Why is only one eye myopic when both eyes are used? During the development of the eyes, the refractive state of almost everyone is generally different, and it is rare to find completely consistent. The inconsistency of the refractive state of the two eyes is called anisometropia. Well, do you know that this will have a great impact on the development of the eyes.
Effects of Anisometropia
Easy fatigue
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.
Vision 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.
May cause monocular amblyopia
When a child has anisometropia in both eyes, the eye with smaller refractive power can see things more clearly, while the eye with larger refractive power cannot see things clearly, and the brain cannot fuse the two images with 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 larger refractive power will develop into amblyopia.
