Cycling Photochromic Sunglasses Rockbros model 1024390 with UV400 filter, black

Rockbros cycling photochromic sunglasses model 1024390 in black combine adaptive lens technology with a lightweight frame to provide variable light attenuation and full coverage for cycling and outdoor activities. The lenses feature a UV400 filter that blocks UVA and UVB radiation, while the photochromic treatment darkens the lenses in strong sunlight and clears them in low-light conditions. The overall design is optimized for cycling: wrap-around lens geometry offers broad peripheral protection and reduces wind and debris exposure during rides.

Advantages

These Rockbros sunglasses offer continuous eye protection across changing light conditions because the photochromic lenses respond automatically to UV intensity, reducing the need to switch eyewear. A UV400 filter ensures high-level protection against harmful ultraviolet rays. The lightweight frame and full-coverage lens shape deliver stable fit and good field of view for cycling posture. Materials and construction prioritize comfort during prolonged wear and reduce pressure on the nose and temples.

Suitable for

• Road cycling and commuting
• Mountain biking and trail riding
• Urban cycling and everyday outdoor use
• Sport activities where eye protection and adaptive shading are needed

Key specifications

How to use

Wear the sunglasses during cycling or outdoor activities to benefit from automatic light adaptation and continuous UV protection. The photochromic lenses will darken when exposed to brighter sunlight and return to a lighter state in shaded or low-light environments. Adjust the frame to sit comfortably on the bridge of the nose and behind the ears; ensure the lenses provide unobstructed peripheral vision in your riding position. Clean lenses with a soft microfiber cloth and mild lens cleaner to maintain optical clarity.

Usage recommendations

For optimal performance, allow a short period for the photochromic lenses to reach their adapted tint after moving between light conditions. Store the sunglasses away from extreme heat when not in use and avoid abrasive materials when cleaning to preserve the lens coating and UV protection.
