## Long description

TIFOSI CRIT CLARION FOTOTEC sport sunglasses come as a complete lens set with interchangeable photochromic and tinted options to cover a wide range of outdoor light conditions. The included Clarion Red photochromic lens adjusts transmission based on ambient light, while the AC Red and Clear lenses provide fixed tints for moderate and low-light situations. The frame is designed for active use in cycling, running and general outdoor training, offering a secure fit and simple lens change system for on-the-go adaptation.
Advantages
The photochromic Clarion Red lens delivers variable visible light transmission for adaptive contrast and reduced glare as lighting changes. The AC Red lens enhances contrast and comfort in partly cloudy or lower-sun conditions, and the Clear lens is suitable for night or very low-light activities where maximum visibility is required. Lightweight frame construction and interchangeable lenses allow athletes to quickly respond to shifting light without replacing the entire eyewear. Lenses offer protective coverage to reduce eye strain and exposure to wind and debris while maintaining optical clarity.

How to use
Select the lens appropriate for current light conditions and install it into the frame using the manufacturer’s lens-change method. For rapidly changing light, use the photochromic Clarion Red to allow automatic darkening and lightening. Use the AC Red lens when moderate tinting improves contrast and reduces glare, and the Clear lens when minimal tint is required for low-light or indoor use. Clean lenses with a soft microfiber cloth and a lens-safe cleaning solution to maintain optical performance and avoid scratches. Inspect the frame and lens seating before each use to ensure a secure fit.
Usage recommendations
Store lenses and frame in a protective case when not in use. Avoid exposure to extreme heat or prolonged direct sunlight when stored to prevent deforming frame components. Replace lenses that show deep scratches or damage to maintain visual clarity and eye protection.
