The Claim
In adolescents aged 8–16, longer durations of near work are associated with more severe myopia as measured by spherical equivalent refraction.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adolescents aged 8–16 who spend more time doing close-up tasks like reading or screen use have greater degrees of nearsightedness, measured by standard eye exams.
See the scientific wording
In adolescents aged 8–16, longer durations of near work were associated with more severe myopia, as measured by spherical equivalent refraction, suggesting a potential link between prolonged close-up tasks and myopia progression.
When the eyes focus on close objects for long periods, the lens thickens and the eyes turn inward more than needed. This mismatch sends a signal to the back of the eye to grow longer, which causes light to focus in front of the retina instead of on it, making distant objects appear blurry.
What the research says
1 studyStudy: Multi-Interactive-Modality Based Modeling for Myopia Pro-Gression of Adolescent Student
Kids who read or use screens for long hours, hold things too close, or work in dim light tend to have worse eyesight, according to this study. It doesn’t say screens cause bad eyesight, but it shows they’re linked.
