Protect Your Eyesight with This Little Known Nutrient

eye-checkupThere's an existing nutrient that is incredibly important to your eye health. However, odds are you've probably never heard of it.

The nutrient is called zeaxanthin (pronounced Zee-ah-zan-thun). The antioxidant, along with lutein, is found in the back of the eye as a component of the macular pigment.

Zeaxanthin and lutein are antioxidants that protect against light-induced oxidative stress, functioning like "internal sunglasses". In nature, lutein and zeaxanthin appear to absorb excess light energy to prevent damage to plants from too much sunlight, especially from high-energy light rays called blue light.

Increasing zeaxanthin intake helps maintain visual performance over the long term, including:

  • Enhanced visual acuity - improved vision in fine detail situations like needlepoint or reading in low light situations.
  • Reduced glare recovery time - faster recovery from temporary "blindness" caused by high intensity lighting, such as automobile or stadium lights.
  • Improved contrast sensitivity - ability to discern objects from their background, e.g., seeing a white golf ball or baseball clearly against a light blue sky.
  • Diminished light sensitivity and visual discomfort - less visual discomfort in sunlight or when exposed to bright light.
  • Increased visual processing speed - seeing an object more clearly, enabling improved processing speed and reaction time.

A study published in the American Journal of Epidemiology, found that higher levels of lutein and zeaxanthin in the diet are associated with a lower incidence of Age-related Macular Degeneration (AMD). AMD destroys central vision and is the leading cause of severe vision loss in adults over the age of 55. There is no current cure for AMD and the effects are irreversible.

Eating turnip greens and cooked spinach, which contain zeaxanthin, quitting smoking, incorporating a healthy diet and having a healthy body mass index are ways to reduce the risk of AMD. Incorporating a supplement with lutein and zeaxanthin, like EyePromise, can also help protect as well as preserve vision. (BPT)
