Core Functions of Sports Sunglasses

1. Eye Protection

• UV Blocking: Filters 99-100% of UVA/UVB rays (UV400 rating) to prevent cataracts and macular degeneration.

• Impact Resistance: Made from shatterproof materials like polycarbonate (PC) or Trivex, meeting standards like ANSI Z87.1 (USA) or EN 166 (EU) for safety.

• Debris & Wind Barrier: Wrap-around frames and snug fits keep dust, bugs, and wind from irritating eyes.

2. Visual Enhancement

• Polarized Lenses: Reduce glare from water, roads, or snow, improving clarity (e.g., spotting obstacles in cycling or golf).

• Tint & Contrast Adjustment:

• Amber/Yellow: Boost contrast in overcast/low-light (hiking, running).

• Gray/Green: Maintain natural colors for balanced light reduction (water sports, driving).

• Rose/Red: Enhance depth perception in fog or snow (skiing).

• Photochromic Lenses: Darken/lighten automatically with changing light (ideal for sports in variable conditions, like cycling or tennis).




3. Comfort & Stability

• Lightweight Frames: Materials like TR90 nylon or carbon fiber minimize fatigue during long activities.

• Anti-Slip Features: Silicone nose pads and temple grips prevent slippage during sweat or movement.

• Aerodynamic Design: Reduces wind resistance and fogging (common in cycling or running models).
