When most people pack for a trek, they think of shoes, water, energy bars, and maybe some sunscreen. But one thing that often gets overlooked is eye protection. And that’s where many go wrong—because your eyes are just as exposed to the elements as your skin.
Let’s explore why UV rays are a serious concern during treks and how ignoring them could harm your eyes in ways you may not expect.
UV Exposure Rises with Altitude
Here’s a surprising fact: UV radiation increases by roughly 10 percent for every 1000 meters of elevation. That means if you're trekking up to places like Harishchandragad or Kalsubai, your eyes are being hit with much stronger UV rays than you experience in the city.
Even if the sky is cloudy, UV rays don’t take a day off. They can easily penetrate cloud cover and continue affecting your eyes. That’s what makes protection on treks essential—not optional.
What Really Happens to Your Eyes in the Wild
Extended exposure to UV rays without proper protection can cause real damage to your eyes. Here are a few things that can happen:
-
Photokeratitis: A painful condition often described as "sunburn of the eyes." It causes temporary vision loss, irritation, and sensitivity to light.
-
Cataracts: Long-term UV exposure can cloud the lens of your eyes, reducing your ability to see clearly.
-
Macular Degeneration: This condition affects your central vision and becomes more likely with regular exposure to unfiltered sunlight.
-
Retinal Damage: When sunlight reflects off surfaces like rocks or even snow, it hits your eyes from different angles, increasing the risk of damage.
Why Not Just Wear Any Sunglasses?
This is where most people get it wrong. Ordinary sunglasses might make the world look dimmer, but they don’t always block UV rays. In fact, cheap sunglasses can be more harmful. Your pupils dilate because of the darker lens, allowing more UV radiation to enter—making things worse.
What you really need is a pair of sunglasses that offer true UV protection, a wide coverage area, and are built to withstand adventure.
Sunglasses Built for Trekkers and Trails
At Opticsfit, we design sunglasses that are made for rough use and outdoor endurance.
Take our Kratos Series for example. These sunglasses have unbreakable lenses, offer UV400 protection, and stay strong whether you’re climbing, running, or slipping on a rocky trail. We’ve tested them in real-world conditions—and they don’t quit.
If you're looking for something lighter for shorter treks or casual climbs, the RidgeFlex Series offers lightweight frames with excellent grip, glare reduction, and all-day comfort.
A Small Step That Makes a Big Difference
Investing in trekking shoes or a hydration pack is great—but protecting your eyes should be on that list too. Vision loss or eye strain might not show up on day one, but the risks add up over time.
So, before your next outdoor adventure, ask yourself: Have you packed your sunglasses?
If not, it’s time to make space for a pair that protects, performs, and keeps you going—wherever the trail leads.
