Amblyopia is not usually hereditary, but having a parent with amblyopia is a risk factor, and the causes of amblyopia can be inherited, such as severe refractive errors and other factors. Amblyopia is defined as best-corrected visual acuity that is lower than normal for the same age group, usually in the absence of organic pathology of the eye. The causes of amblyopia include strabismus, high refractive error, refractive error, form deprivation and other factors that affect the normal development of the eye and lead to eventual impairment of vision development, so amblyopia is not usually hereditary. However, these factors affecting vision development may be hereditary. For example, high refractive errors, including high myopia and hyperopia, may be hereditary, resulting in impaired vision development and amblyopia in the fetus. When both parents suffer from amblyopia, you need to pay attention to the development of your child’s vision and go to the hospital for regular vision checkups to prevent amblyopia from developing.
