Abstract

We aimed to study the prevalence of refractive conditions in Singapore teenagers. Grade 9 and 10 students ( n = 946) aged 15–19 years from two secondary schools in Singapore were recruited. The refractive errors of the students’ eyes were measured using non‐cycloplegic autorefraction. Sociodemographic data and information on risk factors for myopia (such as reading and writing) were also obtained using an interviewer‐administered questionnaire. The prevalence of refractive conditions was found to be: myopia [spherical equivalent (SE) at least −0.50 D] – 73.9%, hyperopia (SE at least +0.50 D) – 1.5%, astigmatism (cylinder at least −0.50 D) – 58.7% and anisometropia (SE difference at least 1.00 D) – 11.2%. After adjusting for age and gender, currently doing more than 20.5 h of reading and writing a week was found to be positively associated with myopia [odds ratio 1.12 (95% CI 1.04–1.20, p = 0.003)], as was reading and writing at a close distance and a better educational stream. The prevalence of myopia (73.9%) in Singapore teenagers is high. Current reading and writing habits, reading at close distances and a better educational stream are possible risk factors for myopia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
