What can you eat to make your eyes turn black?

Eyes are the most important visual organs of people. Healthy eyes and good vision can bring great convenience to people's survival. There are obvious differences in the shape and color of eyes among different races. For example, the eyes of Oriental people tend to be dark brown, but there are no obvious differences in other aspects. Eye color can change slightly depending on the nature of the food you eat. Let’s take a look at what foods can make your eyeballs black?

Foods containing vitamin A are good for the eyes. When vitamin A is deficient, the eyes' ability to adapt to dark environments decreases, and in severe cases, one is prone to sleepwalking. Vitamin A can also prevent and treat dry eyes. When there is a long-term lack of vitamin A, it can eliminate eye fatigue. Sufficient vitamin A should be consumed every day. The best sources of vitamin A are the livers of various animals, cod liver oil, milk and eggs, plant foods such as carrots, amaranth, spinach, leeks, green peppers, sweet potatoes, and fruits such as oranges, apricots, persimmons, etc.

Liver, egg yolks, and carrots contain a lot of vitamin A. For people who suffer from eye diseases due to vitamin A deficiency, eating some of these foods will definitely help their eyes. Elderly patients can eat more fruits because fruits contain a lot of vitamins C, D, and E, which have certain effects in anti-oxidation and anti-aging. Lycium barbarum has the effect of nourishing the liver and improving eyesight. Long-term consumption is beneficial to eye health. There are laboratories in the United States that are specifically studying the benefits of plants such as wolfberry and ginkgo for the eyes.

Foods containing vitamin C are also good for the eyes. Vitamin C is one of the components of the lens of the eye. If you lack vitamin C, you are prone to cataracts, which is a disease in which the lens becomes cloudy. Therefore, you should pay attention to taking in foods rich in vitamin C in your daily diet. For example, various fresh vegetables and fruits, among which green peppers, cucumbers, cauliflower, Chinese cabbage, fresh dates, raw pears, and oranges have the highest content.

Rich in calcium powder is also good for the eyes, as calcium can eliminate eye strain. For example, beans, green leafy vegetables and dried shrimps are rich in calcium. Cooking methods such as roasted pork ribs soup, cod, and sweet and sour pork ribs can increase the calcium content.
