There’s no denying that most people rely heavily on their eyesight for sensory input about their environment. In fact, modern society operates on this assumption, with transportation, communication, and nearly every other aspect of our lives dependent upon seeing in order to participate fully. While there are, of course, services in place to aid those that have inadequate vision, most of us would rather preserve our eyesight if at all possible. However, the thought of putting chemical drops in your eyes, taking prescription medication, or using plastic or glass lenses to improve your vision may not sound very appealing if you’re on a crusade to change your life for the greener. So here are just a few natural and eco-friendly solutions that could ensure your vision lasts longer.
The first thing you can do is exercise your eyes. If you use your computer frequently for work or recreation (as many people in the modern world do) you may have noticed that your eyesight is slowly deteriorating year upon year. This is because your eyes are becoming weaker as you force them to focus at a fixed distance for long periods of time. So when you want to look at something closer or further away your eyes cannot respond as quickly or accurately as they once could. This eye strain can cause a number of vision-related problems. Luckily, there are eye exercises that can help you. Ophthalmologists generally recommend that you implement the 20-20-20 rule when using your computer (or other monitor); look at something twenty feet away for at least twenty seconds after every twenty minutes of screen time.
But what if you don’t spend a lot of time looking at monitors? As it turns out, degenerative eye problems were around long before the invention of TVs, computers, and mobile devices. And one good way to combat them is through a proper diet that is high in particular nutrients. Vitamins A, B, C, and E are essential to your overall health, providing all kinds of benefits, and one of them is healthy vision; you can fill your daily requirement easily with any average adult multivitamin. But you may also want to consider adding eye-healthy omega-3 fatty acids (found in high doses in fish like salmon, as well as walnuts and flaxseed), lutein (present in egg yolks and leafy greens), taurine (which occurs naturally in some meats, but is generally taken as a supplement), and minerals like zinc, magnesium, and selenium (which have been shown to help prevent and slow age-related macular degeneration, or AMD).
Of course, there is one last option. If your vision is already starting to fail and even your best efforts at consuming a targeted diet and exercising your eyes are not enough, you could still opt for eco-friendly eyeglasses to help preserve your vision. Several companies now offer frames made from sustainable wood and recycled plastic or metal, as well as recycled lenses or those created with less pollution and waste. You might not be able to justify the colour contacts you’ve always wanted to try (although there have been some environmental advances of late in this field, as well). But you can definitely find tools that will help to improve your eyesight while living up to your green ideals.
