One eye is myopic, one eye is not myopic, is it necessary to correct?

Abstract: Generally speaking, in the process of eye development, there are some differences in the refractive state of almost all people, and it is very rare to have complete consistency. However, if the diopter difference of both eyes is more than 250 degrees, it can usually be called anisometropia in clinic.

many myopic patients are confused about this matter: one eye is myopic and the other eye is not myopic. Is it necessary to correct it? Let’s say, you can see clearly without glasses, but sometimes your eyes are easy to be tired, and even a little dizzy and disgusting… What should I do?

generally speaking, in the process of eye development, there are some differences in the refractive state of almost all people, and the completely consistent ones are rare. However, if the diopter difference of both eyes is more than 250 degrees, it can usually be called anisometropia in clinic. If

and

are not corrected in time, it can lead to faster visual loss of “poor eyes”, monocular amblyopia, exotropia, etc. if there is anisometropia in both eyes, it will have a great impact on the development of their eyes.

and

are mainly manifested in the following aspects

and

1. Eyes are prone to fatigue.

and

have anisometropia, resulting in large differences in binocular power, which is easy to lead to visual fatigue, dry eyes, tears, headache, nausea, dizziness and other consequences, and there may be deviations in judging distance and angle. When walking or driving, Easy to endanger their own safety.

and

2. The eyesight of “poor eyes” decreases faster.

and

eyes have a principle of “use in advance and discard in return”, that is, good eyes are often used, and the bad eye is gradually abandoned. In this way, the eyesight of eyes with poor eyesight will increase rapidly and the eyesight will decrease rapidly.

3. It can lead to monocular amblyopia

when the child’s two eyes have anisometropia, the eyes with small refractive power will see things clearly, while the eyes with large refractive power can’t see things clearly, and the brain can’t integrate two objects with different clarity into one. At this time, the brain will command the eye with low refractive power to work and inhibit the eye with high refractive power to work. Over time, the eye with large refractive power will develop into amblyopia.

4. Monocular exotropia

as mentioned above, when the child’s two eyes have anisometropia, the visual development of the eye with poor vision will also be inhibited. If there is no effective treatment, the eye with poor vision may develop into exotropia over time.

how to correct anisometropia

for anisometropia, the most commonly used correction methods are wearing frame glasses, contact lenses and eye training.

for teenagers, wearing frame glasses is very effective. So, We usually give children with anisometropia full correction or close to full correction as far as possible (i.e. corrected vision reaches 1.0), supplemented by binocular vision improvement training and covering treatment. Especially children under 12 years old should correct all ametropia as soon as possible, consolidate their binocular vision, and focus on the emergence and development of strabismus and amblyopia.

For adults, as well as people with alternating vision and visual fatigue, they also need to be fully corrected.

and

can not be fully corrected if they are elderly and have no visual fatigue. How can

and

prevent and correct uneven?

in daily life, do not look sideways when looking at near objects. The objects should be placed in front of both eyes and watched at the same time. Habitual side sleeping and incorrect pen holding posture may lead to different degrees of anisometropia, which needs to be corrected in time. In addition, vitamin A, lutein and anthocyanin can be supplemented appropriately to help alleviate visual fatigue and protect eyes.
