I think all the members here stare at computer screen for more than 3-4 hours a day. For me, it is more than 5 hours a day. So I started to get worried about my eyes, whether I can still see things when I am 30 ( now I am 23... ) So could you plz tell me how you protect your eyes?

I just move around alot - plenty of cups of tea

Oyasumi nasai

(I'm not sure Ive got he right versions of hello , goodbye - day night ?)

Well, I'm at the computer maybe 15 minutes, then I get up and do something else.

I used to stare at a radar scope 4 hours on four hours off for a 12 hour flight (24 hours off after a flight) for several weeks at a time when I was a scope dope in the U.S. Navy in my 20s. I needed reading glasses at 46 and I got bifocals 10 years ago.

If you live long enough, your lenses become cataracts and that can be slowed down by avoiding ultra violet light/wearing uv blocking sunglasses.

I don't worry about monitors.

To keep maximum lens flexibility, you need frequent changes in your visual focal length, so spend minutes, not hours looking at the screen.

Ya you have got konnichiwa right but it is still daytime in Japan. So "oyasumi nasai" (good nite) sounds funny :P
thanks for your advices

Osu.

I've wondered about this sorta stuff myself. I think the best trick is to keep the lights matching the luminosity of your screen. Your eyes strain looking at contrasting brightnesses...

*turns the lights up* Should practice such behavior.

Also, probably dump the CRT, if your going for safety. Probably not the best idea to sit TOO close to an electron gun...

demo, muri shinaideyone?

If they ever make glasses that help, I'll be wearing them 24 hours a day.

Caidence. Anime o miresugiru, watashiwa.

(ignore this, just testing something)

I don't have a clue, but I just turned 30 not too long ago, and I'm not blind yet. Well, I am blind, but I've been nearsighted since before I started using computers at age 10.

Lighting is probably the big thing. The glare from the overhead lights bothers me more than the screen itself. The last place I worked they had lights up high and then they had something so the light was diffused so it cut down on glare. The current place I work for has the lights at about the 9 foot level and I can't stand to look at the screen all day.
Take some breaks visit the water cooler

Actually a computer moniter does not pose a substantial risk to your sight. As long as you have decent lighting in the room, you can spend many happy years in front of your computer. BTW, I know this because I actually asked my doctor once.

I spend 8 to 10 hrs a day at the computer and I've found that if I get up and walk around every couple of hrs it helps. Also, during your time out try focusing on something far off.

Having a good glare shield also helps

I'm using a LCD screen and as far as I know it doesn't hurt my eyes. I spend 12 hrs. at day in front of this thing. I try to stand up every while to drink something, walk arround, etc.

I protect my eyes with my glasses.

I spend almost 20 hours before my computer because I have nothing to do.

While it may be true that computer screens are not "dangerous" for the eyes, CRT's can cause significant eye strain due to the fact that the actual image is as much as 1/8 - 1/4 inch behind the surface of the screen. Depending on level of fatigue, dirt/dust on the screen surface, or glare from ambient lighting, the lense of the eye will start to shift focus from the image to the surface and back again leading to further stain and headache. Combine this with improper refresh rates and you have one hell of a headache. I would imagine that the constant lense shifting over extended periods over several years would eventually weaken or permanently fatigue the muscles of the eye responsible for shaping the lense to focus. That being said, most people lose the ability to focus on close objects due to the hardening of the lense with age. Where to assign blame in any one case is a hard question.

This is one reason why I find LCD screens far more pleasent to work on for extended periods.

Otherwise, frequent breaks are the rule.

cheese. cheese is the answer to everything.

I'm sorry sk8guitar, but without tea there would be no cheese.

Tea is the answer. Cheese is the next vital step. Then you can take on anything...

pass the crumpets!
