Great product!
I was so happy to come across this product, have tons of sunglasses but can't read anything with them on and always had to switch to my glasses while in the car or walking, etc... But then I found these so easy to install and work great. I put them on my sunglasses and now am able to read my texts, watch, etc while out and about with out switching to my reading glasses. Will definitely be purchasing more.
