Taking Fish Oil Tablets Improves ‘Night Vision’


A new study has found that fish oil supplements can significantly improve ‘night vision’.


The ability to see in low-light conditions, and the health and functioning of our eyes in general, is greatly affected by nutritional status.

Nutrients such as lutein, zeaxanthin, cryptoxanthin, beta carotene, zinc, bioflavonoids, and vitamins A and C are essential for proper functioning of cells in the retina and macula of the eye. Similarly, nutrients such as the amino acid cysteine, vitamins C and E, and lipoic acid work together synergistically to protect the functions of the optic nerve.

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. Vitamin C is known to reduce ocular pressure in the eyes. However, its content in the eyes decreases naturally with age. For optimum maintenance of sight, vitamin C supplementation is therefore necessary.

A study published in 2016 found that high levels of vitamin C may protect against progression of cataracts. The researchers found that people with higher intakes of vitamin C were associated with a 33 percent reduction in the risk of cataract progression. They also had ‘clearer’ lenses than those who consumed lower levels.
