⚡ At a Glance
- • Wearing Comfort: Ultra-light 30 grams TR90 frame, flexible fit that reduces pressure on nose and temples
- • Best for: Cyclists and outdoor athletes who need adaptive lenses and broad eye coverage
- • Not ideal for: Users who prefer a fixed tint rather than photochromic lens changes
Photochromic lenses adjust tint based on UV exposure while UV400 rating blocks harmful rays. Lightweight TR90 construction and a wide-field design suit sustained outdoor use.
Clear vision in changing light, with photochromic lenses
Lenses automatically change tint according to UV exposure, shifting from lighter to darker tones to match ambient brightness. The transition responds directly to UV levels rather than time of day.
Automatic darkening reduces glare and removes the need to swap eyewear during variable conditions, keeping vision consistent on long outings.
Complete UV defence, with UV400 lenses
UV400-rated lenses block wavelengths up to 400 nm, covering UVA, UVB and UVC radiation. The specification ensures full-spectrum protection from common solar ultraviolet risks.
Full protection lowers risk of sun-related discomfort and helps preserve long-term eye health during prolonged outdoor exposure.
Comfort and stability for long outings, with TR90 frame and wide-field design
TR90 material combines high strength with low weight and flexibility, while a wider lens shape expands peripheral coverage and reduces air resistance. The full-frame design also shields eyes from wind, dust and insects.
A barely noticeable 30 grams on the face and a secure fit maintain comfort on long rides, improving focus and safety in fast conditions.
