Vitamin A is a critical nutrient when it comes to eyesight. Not only does vitamin A help you see, it also helps protect your eyes from infection and produces pigment in the retina of your eye. Vitamin A is useful in a variety of other ways because it is also an antioxidant, which helps protect and heal your body, and it helps maintain your skin, teeth, mucus membranes and soft tissue.
Vitamin A promotes good vision, according to MedlinePlus. Vitamin A is especially important for seeing in the dark or in poorly lit areas. Without vitamin A, you wouldn’t be able to establish a wide array of colors because it helps your eyes distinguish colors such as bright orange or dark purple. Vitamin A may even help prevent certain eye diseases that cause severe vision loss among young people, according to All About Vision. One of the first and most common signs of a vitamin A deficiency is night blindness and vision loss.
Vitamin A also helps combat healthy eyes for a few different reasons. Vitamin A is an antioxidant, which helps fight free radicals that could cause potential eye infections, according to All About Vision. Vitamin A also protects the mucus membranes that cover your eyes, which helps decrease the risk of infection by acting as a barrier to viruses and bacteria.
Dry Eyes and Other Eye Conditions
Vitamin A drops can help cure dry eye syndrome and help lubricate and protect the eyes. According to All About Vision, eye drops formulated with vitamin A are just as effective at treating dry eyes as expensive prescription eye drops. Vitamin A drops can also help treat certain types of eye inflammation, such as superior limbic keratoconjunctivitis. Ongoing research is being conducted to determine and prove the effectiveness of vitamin A to treat conditions such as retinitis pigmentosa, peripheral vision loss, Stargardt’s disease and other conditions.
Vitamin A Dosage
Without enough vitamin A, you could develop a vitamin A deficiency. A deficiency of vitamin A could lead to corneal ulcers, clouding of the front of the eye and damage to the retina. Vitamin A is typically found in colorful foods such as cantaloupe, watermelon, yellow and red peppers, carrots, spinach and sweet potatoes. Women need 700 mcg of vitamin A each day while men require 900 mcg of vitamin A. The recommended daily allowance for children will vary upon age. Children ages 1 to 3 need 300 mcg per day, children 4 to 8 require 400 mcg per day and children 9 to 13 need 600 mcg per day. Always check with your doctor or your child’s pediatrician before taking any vitamin supplements to ensure that your need is within the recommended guidelines.
