Actually, the natural defenses of our eyes might be lowered by wearing contacts because things that go into your eyes need to be sanitized properly. By wearing contacts, you might have a risk of getting eye redness/soreness and styes. You might also have a possibility of getting conjunctivitis. Those make everything complicated, so you might want to consider not wearing them if you have a good eyesight. If you really want to wear, go ahead, but make sure to talk to your eye doctor before and visit him after you get them.
