Abstract: the phenomenon that one eye is in the state of myopia and the other eye is in the state of hyperopia can occur, which is the result of people’s growth and development. This condition is called anisometropia., Myopia refers to that when the eye is in a relaxed state of adjustment, the focus of the parallel light after refraction by the refractive system of the eye falls in front of the retina. In short, it means seeing near but not far. Hyperopia is that parallel light enters the eye and forms a focus after the retina. External objects can not form a clear image in the retina. On the contrary to myopia, hyperopia can not see near, and some patients with high hyperopia can not see far and near. Seeing this, some readers may have the idea: can hyperopia and myopia occur in one eye at the same time? In fact, it is possible., Mixed astigmatism, under normal circumstances, it is impossible to have myopia and hyperopia in the same eye at the same time, unless it is suffering from mixed astigmatism.
Myopia refers to that when the eye is in a relaxed state of adjustment, the focus of parallel light after refraction by the refractive system of the eye falls in front of the retina. In short, it means seeing near but not far. Hyperopia is that parallel light enters the eye and forms a focus after the retina. External objects can not form a clear image in the retina. On the contrary to myopia, hyperopia can not see near, and some patients with high hyperopia can not see far and near. Seeing this, some readers may have the idea: can hyperopia and myopia occur in one eye at the same time? In fact, it is possible.
Mixed astigmatism
Under normal circumstances, it is impossible to have myopia and hyperopia in the same eye at the same time, except for mixed astigmatism. Mixed astigmatism is the combination of simple myopia astigmatism and simple hyperopia astigmatism. It refers to two meridian lines at right angles to each other, one is hyperopia and the other is myopia. When parallel light enters the eye, the focus of the two meridians is in the front and back of the retina. The disease can be detected by optometry and needs to be corrected by wearing glasses to avoid delaying the disease.
Anisometropia
In addition to the above situation, there is another possibility that one eye is hyperopia and the other eye is myopia. This situation is not difficult to understand. The development size of the ocular axis of the two eyes is different. For example, the degree of myopia of the two eyes in many people will be inconsistent. In addition, there will be cases where one eye is normal and one eye is short-sighted or hyperopia. For example, some people will have a deviation in the size of their two feet, and sometimes the length of their arms will be different.
The phenomenon that one eye is in the state of myopia and the other eye is in the state of hyperopia can occur, which is the result of people’s growth and development. This condition is called anisometropia. Anisometropia is more harmful than ordinary myopia and hyperopia. If it is found, it should be corrected with glasses in time. Due to the large degree gap, amblyopia will be formed if it is not corrected in time. If children grow up and can wear contact lenses, they can choose contact lenses to correct, so it is not easy to form parallax. Be sure to pay attention to hygiene when wearing it and take it off in time at night. It is not recommended to choose beautiful pupil. Normal transparent color is the best.
Hyperopia may also become myopia
In terms of eye structure, myopia can not develop into hyperopia, but it is also possible to develop from hyperopia into myopia. Children with congenital hyperopia will gradually elongate their ocular axis with growth and development, and form myopia over time, but most of them with high hyperopia cannot develop into myopia. No matter which state, we should go to the hospital in time and correct our eyesight scientifically under the guidance of doctors.
Suggestion: check the eye health of children at the age of 3.
Many children will have ametropia, so parents are required to find and treat them in time. As parents, we should timely observe the situation of children’s vision. At the same time, when the child is about 3 years old, parents should take the child to the hospital for eye examination, so as to find the condition as soon as possible. Whether it is myopia, hyperopia, mixed astigmatism or anisometropia, the sooner the better. If it is not corrected in time, it is easy to form amblyopia.
