Why do your eyes hurt after using the computer for awhile?

Eyes begin to hurt after a time on the computer because you tend to blink less and so they become dry. So, look away periodically. You can also use liquid tears as needed--avoid the red out variety since you will end up with a rebound feature. Also, if there is a glare to your screen, you can reduce it by adjusting the monitor contrast. Eyes begin to hurt after a time on the computer because you tend to blink less and so they become dry.
