1. What are photochromic lenses?

Photochromic lenses, often referred to as light-intelligent lenses, stay clear indoors or when away from UV light. Once exposed to sunlight, they automatically darken, adapting to the light conditions. This makes them an ideal choice for individuals who want the convenience of combining both eyeglasses and sunglasses in one pair.

2. How do photochromic lenses work?

Photochromic lenses contain molecules such as silver halide or other compounds that react to ultraviolet (UV) light. When exposed to UV rays from the sun, these molecules change their structure, causing the lens to darken. Once you move out of the sunlight and UV exposure decreases, the molecules revert to their original state, and the lenses become clear again.

3. Who should consider photochromic lenses?

• People who frequently move between indoor and outdoor environments.
  
• People who want UV protection without carrying a second pair of sunglasses.
• People who are light sensitive or have eye surgery.

4. Popular brands of photochromic lenses

• Transitions®: One of the most well-known brands for photochromic lenses.
  
• Sensity® by Hoya: Known for quick transitions and a range of tint options.
  
• PhotoFusion® by Zeiss: Offers fast reaction times and excellent optical clarity.

5. How many brands of photochromic lenses does Sllac have?

Sllac offers both standard photochromic lenses and Transitions® lenses, allowing customers to choose based on their specific needs and preferences.

6. What's the difference between photochromic lenses and Transitions®?

All Transitions® lenses are photochromic, but not all photochromic lenses are Transitions®. Other brands like Hoya or Zeiss also offer similar lenses, but Transitions® is widely recognized for its fast transitions, natural colors, and customizable features.

Photochromic lenses offer a convenient, stylish, and protective solution for people who want seamless transitions between indoor and outdoor lighting. While they may not replace dedicated sunglasses in every situation, they’re a versatile option for everyday use. Consult your optometrist to learn more about photochromic lenses and find out if they’re the right fit for your lifestyle and vision needs.
