Night blindness: Not being able to see at night Is night blindness the inability to see at night?

Eat more vitamin A-rich foods such as carrots.

Night blindness, commonly known as "blindfolding", is a medical term that refers to the symptoms of difficulty in moving in dim light or at night when you have difficulty seeing clearly or at all.

Reason 1: Heredity.

In fact, there are many causes of night blindness, and most of them are genetic. Most people are born with night blindness from an early age, which means that they cannot see clearly at night, and these people will inherit it from their parents or grandparents who have night blindness.

Heredity is now considered a relatively large cause of the occurrence of diseases, many major diseases are genetic reasons, this is more difficult to avoid, but some more serious diseases, when pregnant women are pregnant, can be detected, if it is more serious, pregnant women should try to knock out the child, so that the child will not have so many diseases.

Reason 2: Lack of vitamin A

The lack of vitamin A in the body can also cause night blindness, and the acquired cause of night blindness is mainly caused by the lack of vitamin A in the body. The human body usually makes it difficult for the body to absorb vitamin A due to some diseases, or the body itself lacks vitamin A, so the body will cause the retinal rod cells to have no raw materials to synthesize rhodopsin, which is called night blindness. However, this night blindness is temporary, allowing the body to absorb it, and more vitamin A so that the night blindness will disappear.

Because of acquired reasons caused by night blindness, we should usually eat more foods containing more vitamin A in life, such as eggs and animal liver, which contain more vitamin A, and at the same time, we should also add more healthy diets in the diet, eat more nutritious and healthy food, and eat less spicy and greasy junk food, especially for some teenagers, we should eat more of these foods, so as to effectively prevent the appearance of night blindness.

Night blindness is a condition in which vision decreases at night, and there is a genetic component. Its hair is thought to be caused by the lack of a vitamin A, or the lack of an analogue of vitamin A, the light-sensitive ability of rod cells and cones is reduced, and the secretion of rhodopsin or rhodopsin is affected. There is blurred vision, and the most serious state is that you can't see at all.

Severe vision loss at night or in the dark is the main manifestation.

Congenital night blindness has no means, and acquired can generally be.

Acquired vitamin A supplementation can prevent and improve symptoms.

It is mainly caused by retinal rod cell dysfunction.

Hello, generally speaking, if you can't see things clearly at night, it is often night blindness, but this, it is difficult to carry out **, it is recommended to eat lutein, eat a little more animal liver and carrots.

Night blindness is a condition in which you cannot see clearly at night or in a place with low light, or you cannot see at all, and it is caused by a lack of vitamin A.

Night blindness is generally due to congenital genetic genetic diseases caused by rod cell dysplasia, causing clinical symptoms such as vision loss, blurred vision and reduced visual field in dim conditions, in addition, night blindness is also related to vitamin A deficiency, familial hereditary retinal cell dysplasia, primary retinitis pigmentosa and other diseases, when night blindness occurs, vision loss will occur in dim conditions, blurred vision, visual quality changes and visual field significantly narrowing, Therefore, it is necessary to carry out active cause investigation to find the cause of night blindness, and it is generally necessary to carry out genetic testing, retinal fundus vascular examination, and retinal OCT examination to determine whether there is poor developmental function of retinal cells, and trace element determination is required to determine whether vitamin A supplementation is needed for night blindness.

There are many causes of night blindness, and it is important to identify the specific causes. There are currently two possibilities for night blindness, if it is night blindness caused by retinitis pigmentosa, it is hereditary night blindness, due to abnormal development of the X chromosome or gene mutation leading to poor development of rod cells, this kind of night blindness has no way to intervene, and surgery can not solve this kind of night blindness, and can only prevent the night blindness of the next generation through certain genetic screening. At present, there is no particularly effective method, mainly considering complications and existing clinical symptoms, such as wearing optical lenses to correct refractive errors, and concurrent cataract surgery**.

Cornemalacia caused by vitamin A deficiency, night blindness will also appear in the early stage, and it is usually necessary to find the ** that causes vitamin A deficiency, which leads to rod insufficiency and causes decreased night vision. There may also be other causes of night blindness, such as advanced glaucoma, congenital choroidosis, progressive cone rod dystrophy, drug poisoning, etc., because face-to-face diagnosis is not possible, it is recommended that patients seek treatment from the ophthalmology department of the local hospital in time to avoid delaying the condition.

Because the human body lacks vitamin A, the body's poor absorption of vitamin A may be a genetic factor, diabetes may also cause night blindness, eat more foods rich in vitamin A, such as carrots, spinach, Chinese cabbage, tomatoes, you can go to the hospital to check the trace elements, the right medicine.

It is because the body lacks vitamin A, and then it will lead to transient night blindness, you can eat more pork liver carrots to supplement vitamin A.

Night blindness is due to factors such as vitamin deficiencies, eye lesions, genetic factors, decreased resistance, etc.

1. Lack of vitamin AMany night blindness is caused by the lack of vitamin A in the patient's body, so for such patients, the main way is to supplement a large amount of vitamin A, there are many drugs containing vitamin A on the market, but also drugs, after taking it, you can increase the content of vitamin A in the blood, and the symptoms of night blindness will gradually reduce. When taking vitamin A, you should pay attention to follow the doctor's instructions, and do not change the dosage of the substance without permission, as vitamin A may cause poisoning in the body after taking a large amount. 2. The best method of congenital night blindnessAt present, there is no good way to treat congenital night blindness, congenital night blindness will lead to retinitis pigmentosa in patients, and there are some institutions that have some methods for such a situation, mainly to alleviate the gradual aggravation of night blindness, but there is no effective way to completely cure it.

Night blindness is very severe. It is not visible in the evening, which is due to a severe lack of vitamin A, which should be taken under the guidance of a doctor and will soon return to normal.

I can feel this too much. Because I'm just like you. This can indeed be relieved by taking medicine. You need to buy vitamin AD, which is also called cod liver oil. This one is also night blindness.

Night blindness is quite common, there is no medication for this disease**, you can take vitamins to relieve it, or bring a flashlight. I also have mild night blindness, and I usually walk at night with a good flashlight.

Night blindness is caused by a lack of vitamin A and a decrease in cone cells, which is caused by eating less meat, usually eating miscellaneous, don't pick and choose, don't be too frugal, eat meat and vegetarian combinations, reasonable arrangements can be made, and not three can also be self-healing. Medication** Just take vitamin A! FYI!

2.Then night blindness is poor vision or not being able to see at all in the dark or at night. Night blindness, commonly known as "blindfolding", is the so-called night blindness when you can't see clearly at night or in a dimly lit environment, and your own actions are more troublesome.

3.Finally, 200 grams of pork liver, 150 grams of fresh wolfberry leaves, first wash the pork liver and cut it into strips, cook it with wolfberry leaves, drink soup and eat liver, 2 times a day. It can effectively improve the vision of the eyes by treating night blindness and vision loss.

Precautions. Don't worry about night blindness, this is not static, supplement more vitamin A-rich foods in life, and slowly the vision of the eyes can be restored, but in the process of recovery, do not smoke and drink, and maintain good sleep habits.
