Works perfect. Mote than what i expected. Fast shipping too.

My glasses had a badly damaged AR coating that had severely affected their clarity. I was squinting very hard to read some smaller text. I thought my vision had taken a drastic downswing, in addition to how badly scratched my lenses appeared. I realized the scratches were in the AR coating, which an optician at Wal-Mart's vision center confirmed. Unfortunately they no longer offer AR coating removal services because the chemical they used was very dangerous, and in some cases they had damaged some customers' lenses, so they discontinued the service. Some time later I looked for other solutions, and came across Armour Etch. I knew of the product from reading about its use in glass etching, but did not know it could remove AR coatings without hurting plastic lenses. I purchased some, and while wearing gloves, used a Q-tip to apply it to the inside of my lenses. I applied it and once it started to dry slightly, I applied a little more, especially to the areas where it dried thin. The AR coating on the outside was fairly intact, but the inside was completely trashed. This tells me it was the salt in my sweat over the years. Unfortunately, when I went to rinse them, some of the diluted solution got on the front long enough to start damaging it, so I decided to take both coatings off. It took longer than 5 minutes and more than one application, but the inside coating was removed. The outside layer, being nearly intact, was much tougher to get rid of. After two applications and nearly 30 minutes for it alone, most of the layer was gone. Only a fine bit remained. At this point I could no longer stand to have my glasses off and I was developing a headache so I rinsed them off well again, and put them back on. The difference was 100%. The lenses are now clear once again. And I realized my vision hadn't gotten worse. There is a tiny bit of AR coating left on the front, but I'll be redoing the process again to remove all of it in the near future. This stuff works, but you need to have patience for it. Not everyone is going to have a 1-application, 5-minute perfect result. And you absolutely, without question need to wear chemical-resistant gloves and preferably goggles while using it. The chemicals in this will not result in an immediate burn if it contacts the skin, but will seep into the skin and start burning later. It can do deep-tissue burns all the way down to the bone, and will react with the ions in your skin and bones to keep burning potentially for days. Treatment for the slightest contact is a 15-minute flush with water, and then an immediate visit to an emergency medical facility. So don't think free-handling this stuff unprotected is fine as long as you wash your hands afterwards. It fixed my glasses and saved hundreds of dollars on new lenses I thought I needed. I now no longer have the AR coating which means I'll likely have some glare and reflection issues I'll have to accommodate to, but that's far better than the blurry, foggy scratchy mess I was dealing with before. Until I eventually get an updated prescription they'll do me fine. And in the future if I need to remove a damaged AR coating again, I know what I can use. Now if only we had a way to reverse the process and apply a new AR coating just as easily and simply. Could be a very nice fix, strip the old coating off first, then reapply a new one.

Works beautifully for small glass projects. Easy to apply, and the results are crisp and professional. A fun tool for crafty projects!

Loved this product fast delivery works as it should and good price.
