In general, gray lenses absorb infrared light and 98% of ultraviolet light, while yellow or brown lenses filter out large amounts of blue light. “Blue-ray is the most harmful to people's eyes.” Wearing yellow glasses can effectively filter out blue light, which greatly improves visual contrast and sharpness.
