Wearing Behavior and Eye Length Changes in Children With Myopia Wearing Myopia Control Spectacle Lenses

Resumen breve

The goal of this clinical trial is to learn how children with myopia aged 8 to 15 years move their eyes and heads during near-vision tasks while wearing different spectacle lenses, and if wearing myopia control spectacle lenses for one month is related to change in eye length (axial length). The main questions it aims to answer are: 1. How do eye gaze position and head movement patterns change when children wear the commercially available myopia control spectacle lenses compared with single-vision spectacle lenses? 2. Does wearing myopia control spectacle lenses for one month lead to short-term changes in axial length? This study compares commercially available myopia control spectacle lenses with single-vision spectacle lenses to evaluate differences in eye gaze position, head movement patterns, and axial length. Participants will: * Attend three study visits at the Singapore Polytechnic Optometry Centre. * Wear the assigned study spectacles while performing near-vision tasks. * Have video recordings of their face collected, to evaluate eye and head movements, during the near-vision tasks.
