STICKTITE LENS Medium 32 mm - Stick-on bifocal lenses - Instantly convert sunglasses into magnified, bifocal sunglasses.

These are working great so far. Easy to apply and move into position, and work great on my Wiley X Valor Polarized Sunglasses. I can now see my Android Auto much better.I just applied so as long as they stay on, I will keep them at 5 Stars!

I was surprised that these stuck on so well and actually worked. My problem is that I prefer the entire lens to be the same so I don’t use them often. They are very clear, stick well and work great if you don’t mind bifocals.

This is now my third set if StickTite lenses. This 32mm size is a big success for adding bifocal capability to my driving glasses.There is a simple formula for calculating the diopter you need for a near distance, given your far distance prescription. Don't trust me, look it up.1/D = fWhere D is the focal distance (from my eye) in meters and f is the ADJUSTMENT to my lens power in Diopters. So for example, if I my vehicle dashboard is 0.8 meters from my face, we have:1/D = 1/0.8 = DD = 1.25 = +1.25So you could apply a StickTite lens strength of +1.25 to your distance glasses (clear or sun).The first time I tried these they didn't stick as well as I hoped, perhaps because of a coating on the lens. Nevertheless, they have never come off and continue to work fine. I've had better results with subsequent applications. Do watch their video and follow the instructions. Some good news: you can take them off and try again.If you buy all your glasses from an optician you may be able to get bifocals that you like. But I like to buy glasses online. It's great for single-vision but with bifocals they never seem to get the position and size right. The StickTite lenses allow me to put them where I want them.

These were a total waste of money: They don’t apply well, they make near vs. far vision awkward and they don’t stay in place. They went straight on the trash bin on the boat.

Fuzzy areas. While they do work, the view has some fuzzy areas that make them a tad annoying. They do apply easy enough, but I removed them, cleaned and reapplied, but still barely usable.

The 32mm are good for me because they are small enough that I dont notice the lens while skiing. I can read my phone now without the need for bifocals under my goggles or swapping with reading glasses on a lift. Its so convenient. I work in a ski resort and so far they have stayed on for weeks of hard skiing.

A little challenging to put on but doable.

They work well and are easy to put on. Just don't know how long they'll last. Only have had them 2 weeks or I'd give them a 5. Got them for sunglasses so I can see to tie on the lures and flies for fishing.
