Polarized lenses function:

 Polarized sunglasses can effectively block harmful ultraviolet rays, prevent glare, and allow you to see objects clearly in front of you. The principle of polarized sunglasses can also effectively prevent the glaring bright light from the front, allowing you to see more clearly, see farther, and have no reflection or eye irritation when driving!!!!

Glasses not only provide sun protection in summer but are also essential for driving, hiking, trekking, and outdoor leisure activities. In the fall and winter, they serve as windbreakers and sunshades, adding to the light. Fashionable and personalized glasses are also a striking accessory, making you stand out throughout the year!

Polarized lenses have various functions:
     The visible wavelengths, which are between 380nm and 780nm, are the general sunlight we see during the day, composed of a mixture of red, orange, yellow, green, blue, and purple colors. Ultraviolet light with a wavelength of 380nm is a type of harmful light that is invisible to the naked eye. It can cause conjunctivitis in the eyes and, if exposed to it for a long time, may cause cataracts. Polarized lenses with an efficient filter layer can filter out 99% of ultraviolet light (UVA, UAB, UVC).
     (2) Polarized lenses eliminate glare: Reflected light, strong light, and glare. Reflected light and strong light are everywhere, such as the glare from car windows, water waves, snow, and road surfaces, or the direct sunlight from the sun that interferes with human vision, making it difficult to see objects clearly. General colored sunglasses cannot eliminate these annoying light sources, but polarized lenses can eliminate various types of glare, reflected light, and strong light. The polarized filter in the middle layer of the lens is like a window blind, blocking various chaotic light sources such as reflected light, glare, or direct strong light with fine and dense polarized filters, turning the light into parallel light that enters your eyes.
    （3）Lens Surface Reinforcement: Polarized lenses undergo high-tech surface reinforcement processing, which provides them with a significantly enhanced resistance to wear and scratching compared to standard polarized lenses.
    The difference between ordinary dyed lenses and polarized lenses: General colored glasses available on the market are only dyed to make them darker, and they do not have the ability to block unwanted light such as glare from the sun or reflected light from objects, making it difficult for people to see clearly. Polarized lenses, on the other hand, can eliminate light from various directions and reflected light from objects, allowing only light waves traveling in a single direction to pass through, making the field of vision clearer and making objects appear more naturally, allowing one to see the vibrant nature more clearly.
