Why can't i watch tv after laser eye surgery?

Doctor's instruction: Depending upon your procedure, your doctor may want you to rest your eyes for a certain period of time.

Give them a rest: Laser eye surgery can cause mild irritation for the first few hours after the procedure. It is also during this time that the eye can feel its driest. Keeping the eye open causes it to become somewhat drier, increasing the irritation and discomfort, and possibly even slowing down healing to some degree.
