BSF O Tablet is used for supporting eye health, healthy vision, and ocular well-being. It is formulated with essential nutrients, including lutein, zeaxanthin, mecobalamin, and zinc. Lutein and zeaxanthin act as powerful antioxidants that protect the eyes from oxidative stress and harmful blue light, reducing the risk of age-related macular degeneration and maintaining sharp vision. Mecobalamin supports proper nerve function and helps in the maintenance of a healthy optic nerve, while zinc contributes to normal visual function and supports cellular metabolism in the retina.
