Bollé Shifter Sunglasses - Black Matte, TNS Gold

These sunglasses are designed for high-performance sports such as cycling, running, trail running, and other outdoor activities where superior vision protection and a secure fit are essential.

The included SLF Cat. 3 lens is optimized for sunny to partially cloudy days. For very low light or extremely bright, snow-covered conditions, a different lens category might be more appropriate.

You can adjust the fit by gently bending the nose pads to change their position on your nose and by adjusting the temple tips to rest comfortably and securely behind your ears.

Thermogrip is a special hydrophilic rubber material used on the temple tips. It becomes grippier when it gets wet, ensuring the sunglasses stay securely in place even when you sweat.

While the product description doesn't explicitly mention interchangeable lenses, the focus is on the integrated Hydro Lens Technology. For lens replacement inquiries, it is best to contact Bollé customer support.

The Bollé Shifter Sunglasses come with a strong EVA Sport Performance case to protect them when not in use.

Gently clean the lenses with a soft, lint-free microfiber cloth. For tougher dirt, use a dedicated lens cleaning solution. Avoid abrasive materials and household cleaners.

Adjust the nose pads for a tighter fit and ensure temple tips are positioned correctly on your ears. If slipping persists, consider if the fit is suitable for your face shape.

The SLF Cat. 3 lens is designed for bright conditions. For lower light, consider swapping to a different lens if available or removing the sunglasses if visibility is compromised.

Ensure proper ventilation by adjusting the frame fit. Some fogging is natural with intense activity; clean the lenses with an anti-fog solution if this is a persistent issue.

Avoid placing lenses on hard surfaces. Clean gently with a microfiber cloth. Significant scratches may require lens replacement; contact customer support for options.
