Lenscrafters Defective Anti-Reflective Coating Reynoldsburg Ohio

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.
