• The nearsightedness explosion may be fueled by dim indoor light, not just screens Nearsightedness has surged to near-epidemic levels, and new research suggests screens may not be the whole story. • For years, the sharp rise in myopia – or nearsightedness – has largely been blamed on growing screen use, particularly among children and young adults. • However, new research from scientists at the SUNY College of Optometry suggests the explanation may be more nuanced. • A study scheduled for publication inCell Reportsproposes that myopia may be influenced less by screens themselves and more by a common indoor behavior: extended close-up focusing in dim lighting, which reduces the amount of light reaching the retina. • “Myopia has reached near-epidemic levels worldwide, yet we still don’t fully understand why,” said Jose-Manuel Alonso, MD, PhD, SUNY Distinguished Professor and senior author of the study. • “Our findings suggest that a common underlying factor may be how much light reaches the retina during sustained near work – particularly indoors.” Myopia Rates Are Climbing Worldwide Myopia (nearsightedness) causes distant objects to appear blurry and has become increasingly common around the globe.

- Summary
A new study from SUNY College of Optometry suggests that the global surge in myopia may be driven more by indoor lighting conditions than by screen use alone. Researchers propose that prolonged close‑up focus in dim environments causes pupils to constrict, reducing retinal illumination and potentially triggering eye growth changes that lead to nearsightedness. The hypothesis links various myopia‑control methods-atropine drops, multifocal lenses, and outdoor time-through a shared mechanism involving retinal light exposure. If confirmed, the findings could shift public health strategies toward improving indoor lighting to curb the rising myopia epidemic.
