Photochromic Glossy Black Sports Sunglasses | UV400 Protection

"Photochromic Style - Glossy Black: Transparent Photochromic Lens + Myopia Frame."

This is the Photochromic (color-changing) version of the high-performance ROCKBROS sports sunglasses, designed for athletes who require clear vision across varying light conditions. The included lens automatically adjusts its tint when exposed to UV light, eliminating the need to change lenses when transitioning from indoors to outdoors, or from shade to sun.

Key Features:

• Photochromic Technology: The main transparent lens automatically darkens when exposed to sunlight (UV light) and lightens indoors or in low-light conditions. This provides continuous protection and comfortable vision all day.

• UV400 Protection: The PC (Polycarbonate) lens provides 100% protection against UVA and UVB rays (up to 400nm), safeguarding your eyes from long-term sun damage.

• Impact-Resistant Lens: Made from high-toughness, flexible Polycarbonate, the lens is highly durable and shatter-resistant, offering protection from impacts and debris.

• Myopia Ready: Includes a Built-in Myopia Frame attachment, allowing prescription lenses to be easily mounted behind the main shield lens, accommodating users with nearsightedness.

• Lightweight Design: The glasses feature a pressure-free, lightweight frame (approx. 30g) with comfortable silicone earpieces, ensuring a secure and comfortable fit during cycling, running, or other intense activities.

• Built-in Sweat Bar: The frame includes an internal sweat bar to manage perspiration and prevent sweat from running into your eyes.
