Review on 👓 Pack of 2 Hydrotac OPTX 20/20 Stick On Reusable Bifocal Lenses, +1.75 Diopter for Enhanced Vision by Priscilla Roque

I have bought them before with good results. However, the last purchase turned out to be a waste of money. The plastic just won't stick to the glasses even when I use the same identical model of glasses that I used previously with these stickers. I even tried re-wetting the plastic by soaking it for a few days in case it dries out in the packaging. But no matter what I did, the results were the same - the plastic was separating from the glass, leaving large pockets of air. In the end I had to give up and throw them away. Absolute waste of time and money.
