Photochromic Sunglasses are the eyeglasses that gets darken when exposed to the sun. Created by Corning in the late 1960s and popularized by Transitions in the 1990s,these are also sometimes called photochromatic. Lenses in photochromic sunglasses rely on a specific chemical reaction to UV radiation.
What else can I help you with?
Where can you buy Photochromic Paint?
You can purchase photochromic (color changing) paints at most automotive paint stores.

What does Photochromic football visors do?
they turn darker in sunlight
What exactly are photochromic lenses and why should I purchase them?
Photochromic lenses change with the light they get dark in the sun and clear indoors, giving you UV protection and making life easier. if you are looking for photochromic lenses this is the site I usually follow Eyeglass direct
What does the term photochromic mean?
It means changing colour in resonse to light.
What are photochromic sunglasses?
Photochromic Sunglasses are the eyeglasses that gets darken when exposed to the sun. Created by Corning in the late 1960s and popularized by Transitions in the 1990s,these are also sometimes called photochromatic. Lenses in photochromic sunglasses rely on a specific chemical reaction to UV radiation.
What is the stimulus for photochromic material?
The stimulus for photochromic material is light, particularly ultraviolet (UV) light. When exposed to UV light, these materials undergo a reversible chemical change that alters their color or transparency. This property allows photochromic materials to transition between different states in response to varying light conditions, such as darkening in sunlight and returning to their original state in the absence of UV light.
How do you call sunglasses lenses that turns darker in the sun and lighter in the shade?
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.
How is photochromic lens made?
Photochromic lenses are made by incorporating molecules called silver halide crystals into the lens material. These molecules are responsive to ultraviolet light, causing the lenses to darken when exposed to sunlight. The process of making photochromic lenses involves embedding these molecules in the lens material during the manufacturing process.
What is Photochromic polymers used for?
Photochromic polymers are used in various applications such as eyeglasses, clothing, and toys to create products that change color in response to light exposure. This unique characteristic allows for customizable and interactive designs that adapt to different lighting conditions. Additionally, photochromic polymers are utilized in sensors for detecting UV light and can be incorporated into smart materials for novel technological advancements.
What is the properties of photochromic?
Photochromic materials are substances that change their color or transparency in response to light exposure, typically ultraviolet (UV) light. They can transition between a colorless state and a colored state, allowing them to adapt to varying light conditions. This property makes them useful in applications like photochromic lenses in glasses, which darken in sunlight and return to clear indoors. The reversibility of this process is a key characteristic, allowing repeated cycling between states without degradation.
