Lens anti-fogging agent

To be specific, a layer of the anti-fogging agent is sprayed (coated) on the surface of the lens to form a dense, absorbent, ultra-thin, and ultra-transparent biological coating. The coating chelates the droplets inside the coating (chelating means processing the material into a digestible form) to form a continuous and supper transparent chelating coating, which converts the droplets into a transparent micro-glass layer, thus preventing fogging. Spray anti-fogging agent on the surface of the lens, and then wipe evenly with an ordinary lens cloth. It can be used on most lenses. They are easy to use but have relatively short anti-fogging time. During use, the lens should not be wiped or washed. Long time use will affect the lens life.

In general, the frames of the glasses are marked with the width of the frames, the width of the bridge of the nose, and the length of the arm. For example, the inner side of the temple is labeled: 52口 18-135, indicating the lens width of 52mm, the width of the nose bridge of 18mm, and the arm length is 135mm.
