If I,use Each Pair Of My Acuvue Advanced Astigmatism Contacts For 3 Weeks Each Would It Change My Vision?

Yes….wearing a lens longer than recommended deprives the eye of oxygen. The cornea will begin to swell slightly and grow blood vessels where none should be. The prescription worsens gradually, known as myopic creep, as a result. In the worse case scenario, you grow blood vessels across your cornea so that’s all you see, you compromise the corneal integrity, get ulcers and scars so that lose vision. In short, it is best to wear the lenses as directed….generally 2 weeks for these lenses.
