This study characterized refractive error in a Spanish population, finding emmetropia most common. Myopia prevalence increased with near work, while hyperopia rose with age.

Area of Science:

  • Ophthalmology
  • Refractive Error
  • Population Health

Background:

  • Refractive errors are a significant public health concern.
  • Understanding population-specific refractive error patterns is crucial for eye care.
  • Previous studies have not fully characterized the refractive state of the Spanish population.

Purpose of the Study:

  • To characterize the refractive state of a Spanish population.
  • To determine the prevalence of myopia, hyperopia, and emmetropia.
  • To analyze the influence of age and near work on refractive error.

Main Methods:

  • A cross-sectional study involving 7621 Spanish subjects aged 3 to 93 years.
  • Static retinoscopy and subjective refraction were used for examination.

  • Data analysis focused on prevalence by age group and refractive error type.

    • Main Results:

    • Emmetropia was the most prevalent refractive state (43.2%), decreasing with age.
    • Hyperopia prevalence (35.6%) increased significantly with age.
    • Myopia prevalence (30.1%) was highest in the 30-35 age group, linked to near work.

    Conclusions:

    • Refractive error distribution in the Spanish population is comparable to other global populations.
    • Age and near work are significant factors influencing refractive error prevalence.
    • Findings provide valuable data for public health initiatives and eye care strategies in Spain.
