Bifocal Buddy Stick On Bifocal Lenses - Magnifying Reading Glasses Bifocals for Sunglasses, Safety Goggles, Diving Eyewear

I put these in my scuba mask. I was able to easily see my guages. I had no problem attaching them & they stayed in place, even with rinsing my mask multiple times.

These are pretty nice but I seem to have one that is labeled “15d” and the other “25d” and I’m struggling to get visual clarity. I have another pair and they have matching labels and are much better.Edit to add: I've returned them. I have another par another set of sunglasses and they are great, and made me realize my original pair were mis-matched. Updating the rating, was 2, now 4.

Easy to install but visual quality is lacking but for the price it is not going to get much better.

Is adequate for what these are, bifocal decals.

Gard to apply. If you need to reposition them, good luck.The surface is not flat, but wavy, disrupts vision. There is a number imprinted on them that also interferes.They stay sticky, great for attracting dust etc.Quite thick, giving a harsh bifocal line.Cannot recommend, will not buy again.One star is giving them too much credit.

These are great if you have a nice pair of sunglasses and you want to be able to read without the expense of prescription lenses. They come in a nice, small plastic carrying case that fits easily in a pocket or purse. Very convenient. Even if you have distance glasses and want a little help with reading, just position the correct strength in your lenses and you're good to go.

Used these to convert polarized sunglasses that I love into readers as well. No longer a need to switch glasses when I want to read something outdoors! They are easy to apply and they do stay in place.

They are the right size and right magnification. But the material is not smooth and is edgy and bubbley upon application so it's not clear enough to look through properly.
