There’s a well known saying ‘Its better than a poke in the eye with a blunt stick’ which is a phrase used to say that your current situation could always be worse. Having been poked in the eye a number of times over my life by branches and various other bits of shrubbery I can agree with this idiom. We often spend copious quantities of time choosing every last bit of hiking gear, I know I do; but how much thought do we put into protecting our eyes?
This article discusses eye care on the trail and looks at the steps to ensure we provide adequate care for one of our most sensitive body parts.
Firstly lets look at our senses. In addition to our sight we also have our taste, touch, hearing and smell. All of these play a role in how we view the world but we receive around 80% or our impressions through out sight (Zeiss). In addition our sight also impacts on our other senses with yellow, orange and red food perceived to be sweeter.
When we hike we often do so to be out in nature, to enjoy the views. For most of us we would rate our vision as the most important of our senses.
Even on reasonably groomed trails, the trees and shrubs you came across often grow onto the trail, particularly early in the season before maintenance crews have had a chance to trim them back. Or maybe you are going off trail and bushbashing. As previously mentioned I have regularly managed to poke myself in the face, usually with smaller sticks and twigs but occasionally larger sticks that have resulted in damage to the edges of my eyes.
It’s not just the large physical stuff that can impact on your eyes. Dust and sand being blown about, particularly in arid regions, can be a major issue and I’m sure everyone has had grit in their eyes at one stage or another that you struggle to remove. It’s bad enough when you are at home trying to get a bit of grit out of your eye but imagine having this issue when out in the bush when your hiking.
Grass trees on the Bibbulmun Track. These iconic plants were my companions for sections of the track and always seemed to have their thin spiky leaves growing just at eye height, at least for me. Some trail maintenance crews had trimmed the ones show above but there were a lot that were across the trail back; but not always.
Usually when we are wearing sunglasses we do so for a number of reasons. As mentioned above physical protection from sharp spiky plants is just one reason. In addition we usually also want protection from:
In regards to the impacts of the sun on our eyes I, like most people, was aware that excess exposure to the sun can cause damage to the eyes but wasn’t really sure of the exact impacts.
Exposure to UV radiation can cause a number of issues including:
In doing the research for this article I learnt a few things I wasn’t aware of, at least from a factual perspective.
I have spent most of my life working outdoors including in and around the ocean and even wearing sunglasses for much of this time however my eyes still show the effects of long term exposure to the sun with deep wrinkles and baggy eyelids
A descent broad brimmed hat reduces the suns impact on your whole head including your eyes. I find that even when I have good quality sunglasses (even category 4) that I will always get a bit of glare coming through to the eyes. A broad brimmed hat will help reduce the suns impact in combination to sunglasses.

Sunglasses and fashion spectacles are classified into five categories by their performance suitability for use in certain conditions. choose the correct category for your activity but as far as hiking goes you should be looking at category 2-4. The categories are as follows:
Julbo Micropres GT Sunglasses. These are category 4 sunglasses that provide a high level of glare protection particular in snowy conditions when you get a lot of reflection. You should not use category 4 sunglasses for driving
The importance of our eyes to how we interpret our surroundings is almost immeasurable so taking good care of them is essential both in normal life as well as when we ‘go bush’ and have to deal with a more unruly environment. Don’t relegate eye care to the cheapest and quickest option that you can but spend some time to get it right. Choose a good pair of sunglasses that meets your needs and that’s within your budget and if you have to go cheaper on other prices of gear if that means you are getting the right pair. Don’t forget to match up your sunglasses with a suitable hat that not only protects your head from sunburn but also shades your eyes.
