6-causes-of-your-poor-vision-aside-from-agingSure, it’s easy to blame the old age for all of our body changes and health issues, because frankly aging does play a large role in these. But sometimes other factors kick in. Case in point, here are six reasons why your vision is changing that have nothing to do with aging.

6 reasons for your changing vision

You don’t go outside: Studies have shown that more time spent indoors is associated with nearsightedness – which could be prevented by heading outside more often. This is because when we are in the sunlight our pupils become smaller, which reduces visual blur. Furthermore, when our retinas are exposed to the natural sunlight, dopamine is released, which strengthens the eye. So if you find yourself squinting a bit more, maybe you should head outdoors.

You don’t eat berries: If you’re skipping out on berries, you are probably experiencing some vision problems as well. It is well known that berries contain powerful antioxidants, which work to fight free radical damage (a known threat to our vision). Studies have shown that consuming berries can improve night vision in particular and prevent age-related damage.

You’re low on vitamin D: Studies have shown that women who get adequate levels of vitamin D are also 44 percent less likely to develop age-related macular degeneration (AMD). AMD commonly affects adults over 50, so do your part in prevention, and either get out in the sun and soak up some vitamin D, or start eating fatty fish or vitamin D-fortified foods more often.

You went to grad school: Sure, all those years in school may have landed you the job of your dreams, but you may be noticing now that you need glasses more often. Some studies have found a link between too much reading and nearsightedness, because the eye has to work harder. Combine countless hours of studying with lack of sunlight, and you have yourself a combination for poor vision.

You’re always staring at a screen: Practically everyone at any age now has some sort of gadget. Be it a smartphone or a tablet, we are constantly exposing our eyes to the blue light. This can lead to symptoms like blurry vision, nausea, and headaches. If you need to look at a screen for long periods of time, follow the 20-20-20 rule: Every 20 minutes stare at something 20 feet away for 20 seconds.

You have diabetes: Vision problems may be a complication resulting from diabetes. Or, vision problems can even be an early sign of diabetes before you have been formally diagnosed. Diabetes cuts off blood to the retina, causing blurry vision in the beginning and ultimately leading to complete blindness. If you’ve been noticing changes to your vision, your eye doctor will be able to tell if you have diabetes.

As you can see, there are many other factors aside from aging that can contribute to vision problems. The good news is, many of these causes can be modified to protect your vision in the long run.
