Lutein and Zeaxanthin are carotenoids found in the human eye, particularly in the macula, where they play a crucial role in protecting against oxidative stress and filtering harmful blue light. Their presence is associated with a reduced risk of chronic eye diseases, including age-related macular degeneration and cataracts.

Lutein And Zeaxanthin

Carotenoids are a class of pigments naturally found in plants, algae, and photosynthetic bacteria, responsible for the red, yellow, and orange hues in many fruits and vegetables. They play a crucial role in plant health by aiding in photosynthesis and providing antioxidant properties, while also offering potential health benefits to humans, such as supporting eye health and reducing the risk of certain chronic diseases.

Human Eye

The macula is a small, central area of the retina responsible for high-acuity vision, essential for tasks like reading and recognizing faces. Damage to the macula can lead to significant vision loss, as seen in conditions like age-related macular degeneration.

Macula

Oxidative stress is a condition characterized by an imbalance between the production of reactive oxygen species (ROS) and the body's ability to detoxify these harmful byproducts, leading to cellular damage. It is implicated in the pathogenesis of various diseases, including cancer, cardiovascular diseases, and neurodegenerative disorders, highlighting the importance of antioxidants in maintaining cellular health.

Chronic eye diseases

Age-related macular degeneration (AMD) is a leading cause of vision loss in older adults, characterized by the deterioration of the macula, the central part of the retina responsible for sharp vision. While it doesn't lead to complete blindness, AMD significantly impacts the ability to perform everyday tasks that require fine visual detail, such as reading and driving.

Age-related Macular Degeneration

Cataracts are a clouding of the eye's natural lens, leading to a decrease in vision, and are a common cause of blindness worldwide. They can be treated effectively with surgery, which involves replacing the cloudy lens with a clear artificial lens.
