Review on 🔍 Enhance Vision Instantly: Hydrotac Stick-on Bifocal Lenses +3.00 Diopter (OPTX 20/20) by Danny Crowder

It was a pleasure to use! I should have bought a smaller magnification. They easily installed on the inside of my "cheap" glass lens sunglasses. It took a few tries to find the sweet spot, but they stayed there all summer. So far, so good. It's nice that you don't have to keep changing glasses (except in some cases when progressive lenses deteriorate). I would definitely order more. I have a set on my snorkel mask. (Actually they were made by "Dive-Optics"). Makes it much easier to see objects in the water that you normally wouldn't be able to focus on underwater without glasses. Next time I'll use a magnification of 2.50. They work. Easy to use. If necessary, you can remove other glasses and stick them again. No sticky materials required - just water!
