Family history of myopia is not related to the final amount of refractive error in low and moderate myopia.

Background: Previous research has found an association between family history and presence of myopia. It is possible that family history also could be related to the final amount of refractive error developed. If that were true, then family history of myopia could have predictive value for the amount of refractive error a child or young adult would develop after first lens prescription.
