I am very pleased with this product. A very cost effective approach to prescription sun glasses . I now have 3 pairs !

Converted two pair of costly polarized prescription sunglasses. Installed per instructions, making certain that the lenses were scrupulously clean. A pair of tweezers were helpful in getting them positioned correctly; I set them up so that the line was at my car dashboard level, so I can see outside and the instrument panel equally well. They work better than I expected. Highly recommended, would buy again.

hard to keep in place
I finally got them to stay on the glasses but they came off and now are lost.
Staff Response: Always caused by oil film residue left on lenses. Use a dab of dishwashing liquid and rinse to remove any oils from the surface of the lenses before re-applying.

Working good on sunglasses. Tried to trim one side with a very sharp razor blade while lying on hard flat surface & newspaper, and found more difficult than expected from directions. I marked bottom edge with a sharp pointed sharpie and cut inside edge with sharp strong pair of scissors and it worked much better. Turned first one upside down on other and used it as outline. Took me a couple of tries to stick on backside of glasses to get bubbles out.Works great to read instrument panel while driving and reading basics with sun glasses. Much better than several hundred dollars for poor sunglasses with just Rx for reading.

While the magnification received was correct I cannot see thru them. I have several other pairs of 1.5 reading glasses which perform well, these are not working for me at all.
