Has anyone ever had this problem where when you don't sleep the night before.?

Question

You start to see things a little blurrier.Anything that has to do with light computer , cellphone etc.

Answer 1

well an explanation to the blurryed vision maybe that you are sitting too close to a large computer screen for an extended period of time and for the cellphone it maybe that you are trying to focus your eyes upon extremely small writing (text messaging)...when you are sleeping it is very important to have it as dark as possible because your eyes naturally focus on any light
