Indoor Light and Close-Range Viewing May Drive the Global Myopia Rise
TL;DR Summary
A SUNY College of Optometry study with 34 participants suggests indoor lighting and sustained near-work can alter how the eye accommodates, converges, and constricts pupils in myopes, with contrast more influential than brightness in driving inward eye movements. This may weaken a retinal pathway and create a feedback loop that worsens myopia, offering a new hypothesis for the global rise (projected ~40% of youth affected by 2050). The study is small and not longitudinal, so outdoor vs indoor effects remain unproven and more research is needed.
