They also have a blue light blocking function that cuts blue light by an average of 35%. These are stylish and cool color-changing sunglasses in large sizes for men. The temple ends are made of rubber material to improve comfort and fit. In the car, the color is medium (about 40-50% concentration) *Does not darken completely Car windshields are UV-resistant.

Dark color (80-90% concentration) outdoors Regular photochromic lenses are easily affected by temperature changes, and do not darken easily when the temperature is high.
