The glasses didn't work yet they fought us every step of the way. We finally had to file a claim with our credit card company. We went to our optician twice to determine why these lenses weren't working. Both times, they were found to be measured improperly. We offered to send the lenses back and keep the frames. Still, Paris Optique refused to budge. They are helpful and friendly through the buying process, but good luck if you have any issues after they receive your money. They are unreasonable and use the "no refund" policy to protect themselves from shoddy workmanship.
