Q: I’ve been wearing contact lenses for years. Now, they hurt every time I wear them. I think I have a bad batch. A: If you have some contact lens-related inflammation in your eye, then it’s possible that every contact lens will feel bad. Your eye doctor will check for inflammation, infection, chemical sensitivity, and allergies, all of which require different treatments. This might be urgent too, since some of these problems can be very problematic for the health of your eyes.
