they turn darker in sunlight
Photochromic lenses adjust their tint based on the light getting darker in the sun and clearing up inside. They're perfect if you want one pair of glasses that works as both sunglasses and regular glasses. You can find more details at Eyeglass Direct.
The technical term for a lens that has a variable tint is aphotochromic lens (also called photochromatic if you are in America). One of the most well known and commonly sold brands of photochromic lenses are "TRANSITIONS". Photochromic lenses get darker when they are exposed to ultra-violet light, not when you are indoors in a brightly lit room with artificial lights. Photochromic lenses are best suited to slightly cooler climates as they react much quicker and will go darker when they're cold compared to using them in a very hot climate.
Photochromic lenses are made by adding special light-sensitive molecules to the lens. These molecules darken in sunlight and go clear again when indoors or out of UV light. The process uses a mix of materials to make this happen.
Photochromic sunglasses darken when you’re outside in the sun and clear up when you’re indoors, so you don’t need to switch between glasses and sunglasses. Eyeglass Direct has plenty of stylish options with these lenses for both comfort and convenience.
Those are called photochromic lenses. They contain special molecules that react to ultraviolet light, causing the lenses to darken in brightness and clear up when UV exposure decreases.
The advantages of having photochromic lens on your sunglasses are not only convenient (ability to go from outdoors to indoors with changing eyewear) but they enhance vision of patients with various ocular pathologies (diseases) and those who have light to moderate sensivity to light.
Photochromic polymers are used in things like glasses, car windows, and smart windows because they change color or darken when exposed to sunlight. You’ll also find them in UV sensors, cosmetics, and security features for added functionality.
