Laura Fine, Ophthalmology, answeredAlthough using a computer will not harm your eyes, staring at a computer screen all day will contribute to eyestrain or tired eyes. Adjust lighting so that it does not create a glare or harsh reflection on the screen. Also, when you're working on a computer or doing other close work such as reading or sewing, it's a good idea to rest your eyes briefly every hour or so to lessen eye fatigue. Finally, people who stare at a computer screen for long periods tend not to blink as often as usual, which can cause the eyes to feel dry and uncomfortable. Make a conscious effort to blink regularly so that the eyes stay well lubricated.

Looking at computer monitors will not harm your eyes. Often, when using a computer for long periods of time, just as when reading or doing other close work, you blink less often than normal. This reduced rate of blinking makes your eyes dry, which may lead to the feeling of eyestrain or fatigue.
Try to take regular breaks to look up or across the room. Looking at objects farther away often relieves the feeling of strain on your eyes. Keep the monitor between 18 to 24 inches from your face and at a slight downward angle. Also consider the use of artificial tears. If your vision blurs or your eyes tire easily, you should have your eyes examined by an ophthalmologist.
