Hi Clear Stick On Bifocal Lenses Reader Magnifying Adhesive Reading Lens Sticker Sunglasses Safety Glasses Magnifier Add On (Clear, 3.0)

I was able to get them to stay on my glasses using distilled water, but was unable to get all the bubbles out. They do stay put, but the magnification is about like an inexpensive magnifying glass. They were difficult to trim down to the size to fit my Ray-ban sunglasses. Overall, they served their purpose as I can read small print while using the sunglasses, but it's not near the quality of using bifocals.

I use these with my favorite cycling sunglasses. It IS important to thoroughly clean & rinse the lens area before applying. Like any vinyl stick-on, these magnifiers will fall of if there is any residue of grease or cleaner. They're designed to create a bi-focal, but since I use them for cycling in a lean-over position, I placed the stick-ons high up on the lens so I can see detail while riding and they're a huge improvement.

I got 200+ but wanted 175+ which was not available. So they are too strong. I like this product because it is easy to use and just what I need to make my sunglasses readers

Wish there was a guide included for trimming the lenses..

I like these magnifying stickers. Really helps when trying to read in the sun.

These started out ok. Usable with some waves or minor distortion. As time went by over a month they became unusable. I’m meticulous about my glasses and it was the product quality 100% that caused the problem.

They work but for smaller lens it will obscure regular vision. Wish there was a smaller version!

Bought this for my wife, and she’s so satisfied she encouraged me to write this review.Now all of her regular, cycling and running sunglasses have bifocals taking full advantage of the product.
