Hydrotac Stick-on Bifocal Lenses - +3.00 Diopter, Adult, Unisex, Rimless, Plastic, Hydro-Phobic Coating, 3 Diopters

When it sticks it very good but I find it don’t stay on my glasses very long

I love these! I’ve bought several sets and use them on my non-prescription sunglasses. They work great and let me turn regular sunglasses into readers without having to buy prescription sunglasses. The best part is that I don’t notice any distortion in my vision when using them. They can be a little tricky to apply at first, and it may take a few tries to get the placement just right. I use just a drop of water to apply them, and once they’re positioned correctly, they stay in place and don’t move around. They’ve worked really well for me, and I’ll definitely continue buying them!

Muy util para poder leer con lentes obscuros

I have used these before but just purchased this set for wraparound sunglasses I use in my car. I recently had cataract surgery on both eyes that corrected my distance vision. The only problem with that is I now absolutely need reading glasses to see my dash instruments and GPS screen. Bifocal sunglasses would cost me a few hundred bucks. My solution, a pair of $25 wraparound sunglasses and a pair of these OPTX 20/20 stick on lenses for my diopter. Caution though, when I say stick on, they don't really stick on. Clean the lenses of your glasses or sunglasses thoroughly, dry them off and then just put a couple of drops of water at the bottom of the lens where you want to put the OPTX lens. Then place the lens over the drops of water. Before you press them permanently in place, put the glasses on and make sure you have the OPTX lenses in the right position to read clearly through both eyes. I found I had to move mine a little closer to the inside of the sunglass lenses for best vision. Once you have them in the right position, take a tissue paper and gently press them into position absorbing extra water. Make sure they are uniform with no air bubbles by pressing them uniformly into position. Then leave the glasses for a while until everything is dry. Check them every once in a while to ensure they are starting to peel off but the hold very well when installed properly. If you need to remove them to move them to new glasses, gently pry them up from one edge until they come loose and then reinstall them on the new glasses the same way. If the OPTX lenses are too large for your glasses they can be carefully cut down at the straight edge with a sharp pair of scissors.
