WHY RUN WITH SUNGLASSES? BENEFITS FOR TRAIL RUNNERS AND ATHLETES
April 10, 2025 / 8-minute read
Sunglasses are more than just a fashion accessory. They have become an essential part of a runner's equipment, especially in trail running. Whether you're a seasoned athlete or a passionate amateur, wearing appropriate sunglasses can enhance your performance, comfort, and provide lasting eye protection.

BENEFITS OF SUNGLASSES FOR RUNNING:
+ UV PROTECTION
At high altitudes or during sunny outings, eyes are exposed to ultraviolet (UVA and UVB) rays that can damage the retina in the long term. Sports sunglasses with 100% UV protection are essential to prevent ocular risks.
+ GLARE REDUCTION
Glare from direct light or reflective surfaces (water, light-colored rocks, snow) impairs vision. Polarized sunglasses also filter out stray reflections, allowing for clearer vision, better contrast, and improved terrain anticipation.
+ IMPROVED CONCENTRATION AND VISUAL COMFORT
In trail running, eyes are constantly challenged: roots, stones, changes in elevation, etc. Well-designed sunglasses offer clear vision without eye strain, enabling runners to maintain focus longer without visual fatigue.
+ MECHANICAL PROTECTION
Low branches, insects, dust, wind: during trail running in nature, eyes are exposed to numerous elements. Durable sunglasses provide a physical barrier for running confidently.

WHY DOES ATHLETES WEAR SUNGLASSES?
For professional athletes, every detail matters. Sunglasses are a performance tool:
- Better perception of relief and terrain,
- Reduced mental fatigue from prolonged light exposure,
- Increased comfort and visual responsiveness.

CHOOSING SUNGLASSES FOR TRAIL RUNNING
Not all sunglasses are suitable for trail running. Here are essential criteria:
- Photochromic lenses: adapt to brightness (transitioning from light to dark according to sunlight), ideal for shaded or mixed zones.
- UV400 protection: essential for blocking 100% of harmful UV rays.
- Wraparound frame: ensures a secure fit and protects against lateral intrusions.
- Lightweight and ventilation: lightweight sports sunglasses with good anti-fog systems are essential for uphill and downhill runs.
