What is infantile night blindness?
summary
In our life, there are many friends who are troubled by night blindness. Although such a disease will not cause much harm, it will also have certain effects. We should pay special attention to it at ordinary times. In fact, night blindness is that in the dark environment, the eyesight of the eyes is very poor, so the action will not be so convenient, and we can't see the things in front. Suffering from night blindness has a certain impact on the life of patients. In order to help patients get rid of the trouble caused by night blindness as soon as possible, only better symptomatic treatment can be done. So what is the lack of night blindness?
What is infantile night blindness?
The first one is that night blindness occurs due to the lack of vitamin A in the body. There are cone-shaped cells and slender rod-shaped cells in the retina of our eyes. There is the same light sensing substance in these two cells. If vitamin A is lacking, it will make this substance lose its effect, so we should eat more vegetables and fruits containing vitamin A.
In addition, patients with retinitis pigmentosa often find bilateral night blindness first, and then their vision shrinks, eventually leading to blindness. This problem must prohibit close relatives from getting married. Because there is no good method for the treatment of the disease at present, taking some vitamins and vitamin C and other drugs after diagnosis can delay the disease.
The other is that vitamin A mainly exists in animal liver, various dairy products and fish. The content of vitamin A in shark liver oil and sea fish liver oil is very rich, followed by cow liver, sheep liver and chicken liver. In addition, the yolk of various eggs is also rich in vitamin A.
matters needing attention
Finally, we want to say that patients with night blindness should go to the eye hospital for treatment in time, and friends who usually use their eyes excessively should also pay attention to taking an appropriate amount of vitamin A from the diet in time to help us stay away from the trouble of the disease.
