When to choose color-changing lens sunglasses?
People who do frequently indoor, outdoor activities can choose. Because the discolored lens will change under different light intensities, the color of the lenses is light in the room because the light intensity is not high, and the light transmittance of the lenses is enhanced. When the intensity of outdoor light is high, the color of the lenses becomes darker and the shading ability of the lenses is enhanced.
When to choose polarized lens sunglasses?
Often polarized lens sunglasses can be chosen by people who like outdoor activities such as drivers, fishing enthusiasts. Polarized lenses eliminate glare from the road, lights, and water, leaving things clear and unobtrusive. Glare is the polarization of light reflected off an object's surface. As a result, glare will increase brightness and decrease color saturation, make the outline of objects blurring, and fatigue and dizziness will occur to the eyes over time. Polarized lenses can not only eliminate interference but also improve the ability to see things. At the same time, the frame material and style design are relatively light, suitable for sportswear.(https://www.koalaeye.com/collections/polarized-sunglasses)
