Deterioration of macular pigment can lead to macular degeneration and eventually cause permanent loss of vision.
How does lutein improve vision?
Among all the wavelengths of light, blue light has the highest energy wavelength. It can penetrate directly through the lens into the retina, and damage the cells. However, blue light exists everywhere around us. It can be from the sunlight, artificial lights and digital devices screens. People nowadays have increased screen time for working and entertainment purposes. Exposure of too many blue lights to eyes can damage the light-sensitive cells in retina.
Lutein plays an important role in blue light filtering by absorbing the blue lights that penetrate into the eye. Other than that, its antioxidant properties protect the damage from reactive oxygen species (ROS) resulting from blue light. Previous study observed that increased intake of lutein per day significantly reduced the risk of age-related Macular Degeneration (AMD) for 57%.
