The nearsightedness explosion may be fueled by dim indoor light, not just screens

Myopia is skyrocketing around the world, often blamed on endless screen time — but new research suggests the real culprit may be something more subtle. Scientists at SUNY College of Optometry propose that it’s not just devices, but the combination of prolonged close-up focus and dim indoor lighting that may quietly strain the eyes. When we concentrate on nearby objects in low light, our pupils constrict in a way that may reduce how much light reaches the retina, potentially triggering changes that lead to nearsightedness.
