Health care effect of lutein on eyes

Abstract: lutein is like the toner in the copier. If the toner in the copier is gone, no image can be copied. In addition, lutein contained in the lens and macular region of the retina can also filter out the blue light in the sunlight to prevent the damage of blue light to the eyes., Lutein is a natural carotenoid in vegetables and fruits. It is a good antioxidant and can protect human cells from free radicals (substances that promote human aging). In human body, it mainly exists in human eyes, skin, serum, cervix, heart, brain and other parts. Lutein is particularly important for protecting human eyes. So, how does lutein act on people’s eyes?, Lutein is mainly distributed in the following two parts of human eyes: (1) retina and macular region; (2) Lens. The center of the retina is the macular region. It is like a copier, gathering many photoreceptor cells. The macular region of the retina can transmit the color and image in the center of the visual field to the brain in time. Lutein is like the toner in the copier. If the toner in the copier is gone, no image can be copied. In addition, lutein contained in the lens and macular region of the retina can also filter out the blue light in the sunlight to prevent the damage of blue light to the eyes., Because blue light will produce a large number of free radicals after entering people’s eyes, causing cataracts or degeneration of the macular region. Therefore, once the human body lacks lutein, there will be aging macular degeneration, cataract, astigmatism, presbyopia, pseudomyopia, visual fatigue and other diseases. Aging macular degeneration and cataract are the two most common eye diseases in the elderly, and they are also the main causes of blindness in the elderly. Thus, lutein is particularly important for protecting human eyes., American nutritionists suggest that adults should take 6 mg of lutein a day. Vegetables containing more lutein include cabbage, spinach, mustard, dark green cauliflower, corn, pumpkin, etc; Fruits containing more lutein include kiwifruit, grape, orange, etc. If people want to get enough lutein, they must eat more lutein rich fruits and vegetables. The study also found that lutein not only protects human eyes, but also plays a role in preventing breast cancer and reducing the incidence rate of heart disease. Therefore, lutein should be supplemented in daily life.,

Aging macular degeneration and cataract are the two most common eye diseases in the elderly, and they are also the main causes of blindness in the elderly. It can be seen that lutein is particularly important to protect people’s eyes.

Therefore, in daily life, we should pay attention to supplement lutein.
