I can finally read my computer.
Rode in to work today with my new stick on bifocals on my sunglasses. What a difference, why did I wait so long?.
The first set came with one lens that would not stick. I called "Safteyglassesusa", they apologized and sent out a replacement, telling me to keep the bad pair as a spare. Now thats what I call customer service!
I bought a pair and was also very pleased. Very inexpensive and they work. One of mine came off but i reattached it (water) and it has stayed on. Can read a ride guide or map and the computer now without changing glasses.
Love these things.
Found out about them via this forum about 8 months ago.
So far I've bought and attached 3 sets to different sunglasses. (cheapest price I've seen is approx $10 at Amazon.)
