Eye Health

Lutein Vitamins and Eye HealthLutein’s most well-known benefit is for eye health, specifically reducing the risk of age-related macular degeneration. In the human body, lutein can be found in the eye. Within the eye, lutein is highly concentrated in the macula region and is found to a lesser extent in the lens and retina.

Age-related macular degeneration is caused by a lifetime of slow but steady damage to the fragile center of the retina known as the macula. Responsible for central vision and acute sight, this natural deterioration over time can lead to oxidative stress within the macula and eventually cause a loss of central vision. The result is a blurred or completely dark circle in the center of your field of vision, leaving only peripheral vision to see by.

The most common form of age-related macular degeneration is known as Dry AMD. This occurs when a collection of small round fatty deposits collect in the macula region of the retinal macular pigment epithelium beneath the thin macula layer, and the macular pigment thins and dries out, resulting in loss of sight. A less common form is Wet AMD, where blood vessels are formed naturally in the macula. The risk of severe sight loss is much greater with this form of age-related macular degeneration.

Lutein and one other related vitamin is found in the retina, providing a yellowish pigment which protects the macula from the damaging oxidative affects of the sun’s blue-spectrum light. Data suggests a strong correlative link between lutein vitamin intake, macular pigment density and eye health, and the risk of age-related macular degeneration and even the risk of cataracts in the eye.
