The goal of this observational study was to compare the wearing patterns of spectacles prescribed for myopia control in juvenile wearers.

This unmasked, multi-center, observational study evaluated the wearing patterns of established (use of ≥3 months) juvenile spectacles wearers. It aimed to compare the wearing patterns of spectacles for myopia control between males and females. Wearing pattern were measured via the use of temperature sensors fitted to the sides of the participant's spectacles. Data from the final week of the 1-month study was used for analysis to minimize 'unusual' wear patterns which may have occurred early in the study.

Juvenile participants recruited directly from the patient bases of several UK optometry practices who currently wear spectacles prescribed for myopia

Duration of the study, approximately one month.
