Vitamins for Eyesight
Fact: Vitamin A is good for your eyesight. It contains retinoid, a group of compounds that has been proven to have a positive effect on vision, bone growth, and cell division amongst other things. Found in many vegetables and dairy products, Vitamin A is also referred to as anti-infective, because it strengthens the body’s immune system. And if your body is left without Vitamin A you may experience vision problems.
Carrots are perhaps the first primary product that comes to mind when talking about foods that are good for your eyesight. Containing significant amounts of Vitamin A, the foodstuffs below all have a positive effect on your eyesight:
• sweet potatoes
• winter squashes
Why Vitamin A is important for eyesight
Retinol is the form of Vitamin A that plays an important role in your current and future vision. Retinol is a fat-soluble vitamin, closely related to the retinoid family and is furthermore required for the body’s production of rhodopsin, a visual pigment of the retina.
The retina is the light-sensitive part of the eye’s inner layer. Ingesting Vitamin A thus has a rather direct chemical effect on our eyes. Without it, rhodopsin cannot be produced for the retina and our eye’s ability to absorb light will decrease. That is why a lack of Vitamin A often leads to a worsened state of your vision.
Can you lose your eyesight without Vitamin A?
By eating regularly and keeping a healthy diet, you will consume your daily need of Vitamin A. Most of the listed products above are part of our daily food ingestion. However, if you do not eat fruits, vegetables and the occasional fish, lack of vitamins may lead to:
• Nyctalopia – night blindness, due to insufficiencies in the eye’s rhodopsin production for the eye.
• Lowered immune system – without Vitamin A the body’s immune system is weakened increasing the risk of infections and viruses.
In conclusion, Vitamin A is essential for healthy eyesight. But vision deficiency may also be caused by other factors, so getting your eyes checked regularly is strongly advised. An eye examination by a licensed eye doctor will determine the state of your current eyesight and whether or not you will need glasses or contact lenses while consuming your daily dose of Vitamin A.
