Why Do Sunglasses Fog or Scratch So Easily on Treks?
You’ve just found the perfect viewpoint, the breeze is crisp, the trail behind you feels rewarding—and then your sunglasses fog up. Or worse, you notice fresh scratches across the lens that weren’t there five minutes ago. If this sounds familiar, you’re not alone.
Trekking is tough, not just on your body, but also on your gear. Among all your essentials, sunglasses quietly suffer the most. Between temperature swings, sweat, dust, and rugged handling, they wear out quicker than you think.
Let’s break down why this happens and how to keep your sunglasses adventure-ready for longer.
Why Sunglasses Fog Up So Fast
You’re climbing uphill, the cold air hits your face, and suddenly your lenses fog. Vision gets blurry, you pause mid-trek, trying to clear the mist.
This happens due to condensation—a basic reaction between warm air from your face or breath and the cold lens surface. High-altitude treks, with their unpredictable climate shifts, make it worse.
Top reasons your sunglasses fog:
- No anti-fog coating or ventilation
- Wearing buffs or scarves too close to your nose
- High sweat production during climbs
- Sudden temperature shifts as altitude changes
Basic sunglasses aren’t built to handle mountain moods. You need gear that’s engineered for these extremes.
The Scratch Struggle Is Real
Unlike fog, which eventually clears, scratches are permanent. You toss your sunglasses into your travel bags, or wipe them quickly with a dusty sleeve, but before you know it, those clear lenses are a scratched mess.
Why scratches happen on treks:
- No protective case
- Wiping with clothes, tissues, or napkins
- Rough packing alongside metal gear in travel bags
- Low-quality lens materials
Scratched lenses don’t just ruin visibility, they can also reduce sun protection and leave your eyes vulnerable to UV damage.

The Power of the Right Accessories
Fogging and scratches can also be influenced by how well your other accessories complement your eyewear.
For example, caps for men from Gokyo Outdoor Clothing & Gear are made using breathable, sweat-wicking fabric. These keep heat away from your face, preventing excess condensation inside your sunglasses.
Need more protection from the sun? Go for hats for men. With extended brims and ventilated crowns, these shield your head and neck on exposed trails, without causing heat buildup around your face.
And let’s not forget travel bags. These rugged, thoughtfully-designed bags from Gokyo Outdoor Clothing & Gear feature padded compartments, so you can safely store your eyewear, gear, and valuables. No more scratched lenses from cramming them into side pouches.
Trail Tips to Protect Your Sunglasses
If you want your sunglasses to last across multiple treks, a little care goes a long way:
- Carry a microfiber cloth and lens cleaner in your travel bags
- Never use your t-shirt or tissues to wipe your lenses
- Use a hard-shell protective case for storage
- Choose sunglasses that have an anti-fog system and ventilation gaps
- Loosen your caps for men or buffs when you feel heat building up
