I've been using these glasses for over 2 years. They're really great — comfortable and don't fog up. I recommend them!
The temple attachments could be a little stronger, but I actually find it convenient — I have two pairs and mix and match the colors as I like.
Photochromic lenses :The lenses change color based on the amount of light, providing optimal visibility in different lighting conditions.
TR-90 frame material :The frame is made of a durable and lightweight material that can withstand impact and extreme temperatures.
Polycarbonate lenses :The lenses are made of a strong and shatter-resistant material, ensuring eye protection during cycling and other outdoor sports.
Photochromic lenses have UV400 function and will change color under direct sunlight. Discoloration occurs in about 1 minute in winter and about 40 seconds in summer. Speed depends on sunlight and UV intensity! (If the UV intensity and temperature are low, the color change rate will be slower.) The color change rate is related to the UV intensity and temperature.
Avoid contact with perfumes, insecticides and other items containing chemical ingredients, so as to avoid chemical corrosion on glasses lenses and frames, and better protect your glasses.
