Prioritize wraparound protection, sturdy frames, and lenses with full UV protection. Side shields should block peripheral glare and wind, and ensure a comfortable fit with your helmet.

Lens quality (UV protection, anti-fog, glare reduction), side shield integration, fit and coverage, weight, and durability. Balance protection with comfort and helmet compatibility.

Look for polarization for bright snow glare, photochromic or interchangeable lenses for changing light, and good venting to reduce fog. Lens color can also affect contrast in snowy or rocky terrain.

Think about typical conditions (bright sun at high altitude vs. overcast), whether you’ll wear a helmet with a visor, and if you need lenses that work well with other gear. Choose models with secure wrap, comfortable nose pads, and compatible side shields.
