I purchased glasses at Lenscrafters in July of 2015. After less than 6 months the lenses developed foggy spots like water spots on them. When I took them back to Lenscrafters to complain that the lens was defective, they told me that I had to be extra careful when cleaning them. They agreed to replace them. The same thing happened again. Since I needed a new prescription, I went to a different company to get new lenses. They said that I was the 3rd person this week who had to get new lenses due to this defect. I think that the anti-reflective coating on the lens is coming off. Lenscrafters never gave me special instructions for cleaning. I have worn glasses for over 40 years, and this has never happened. Also, I have never paid that much for lenses at any company.
