The two-year hyperopic reserve reduction of 25 in children refers to the process of progressing to orthokeratology with the development of the eyeball’s eye axis children’s state of hyperopia has been reduced by 25 degrees, which is a normal developmental process.
Under normal circumstances, children from birth to about ten years old, because the eye axis is not fully developed, when looking away from the light through the refractive system and then projected on the retina after the existence of one or two hundred degrees of low hyperopia, belong to the physiological farsightedness, also known as hyperopia reserve. With normal growth and development, this degree of hyperopia will gradually decrease, and children can return to normal vision, which is a normal developmental process.
A normal reserve of hyperopia has a preventive effect on the development of myopia. When a child’s reserve of hyperopia decreases too rapidly or disappears too soon, the child needs to be alerted to the onset of myopia.
Children need regular vision screening to determine if they are developing normal vision. Children with abnormal vision and optometry tests are advised to seek prompt medical attention to evaluate their condition and follow medical advice.
