Is it normal for a six-year-old boy to have a right eye of 1.2 and a left eye of 0.8?

In general, a six-year-old boy with an abnormal right eye of 1.2 and a left eye of 0.8 is considered to have a refractive error, and the left eye may have a refractive error.
Children’s visual function is a process that requires continuous development and improvement, and they have normal visual acuity at about 3 years of age. Currently, visual acuity greater than or equal to 1.0 is considered to be normal, so a six-year-old child with 1.2 in the right eye and 0.8 in the left eye is considered to be abnormal, and refractive error is considered to be the most common cause, meaning that the refractive states of the two eyes are different in nature or degree.
This condition may be caused by an imbalance in the development of the eye axes. In addition, 0.8 in the left eye is considered to be a refractive error, which can be categorized as myopia, hyperopia and astigmatism, all of which are related to heredity, congenital lens dysplasia, and long-term incorrect eye posture.
When a six-year-old boy is found to have different vision in both eyes, he needs to strengthen his daily life management, improve his bad eye habits and go to the hospital for regular eye checkups.
