If you’re fascinated by the idea of glasses that change color, you’re not alone. These innovative eyewear options are becoming increasingly popular. But what exactly are they called?

The technical term for glasses that change color is photochromic lenses. These lenses are designed to adapt to various light conditions by darkening when exposed to UV (ultraviolet) light and becoming clear again when the UV light is no longer present.

How do photochromic lenses work?

Photochromic lenses contain special molecules that undergo a chemical reaction when exposed to UV light. These molecules are transparent indoors or in low-light conditions, allowing the lenses to maintain their clear appearance. However, when exposed to UV light outdoors, the molecules change structure and darken the lenses to provide UV protection and reduce glare.

It’s interesting to note that the reaction of photochromic lenses is reversible. Once you move back indoors or the UV light diminishes, the molecules return to their original state, causing the lenses to gradually become clear again.

Do photochromic lenses work for everyone?

Photochromic lenses are a great option for many people. However, their effectiveness can vary depending on factors such as the individual’s prescription and the intensity of UV light. For individuals who spend a significant amount of time outdoors, photochromic lenses can provide convenience by eliminating the need to switch between regular eyeglasses and sunglasses.

Are other names used for glasses that change color?

While the term “photochromic lenses” is the standard name for glasses that change color due to UV exposure, some popular eyewear brands have their own names for this technology. For example, Transitions® lenses is a widely recognized brand that offers photochromic lenses. Other brands may have their own proprietary names, but they all essentially refer to the same concept of lenses that adapt to changing light conditions.

  • Transitions® lenses
  • Light-adaptive lenses
  • Self-tinting lenses

Glasses that change color, technically known as photochromic lenses, are an exciting option for eyewear. They offer the convenience of adapting to various light conditions by darkening in UV light and becoming clear indoors. Photochromic lenses are a popular choice for many individuals, providing UV protection and reducing glare. Remember, different eyewear brands may have their own names for this technology, but they all serve the same purpose.

So, if you’re considering getting glasses that change color, make sure to ask your eyecare professional about photochromic lenses or brands like Transitions®. Enjoy the benefits of adaptive eyewear and experience enhanced visual comfort!
