Wearing eyeglasses online cheap for a day of shopping, the clear and clean glasses were covered with a layer of dust, and while my feet were tired, my eyes couldn't see clearly. The dust adsorbed onto the lens not only affects vision but is also particularly difficult to clean.

The dust-proof film for lenses is similar in principle to a waterproof film, which makes the molecular structure on the surface of the lens more dense and can effectively eliminate the accumulated static electricity on the surface of the lens, reducing the adsorption of dust on the surface of the cheapest eyeglasses lens.

There are always people who like to take off their glasses and casually put them away, or throw glasses without protective boxes, keys, and coins into their bags. Doing so can make the lenses very fragile, with scratches on the surface of the lenses and blurred vision. At this point, wear-resistant film protection is needed.

To improve the wear resistance of lenses, it is necessary to use a hardening solution containing organic matrix and inorganic ultrafine particles to deposit a hard film on the surface of the lens, so that the surface of the lens has both toughness and hardness. This layer of film is a wear-resistant film that can reduce scratch damage.

To make it safely accompany you, just do:

① Take off your glasses put them in a pressure-resistant mirror box, and keep them out of reach of children.

② Dilute the glasses with cold water and neutral detergent. It is not recommended to use any other liquid to wash the glasses.

③ When encountering high-temperature scenes (especially bathing or cooking), try to wear old glasses to ensure that the lenses of new glasses are intact.
