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 life. It is therefore of great importance to keep our eyes healthy and prevent possible problems. This article is about the role of Lutein and Zeaxanthin when maintaining and improving eye health.

What are lutein and zeaxanthin?

Lutein and Zeaxanthin are part of a group of carotenoids called Xanthophylle. Carotenoids are of course occurring pigments that occur in many plants and organisms. They give fruit and vegetables their bright colors.

lutein and zeaxanthin are also referred to as "double stars" because they occur in the human eye in almost the same amounts. They are particularly concentrated in the macula, a small part of the retina. The Macula is responsible for the central visual acuity and therefore plays a decisive role in activities such as reading, focusing and recognizing details.

The meaning 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 arises when an imbalance forms between free radicals and antioxidants in our body. Free radicals are unstable molecules that can arise in a number of environmental factors such as sunlight, air pollution and smoking.

A sufficient supply of lutein and zeaxanthin can reduce the harmful effects of free radicals and thus help to get the long -term health of our eyes.

protection of the retina

Lutein and Zeaxanthin play an important role in protecting the retina against 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.

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

improved visual acuity

Lutein and Zeaxanthin can also improve visual acuity. Studies have shown that a sufficient supply of these two nutrients can lead to a 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

A age -related macular degeneration (AMD) is a common illness in connection with aging and affects the elderly. AMD is a progressive eye disease in which the macula is damaged and the visual acuity decreases.

lutein and zeaxanthin have proven to be effective in reducing the risk and progression of AMD. With their antioxidant protection and protection against blue light, you can help delay the origin and progression of AMD.

How can you add lutein and zeaxanthin to diet?

Lutein and Zeaxanthin cannot be produced by the body itself and must therefore be absorbed through food or nutritional supplements. Fortunately, Lutein and Zeaxanthin are present in many foods, especially in green leafy vegetables such as spinach, kale and broccoli.
Other good sources are eggs, avocados and oranges.

It is important to have a balanced diet that is rich in fruit and vegetables to ensure a sufficient supply of lutein and zeaxanthin. For those who have difficulty taking up enough of these nutrients through diet, dietary supplements can be an option. However, it is advisable to consult your doctor or nutritionist before taking nutritional supplements.
