The 3-Minute Light Trick for Better Eyesight

Have you noticed that your eyesight isn’t as sharp as it used to be?

One of the earliest signs of age-linked vision changes is when you find yourself squinting at the small print on bottles, menus, and other close-by objects. That’s when reading glasses become a permanent accessory.

But you could also develop dry eyes, difficultly seeing clearly in low light, or trouble distinguishing between similar colors.

And of course, aging ramps up your risk for eye diseases, like macular degeneration, glaucoma, or cataracts.

It’s clear that aging is terrible for your eyes—but it doesn’t have to be.

Scientists have identified a novel way to protect aging eyes, and it couldn’t be easier.

Exciting new research sheds light on the healing power of morning sunlight.

Researchers exposed volunteers to 15 minutes of long wavelength red light (830-860 nanometers), and three significant things occurred:

1. The red light penetrated to organs deep within the body.
2. Energy production in the body increased.
3. Visual function improved within 24 hours.

Plenty of research has already shown that red light can promote healing. This study was different because it measured the red light’s ability to actually penetrate deep into the body.

There, these longer wavelengths of red light improved the function of mitochondria, which are the power plants in your cells that convert food into energy.

This significantly affects your vision because your outer retina contains the highest density of mitochondria in your body.

In fact, mitochondria dysfunction is one of the primary reasons that your vision suffers so much with age. Which means supporting them—especially with red light—can go a long way toward preserving your eyesight.

What’s more, the study proved that clothing doesn’t stop red light from penetrating the skin and that the same beneficial effects are experienced when light is blocked from the eyes.

Interestingly, a related study showed that just three minutes of morning sun can boost mitochondrial function a full week—improving eyesight in the process.

But timing matters when it comes to harnessing the power of ultrared light. Studies show that while morning sunlight improves vision, afternoon sunlight doesn’t.

That’s because red light is most abundant during sunrise and sunset when the sun is at a lower angle in the sky.

The bottom line is when you make watching the sunrise a part of your daily routine, you’re embracing the easiest, cheapest, and fastest way to boost your vision—and overall health.

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