Doctors Won’t Tell You THIS Fix for Dry Eyes

I can always tell when someone is dealing with dry eyes.

There are three tell-tale signs.

Their eyes are red and irritated. They have a habit of rubbing them. And they tend to blink a lot.

Dry eyes often cause stinging, burning, or itching—and sometimes it feels like you’ve got sand or grit under your lid.

Dry eye cases have skyrocketed in recent years. But I have a surprisingly simple way to fight back…

The solution? Step outside.

Like so many other modern ailments, dry eyes are most often caused by today’s lifestyle.

I can guarantee you our ancestors weren’t plagued by dry eyes. That’s because they didn’t lock themselves indoors all day, staring at screens emitting blue light. They got plenty of sunlight, and their eyes functioned as nature intended, constantly shifting between near and far objects.

Today, incredibly, nearly half of all adults are affected by dry eyes.

To find out why, researchers analyzed data on 450 patients with dry eyes and 900 controls. They found that over 10 years, greater exposure to green space was associated with a significantly lower risk of dry eyes.

I find the term “green space” amusing. It technically refers to designated areas of grass and trees in an urban environment.

But the fact that we even need designated “green space” areas shows just how far we’ve drifted from nature.

Typically, people with dry eye have a smaller amount of tear meniscus. This is the fluid that collects in the lower eyelid, and it’s vital for proper tear production.

The study found that spending more time outdoors boosted tear meniscus size—proof that simply being outside goes straight to the root of the problem.

And I’ve found that to true for FAR more than just dry eyes.

Some problems are complicated. This one isn’t.

Head outside for better eye health—and better health in general.

P.S. Do THIS every 20 minute to STOP digital eye strain.
