Is staring at a computer for long periods of time bad for the eyes and are there long term consequences?

Not really: Computer use does not really cause any eye problems, but long term use may be associated with eyestrain and dry eye. Making sure that the computer is at a reasonable distance from you, varying the viewing distance, and periodically taking breaks and looking away from the computer can help prevent eye strain. The blink rate can decrease with computer use, so artificial tears can help if needed.

Computer use: Computer use will cause the eyes to get dry during this time but will cause no permanent damage. You can try artificial tears as needed and take short breaks to prevent these symptoms.
