Product Introduction
Optical Convergence: Behind-the-Windshield Activation for Drivers
Standard photochromic lenses often fail drivers because car windshields are designed to block the UV rays required to trigger the darkening process. Our Driving Optimized Photochromic lens solves this problem using a specialized "Visible Light Activation" technology. These lenses are engineered with a hybrid photochromic matrix that reacts not only to UV light but also to the visible spectrum of sunlight. This allows the lens to achieve a comfortable tint (up to 50% darkness) even inside the car, significantly reducing dashboard glare and the blinding brightness of the road ahead. In the open air, the lens darkens even further to a Category 3 sunglass level. Furthermore, the base tint is often specifically tuned to enhance contrast—improving the visibility of traffic lights, brake lamps, and road signs. To ensure safety, the fading speed is optimized to allow for clear vision when driving into tunnels or underpasses. This lens is the perfect companion for long-distance drivers, commuters, and road-trip enthusiasts who require a dynamic lens that works as hard inside the vehicle as it does outside.

Frequently Asked Questions (FAQ)
- Q: Why do these work in the car when others don't?
- A: They react to visible light, which passes through windshields.
- Q: Do they get as dark as sunglasses?
- A: Outside the car, yes. Inside the car, they reach a moderate tint.
- Q: Is it safe for night driving?
- A: Yes, they return to clear (over 85% transmission) at night.
- Q: Does the lens color affect traffic lights?
- A: No, the tints are calibrated to maintain color signal recognition.
- Q: Are they polarized?
- A: We offer a specialized "Drive-Polar" version for maximum glare kill.
- Q: How fast is the fade speed for tunnels?
- A: They are engineered for high-speed fading to ensure safety.
- Q: What index is available?
- A: Most commonly 1.56 and 1.60 for driving durability.
- Q: Do they block UV?
- A: Yes, 100% UV400 protection is always active.
- Q: Can I use them for reading?
- A: Yes, they can be made as progressives or single vision.
- Q: Why are they a different price?
- A: The visible-light reactive molecules are a premium specialized material.
