Poor choice of frame and lenses can seriously impact safety. Some sunglasses reduce contrast, distort color, and impair visibility, especially in poor lighting conditions.
It is recommended to use models with UV-400 or 100% UV protection marking, which block ultraviolet radiation. The appropriate level of light transmission is category 2 and 3 (8–43%). Category 4 glasses, which transmit less than 8% of light, are prohibited for driving in EU countries. Their use can lead to a fine for obstructed view.
The color of the lenses also matters. The safest are considered to be gray and brown glasses, as they do not distort the color of traffic signals. Yellow, green, and blue lenses can impair contrast and hinder orientation in twilight or tunnels.
Photochromic glasses, popular in everyday life, often do not work properly in a car: ultraviolet is blocked by the windshield, and the lenses do not darken. Glasses with anti-glare coating and a sturdy, lightweight frame that does not obstruct the view or slip are best. Large lenses with side protection and frames made of impact-resistant nylon are the most suitable.
