Carrots have many health benefits and are loved by many – except for one thing. But do they really improve your eyesight? How did the old adage come into existence?

It wasn’t until the 18th century that carrots became commonly known as an aphrodisiac, a tonic for the eyes, and an overall health booster. So why do carrots improve your eyesight?

Carrots And Vitamin A

Carrots, according to studies, are a rich source of a nutrient known as beta carotene. Beta carotene is a compound that gives many red, orange, and yellow plants their deserved colouring. Beta carotene is antioxidant that improves vision through its resistive attack against free radicals in your body.

Free radicals are dangerous compounds that damage body cells and often cause many chronic diseases. Out of these chronic diseases is an eye disease. Beta carotene kills off these compounds and allows for the growth of healthy body cells.

Carrot and Vitamin A

Also, beta carotene, when taken in a large quantity, converts to vitamin A. Vitamin A helps the body cells produce rhodopsin. Rhodopsin is a light-sensitive pigment that gathers in the eye cells to make a better view at night. When your body is short of vitamin A, there is always a problem of night blindness. Vitamin A also protects the cornea, a transparent layer that covers the iris and the pupil.

Vitamin A is also of great help to the eyes as it reduces the risks of cataracts and age-related macular degeneration. To make this possible, vitamin A releases pigments that build protective layers that serve as barricades against bacteria and viruses. These benefits are numerous and should be regarded as eye-friendly measures to help you consume carrots in the right quantities.

Also, coloring in carrots is very vital. It is worthy of note that most colored carrots have lutein. Lutein is a yellow carotenoid pigment, distributed in both plants and animals. Lutein, especially in yellow carrots, help to prevent age-related macular degeneration in your body system, Macular degeneration is a condition of the eyes that blurs the vision.

Indeed, these benefits have asserted the fact and answered the question, “Do carrots improve eyesight!” Of course, this diet is widely recognized but many people may not be aware of its essentiality.

How Many Carrots Do You Need?

According to research, the amount of carrots needed to improve the eyes is determined by the vitality of beta carotene and other vitamin A supplements. To this effect, an estimate of about 12 to 21 molecules of beta carotene in the diet equals just one molecule of vitamin A.

In research carried out in 2005, a study revealed about 4.5 ounces of cooked carrots in six days. So, if you are willing to take carrots, do note that they can be taken boiled, steamed, or raw. Ensure you wash them thoroughly before eating them.

The fact that vitamin A is an eye-friendly supplement is not untrue. However, the intake of carrots should be in moderation. This is because a high intake of beta carotene increases the risk of lung cancer, especially in smokers.

In the same vein, the deficiency in vitamin A is not good either. Deficiency in vitamin A results in xerophthalmia, a condition of eye disease that damages vision and results in night blindness. Also, deficiency in vitamin A, in children and young adults, can result in blindness.

Deficiency in vitamins can also deter the growth of rhodopsin. Rhodopsin is the part of the eyes that views low-light sources such as the moon.
