Review on 👓 Enhance Your Vision with Optx 20/20 Hydrotac Stick-On Bifocal Lenses (+1.25) by Mike Bray

FYI later. Apparently they need a flat surface and prescription glasses are "layered" for some corrections. My. So you won't stay at all. I tried and read the instructions. nope I wanted to add more magnification to a pair to be able to work very close to small subjects. If you want to do that, buy some patches from the dollar store, look at your prescription card and order 1.25+ whatever your rx for bifocals is my suggestion. Otherwise buy some readers which are not suitable for me as I have astigmatism.
