Cycling photochromic glasses Rockbros 189105 with UV protection and corrective lens insert

Rockbros 189105 cycling photochromic glasses combine adaptive lens tinting and UV protection to support safe vision across varying daylight conditions. The lenses darken in bright sunlight and lighten in low-light environments, reducing the need to change eyewear during a ride. A removable corrective lens insert accepts prescription lenses, allowing riders who require vision correction to use the glasses without compromising fit or protection. The design focuses on lightweight comfort, aerodynamic fit and barrier protection against sun, wind and debris for both road and off-road cycling.

Advantages

The photochromic lenses provide continuous adaptation to light intensity, improving visual comfort from bright midday sun to shaded trails. Integrated UV protection helps shield eyes from harmful UVA and UVB rays. The removable corrective lens insert enables secure use with prescription lenses while maintaining the frame’s stability and coverage. A lightweight frame and adjustable nose and temple fit ensure long-wear comfort and reduced pressure points during extended rides.

Suitable for

• Road cycling where changing light conditions occur (tunnels, overpasses, variable cloud cover)
• Mountain and gravel riding with shifts between open and shaded terrain
• Commuting and urban cycling to protect eyes from sun, wind and airborne debris
• Riders who require prescription lenses and need a secure corrective insert

Key specifications

• Photochromic lenses that adjust tint according to ambient light
• UV protection against UVA and UVB radiation
• Removable corrective lens insert compatible with prescription lenses
• Lightweight, impact-resistant frame construction suitable for active use
• Adjustable nosepiece and temple arms for personalized fit

How to use

Put on the glasses and adjust the nosepiece and temple arms so the frame sits comfortably and provides full coverage around the eyes. When using prescription lenses, install the removable corrective lens insert according to the manufacturer’s alignment instructions and secure it within the frame before riding. Allow the photochromic lenses a short time to adapt when moving between different light conditions. Clean lenses with a soft microfiber cloth and approved lens cleaner to maintain optical clarity and extend service life.

Usage recommendations

For optimal performance, store the glasses away from extreme heat and harsh chemicals. Replace scratched or heavily worn lenses to preserve UV protection and photochromic response. Regularly check the corrective insert fit if you use prescription lenses to ensure secure positioning during active cycling.
