Eyes and studying late in the night

<p>Does anyone know if reading/staring at the computer during the night is bad for your eyes/How bad? I do this 7 days a week.</p>

<p>For the record- doing this causes you to lose your vision at a rapid pace. My vision went down the tube after 9 hours straight for 6 weeks doing a summer programming course so I wouldn't have to take it in a high school slot. MY GOD. Bleary-eyed...just be careful. Equalize light often.</p>

<p>Do you mean temporary blurred vision for like a week or a month or everything is still a blur?</p>

<p>I spend tons of time reading on the computer late at night and do not need glasses. Granted, there is no way you can extrapolate this so it would actually be beneficial to you. Just my two cents.</p>
