Key Highlights:

  • The study aimed to determine whether types of optical correction for refractive error are associated with gender, social class and occupational group in the working population.
  • A cross-sectional investigation was conducted among 86 831 employees in Catalonia aged 16 to 65 years.
  • 46% of participants in the sample were users of optical correction for refractive error.
  • The use of optical correction was more common among female participants than male participants (54.8% and 41.9%, respectively).
  • Non-manual workers were three times more likely to use optical correction than manual workers (OR=3.02; 95% CI=2.82-3.24).
  • Also, individuals in technical, administrative and intellectual occupations were more likely to wear optical correction than unskilled individuals.

Purpose: To determine whether types of optical correction for refractive error are associated with sex, social class, and occupational group in the working population.

Methods: A cross-sectional study was carried out among employees in Catalonia (Spain) aged 16 to 65 years who underwent the Asepeyo Prevention Society health examination in 2009 (86,831 participants: 59,397 men and 27,421 women). The type and purpose of refractive correction used were self-reported, as were sociodemographic variables; visual acuity with habitual correction was also measured. We performed descriptive and logistic regression analyses to evaluate the prevalence and type of correction used for refractive error as a function of age, sex, social class, and occupational group.

Results: Forty-six percent (95% confidence interval [CI] = 45.6 to 46.3) of individuals in this sample were users of optical correction for refractive error. Use of optical correction was more common among women than among men (54.8 and 41.9%, respectively) and especially among women aged 55 to 64 years (91.8%). Nonmanual (class I) workers were three times more likely to use optical correction than manual (class V) workers (odds ratio = 3.02; 95% CI = 2.82 to 3.24). Individuals in technical, administrative, or intellectual occupations were more likely to wear optical correction than unskilled professionals.

Conclusions: The use of visual correction is more prevalent among women than among men, especially in older individuals. The use of optical correction is more common among more advantaged social groups and is associated with particular occupations.
