They say that eyes are the windows to the soul, but when your eyes are no longer bright, can you still see the beautiful world outside? Therefore, it is especially important to protect your eyes and provide them with enough nutrition. Let's introduce several foods that are beneficial for the eyes.
1. Carrots fight night blindness
Carrots, the most well-known eye-protecting food, contain a large amount of beta-carotene, which can be converted into vitamin A in the body, hence being called "vitamin A precursor". Vitamin A plays an important role in the formation of human vision. It participates in the synthesis of visual purple in the retina. If there is a deficiency of vitamin A, the ability of the eyes to adapt to dark environments will decrease, and in severe cases, it may lead to night blindness.
When consuming carrots, it is important to note that beta-carotene is a fat-soluble vitamin and needs to be absorbed by the body when combined with oil, so it is best to cook them.
2. Use your eyes frequently and eat more yellow corn
When we are young, we often use our eyes, but prolonged periods of work and reading can harm our eyes. As a result of eye aging, macular degeneration can occur, leading to vision loss. At this time, the lutein found in yellow corn has a strong antioxidant effect and can ensure our vision.
It is important to note that only yellow corn contains lutein, while white corn does not. Therefore, for people who frequently use their eyes, such as writers, drivers, students, and editors, it is good for their vision to eat more yellow corn.
3. Egg yolks make your eyes brighter
Lutein and zeaxanthin in egg yolks are recognized as nutrients that are good for the eyes and can make the eyes brighter. These two nutrients can reduce the damage of ultraviolet rays to the eyes, delay eye aging, and prevent diseases such as age-related macular degeneration and cataracts.
For patients with high cholesterol, high blood lipids, and high blood pressure, it is recommended not to consume too much egg yolk at once. Half to one egg yolk per day is sufficient.
4. Spinach prevents eye aging
A recent study by the University of Manchester in the UK confirmed that spinach is one of the best sources of lutein, and lutein is very effective in preventing "age-related macular degeneration" caused by eye aging.
Abundant lutein in dark green leafy vegetables like spinach is very helpful in preventing cataracts. According to research, green leafy vegetables are also good sources of vitamin B2 and beta-carotene. When there is enough vitamin B2 in the body, the eyes are less likely to have bloodshot appearance. Beta-carotene can be converted into vitamin A in the body, preventing diseases such as "dry eye."
In addition, spinach, which is rich in potassium, calcium, and magnesium, can help strengthen the elasticity of the eye muscles and reduce the occurrence of myopia. It is well known that people who lack calcium have poor eye elasticity and are prone to elongation of the eyeball.
5. Sweet potatoes for eye fatigue
As people age, their eyes are prone to fatigue, sometimes feeling pain, unable to open their eyes, and experiencing declining vision. "The eyes are the mirror of the internal organs." Eye problems are signals of the decline and aging of internal organs, especially the liver and kidney. Therefore, to improve the function of the eyes, it is a prerequisite to restore the function of internal organs.
Warm reminder: When using a computer, reading, or looking at a newspaper, it is best to take a 5-minute break every 30 minutes, stand up and move around, or look outside the window to shift the focus from close-range to far-range. The distance between the computer screen and the eyes should not be less than 30 cm, and using radiation-certified glasses can avoid the damage of radiation to the eyes.
