Activities that Mess Up your Sight

Well I will have to admit that I do some things that may cause damage to my eyesight. For one I sometimes don't care how close I am to the any electronic screen. Sitting to close to like computer screens or TV screens can damage your eyesight even though everyone does it. Also I use to look at the sun trying to see what it looked like before and that caused harm to my eyesight. I don't always wear sunglasses when I am out in the sun even though they say you are suppose to. I also keep my contact lenses on at night even though I am suppose to take them off every night and put them in a solution. Right nwo I'm starting to see blurry and I am not sure if it is because of the contact lenses or my vision getting bad. Maybe it is time to change them. Apart from all of these things there are probably others things that I don't know of that damage my eyesight.
