Nutrition during childhood plays an extremely important role in visual development. Therefore, proper and balanced nutrition from natural food sources will prevent potential eye problems, according to the health website Healthline (USA).
Salmon is rich in omega-3 fatty acids, which help maintain and strengthen children's eyesight.
Important nutrients children need to maintain optimal vision include:
Vitamin A and beta-carotene
Foods like carrots, tomatoes, papaya and sweet potatoes are rich in vitamin A and beta-carotene. These nutrients are important for the functioning of the retina, especially supporting the cells that help with night vision.
Vitamin A helps maintain moisture on the surface of the retina, preventing dry eyes and many eye problems that can cause permanent blindness. If the cornea is too dry, it is susceptible to damage, infection, and even blindness.
Lutein and zeaxanthin
Combine green leafy vegetables such as spinach, kale, and watercress, which are rich in antioxidants such as lutein and zeaxanthin. These substances are very beneficial for the macula on the retina, thereby helping children have sharp vision, preventing macular degeneration and reducing the harmful effects of blue light.
In fact, lutein acts as a natural sunscreen, absorbing excess light energy that enters the eye. In addition to leafy greens, foods rich in this antioxidant include berries, eggs, and broccoli.
Omega-3 fatty acids
Omega-3 fatty acids help develop vision and strengthen children's eye health. In the omega-3 fatty acid group, there is DHA, a fatty acid that can maintain the structure and function of the retina. DHA is found in breast milk and some infant formulas. Omega-3 fatty acids are abundant in fatty fish, such as salmon, nuts such as almonds, chia seeds and walnuts.
Vitamin C
Vitamin C is a powerful antioxidant that helps protect the eyes from harmful free radicals and is involved in the regeneration of other antioxidants such as vitamin E. Vitamin C plays an important role in the health of the blood vessels in the eyes and the cornea. Foods rich in vitamin C include oranges, grapefruit, kiwi, and lemons, according to Healthline .
