   Glasses
  Do you wear glasses ? Like prescription glasses? I ask because I find myself staring at the computer all day long, and it hinders my eye vision. Iassume that sooner and later I will need glasses.   
  I've been staring at my computer screen for like 20 years and haven't needed glasses or contacts yet.  It doesn't seem to be degrading my vision, at least.   ;  Been working with computers, at a rate of probably 12 hours or so a day for the past decade and I have 20/10 vision :)   ;  Yeah, I wear glasses. Hoping to get laser surgery at some point in the future, but right now glasses for the majority of the time and contacts for sport.Back in the old days of CRTs I started getting an anti-reflective coating which made it easier to work on a computer for many hours a day. LCDs apparently aren't as bad, but I still tend to get the coating   ;  I've worn glasses my whole life. I'm near sighted with astigmatism so everything is blurry without them. Never really thought about them since once you get used to glasses you don't realize they're there. Also my glasses are transition lenses which if you know anything about them totally rock. (Instant sunglasses except in cars which isn't much a problem). My eyes have stabilized basically so I could get laser, but I look good it them so I probably won't.Even if you don't' think you need glasses go get an eye check. My dad was surprised how much he needed reading glasses. He's really happy he went and got his eyes checked.Also as mentioned just get laser eye surgery if they say you can get it. They can turn almost anyone's vision into perfect vision nowadays.   ;  Medically certified 20/20 despite looking at monitors with tiny fonts far more than can be healthy.  I do wear sunglasses though -- while bright light doesn't hurt my eyes, it does cause an involuntary squint which gives me massive headaches.   ;  It really depends on what you're looking at on the computer screen.  Some of that stuff will make you go blind and grow hair on the palms of your hands.Seriously, you need to take a break every 20 minutes or so and focus on something far away for a bit.  People don't blink often enough when using computers, either.I've been a professional programmer for 25 years.  I do not need glasses any more than I did in University.  Okay, maybe reading glasses, but that's age not using a computer.  At least I don't need progressives like my wife....   ;  After you hit adulthood, it doesn't matter how much time you spend in front of a computer. It won't affect your vision permanently. I got LASIK 2 years ago and specifically asked about this, because I definitely did not want to pay all that money and then become nearsighted all over again.Staring at a monitor might make your vision blurry or dry your eyes out temporarily though.   ;  Despite the few responders with perfect visions even after years of occupational or unhealthy eye usage, I would assume they are the exception rather than the rule?My vision started to progressively worsen during high school. I associated it with the frequent late nighters either playing games and studying/cramming each week. Worse life style persisted in college, sometimes sleep deprived for days.The past few years the worsening vision seems to have settled down. But then again, working is a lot less stressful than school, and I binge-game a lot less.But I also heard, even if I led a stress free life without school or games, my vision would have likely gone downhill anyways as a matter of aging and genetics. What's the contemporary wisdom on this?Btw, I still don't wear glasses or contacts. I pass the driver's vision test but can't make out others' license plate # if more than two car lengths away. Similarly, people's face become a blur. If I attend conference lectures, I must sit in the front and still struggle somewhat to read texts on slides.   ;  As far as I understand:Near sightedness is a growth defect during the development phase of the eye. The eye grows into proportions that changes the refractive properties outside of what the lens system can correct. Using computers a lot, but also reading a lot in early childhood can worsen the situation. If you don't grow anymore as an adult, it can obviously not change anymore, regardless of what you do (except for physical trauma and the like). That's why you shouldn't do laser surgery as a kid, when you're still growing.Age related far sightedness come from the lens losing flexibility, so that the muscles cannot bend it enough to cover the full spectrum of refractive indices anymore.
