Ensures Healthy Eyes: Vitamin A can aid in improving vision. It enables your eyes to adjust to light changes, keeps the eyes moist, and also improves night vision. It can prevent many conditions like dry eyes as well. It helps in the formation of visual purple in the eyes, which can improve the vision of weak eyes.
Vitamin A is found in fish oil, salmon, carrots, dairy products, spinach, and broccoli. Since it promotes normal keratinization (the turnover of skin cells), it helps with conditions such as acne, eczema, and psoriasis.Without it, skin becomes extremely dry and dull.n skin products, vitamin A is described as an antioxidant that protects the skin against photoaging by fortifying each cell against damage by exposure to free-radicals.
