Terrible experience. Negative attitude about bring in your own frames to have just lenses. The lenses lasted 2TWO days. I put the glasses in my pocket and they came out so scratched that the glasses were totally useless. BJ’s said that brining in your own frames voids any warrantee on the lenses. Another Optical shop examined the lenses and told me that they were made from a very cheap material(polymer). Penny smart/dollar foolish. DON’T USEBJ’s OPTICAL. I’ll keep you all posted on how the new pair fairs up.
