Can safety glasses affect your vision if you where contacts?
They could. Generally, nonprescription safety glasses have plano lenses, which mean there is no prescription to effect your vision. But, most of them have a general optical center (the part of the lens with the clearest vision). If you went to an eye doctor and got a safety pair of glasses they would measure this optical center to make sure you are getting the clearest vision possible. Glasses with a general optical center do not account for people who's eyes are close or far set. If you were not looking through the optical center it is possible that you would notice some distortion in your vision (nothing to extreme, just not quite clear).
