Polarized Wellington Square Shape Polarized Fashion UV for Men and Women [Megane Style] Sunglasses, Non-Prescription, Frame, Lightweight, Memory,

While direct sunlight can be reduced by wearing dark sunglasses, light reflected from surfaces such as roads, buildings, and water surfaces and entering the eyes is scattered, creating complex diffuse reflections that cannot be dealt with by ordinary sunglass lenses. Polarized lenses, however, use a polarizing filter to adjust the direction of light travel, eliminating the noise from diffusely reflected light that ordinary sunglass lenses cannot handle. The frame is made of TR-90, a safe and lightweight resin also in baby bottles and medical catheters. TR-90 is highly elastic and resilient, making it strong and resistant to deformation. It's a shape-memory frame that provides a comfortable fit that won't cause pain even when worn for long periods of time.
