SUNY Study Ties Low-Light Close Focus to Myopia Progression

Researchers propose that reduced retinal illumination from pupil constriction during close work offers a single explanation for varied risks and treatments.

Overview

  • The hypothesis, published February 17 in Cell Reports by Maharjan et al. at SUNY College of Optometry, centers on how indoor near work in dim light limits retinal illumination.
  • Experiments show negative lenses and sustained accommodation constrict the pupil and reduce retinal light, with stronger effects at shorter distances and in myopic eyes.
  • The framework suggests myopia control is more likely when eyes receive safe bright light with limited accommodative constriction through multifocal or contrast-reduction lenses, atropine drops, or outdoor distance viewing.
  • The authors predict any control approach will falter if prolonged near focus continues indoors under low light, regardless of other measures.
  • The study presents a testable mechanism but does not change clinical guidance yet, and further validation and clinical trials are needed.
