Lens
The color of the lens can vary depending on style, fashion, and purpose, but for general use, red, grey, yellow, or brown are recommended to avoid or minimize color distortion, which could affect safety when, for instance, driving a car or a school bus.
• Gray and green lenses are considered neutral because they maintain true colors.
• Brown lenses cause some color distortion, but also increase contrast.
