What are photochromic lenses?
Photochromic lenses, also known as light-adaptive lenses, darken when exposed to light (UV). They are not only convenient but also eliminate the need for multiple pairs of eyeglass frames. These lenses are perfect for you if you need to go out and inside the buildings on a daily basis. They also block UV rays, ensuring that your eyes are always protected from harmful rays.
The lens technology is accomplished by embedding molecules of photosensitive compounds into the prescription lens material like silver halide. The molecules undergo a chemical reaction whenever they are exposed to ultraviolet rays that result in darker lens color.
Photochromic lenses are available in gray, brown, and green colors. They can be made to fit a wide range of eyeglass frames and prescriptions.
One of the more famous brands of photochromic glasses is called “Transitions” lenses. As with the Brands Kleenex and Frigidaire, many people mistakenly refer to the technology by the brand name.
Pros and Cons of photochromic lenses
Photochromic lenses are a great option for people who need prescription eyewear and have to spend time in different light conditions. Here are some pros and cons of using photochromic lenses:
- Convenience: photochromic lenses eliminate the need to carry around an extra pair of eyeglass frames and switch between different pairs of eyeglasses.
- Protection: photochromic lenses help guerd your eyes from UV rays. They are designed to darken when exposed to UV rays, which helps to reduce glare and eye strain.
- Comfort: photochromic lenses offer a comfortable and seamless transition between indoor and outdoor environments. They allow you to see clearly and comfortably in any lighting condition.
- Cost: photochromic lenses tend to be more expensive than regular prescription lenses. However, the cost may be worth it if you value convenience and eye protection.
