Are We Being Overexposed to Blue Light?

Overexposed to Blue Light?

Based on the opinion from a recent Nordic Naturals educational article, for lots of us the answer is yes, we are overexposed to to blue light .

Why?

This is because cell phones, TV, computers and LEDs have increased our exposure to blue light a lot.

What is Blue Light?

Sunlight is made up of a complete spectrum of colors. Each of the colors has a specific wavelength. When the wave lengths are longer they are less energetic but when they are shorter the wave lengths are more energetic.

Blue light happens to be one of the shortest and most energetic wave lengths.

It has a very rapid up-and-down action and this causes a flickering effect which in turn can strain the eyes.

What happens to our eyes as a result of blue light overexposure?

Overexposure together with the eye’s inability to block out blue light efficiently can lead to blue light damage.

The cornea and lens do block harmful UV light however blue light is not blocked and it passes through to the retina which is light sensitive.

In the short term this type of exposure may lead to blurred vision, dry eyes, eye fatigue, strains, and even headaches.

Then, long term exposure may result in retinal damage and other age-related eye problems.
Nutrients that provide Natural Defense.

Fortunately, lutein and zeaxanthin naturally defend the eyes by filtering out blue light.

Lutein and zeaxanthin are what we refer to as carotenoids.

  • They are found in high concentrations in the eye’s macula.
  • They give the macula it’s yellow color. It’s the macular pigment that is able to be an optical filter that protects against light and also aids in easing the damage that is caused by blue-light*.

Omega-3 EPA and DHA also play an important role in eye health.

EPA helps to reduce excessive cellular stress and inflammation, which may be found with eye dryness*.

DHA supports the production of meibum, which is a lipid-rich secretion that contributes to health of the ocular surface.*
