The Best Sunglasses for High-Altitude Adventure

The Best Sunglasses for High-Altitude Adventures

Sunglasses are more than a fashion accessory when climbing Kilimanjaro—they’re a critical piece of gear to protect your eyes from intense UV rays and glare from snow or rocky surfaces. Here’s how to choose the perfect pair for your trek.

1. Why Sunglasses Are Essential at High Altitudes

• Increased UV Exposure:

  • UV intensity increases by about 10% for every 1,000 meters (3,280 feet) of elevation gain.

  • Without protection, prolonged exposure can cause snow blindness or eye irritation.

• Glare from Terrain:

  • Snow, ice, and even dry rocks reflect sunlight, increasing the risk of eye strain.

Pro Tip: Sunglasses with full UV protection are non-negotiable for your safety.

2. Features to Look For

1. UV Protection

• Requirement:

  • Look for sunglasses with 100% UVA and UVB protection.

• Bonus:

  • UV400-rated lenses block wavelengths up to 400 nanometers, offering maximum protection.

• Caution:

  • Some trekkers find polarized lenses distort depth perception—test them before your trek.
