SUMMARY

The discussion centers on the impact of different monitor types on eye health, specifically contrasting LCD and CRT monitors. Users report significant eye strain and deterioration in vision when using older tube monitors, while LCD monitors are noted for being easier on the eyes. Recommendations include checking the refresh rate of CRT monitors, with a frequency above 75Hz suggested to reduce strain. Participants emphasize the importance of taking regular breaks from screens to alleviate eye fatigue.

PREREQUISITES
  • Understanding of monitor types: LCD vs. CRT
  • Knowledge of refresh rates and their impact on eye strain
  • Familiarity with eye health and common vision issues
  • Basic awareness of ergonomic practices for screen use
NEXT STEPS
  • Research the effects of screen time on eye health
  • Learn about ergonomic setups for computer workstations
  • Investigate the benefits of blue light filters and anti-glare screens
  • Explore eye exercises to reduce strain from prolonged screen use
USEFUL FOR

This discussion is beneficial for computer users, IT professionals, and anyone concerned about eye health related to prolonged screen exposure.

When I bought my new comptuer, it came with a nice LCD monitor. My understanding is that these LCD's don't refresh. They only refresh the pixel that changes; therefore, they are much much easier on the eyes. I find looking at this flat screen highly tolerable. But the LCD is on the computer downstairs my parents use. I use the newer computer upstairs, but with the old monitor. That monitor is a tube monitor, it's not LCD. I sware there is something about that monitor that is causing my eyes to go bad. I've been using it for a few months now, 4-5, and I think my eyes got very bad. When I was using the LCD for some time, I had no problems. When I switched back, my eyes turned to trash. I don't know what happened, but now I can't even read street signs, you know, those big ones on the beltway.....:frown: I could also read my book with my glasses off from 3 feet away, now I have to press my nose into the pages. Past 1 foot and my eyes become out of focus. I used to be able to take my glasses off and see, but not very sharp. Now I can't even see my hand if I stick it out. Its all a blurry mess... It's not so bad during the day, but at night time it's not good. I bought a new flat screen from dell to replace that old minotor. But I thought I saw something on TV saying that they just cause eye strain, but not irreversible damage. I don't know if its just severe eye strain or not. Sometimes it feels like my eyelids are twitching a little. My glasses are going to be upgraded to telescopes. I hope it goes away soon...hah yea right...I hope its nothing serious like diabetes. That would not be good.

You should make sure to regular breaks from the computer to rest your eyes and focus on something far away.
 
But most of my time is not looking at the monitor, its reading my book. And I read off and on, so the breaks are already there.
 
Reading a book isn't much different from reading your monitor. You're still focusing on something close so you're not really giving your eyes a break.
 
I said I read it off and on.
 
Oh I thought you meant you would alternate between reading your book and being at the computer.
 
What can i say but...

Crazy cyruses always getting into trouble
 
Blindness is not funny...
 
You know, I have been wondering if my LCD screens are causing eye problems. There is no doubt that my eyesight has taken a big dive over the last year, and my sense is that the computers are part of the problem. Of course I'm staring at a computer almost constantly these days...

My LCD is not the problem, its the tube monitor that's the problem. I find the LCD much easier on the eyes.

CRT monitors are definitely a problem. After a while, my eyes would hurt. With this LCD... geez i could stare at the computer for a day and nothing would happen outside of me being tired :P

Check the frequency of your CRT monitor. If it is 60Hz then that is the problem. Recommended frequency is >75Hz. To reduce strain on your eyes increase the frequency and reduce brightness.

I don't know how long you guys actually spend on the computer, but I have a old style monitor and my eyes are fine.

I thought they got weaker, but I guess I was wrong when I was studying with my girlfriend and her friend. I was sitting across the table and I mentionned something about their work after reading the paper they had on the table. Then they were like shocked that I can read things that small from so far away. I guess I'm ok.

I went to the eye doctor no more than 2 years ago and I had 20/20 so I know I'm not near-sighted.

I can't say that I know anything about your problem but I can say that my Dad's old monitor is really hard on the eyes. I used that thing for years before I finally got my own laptop. Its screen is really clear...I used it for a few months before having to switch back to my Dad's computer when my laptop stopped working. God, that was horrible...I never realized just how bad his monitor is. Everything was blurry and I had to blink several times to get my eyes to adjust. It was like as his computer's monitor got worse, my eyes just went right with it.:bugeye:

I've been looking at things for a while. Even hazardous things, such as computer monitors, books, and the body of a naked women (in both). I have not noticed a decrease in visual strength.

After years of being a hardcore computer user, my eye-sight have gone bad. I became nearsided because of computers, heh.
