Importance: Early onset of myopia increases the risk of high myopia, which can lead to irreversible retinal damage and even loss of central vision.
Objective: To investigate the efficacy and safety of naked-eye 3-dimensional vision training (NVT) in preventing the progression of myopia in children.
Design, Setting, And Participants: This randomized clinical trial was conducted in 3 hospitals from May 25, 2022, to February 24, 2023.
Purpose: To validate a novel wearable device that can measure both viewing distance and light exposure, Clouclip, and compare questionnaire estimates regarding near-work and outdoor time with the objective measures obtained using Clouclip.
Methods: Fifteen Clouclips were selected to measure different distances and levels of illuminance. With each Clouclip, five measurements at different distances and light intensities were measured and recorded.

Aim: To reassess the association between near work, outdoor exposure and myopia in children through an objective approach.
Methods: Eighty-six children (10.13±0.
Introduction: The study aimed to determine the effectiveness of an intervention for unhealthy visual behaviors of school-age children using a wearable device (Clouclip).
Method: The design was a self-controlled prospective study. Clouclip, with the vibration alert disabled, was first applied to measure baseline near-work behaviors in the first week.
Purpose: To compare light intensity and near-visual tasks objectively between rural and urban children.
Methods: Clouclip, a wearable device, was applied to assess metrics of these two factors in 78 fifth-grade students from an urban and from a rural school.
Results: The light intensity experienced by urban students was found significantly lower both in the school period (614.
