Photochromic lenses are a popular choice for eyewear due to their ability to adapt to changing light conditions. But did you know that there are different types of photochromic lenses available on the market? Let's dive into the various options and how they work.
What are the different types of photochromic lenses?
1. Transitions Signature: These lenses are the most well-known and widely used photochromic lenses. They darken when exposed to UV light and fade back to clear when indoors.
2. Transitions XTRActive: These lenses are designed for those who spend a lot of time outdoors. They not only darken in UV light but also behind the windshield of a car.
3. Transitions Vantage: These lenses not only darken in UV light but also have polarized technology to reduce glare.
4. Transitions DriveWear: These lenses are specifically designed for driving, as they not only darken in UV light but also behind the windshield and have polarized technology.
How do photochromic lenses work?
Photochromic lenses contain molecules that undergo a chemical reaction when exposed to UV light, causing them to darken. When the UV light is no longer present, the molecules return to their original state, causing the lenses to lighten. This process is reversible and occurs automatically.
When choosing photochromic lenses, it's essential to consider your lifestyle and the environments you will be in. Whether you're indoors, outdoors, or driving, there is a type of photochromic lens that can meet your needs.
