Transition Lenses

What are transition glasses?

Transition lenses are a brand of photochromic lenses that are designed to darken when exposed to UV light. A special photochromic dye is used in transition lenses that react to UV light, causing the lenses to darken. When the lenses are not exposed to UV light, they gradually return to their clear state.

There are available in gray, brown, and green colors. They are also available in different materials, including polycarbonate lenses, high-index lenses, and CR-39.

It is worth noting that not all photochromic lenses are Transitions lenses. There are other brands of photochromic lenses as well, but Transitions is the most well-known.

How do photochromic lenses and transition lenses work?

One key difference between photochromic lenses and Transition lenses is the speed at which they change. The transition lenses are faster and more responsive to changes in light conditions. They can change from a clear state to a dark in as little as 30 seconds, while photochromic lenses may take several minutes.

Pros and cons of transitions glasses

Transitions 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 transitions lenses:


  1. Convenience: Transitions lenses eliminate the need to carry around an extra pair of glasses or sunglasses and switch between different pairs of eyeglasses.
  2. Protection: Transitions lenses help to protect your eyes from harmful UV rays. They are designed to automatically darken when exposed to sunlight, which helps to reduce glare and eye strain.
  3. Comfort: Transitions lenses offer a comfortable and seamless transition between indoor and outdoor environments. They allow you to see clearly and comfortably in any lighting condition.
  4. Cost: Transitions lenses tend to be more expensive than regular prescription lenses. However, the cost may be worth it if you value convenience and eye protection.
  5. Reaction time: Transitions lenses can take a few minutes to fully adjust to changing light conditions. This means that if you walk from a dark room into bright sunlight, you may experience some temporary discomfort or glare.
