First, it should have UV and filtration part of the short wavelength light (such as Blu-ray) capabilities.
Secondly, should have an appropriate visible light transmission to control the outside world into the eyes of the intensity of sunlight (the regular optical shop with specialized testing transmittance spectroscopy), we must pay attention to this point.
Third, the right sunglasses should try to avoid the interference of the human eye color perception, different color lenses can produce different results.
Green lenses: reduce the level of visible light eyes, and does not affect visual clarity.
Grey lenses: provide the best perception of color vision, an expert recommended type.
Yellow lenses: to enhance the contrast in the fog, it is recommended not to wear while driving (traffic lights can cause feelings of confusion)
Brown lenses: the general increase in sunlight contrast ratio.
Orange lenses: the case of low illumination to provide maximum contrast eye, and effective filtration Blu-ray.

UV resistance is only related with the lens materials.
