Effective ways to protect your eyes.

The eye is an extremely delicate organ, and if it is damaged, it is very difficult or even impossible to repair. So we should take good care of our eyes. So, what are some effective ways to protect your eyes?

Prevent trauma. In addition to some mechanical trauma, other things such as chemicals, special light, high temperature and cold, etc., can damage the eyes. Therefore, avoid going to places where there is a lot of wind and sand.

If you are exposed to harmful chemicals at work, you should take precautions. Don't read in bright light, and keep a certain distance when watching TV. Wear protective glasses for electric welding, gas welding, solar eclipse viewing, snow work, etc.

Prevent disease. Many eye diseases are transmitted directly or indirectly, such as trachoma, acute conjunctivitis, etc., if left untreated; Vision slowly deteriorates, leading to blindness. In fact, all systemic diseases can affect the eyes to a greater or lesser extent.

For example, blood diseases, kidney diseases, high blood pressure, and endocrine diseases can affect the eyes, especially tuberculosis, and if they invade the eyes, they can also cause blindness.

Improve bad habits and unreasonable**. For example, if you work or study in a place where the light is too strong or too weak, you are prone to myopia, and rubbing your eyes with your hands is prone to infectious diseases; Drinking alcohol and smoking can cause ophthalmic nerve and vascular lesions. And then there are unreasonable methods, such as believing in quacks and witches, and not using scientific methods, which will bring great damage to the eyes.

Therefore, any eye disease should be consulted by an ophthalmologist**.

Pay attention to nutrition. If there is a lack of nutrients needed in the body in daily food, the body's resistance will be reduced, and it is easy to cause eye diseases. For example, a lack of vitamin A can lead to night blindness and dry eye disease; Lack of vitamin B can lead to retrobulbar optic neuritis.

Having these diseases can also cause blindness. Therefore, we should pay attention to nutrition and eat more foods rich in vitamins A, B and C, such as soy products, eggs, animal heart, liver and kidney, spinach, greens, carrots, Chinese cabbage, etc. and various fruits. Don't be partial to eating, pay attention to the regulation of nutrition, and develop good dietary hygiene habits.
