Photochromic lenses are common in glasses, they stay transparent indoor, but get darken when exposed to sunlight. How does it work ?
Photochromic lenses contain molecules that are sensitive to ultraviolet (UV) light. When exposed to UV light, these molecules undergo a chemical reaction that causes them to darken. This darkening blocks out harmful UV rays and reduces glare.
Yes, photochromic lenses and transition lenses are the same. They both refer to lenses that darken when exposed to UV light and lighten when removed from UV light.
Photochromic lenses are designed to work in a wide range of lighting conditions, from bright sunlight to indoor lighting. However, they may not darken as much in very hot or cold temperatures.
The time it takes for photochromic lenses to change color depends on the amount of UV light present. In bright sunlight, the lenses can darken in as little as 30 seconds, while in low light conditions, it may take a few minutes.
Yes, photochromic lenses can be used as sunglasses as they provide UV protection and reduce glare. However, they may not darken as much as traditional sunglasses, so they may not be suitable for very bright conditions.
