The sunglasses near me we usually wear look the same, but there are differences. One difference is polarization and nonpolarization.

Color-changing lenses are transparent indoors and change color when exposed to ultraviolet light outdoors. The stronger the ultraviolet light, the darker the color. They can be used as sunglasses outdoors. The main function of color-changing lenses is to adjust the transparency of the lenses through color changes, allowing the human eye to adapt to changes in ambient light, reduce visual fatigue, and protect the eyes.

At present, the variable colors include deep space gray, cherry blossom pink, Roland purple, ocean blue, mocha tea, coral orange, cocoa brown, and round tortoiseshell glasses yellow. Both nearsightedness and flat light can be worn. The interior of the car is indoor and does not change color; The thicker the lens, the heavier the background color, the darker the color after discoloration, and the slower the relative color recovery speed.

Stained lenses are mainly used as sunglasses or decorative lenses. Can dye lenses of any color, with different UV protection coefficients depending on hue, brightness, and purity.

Nonpolarized sunglasses near me now only use the function of reducing glare and the intensity of ultraviolet light to minimize eye damage, but cannot completely block these harmful lights.

Polarized sunglasses, due to their polarizing properties, can completely block glare caused by various factors such as scattering, bending, and reflection, as well as completely block harmful ultraviolet rays to human eyes. Filtering out these stray lights, it is also very soft and comfortable to see things in strong sunlight.

When going out for outdoor activities, traveling, or driving, it is best to wear polarized sunglasses. The light is relatively soft, comfortable to look at, and can also prevent ultraviolet rays, strong light, and various miscellaneous lights.
