Frames: Frame material and style is a matter of personal preference.

Lenses: First and foremost, the sunglasses should offer 100% UV protection. There can be a lot of glare reflecting off the road therefore polarized lenses are recommended since they absorb 98% of glare. With the removal of the sun's glare, objects become more distinct and are seen in their true colors. Another option is a photochromatic lens, which will lighten or darken according to the amount of light, a useful feature when driving at different times of day. The lens color can affect how you see the road. For example, a brown based lens will provide the best contrast while a gray lens allows true perception with the least color distortion. Though driving glasses are available in glass or polycarbonate, we recommend polycarbonate lenses because of their impact resistance and durability.
