The Claim
Children carrying the PDE10A rs12206610 CT genotype who engage in more than five hours per day of near-work activities have a 4.29-fold increased risk of developing incident myopia compared to children without this genotype and with lower near-work exposure.
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 spend more than five hours daily on close-up tasks like reading or screen use are 4.29 times more likely to develop nearsightedness than children without this variant and with less close-up work.

Children carrying the PDE10A rs12206610 CT genotype who engaged in more than five hours per day of near-work activities had a 4.29-fold increased risk of incident myopia compared to those without this genotype and lower near-work exposure, indicating a gene-environment interaction in myopia development.
A specific gene version changes how retinal cells manage a chemical signal that controls eye growth. When the eyes are focused on close objects for long periods, this altered signal causes the eyeball to stretch too long, leading to blurry distance vision.
What the research says
1 studyKids with a certain gene version who spent more than 5 hours a day reading or doing close-up work were over four times more likely to become nearsighted than kids without that gene or with less close-up work.
