Summary

High educational demands are linked to significant refractive errors like myopia and hyperopia in young adults. Many myopic students received corrective lenses later in life, indicating potential delays in vision correction.

Area of Science:

  • Ophthalmology
  • Optometry
  • Public Health

Background:

  • Refractive errors are common vision impairments.
  • High educational demands, particularly extensive reading, may influence refractive error development.
  • Understanding refractive error prevalence in young adults is crucial for early intervention.

Purpose of the Study:

  • To determine the prevalence of refractive errors (myopia and hyperopia) in first-year engineering students.
  • To investigate the relationship between refractive errors and factors like age of first correction and body height.
  • To assess the impact of high educational demands on vision health in young adults.

Main Methods:

  • Subjective refraction was performed on 224 first-year engineering students (mean age 20.6 years).
  • Prevalence rates for myopia and hyperopia were calculated for right eye, left eye, and both eyes.
  • Statistical analysis was used to compare refractive errors between genders and correlate with body height and intraocular pressure.

Main Results:

  • A high prevalence of myopia (42.9% in both eyes) and hyperopia (23.2% in both eyes) was detected.
  • The mean refractive error was -0.7 D in both eyes.
  • Over half of myopic students received their first corrective lenses at age 16 or later; no significant gender difference in myopia prevalence was observed.

Conclusions:

  • Young adults in demanding academic programs exhibit significant rates of myopia and hyperopia.
  • Delayed prescription of corrective lenses in myopic students warrants further investigation.
  • While body height showed a significant difference in women, intraocular pressure was not significantly related to refractive errors.
