Review on 👓 Optx 20/20 Stick-On Bifocals, Plus 1.75 by Jessica Gibson

I ordered 3 sets +175. I opened and installed 2 of 3. Installation was quick and easy, but here are 3 tips: 1) Don't ignore the instructions that state your lenses must be clean, dust and oil free. 2) Plan your placement before you start. You only have about 5 seconds before the connection becomes too strong to adjust the position. 3) Be willing to hold onto them for a minute or more. They are strongly curved and very stiff. If you let go of them before they fully adhere, they will detach from the glass and trap air, rendering them unusable. The first set I used came out great and good to read. There were a few problems in the second set. One lens had a manufacturing defect - a dimple on the right edge that I felt with my finger. I installed it anyway just to see if I could get it working. He couldn't, and as expected, there is an air pocket under the dimple. The other lens in this set was so stiff and curved that the entire right side of the lens would not stick together no matter how long I left it in place, making it unusable. I still have the third set and will try to remove the damaged one. and replace them, hoping the second set was an accident.
