Review on GMS Optical® Premium Silicone Adhesive by Obhed Leblanc

***update*** After using the product for over a week I understand why people say it doesn't stick. After about a week they start to slip. But I still feel that the pros outweigh this con. I will only change them every few weeks. $6 every 2 months for a replacement pack is fine with me. I could probably use super glue to hold them in place, but I still wouldn't damage my frames. *** I assume people who say glue doesn't stick don't know how to read instructions. You must clean the surface of the frame with alcohol to remove oils before applying! I've even been able to take mine off and reposition it once and they're still holding up well. I've been wearing them for a week now with no problems. They made my plastic frames perfect for my narrow bridge! They really take some getting used to because yes they do stick to your nose a bit but that's actually a plus not a minus as they prevent your glasses from slipping! do they stay forever Probably no! But they come in packs of 10 and I personally don't want to use the same ones forever because I know they get dirty with makeup and other face oils so you must WANT to change them! Try it!
