The 6 Best Mountaineering Sunglasses
Mountaineering can be an exhilarating adventure, but it also exposes you to harsh sunlight and reflective snow, which can be detrimental to your eyes. To ensure a safe and enjoyable ascent into high-altitude environments, you need specialized sunglasses designed for mountaineering. In this article, we’ll explore the top mountaineering sunglasses available, providing you with valuable insights to make an informed choice.
Understanding the Need for Mountaineering Sunglasses
Mountaineering sunglasses differ significantly from standard eyewear due to their unique features tailored to the challenges of high-altitude environments. These sunglasses are designed to protect your eyes from intense sunlight, UV radiation, and glare off snow and ice. They often include side shields to block light from all angles and ensure optimal visibility.
How to Choose the Right Size
Selecting the correct size of mountaineering sunglasses is crucial for comfort and protection. Sunglasses typically have three measurements: lens width, bridge size, and temple length. A suitable size ensures a snug fit, preventing light from entering around the frames. Remember to measure your head or try on various sizes to find the perfect fit.
Visible Light Transmission (VLT) Ratings
Visible Light Transmission (VLT) is a critical factor in choosing mountaineering sunglasses. For this purpose, sunglasses fall into four categories based on their VLT rating. When mountaineering, it’s essential to use Category 3 (18%-8% VLT) or Category 4 (<8% VLT) lenses. Category 3 lenses are ideal for mixed conditions, while Category 4 lenses are necessary for sunny days on glaciers.
Coverage with Side and Bridge Shields
When hiking on snow, sunlight reflects not only from above but also from the sides and below. Mountaineering sunglasses are equipped with side shields to block light from entering around the lenses. Some models also include bridge shields, further enhancing protection. High-quality models allow you to remove these shields when needed, offering versatility for various conditions.
Materials Matter
The material used for the lenses and frames of mountaineering sunglasses significantly impacts their durability and weight. Polycarbonate lenses are an excellent choice due to their durability and resistance to impact. Frames can be made of either polycarbonate or metal. Metal frames are more resistant to bending but tend to be heavier, while polycarbonate frames are lightweight.
Adjustability, Fit, and Helmet Compatibility
A comfortable fit is essential for mountaineering sunglasses, especially when wearing them for extended periods. Look for sunglasses with adjustable arms and nose pads, as they allow you to block out more light and tailor the fit to your face. Additionally, consider sunglasses that are compatible with climbing helmets for technical ascents.
