I also purchased transition lenses and started to see "smudges" and thought it was just dirt. I cleaned and cleaned. It was just a tiny bit at the top of one lens. Much time passed. The original side never got much worse but then the other side started and progressed rapidly. I said that it looked like the lenses were separating and told that "it just never happens." I had now had them about 2 years but had worn them rarely (I mostly wear contacts). Finally it became obvious that they really were separating and I could barely see out of them. I heard from another eye doctor that others had had the same thing happen. I went back to Lenscrafters. They looked at the purchase date and said that the batch had been defective but I had waited too long. My tough luck. At about $400, I had hoped to get more wear out of them. My complaint was that if Lenscrafters knew that the batch was defective, they should have contacted every person who had purchased those glasses, told them of the defect and offered to fix them for free. I also will never go back to that business. If defective cars and other products get recalled, why can't glasses do the same?
