[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 ultraviolet light.
The key feature is that it can be used as both eyeglasses and sunglasses; the lens color darkens in strong UV light outdoors and changes to a nearly clear color indoors where UV light is weaker.
This is highly recommended for those who find it troublesome to constantly switch between glasses and sunglasses while traveling or engaging in outdoor activities!
Regarding color changes, it takes slightly longer for the color to lighten than for it to darken.
Furthermore, the intensity of the color changes not only depending on the brightness of the weather but also on the amount of ultraviolet light, so the lens color will change even on cloudy days.
