I have worn Clic glasses for over 15 years. I am on my 3rd pair only because of change in vision. If not for that I would still be wearing my original ones. As a firefighter I used these all the time reading map books, computer screens, and drug boxes for 24 hours, sometimes more. I wore them under my bunker gear and during fire and emergency calls. The durability and scat h resistance is incredible. I have recommended them to over 100 others with great confidence that they will be happy with this product.
Keep up the great product.
