Lutein and zeaxanthin are carotenoids found in vegetables and fruits. They may act as antioxidants, protecting cells against the damaging effects of free radicals and may help support healthy eyes and vision. Most of us are unaware of how high-energy blue light affects eye health. High-energy blue light is emitted from a variety of sources including digital devices (e.g. computers/laptops, smartphones, television screens etc.) and artificial indoor lighting.
