The color of the lens has more than just an aesthetic role. Depending of the color of the lens, sunlight is filtered differently.
In the case of sunglasses, some shades of the lenses add more color to the image, making the colors look much more vivid. Others fade the colors. Some reduce the brightness more, others reduce it less. In this way, each colored lens offers different benefits.
What is the right color for you? That color that improves the visual depth perception and which significantly reduces eye fatigue, without affecting the ability to see clearly.
