Europe Observational Epidemiology Study Students Elementary (K-5) Middle/Jr High (6-8) Lighting Vision Ireland Ocular biometry Refractive error School children Time spent outdoors This study measured ocular biometry and refraction in Irish children aged 6–7 and 12–13, finding more daylight exposure in summer was linked to less axial elongation; suggests increasing outdoor time may help limit myopia progression.
