The Claim
Children carrying the PDE10A rs12206610 CT genotype who used electronic devices for more than one hour per day had a 3.43-fold increased risk of incident myopia compared to non-carriers with less than one hour of daily electronic device use.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Children with a specific genetic variant who use electronic devices more than one hour per day have a 3.43 times higher rate of developing myopia than children without this variant who use devices less than one hour per day.
See the scientific wording
Children carrying the PDE10A rs12206610 CT genotype who used electronic devices for more than one hour per day had a 3.43-fold increased risk of incident myopia compared to non-carriers with less device use, suggesting a specific interaction between this genetic variant and electronic screen exposure in myopia development.
Children with this gene variant have a stronger drop in dopamine in the retina when they stare at close screens for long periods. This drop tells the eye to keep growing longer, which makes distant objects appear blurry.
What the research says
1 studyKids with a certain gene version who used screens more than an hour a day were over three times more likely to become nearsighted than kids without that gene version and less screen time — and the study found this exact link.
