Research published in the journal JAMA Ophthalmology suggests vitamin A may be helpful for children with retinitis pigmentosa, a degenerative eye condition that can lead to loss of sight.
Vitamin A is only one of many nutrients that are essential for healthy eyes. Other important ones include lutein, zeaxanthin, cryptoxanthin, beta carotene, zinc, bioflavonoids, and vitamin C. All these nutrients work together synergistically to maintain healthy eyes.
The blood vessels that supply blood and nourishment to the eyes are made of cells that require the amino acid arginine, for contraction and relaxation, and vitamin C, to ensure optimum collagen production to support blood vessel strength and integrity. While vitamin C is known to reduce ocular pressure in the eyes, thus lowering the risk of glaucoma and loss of sight, its content in the eyes decreases naturally with age and therefore requires additional supplementation.
