In brief: No
Using the computer too much at night will not permanently affect your vision.
However, we normally blink 720 times per hour, but when you stare at the computer this rate generally goes down. This can lead to more rapid evaportation of tears. Dry eyes negatively impacts vision. Lowering the computer screen below eye level causes the upper lid to cover more of the eye and reduces tear evaporation.
