Polarized sunglasses have the widest practicality and can be worn without any burden in almost all scenarios, so many ready-made sunglasses near me have polarization functions.

For example, when driving or fishing, polarized sunglasses are necessary because improving the ability to filter out strong and dazzling light is necessary to ensure driving safety and the reflection of sunlight from the water surface during fishing.

The stress state of sunglasses near me now refers to the distribution of force at various positions of the lens. The processing of the lens itself, as well as the assembly process of the lens and the frame, are prone to stress equalization issues.

Common terms describing the function of sunglasses:

Polarization not only protects against UV rays but also filters out strong light and glare, resulting in clearer vision, but generally lenses have darker colors. Compared to the same model, nonpolarized light has a weaker ability to filter strong and dazzling light.

The refractive index of the lens, for customized lenses with the same degree, the higher the refractive index, the thinner the lens will be. The surface of the coated (mercury) lenses is coated with a light silver film, which reflects light like a mirror.

Of course, there is a type of color-changing lens that can change color with the intensity of ultraviolet rays. Indoor lenses are used for myopia, but when going out, they become sunglasses near me now, which is very convenient.

Progressive color, also known as gradient color, refers to a color that is darker on top and lighter on the bottom and is refracted through the edges and corners of the lens to display the color effect. Progressive colors are the same indoors and outdoors.
