Protection: Eyeglass bags provide protection from scratches, dust, and other debris that can damage lenses. Portability: Eyeglass bags are small and lightweight, making them easy to carry around in a purse, backpack, or pocket.

Since cotton cloths are inferior cleaning materials, you have to rely on chemicals to do most of the cleaning. We’ve become so accustomed to this way of cleaning that it’s hard to imagine doing it any other way. But there is a better way — with microfiber! Using a microfiber cloth to clean surfaces only requires a little bit of warm water. You can use mild cleaning chemicals if you want, but they really aren’t necessary.

Glass lenses are more resistant to scratching than polycarbonate lenses, but whether your lenses are plastic or glass, it’s important to store your sunglasses in a case. Don’t just drop sunglasses in a purse, laptop or messenger bag, or shove them in your pocket. Your sunglasses are likely to get scratched by keys, pens or rough denim fabric.

​Microfiber cloths are made of polyester and nylon, as opposed to cotton, like most cleaning cloths are. The key advantage here is that the fibers are split to over 100 times smaller than a human hair, creating a larger volume of fibers touching a surface area and making microfiber significantly more absorbent. Microfiber also has a natural static charge built up that attracts dust particles and forces them to cling to the cloth.
