does computer monitors harms human eyes?

Answer 1

they do. strictly due to the fact the cvt monitors project the image towards you. plasma screens or lcd monitors are much easier on the eyes.

Answer 2

First of all no monitor produces gamma rays or can produce gamma rays.

It is possible, if a fault occurs, and the electrons coming down a CRT hit the screen fast enough, to produce X-rays. Every CRT based monitor sold has a circuit in it that shuts down the monitor well before this can happen, this is a DHHS legal requirement.

A monitor will do no direct damage to your eyes, or any other part of you. (unless you drop it on your foot!)


Certain things can cause eye strain:

Too low a refresh rate on CRTs can cause flicker.

Text on black backgrounds cause the eye to change focus frequently as they can not focus on the black.

Characters that are too small.

Continuous attention on a screen can cause you to blink less an your eyes to dry out.


To help stop these problems:
Take breaks, getting up an stretching helps your entire body.
Don't spend too long staring at the screen. Pause a moment, sit back and close your eyes for a second or two.
Drink plenty of fluids. Office environments can be very dry.

Answer 3

It is the Gamma Ray that is produced by monitors' screen that might hurt your eyes. Your best bet is to buy an LCD monitor. That will reduce the damage a lot. Also if you need the monitor to cause less damage, look at its screen from a lengthier distance.

There is an eye-exercise that should be done after 30 minutes of staring into your monitor. Just leave your work for a minute and stare into the distance from a window in your office. Try to blink and relax your eyes.

Good luck.

it's a familiar tale similar to the warnings we received about too much time staring at computer screens taking a toll on eyesight. Now that many of us and our kids are using PDAs, iPods, hand-held game players and cell phones in addition to PCs, we are straining them like never before.

"Our eyes were not designed for the visual demands of 21st-Century America," Andrea P. Thau, an associate clinical professor at SUNY State College of Optometry and an American Optometric Association spokeswoman, told the Wall Street Journal.

Technology companies are working on new fonts and screens to make small letters and images sharper. In the meantime, check out these tried-and-true tips for reducing eyestrain from the Mayo Clinic. Top of the list: Take breaks, and make sure your workstation places your monitor 18 to 30 inches from your eyes.

As for all the hand-held gadgets you may be staring at every day, we may just have to accept that eyestrain comes along with the convenience. Again, moderation is the trick. Don't overdo it. Give your eyes a rest. And make sure your kids don't go from screen to screen to screen.

Have you noticed your eyes hurting more at the end of the day?
