Very easy to order, I was concerned that I was not going to receive them within 2-3 days because of the Covid virus. As it turned out I DID get them. My son is so thankful I convinced him to try them, he had gotten a piece of metal in his eye and rust formed immediately he had the metal removed and the dr used a grinder on the rust, this went on for 3 days and the light hury his eye. We purchased several different glasses but the light still bothered him. So when I found Theraspec I offered to buy them for him, his words "what a relief on my eye, I never thought I would be able to do things again." I purchased both glasses one for day an one for night. As a mother THANK YOU, I have told my family and friends that even if you don't need prescription glasses these are the ones to buy. So THANK YOU AGAIN.
