question: Hello doctor, I am 16 years old, and I wear contact lenses. I have never really taken them off. I would sleep with the contact lenses in my eyes and I have started wearing them since I was 13 years old. I would change them, but I would not take them off, and I would go days. My vision gets worse when I go to the eye doctor, but I have not had problems with infections. Recently I noticed that my left eye is red without pain or irritation, but red as the color of the pink eye. I do not know if it is the contact lenses which is causing the redness. Please help.
