☀️ How Photochromic Lenses Work

Photochromic lenses contain molecules that react to ultraviolet (UV) light. When exposed to sunlight, these molecules change shape, causing the lenses to darken. Indoors, where UV light is minimal, they return to a clear state.

Key benefits:

• Adapts automatically to different light conditions

• Eliminates the need to switch between sunglasses and regular glasses

• Reduces eye strain in changing environments

🧠 Why UV Protection Is Essential

Even as they change tint, high-quality photochromic lenses offer UV400 protection, blocking 100% of UVA and UVB rays. This means your eyes are shielded from harmful radiation whether your lenses are dark or clear.

Pro tip: Not all transition lenses darken equally in vehicles, since most car windshields block some UV rays. If you spend significant time driving, consider pairing with a lightweight pair of polarized sunglasses for maximum protection.
