Comparing Preschool-Aged Refractive Measurements and Amblyopia Risks Using the 2WIN-S Portable Refractor with Vision Screening by Cycloplegic Refraction in Bangkok

Stopped: Because the research team plans to change the protocol, we do not plan to conduct cycloplegic refraction, which requires dilation. Instead, we will use only 2-WINS for eye and vision screening. Additionally, we will change the study site
