[OWNDAYS] Introducing photochromic lenses that change color depending on the amount of UV rays!

Photochromic lenses are lenses that change color in response to the amount of UV rays. They can be used as both glasses and sunglasses, and the lens color darkens outdoors when UV rays are strong, and changes to a clear color indoors when UV rays are weak.
This is also recommended for those who find it troublesome to take off and put on glasses and sunglasses when traveling or outdoors!
Regarding color change, it takes a little longer to lighten than it does to darken.
In addition, the color intensity changes not only depending on the brightness of the weather but also on the amount of UV rays, so the color of the lenses will change even on cloudy days.
Please try it out at the store!
