Glasses

MTB glasses are much more than just an aesthetic accessory, they are part of the MTB outfit. They play an essential role in protecting the eyes against external elements (dust, mud, insects, UV rays), while guaranteeing clear vision to anticipate obstacles. Here is a complete guide on their characteristics and specificities to choose the ideal pair.

1. Essential roles of MTB glasses:

Eye protection: Against projectiles (gravel, branches), wind, and splashes.
Optimized vision: Improved contrast to better discern trail details.
Visual comfort: Reduction of glare and protection against UV rays.
Stability: Stays in place even on descents or intense efforts.

2. Technical characteristics of MTB glasses:

a. Types of glasses

Photochromic lenses

Features: Automatically adapt to ambient light, becoming lighter or darker.
Advantages: Ideal for outings where light conditions vary frequently (forests, open terrain).
Disadvantage: Slightly delayed reaction to change in brightness.

Polarized lenses

Characteristics: Reduce reflections on surfaces (water, rocks).
Advantages: Improve contrast and reduce visual fatigue.
Disadvantage: Less effective in areas of dense shade.

Interchangeable lenses

Characteristics: Possibility of changing color depending on light conditions (transparent, yellow, smoked, etc.).
Advantages: Great versatility for all outings.
Disadvantage: Requires carrying multiple glasses.

Mirrored lenses

Features: Reflective coating that blocks glare.
Advantages: Effectively protects against intense light.
Disadvantage: Limited use in low light.

b. UV protection

Essential criterion: Glasses must offer 100% protection against UVA and UVB to preserve eye health.

c. Anti-fog treatment

Prevents condensation, particularly important on slow climbs or during intense efforts.
Some glasses incorporate ventilation or specific treatments to limit this phenomenon.

d. Strength and durability

Lens materials:

Polycarbonate: Lightweight and impact resistant.
Mineral glass: Superior optical quality but more fragile.

Frame:
