Eyewear

Good cycling eyewear does three things: it keeps debris, insects, and UV out of your eyes; it manages contrast shifts between shade and open road; and it stays put at sprint or descending speed. The Eyewear collection at RA Cycles covers the full range across Oakley, Assos, and KOO — three brands that approach the problem differently but with the same level of seriousness.

Oakley brings the widest selection, from the Sutro and Sphaera shield styles to the race-specific Kato and Velo Kato. Lens options span PRIZM road, polarized, and photochromic — the photochromic variants transition from clear to dark across changing light conditions without a lens swap. Assos's Zegho G2 is the brand's aero-optimized racing glass, engineered to sit flush with helmets and reduce drag at speed. KOO uses Zeiss lenses as standard, with a fit refined through their BORA-hansgrohe pro team partnership and a prescription clip-in system for riders who need optical correction on the bike.

About Cycling Eyewear

Lens choice matters more than frame choice for most riding conditions. PRIZM road lenses filter wavelengths that obscure road surface texture — useful for road and gravel where you want to read what's ahead of your tire. Polarized lenses cut glare from wet roads and standing water. Photochromic lenses are the most versatile option: a single pair that adapts from pre-dawn light through midday sun without requiring a swap. For frame fit, cycling eyewear needs to sit close enough to block peripheral wind and light without fogging — shield styles like the Sutro and Sphaera provide maximum coverage and a clean aero profile; frame-and-lens styles like the Flak 2.0 and Radar allow more airflow for climbing and warm conditions.

Oakley is the largest brand in the collection, with PRIZM lenses running through most of the lineup and photochromic options in the Sutro Lite S, EVZero Blades, and CYBR series. The Meta Vanguard sits at the top of the range with smart frame technology. Assos's Zegho G2 comes in two configurations — the Dragonfly (frameless, minimal profile) and the Interceptor — both designed to integrate with the Equipe kit system and reduce aerodynamic disruption. KOO uses Zeiss lenses as standard equipment and offers the Optical Clip Evo for riders who need prescription correction; the brand's glasses are tested and worn by the BORA-hansgrohe WorldTour team.

50 YEARS AND COUNTING
