From the perspective of the lens manufacturing process, mirror sunglass near me cannot be considered as a separate type, but rather a vacuum coating method.

However, due to the strong appearance characteristics of mirrored sunglasses, they will be explained as a category here. Mirror coating can be used on dyed (colored), polarized, and discolored sunglasses as mentioned earlier. The materials used are similar to AR anti-reflective coating - coating materials with different refractive indices are heated by an electron gun in a vacuum furnace, and the coating material evaporates at high temperatures to deposit a certain thickness on the surface of the sunglass near me lens.

Unlike AR coating, mirror coating significantly increases reflectivity by changing the thickness of the film, thereby achieving a mirror-reflection effect.

Mirror coating is usually combined with dyed or polarized sunglass near me and applied to the outer surface (convex surface) of the lens. The reduced transmittance makes it very suitable for various water, snow, and high-altitude environments and also provides users with a cool-wearing experience.

With a certain design of mirror facial mask layer, the darker the color of the lens base, the stronger the mirror effect. By adjusting the membrane design, different colors can be reflected as needed to meet personalized needs. In addition, mirror coating can also be applied to large-area facial protection, such as on ski goggles.

So, which one is better for choosing a polarizer? From the perspective of polarization efficiency, there is no significant difference (efficiency95% is appropriate), but the biggest difference lies in functionality. Occasionally using a polarizing film (clamp), only injection or casting molding can be selected for polarizing with degree and casting molding (with high refractive index) is recommended for higher degree polarizing
