A guest asked Dr. Oz why her eyes get irritated sometimes when she wears contacts. Dr. Oz explained that over time, contacts can cause tiny rips in the eye. So if your eye is feeling irritated, give your eyes a break and wear glasses for a little while.
Contacts are foreign bodies, and so your body want to get rid of them. Thus, you have to be very careful that you clean your contacts well and check that you do not get an eye infection.
