Review on 👓 NEOPTX Hydrotac Stick-on Bifocal Lenses - OPTX 20/20, +2.00 Diopter: Enhance Your Vision by Chelsea Hunter

These stickers are not cheap. They may work well on standard glasses, but I've tried them on goggle-like sports glasses that have more curvature than these lenses. There's no way to adjust them for more curvature and they'll pop right out. It is impossible to stick them to the glasses only by the force of water adhesion. It's a good idea, but definitely not recommended with limited use and a fairly high price. Finally, the DropCrate LLC store DOES NOT accept returns. So buyers beware!
