What are Polarized Sunglasses?

    Polarized sunglasses are a kind of sunglasses that not only can block UV Rays but also can block glare.

What are Polarized Sunglasses

How do polarized sunglasses work?

    The polarized sunglasses are made according to the polarization principle of light. When the vibration plane of the light and the polarization axis are parallel, the polarized light filter can transmit the polarized light (The theory is similar to that of blinds). In addition to preventing UV rays and reducing light intensity, polarized glasses can filter out glare. The light in a specific direction enters the eye through the light transmission axis to form a visual image, which can effectively suppress the interference of outdoor cluttered light sources and is not dazzling when looking directly at the sun.

Polarized sunglasses VS ordinary sunglasses

Normal sunglasses

    Generally, sunglasses lenses are mainly tinted lenses, which block sunlight and ultraviolet rays by reducing light transmittance. It cannot filter light, so it can only reduce the intensity of glare, ultraviolet light, etc., and cannot completely block these harmful rays.

Polarized sunglasses

    Polarized lenses can effectively block sunlight and ultraviolet rays. There is a polarized film layer, which can block light in a specific direction to achieve anti-glare. Polarized lenses have polarized properties, so they can completely block the dazzling glare caused by various factors such as scattering, refraction, and reflection. At the same time, it can completely block UV rays that are harmful to human eyes. Therefore, when people are under intense light for a long time, the eyes are not easy to get tired, achieve the function of protecting eyes and can see things more clearly and three-dimensionally.

How to distinguish polarized sunglasses?

     There is an easy to distinguish polarized sunglasses. Stack two polarized lenses vertically. If they are opaque, it means that they are polarized lenses. The design of polarized lenses only allows parallel light to pass through the lenses, so when the two lenses are stacked vertically, most of the light will be blocked.

    Eyekeeper provides fashion and high-quality polarized sunglasses. If you need polarized sunglasses, I am sure you will pick the one you like!
