Can't see clearly at night

At night, our vision is definitely not as clear as during the day, which is a normal phenomenon. Some patients may suffer from night blindness, so they not only cannot see clearly at night, but also become blind. In fact, sometimes we often overuse our eyes without letting them rest, which can also cause blurred vision. So how can we alleviate the problem of not being able to see clearly at night?

1. “Anti-infection vitamins”

Vitamin A can enhance the baby's respiratory and digestive tract's ability to defend against pathogens, and can also enhance the ability of immune cells to produce antibodies, thereby reducing the baby's risk of illness.

Vitamin A is also very important for the formation and maintenance of epithelial cells. If there is a lack of vitamin A, problems such as dry skin, desquamation, and itching will occur.

The earliest discovered function of vitamin A is to maintain visual development. It can promote the formation of photosensitive pigments in visual cells and maintain the integrity of epithelial cells of organs such as the conjunctiva and cornea, thereby maintaining normal visual responses. Severe deficiency can lead to dry eyes and night blindness.

Vitamin A can maintain the normal function of bone cells and promote the differentiation of bone cells, thereby effectively promoting bone growth and development.

4. Improve the body's hematopoietic function

Vitamin A participates in the synthesis of transferrin, ensuring the effective transport of iron and thus preventing anemia.

A large number of medical research results at home and abroad have shown that in countries with vitamin A deficiency, preventive supplementation of vitamin A can effectively reduce the incidence of diarrhea, infectious diseases (such as measles), anemia, night blindness, dry eyes, and reduce child mortality.

How to supplement vitamin A deficiency

Nutritional health care products, increase the intake of nutritional health care products containing vitamin A in appropriate amounts. Nutritional health care products contain high levels of vitamin A and are absorbed quickly, such as cod liver oil.

Eat more fruits and vegetables containing vitamin A, such as apples, loquats, cherries, shepherd's purse, tomatoes, eggplants, etc. In addition, eat more meat containing vitamin A, such as pork, chicken, crab, snails and other foods. - Vitamin deficiency is short-term and can be replenished through dietary adjustment.
