Lutein

Lutein is one of the carotenoids that make up the retina and macula, and its counterpart, zeaxanthin, is also a carotenoid. Together, the two are responsible for the process of sharp vision.

Vision is a fascinating natural phenomenon. We see everything by the light that enters our eyes, light is sensed by light-sensitive receptors (photoreceptors) on the retina, around which carotenoids are located, which 'lure light to the receptors'. These receptors are located at the end of the sciatic nerve, the electricity generated by the light we perceive then travels up the optic nerve to the brain, where it then becomes the image in our consciousness.

The yellow spot, or macula, is responsible for sharp vision, here light does not encounter any obstacles and can reach the receptors directly, so the image is sharp. The macula contains large amounts of lutein and zeaxanthin.

So lutein is essential for the process of sharp vision. Several studies report that lutein may help prevent age-related macular degeneration. Lutein is also the zeaxanthin, together they are responsible for eye health.

In addition, lutein may also have antioxidant effects, protecting the eye from damage from free radicals. Further strengthening the beneficial effects of lutein on eye health.

Due to its antioxidant effects, it may be beneficial for cardiovascular and nervous system health and may protect the skin against harmful UV-B rays.
