Now that summer is in full swing, you’re probably taking measures to guard against sunburn. But what are you doing to protect your eyes?
You may not realize it, but your eyes can get sunburned too. And while eye drops and a little rest will help heal your bloodshot, irritated and gritty eyes, sun damage to your peepers can lead to further problems down the road.
In particular, there’s a part of your eyes called the macula. It protects your central sight from damage caused by blue light from the sun’s rays.
The problem is that, the more unprotected sun exposure your eyes have, the thinner your macula becomes. The UV rays from the sun also trigger the production of drusen. These are yellow deposits composed of fats, protein and cell waste that collect under your retina.
Now, both of these occurrences are linked to the development of the dry form of age-related macular degeneration (AMD). This is one of the leading causes of blindness in the world today.
Worse, when membranes near drusen deposits begin to break down, it can cause new blood vessels to start growing. These blood vessels are fragile and tend to leak blood and fluid under the macula. This is the wet form of AMD.
All of this damage makes it hard to work or read in dim-light conditions. Words become blurred and your central vision may become fuzzy and hazy, even when you’re looking at something right in front of you.
Here’s the thing. There is no cure for macular degeneration.
Why You Need a Good Pair of Sunglasses
Once you reach the advanced stage of dry AMD, there is no medical treatment to prevent further vision loss.
If you develop the wet form, the best you can hope for are injections into your eyes to slow down the leakage. (Or if you’re brave, you can undergo laser surgery to destroy the leaky blood vessels. However, laser treatment can also destroy surrounding tissue – which could further damage your vision.)
But there are several things you can do to prevent the development of AMD.
Since the UV rays from the sun have a direct impact on factors related to AMD, a good pair of sunglasses is your first priority.
Maybe you already wear sunglasses on a regular basis. If you do, I’ll bet you bought them with only three things in mind: Comfort, style and glare protection.
Well… just because those dark lenses block the sun’s glare doesn’t mean they block UV rays. This is a very common misconception among sunglass wearers.
Instead, your main concern when buying sunglasses should be UV protection. Specifically, your sunglasses should bear a label stating that they block 100% of UVA and UVB rays. They’re going to cost a little more, but they can still be stylish and comfortable.
However, they won’t do much good if you stash them in your glove box or leave them laying on the coffee table while you wait for a bright and sunny summer day.
UV rays are present whether it’s sunny or cloudy, all year round, and even when you’re driving in your car.
Top Nutrients to Protect you from Sight-Robbing AMD
In addition to wearing sunglasses, there are certain nutrients that can protect against AMD – and help prevent it from progressing if caught in early to intermediate stages.
You see, your macula is comprised almost entirely lutein and zeaxanthin. A lack of these carotenoids can cause your macula to thin and degenerate.
But when you get plenty of them, they protect the macula by absorbing the harmful rays from the sun. They also act as powerful antioxidants to shield your eyes from free radical damage.
Plus, people with the highest intakes of lutein and zeaxanthin are less likely to develop drusen and leaky blood vessels behind the macula. They also have a greatly reduced risk of developing AMD.
Some foods that contain these powerful antioxidants are dark leafy greens such as kale, turnip greens, collards, spinach and chard. So it’s not hard to get more of them in your diet.
But for maximum protection, I recommend looking for an eye formula that contains at least 12 mg of lutein and 2 mg of zeaxanthin and taking it daily.
Wearing UV blocking sunglasses and taking these two eye antioxidants every day can go a long way to protect your sight and keep you independent as you age.
