Purpose:
To assess the patterns and predictors of glasses wear in a 2-year school-based study.
Methods:
Second and third graders underwent an eye examination at school. Two pairs of glasses were provided if they met prescribing criteria. Replacements were provided as needed. Students received follow-up examinations and completed survey questionnaires during the same and the following academic year.
Results:
Of the 197 students prescribed glasses who completed year 1 follow-up, 172 (87%), were observed to still be wearing glasses. However, less than two-thirds of students reported wearing glasses as prescribed (eg full-time if prescribed full-time). Most students, 175 (89%), reported being happy with their glasses and 135 (69%) reported improvement in vision. Thirty-nine students (20%) reported being teased about their glasses. Replacement glasses were required by 136 students (66%). Refractive error was not associated with likelihood of requiring replacement. Being observed wearing glasses correlated with parent (OR = 4.2; 95% CI, 1.2-15.0) and teacher reminders (OR = 6.4; 95% CI, 1.5-28.4) in year 2.
Conclusions:
Most children continued to wear glasses during follow-up, yet not always as prescribed. A substantial proportion of students required replacements, underscoring the importance of school-based programs developing mechanisms to monitor eyeglasses usage and mechanisms to replace lost or broken pairs.
