Hyperopia in children may be caused by normal development, genetic factors, developmental abnormalities and so on. 1. Normal development: Most children are born with a certain degree of hyperopia, which is caused by the shortness of their eye axes, and is physiological hyperopia. With growth and development, the eyeballs gradually increase in size and the eye axes become longer, the degree of hyperopia will gradually decrease, and the patient may regain normal vision, or may develop into myopia. 2. Genetic factors: If there is a genetic history of hyperopia in the family for several generations, it may be passed on to the next generation through genes, resulting in the development of pathologic hyperopia in children, and the degree of hyperopia in children is much higher than that of their peers. 3. Others: If a child is born with small eyeballs, hyperopia can also occur because the eye axis is too short. It is recommended that children with hyperopia should consult a doctor in time to evaluate their condition and be treated under the guidance of the hospital.
