What are the books at eye doctor exams used to prove for vision with the optical illusion numbers?

I believe you are talking about the color blindness tests where the numbers are written in colored dots. Basically if you are not color blind you will see the numbers but if you are color blind then you will only see a bunch of dots.

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).
Do optical illusions still work if you have contacts on?
Optical illusions are usually not a function of optics, but rather a function of how your brain interprets the patterns of what it sees. As long as you can see the picture or object clearly, you will probably see the illusion. It doesn't matter if you have perfect/normal vision or if you are wearing corrective lenses.
