Anyone who has ever been called four eyes may have felt a little down in life because of their specs, but childhood teasing does not last forever. Those four-eyed individuals will one day be able to rub those bullies noses into the fact that those glasses could be the difference between life and death.
There are several everyday items that can be used to survive in the wilderness, shoelaces to make rope, socks to filter water or a volleyball named Wilson to have conversations with.But one of the most useful at-home items someone can use in the wilderness are eyeglasses.
Notice how the people from Walking Dead, never use glasses to survive. And they keep dropping like flies.
Obviously glasses help people see, but out in the wilderness it can be more than that. Sunglasses or transition lenses can protect from blindness against the elements. If someone is climbing a mountain completely covered in snow, there is one basic color, and that is white. The problem with this is when the sun comes out, that white snow becomes blinding. Another area in which sunglasses can protect eyesight is out in the ocean. Just like snow, when the sun shines onto the water it can become extremely bright. A pair of sunglasses protects the eyes from the overwhelming brightness of the snow or water and lets an adventurer see clearly without damaging their eyesight.
Protection from the Elements
Not only do glasses guard against the sun, they also guard against injury. If someone is in a desert area, glasses can be essential to protecting the eyes from the sand. If winds come up, sand can be a vicious thing and having it slice into the eyes can be extremely serious. Even is someone is not in a desert area, a forest or jungle with high winds can carry a lot of small harmful objects that can wedge themselves into an eye.
Starting a Fire
One of the most well-known uses for glasses in the wilderness is starting a fire. The lens inside a pair of glasses works the same way as a magnifying glass. When the sun hits a lens it creates a beam of light that converges all the energy of the sun into one small area, which creates heat. The thicker the lens the better because it results in a stronger conversion. Fire means life when trying to survive. It is what makes food, filters water and provides warmth. A pair of glasses starting a fire can truly save someone’s life.
Create a Useful Tool
The lenses inside a pair of glasses can be used for more than making fire. With the assistance of a sharp rock, a lens can be filed down to create a small sharp knife. This can be helpful to use as a weapon but also a tool. A knife can help cut roots or plants to eat. It can also be useful for cutting meat. If someone has caught an animal, the knife can be used for skinning and cutting out the meat. It is helpful for gutting and fileting fish as well.
Signal for Help
Similar to the process of making fire, eyeglasses can partner with the sun to create a help signal to oncoming travelers. When the light bounces off or transmits through a lens, it results in a small flash or glare. Travelers can often be too far off to hear someone shouting and may not be paying close enough attention to see a someone who is stranded. A glint of sunlight or a glare can be seen farther off, and if someone can manage to shine it into someone’s eyes, they will be more likely to turn around and notice that someone needs help.
If someone has wire frame glasses, the temples of the glasses can be used to create a fish hook. The temple tips can be bent into a hook shape and sharpened with a rock. If someone can find some strong roots or vines along with a small bug, they have just created their own fishing pole and dinner is a catch away.
Survival of the fittest may have just turned into survival of the nerdiest, so before someone starts a new adventure, grabbing some Ray Bans glasses could very well save their life.
