The eyewear brand Zoff has released "visible light photochromic lenses" that react not only to ultraviolet light but also Zoff visible light, changing color even when driving in daylight.
 
Conventional photochromic lenses change color depending on the amount of UV rays, but the new visible light photochromic lenses react to visible light as well as UV rays, so they naturally change color according to brightness not only outdoors but also in a car during the day, reducing glare. They are particularly effective in situations where glare is more likely to be felt, such as in a car during the day or near a window, where UV rays are less likely to reach.

It is capable of "gradation support," which means that the color changes gradually depending on the intensity of light, making it suitable for the following usage scenarios.
•When in a car where strong light shines through the windshield, the lenses naturally color so as not to obstruct your view, even in tunnels.
• Protect your eyes with a subtle tint and natural tone when sitting by a window in an office or cafe during the day.

This means that instead of the traditional binary choice of "outdoors or indoors," you can now take measures against glare that are tailored to the changing lighting environment in your daily life. This product also blocks 99% of UV rays, so it's recommended not only for glare protection but also for UV protection.
