KOO Demos Glasses

The KOO Demos Glasses are a single-lens sport eyewear frame built for cyclists who want a wide, unobstructed field of view without the compromises that come with cheaper optics. Sitting in KOO's performance-oriented lineup, the Demos pairs Zeiss polycarbonate lenses with a practical, rider-focused frame design that holds up across varying light conditions and long hours in the saddle. Whether you're grinding through a morning group ride or pushing through an afternoon road race, the optics are doing their job quietly in the background.

The lens itself is treated with an anti-reflective coating that reduces eye strain and improves contrast — a small detail that matters considerably on multi-hour efforts. Four ventilation ports are built into the frame to keep air moving across the lens and minimize fogging during intense efforts or in humid conditions. An adjustable, foldable nose-piece and MEGOL elastomer grips on the frame allow you to dial in the fit so the glasses stay put as sweat builds up — no mid-ride adjustments required. The range of colour options includes both standard tinted lenses at varying protection levels and a photochromic option that adapts to changing light automatically.

Design Benefits

1. Optics built for performance riding: Zeiss polycarbonate lenses with anti-reflective coating are designed to deliver consistent clarity and contrast — reducing the fatigue that builds up when your eyes are working harder than they need to across long rides or variable conditions.
2. Fit that holds under pressure: The combination of MEGOL elastomer grips and an adjustable nose-piece means the Demos is designed to stay secure as conditions get sweaty. You shouldn't have to think about your glasses when you're riding hard.
3. Ventilation where it counts: The four-port ventilation system keeps airflow moving across the inside of the lens, addressing one of the more frustrating realities of wearing cycling eyewear — fogging during high-output efforts or cool, damp days.
