Review on Hydrotac OPTX 20/20 Stick On Magnification Bifocal Lenses - Reusable +2.50 Diopter (Pack of 2) by Kathy Sabo

I needed reading glasses after my cataract surgery. He already had three plain Maui Jim sunglasses and wouldn't buy all of the new Maui Jims. Found these lenses by accident and thought I'd give them a try for the price. They are easy to install and the visibility is better than expected. The main issue was that they were a bit too big, but the instructions said they could be cropped. I positioned the lenses where I wanted them, used a super fine marker to mark the area that was sticking out from under the lens, then slowly trimmed them off with a sharp small pair of scissors. Worked like a charm and didn't affect vision at all. For example, the ability to toggle the power of the lens for reading, driving, etc. In an ideal world, they could be a bit thinner, but that's not such a big issue after they've been trimmed. Hopefully they will continue to sell many of these for a long time to be available in the future if needed.
