What are the dangers of monocular myopia

Now with the popularity of electronic products, the number of people with myopia is increasing and younger. Especially when their children first start to become myopic, many parents take them to get glasses and encounter a difficult problem: when they measure their children's vision, one eye is myopic and the other eye is not. In this case, the child sometimes sees things very clearly and sometimes not so clearly. He feels his eyes are tired after looking for a while, and this can cause dizziness and nausea in the long run. What are the dangers of unilateral myopia?

Generally speaking, during the development of the eyes, there are certain differences in the refractive states of almost everyone, and it is rare to find people who are completely identical. However, if the refractive power of the two eyes differs by more than 200 degrees, it is usually called anisometropia in clinical practice.

If not corrected in time, it may lead to faster vision loss in the "poor eye", monocular amblyopia, exotropia, etc. If there is a refractive difference between the two eyes, it will have a great impact on the development of the eyes.

It is mainly manifested in the following aspects

1. Eyes get tired easily

Anisometropia causes a large difference in the degree of refraction between the two eyes, which can easily lead to consequences such as visual fatigue, dry eyes, tearing, headache, nausea, dizziness, etc. There may also be deviations in judging distances and angles, which can easily endanger one's safety when walking or driving.

2. The vision of the “poor eye” declines faster

There is a principle when using eyes - "use it or lose it", which means that the good eye should be used frequently, and the bad eye should be gradually disused. In this way, the eye with poor vision will experience a phenomenon of myopia increasing rapidly and vision decreasing rapidly.

3. Can cause monocular amblyopia

When a child's two eyes have refractive differences, the eye with a smaller refractive power can see things more clearly, while the eye with a larger refractive power cannot see things clearly, and the brain cannot merge the two images of different clarity into one. At this time, the brain will command the eye with smaller refractive power to work and inhibit the eye with larger refractive power from working. Over time, the eye with a larger refractive power will develop into amblyopia.

4. Can cause monocular exotropia

As mentioned above, when a child's two eyes have anisometropia, the visual development of the eye with poorer vision will also be inhibited. If it is not effectively treated, the eye with poorer vision may develop into exotropia over time.

How to prevent correction discrepancies?

In daily life, do not tilt your head when looking at close objects. The object should be placed in front of both eyes and both eyes should look at it at the same time. Habitual side sleeping and incorrect pen-holding posture may lead to different degrees of anisometropia, which need to be corrected in time.
