Lutein Zeaxanthin and Eye Health

Lutein, zeaxanthin and their effects on eye health

Our eyes are one of the most important sensory organs and play a crucial role in our daily lives. Therefore, it is of great importance to keep our eyes healthy and prevent possible problems. This article is about the role of lutein and zeaxanthin in maintaining and improving eye health.

What are Lutein and Zeaxanthin?

Lutein and zeaxanthin belong to a group of carotenoids called xanthophylls. Carotenoids are naturally occurring pigments found in many plants and organisms. They give fruits and vegetables their bright colors.

Lutein and zeaxanthin are also called “binary stars” because they occur in almost equal amounts in the human eye. They are particularly concentrated in the macula, a small part of the retina. The macula is responsible for central visual acuity and therefore plays a crucial role in activities such as reading, focusing and recognizing details.

The importance of lutein and zeaxanthin for eye health

Protection against oxidative stress

Lutein and zeaxanthin have antioxidant properties that help protect our eyes from oxidative stress. Oxidative stress occurs when an imbalance between free radicals and antioxidants forms in our body. Free radicals are unstable molecules that can arise from a variety of environmental factors such as sunlight, air pollution and smoking.

An adequate supply of lutein and zeaxanthin can reduce the harmful effects of free radicals and therefore help maintain the long-term health of our eyes.

Protection of the retina

Lutein and zeaxanthin play an important role in protecting the retina from harmful blue light. Blue light is emitted by digital screens such as smartphones and computers, as well as sunlight. Long-term exposure to blue light can damage the retina and lead to problems such as macular degeneration.

Through their ability to absorb blue light, lutein and zeaxanthin act as a kind of protective shield for the retina, filtering out harmful blue light and protecting the retina from damage.

Improved visual acuity

Lutein and zeaxanthin can also improve visual acuity. Studies have shown that adequate intake of these two nutrients can lead to better visual function. In particular, the ability to recognize fine details and perceive contrasts can be improved by taking lutein and zeaxanthin.

Protection against age-related macular degeneration

Age-related macular degeneration (AMD) is a common disease associated with aging and primarily affects older people. AMD is a progressive eye disease in which the macula becomes damaged and visual acuity decreases.

Lutein and zeaxanthin have been shown to be effective in reducing the risk and progression of AMD. Through their antioxidant protection and blue light protection, they may help delay the development and progression of AMD.

How to include lutein and zeaxanthin in your diet?

Lutein and zeaxanthin cannot be produced by the body itself and must therefore be consumed through food or supplements. Fortunately, lutein and zeaxanthin are present in many foods, especially green leafy vegetables like spinach, kale, and broccoli.
Other good sources include eggs, avocados and oranges.

It is important to have a balanced diet rich in fruits and vegetables to ensure adequate intake of lutein and zeaxanthin. For those who have difficulty getting enough of these nutrients through their diet, supplements may be an option. However, it is advisable to consult your doctor or nutritionist before taking any supplements.
