So choosing sunglasses is not the fact that the darker the lens color, the better. On the other hand, wearing glasses of lenses that are too dark on the wrong occasions can be dangerous. For example, when driving in summer, the sunlight is very strong, and wearing dark sunglasses when driving is easy to filter out light-colored objects, affecting the judgment of the distance between cars.
