What's wrong with myopia and astigmatism?

Many people with myopia will find such a problem when they go to the hospital or optician to get glasses. During the eye test, halos or dotted lines may appear when they look at objects. This is astigmatism. The usual cause of astigmatism is bad posture habits when using mobile phones, such as: playing with mobile phones while lying on your side; playing with mobile phones in insufficient lighting, etc. Astigmatism is like myopia. If you don't pay attention to your own habits, the degree of astigmatism will increase, and it will put a heavy burden on the human eyes, so it is recommended that you protect your eyesight.

If a myopic person does not wear glasses, it is like being sick and not getting injections or taking medicine. The condition will get worse and the degree of myopia will increase. Wearing glasses can not only improve and protect eyesight, but also make study and life more convenient. You will no longer be mistaken for being impolite because you cannot recognize people. Severe refractive errors may cause strabismus and amblyopia if glasses are not fitted in time, which may cause more harm than good.

People with myopia of more than 0.50 degrees should wear glasses. We advocate wearing distance glasses when mainly looking at distant objects, and wearing near glasses when mainly looking at close objects. This not only protects the eyes, but also prevents or slows down the occurrence and development of myopia. Just like a lady puts on makeup before going out and removes makeup and takes care of herself after returning home, using different glasses for distance and near objects can give our eyes more care and protection.

What is astigmatism?

This means that both distant and near objects are blurred, and there are halos around distant objects that emit light or reflect light. In severe cases, there may even be double vision or distorted vision. While saying this, we can use the astigmatism chart to explain: in fact, each line on the chart is the same in thickness and depth, but it looks different to you, which means you have astigmatism; astigmatism is a certain asymmetry in our eye's refractive system. How is astigmatism formed? There are many reasons for astigmatism, mainly genetics and physiological development before the age of 3. The eyeball grows fast and the eyelid grows slowly, which causes uneven growth and development of the cornea. Even when we close our eyes when we sleep, the uneven pressure of the eyelids on the cornea can cause astigmatism.

Which is more serious: myopia, hyperopia or astigmatism?

In fact, the condition of each eye of each person cannot be the same, and it can only be determined after a professional refractive examination; theoretically, there is no difference in severity among the three refractive states, and any severe condition is not good. Why is my vision different in one eye? Unequal vision in both eyes is generally normal and there is no need to worry. There are many reasons why the two eyes have different degrees. For example, eye usage habits and incorrect posture when reading books or newspapers can cause the vision of the two eyes to be unequal. If there is a big difference in vision between the two eyes, you need to pay attention. You can go to a professional eyewear store or hospital for a careful examination to determine the cause. Generally, students have different vision between their two eyes, which is mostly caused by refractive error. Anisometropia can be prevented, but it is best to start wearing glasses for correction before the age of 8, before there is a significant difference in vision between the two eyes.

How can we protect the vision of both eyes to make them the same?

If the difference in vision between the two eyes is caused by anisometropia, it is best to wear appropriate near-sighted glasses before the age of 8, when the person is not yet nearsighted, to gradually eliminate the anisometropia. But after myopia, it is best to maintain the status quo. Because we cannot reduce the degree of the high-degree eye, and we are unwilling to increase the degree of the low-degree eye.
