In addition, they cut blue light by an average of approximately 35%. These are stylish blue light blocking sunglasses with a half-rim design using metal material. They are cool, large-sized, and stylish color-changing sunglasses in gunmetal or silver, perfect for the edgy, slightly rebellious man.

Outdoors, the lenses will have a dark tint (80-90% density). Ordinary photochromic lenses are easily affected by temperature changes, and will not darken as easily in high temperatures. ARTtypeEX lenses have a much higher tint density compared to ordinary photochromic lenses, and will perform well even in high-temperature environments.
