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.

Used to add shooting bifocal and worked well.

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.

Greatest idea ever!
I wish I had invented this! What a savings, as opposed to the cost of having prescription bifocals added to your favorite sunglasses! Love them and own 4 pair!

How did I not find these sooner?
As a pilot, I have my favorite sunglasses that I wear in the plane. Getting them bifocal was cost prohibitive. Switching back and forth to reading glasses was tedious. This product solved it! Easy to install and position, I'm no longer changing glasses while flying! The magnification is perfect and clear. Recommended!

transformed my sunglasses
I applied these Hydrotac lenses to an expensive pair of sunglasses I received as a gift. They are great! I can read very well and the applied lenses don't block my view when I'm not reading. I did have to cut them down a little, using the instructions provided. Great purchase!
