What is Lutein and How it Benefits Your Eyes
Posted by Portions Master on 17th Mar 2023
Lutein is a carotenoid that is essential for maintaining good eye health. This powerful antioxidant is found in high concentrations in the retina of the eye, where it helps to protect the delicate tissues from damage caused by oxidative stress and ultraviolet (UV) light[1]. In this blog, we'll explore the benefits of lutein for the eyes and how it can help maintain good vision as we age.
- Protects Against Age-Related Macular Degeneration (AMD): AMD is a leading cause of blindness in older adults, but lutein has been shown to provide protection against this debilitating condition. By filtering harmful blue light and reducing oxidative stress in the retina, lutein can help reduce the risk of AMD and preserve vision.
- Supports Retinal Health: Lutein is essential for maintaining the health of the retina, the part of the eye that is responsible for transmitting images to the brain. By providing a protective barrier against oxidative stress, lutein helps to keep the retina healthy and functioning properly.
- Improves Visual Acuity: Visual acuity refers to the sharpness and clarity of our vision, and lutein has been shown to improve visual acuity in some studies. By reducing oxidative stress in the retina and filtering harmful blue light, lutein helps to maintain the health of the photoreceptor cells that are responsible for vision.
- Reduces Eye Fatigue: Eye fatigue is a common complaint, particularly among those who spend long hours in front of a computer screen. Lutein has been shown to reduce eye fatigue and improve visual comfort by reducing oxidative stress in the retina and filtering harmful blue light.
- Supports Night Vision: Lutein has been shown to support night vision by reducing oxidative stress in the retina and improving the function of the photoreceptor cells. This can be especially beneficial for older adults, who may experience age-related declines in night vision.
In conclusion, lutein is a vital nutrient for maintaining good eye health. By providing a protective barrier against oxidative stress and harmful blue light, lutein helps to preserve vision, reduce eye fatigue, and support night vision[2]. To ensure adequate intake, it's important to include lutein-rich foods in your diet, such as spinach, kale, collard greens, egg yolks, and corn, or consider taking a lutein supplement such as Portions Master Lutein.
