When I put one of my contacts in my eye, sometimes as soon as 10 minutes or a few hours later, a cloudy patch appears on a part of it. When I take it out and rinse it, the patch goes away and when I put it back in I can see fine, but then the patch returns. This cloudy patch is not always in the same place. I clean my contact case with soap daily and rinse out both lenses before and after use. This is only happening in my right eye as of now- this had happened before, maybe in the other eye, was fine for a few weeks when I changed my solution, but then returned. My eyes feel completely normal when I'm wearing my glasses. What could be wrong?
