I had bought my glasses one year ago. Recently, I noticed the special coating To prevent glare was peeling.Because I have been washing my glasses with hot water, which is a no no I was the culprit.I was ready to pay to have new lenses put in, and to my great surprise they offered me new lenses at no cost. And walked away from there thinking that was great customer service. In todays world customer service is not at the level I have experienced in my lifetime in the past. So this one kind, thoughtful gesture has move me to be a loyal customer.
