What is hard coating on lenses?
Lenses are mainly added in two kinds of film: anti-reflection film and hard film (and some manufacturers produce anti-fogging film and mirror film, but not common). The anti-reflective film is mainly by coating the front surface of the lens with multiple layers of transparent materials with different refractive index and thickness to reduce the excess reflected light on the surface of the lens, by using the principle of light interference. The film can be applied to both glass and resin lenses. The way of hard film plating is usually a soaking process. After many times of soaking and cleaning, soaking in an organic solution containing ultrafine silicon element for a certain time, and then keeping it at a certain temperature for 4-5 hours, the fixed polymerization process of the film has been completed. The surface wear resistance of CR-39 coating can be increased by 2-4 pH, which is similar to the hardness of optical glass lenses.
Each type of store has its own characteristics.
Nowadays, the optical stores in the market can be roughly divided into professional optometry and optical matching stores, fast fashion stores, brand flagship stores, and stores in shopping malls.

The size of fast fashion optical stores is usually not large, so they will use an open showcase design. The color collocation should be able to catch the attention of consumers, to attract customers to make self-service selection and experience.
