Confusing brand labeling but they work
I have prescription lenses with a treatment for antifog cloths. The retailer charges $12.95 per cloth and shipping and handling, so I figured I'd give these a try since they're $4.99/6 as of this writing. When I received my order, it was packaged in a small box and each cloth is in a Mingdai brand resealable packet. This isn't what was advertised, but they work so I'm going to keep them. I saw reviews saying these don't work, but they're working for me. The trick is you have to follow the instructions and exhale onto your glasses so there's some moisture. Then wipe the cloth around a bit and the antifog will activate. It's not going to give you 100% antifog, but works well enough when you're transitioning from the cold outside into a grocery store, or similar (i.e. you might get a little fog, but can see well enough to not need to wipe the condensation away).<br /><br />So while the brand labeling is off, these are performing like the retail brand cloths at a fraction of the price, so I'm happy with my purchase.
