can computer screens damage vision?

Answer 1

Yes very much so.They have eye savers you can buy to place over the screen for protection at most computer stores.

Answer 2

There is no evidence of physical damage to the eyes due to prolonged reading from a computer screen. However, it has been demonstrated that most individuals do not read as quickly or as efficiently from a monitor in comparison to reading hard copy.
The most common complaints are the following:

dry eyes
eye strain
blurring
These complaints are often associated with headaches and neck and arm discomfort.

Answer 3

Yes, particularly if you use them in the dark. If you are using a CRT screen you should also sit 3 times the height of your screen away from it, the jury's out on whether this also applies to flatscreens. With any screen you should take occasional breaks to focus on something else in the room, and always remember that you're staring into a light. Looking at the sun may burn your eyes out fast, but staring at any light source will do it given enough time.

Answer 4

While computers have no known harmful effects on eyesight, computer users do often complain of eye related symptoms such as eyestrain, headaches, fatigue, dry eyes, and difficulty focusing, These symptoms (Computer Vision Syndrome - CVS) however are caused not by the computer screen itself but rather by the conditions surrounding the computer screen, such as poor lighting or improper placement of computer equipment and computer furniture. In some instances, a pre-existing eye problem may be the cause.

Answer 5

Yes they can. Always keep the refresh rate as high as possible (only choose the highest that is compatible with your monitor or you will eventually destroy it). If you have a TFT screen you should choose 75hz.

Follow these steps (Windows XP)

Right Click the desktop
Click Settings
Click Advanced
Click Monitor

From here you can choose the correct refresh rate. As mentioned the higher the refresh rate the better it will be for your eyes. Anything above 70 (TFT) and 80(CRT) is fine.

Answer 6

Only if you stare at it for long hours. TV damaged my vision. That's why so many people have to wear glasses or contacts now adays. Back then when they didn't have all these sophisticated gadjets people did worthwhile things and kept their eyes strong. And now they are creating small Ipods and cellphone to aid in vision reduction. I beleive it's a conspiracy so the eye doctors and gadget makers can get rich.

Answer 7

Absolutely they can, in fact anyone working with computers should be made aware that it is a legal requirement for their company to offer free eye tests and carry out risk evaluation checks on all VDU equipment.

There are Health and Safety regulations in place, go to the link below look for the heading

What do employers have to do to comply? Section 4.

Answer 8

Health and Safety (VDU) Act 1992 based on BS 7191 recommends breaks after 40 minutes from VDU use. Other factors such as the workstation area, seating and lighting also matters.

Answer 9

If you are careless yes. Look after your eyes by blinking to stop them drying out, sounds daft I know but when using a computer monitor people tend to blink less. Also ensure you glance at other things periodically at varying distances so your eyes can focus on something else before continuing. Take breaks. This all helps.

Answer 10

oh yes over 1hr on computer will mess it up so every 1 hr, get up and move to somewhere else like look out window for about 5 min.
