Lenses can be divided into anti-reflective protective lenses, polarized lenses, and color-changing lenses according to their functions. Currently, most sunglasses on the eyeglass mart are polarized lenses.

When the sun shines on water, roads, snow, and other places, it will reflect scattered light. To filter out these dazzling lights, a special vertical coating is added to the lens, which is called a polarizing sunglass near me lens. It can effectively suppress strong light and is not easily dazzling even when facing the sun. It is most suitable for outdoor sports, such as driving, skiing, or fishing.

Protective lenses are coated with a thin layer of magnesium fluoride on the surface of the lens to prevent strong light reflection, ensure clear visibility, and prevent interference from strong light. Suitable for outdoor workers, in places with strong sunlight, goggles are made with this type of lens.

Color-changing lenses are more suitable for people with lower degrees and little difference in degree between the two eyes. Most color-changing lenses rely on the intensity of ultraviolet light to mediate the color-changing process. Outside, the lenses automatically adapt to changes in ultraviolet light, quickly changing from transparent to dark lenses; Indoors, the intensity of ultraviolet rays weakens, and the lenses return from dark to transparent.

People with lower degrees and little difference in degree between their eyes can choose color-changing lenses, but how should people with higher degrees choose sunglasses near me now? There are two methods.

Contact lenses, which are familiar to most people, can be freely paired with sunglasses after wearing them. Sunglasse clips and contact lenses may be more suitable for girls, while clips are suitable for boys or people who don't like to wear contact lenses. Please choose a flat sunglasses clip.
