope this is being studied intensely in Finland. It has both a strong IT sector and a practice of ensuring kids have plenty of outdoor play/free time.

  Can't be the only cause though -- I have a -6.0 diopter prescription, needed glasses starting in 2nd grade, and I was outside a lot as a kid (grew up in the 1970s -- staying inside was boring).

I spent my entire childhood reading, my teen years hacking, and my adulthood as a software engineer and gamer. I've spent my life doing all the things mom warned you about. I'm in my 50s and still have 20/20 vision.

  Funny you say that, as I just got back from an eye appointment and in my 50s also still have 20/20 vision (after more than 40 years of programming/staring at the screens).

  Thats great. You might be one of the 9 coworkers in my org that do not wear glasses or contacts as far as I am aware in an org of 80 - 100.

It's a statistically correct bias. That doesn't make it ethical for hiring.

And you might go and hire the person that makes sure they always look like they're working over the person who can actually get the job done without breaking a sweat and clock out early.

That's not how myopia works. I had glasses prescribed in childhood; the only thing causing that would be genetics or a couple hours of video games a week.
