Is hyperopic astigmatism hereditary?

Hyperopic astigmatism is a refractive eye disorder with a high prevalence. Its development is associated with multiple factors and significantly impacts ocular health. Many young men and women suffer from this condition. Besides concerns about their own health, they often worry whether the condition may affect their children. So, is hyperopic astigmatism hereditary?

Is Hyperopic Astigmatism Hereditary?

The presence of hyperopic astigmatism is genetically influenced. If both parents have severe hyperopic astigmatism, their child may inherit a smaller eyeball, resulting in more pronounced hyperopia. In fact, most individuals are born with some degree of hyperopia. As children grow, their eyeballs gradually enlarge, and the hyperopic state progressively normalizes. Typically, children aged five or six may still exhibit mild hyperopia; however, they can see both distant and near objects clearly—a beneficial physiological phenomenon commonly referred to as “hyperopic reserve.” During childhood development, this hyperopic reserve helps delay the onset and progression of myopia.

If diagnosed with hyperopic astigmatism, corrective eyeglasses with appropriate prescription can be prescribed following a comprehensive refraction examination. However, for first-time wearers—especially those requiring relatively high correction—it is advisable to begin with lenses of a lower power to allow gradual adaptation before progressing to fully corrective lenses upon subsequent evaluation. Because the brain has already adapted to the uncorrected astigmatic state, initial lens wear may cause noticeable visual distortion of real-world objects. Additionally, surgical correction may be considered under the guidance of an ophthalmologist.
