What reason is left eye hyperopia?

summary

We call the regulation of the positive field of vision as physiological regulation; The regulation used in hyperopia is called non physiological regulation. Because the imaging of hyperopic eye itself is behind the retina, the hyperopic eye needs to adjust the lens constantly to see clearly, which is very easy to fatigue and does great harm in the long term. What reason is left eye hyperopia? Let's talk about it

What reason is left eye hyperopia?

Hyperopia is the most common axial hyperopia, that is, the anterior axis of the eye is short. This is a refractive anomaly. In the main axis, the average is about 17.3 mm. From the angle of the length of the eye axis, almost all of them are hyperopia. In infants, hyperopia is physiological, so to speak. After that, as the baby's body develops, the front axle of the eye grows slowly and remains until adulthood, when the eye should be at or near the surface of the face.

Generally speaking, the axial length of human presbyopia is not very short, rarely more than 2 mm. According to the optical calculation of eye curvature, every 1 mm shortening represents a change of about 3 days, and hyperopia over 6 days is rare. But also very far sighted, some people's eyes, although not combined with other lesions, will also be up to 24 days. Pathological hair, abnormal clothing, such as small eyes, hyperopia degree even more than 24 days.

In the process of eye development of some people, due to the internal influence (heredity) and external environment, the eye stops developing and cannot reach the normal axial length. Therefore, the axial length of adults or infants is called axial visionary. The short front axle of the eye is also seen under pathological conditions.

matters needing attention

Parents should avoid a pair of glasses. In the early postnatal period of normal children, the degree of hyperopia gradually decreases due to shorter axial length, more rational life and farsightedness, and eye development in the future. Until the adult development changes, so children's hyperopia wearing lens correction must reduce the degree of glasses year by year, must not wear a pair of glasses for a long time, or you will make hyperopia correction, increase the development of the eye obstacles, slow natural healing of physiological hyperopia. According to the reasons that may lead to hyperopia, parents should pay more attention to keep your child away from hyperopia.
