Review on 🔍 Enhance Your Vision with Hydrotac OPTX 20/20 Stick On Magnification Bifocal Lenses - Pack of 2, +2.00 Diopter by Mindi Gefroh

Worse than useless. My online eyewear site offers blue blocking lenses, but they are not available in bifocal lenses. That's why I bought them. They don't disappoint. I followed the instructions carefully. I determined the concavity/convexity, dripped warm water and installed the product. I started an installation cycle, waited 24 hours and then found the lens had fallen off. Then the search begins. I lost three out of four. If I buy a product and follow the instructions strictly, I expect functionality. It just doesn't work. Now I'm stuck with a pair of well made single vision glasses that are useless to me.
