[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.
The key point is that the lens color darkens outdoors when UV rays are strong, and becomes clear indoors when UV rays are weak.
It will change to a similar color.
Highly recommended for those who find it difficult to put on and take off 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 depending on not only the brightness of the weather but also the amount of UV rays, so even on cloudy days, the color of the lenses changes.
There is a change in color.
Be sure to try it out at the store!
