The Claim

Genetic variants involved in neuronal signaling and synaptic development, including GJD2, RBFOX1, KCNQ5, and LRRC4C, exhibit the strongest interaction with education in relation to myopia risk.

How it works
1 study reviewed
In plain English

Specific genetic variants related to nerve cell communication and brain development show the strongest link between years of education and the likelihood of developing myopia.

See the scientific wording

The interaction between education and myopia risk is strongest for genetic variants involved in neuronal signaling and synaptic development, including GJD2 (connexin-36), RBFOX1 (splicing regulator), KCNQ5 (potassium channel), and LRRC4C (netrin-G ligand), suggesting biological pathways linking visual environment exposure to eye growth regulation.

Why this might work

Spending more time in school reduces time outdoors and increases close-up visual tasks, which changes how light focuses on the retina. This altered visual input interacts with genetic variants that weaken communication between retinal nerve cells, disrupt the balance of electrical signals, and impair the development of visual pathways. These changes send incorrect signals to the back of the eye, causing the eyeball to grow too long, so light focuses in front of the retina instead of on it, leading to nearsightedness.

  1. Study: Education interacts with genetic variants near GJD2, RBFOX1, LAMA2, KCNQ5 and LRRC4C to confer susceptibility to myopia

    This study found that kids who spend more years in school are more likely to become nearsighted if they have certain genes that help nerve cells in the eye communicate and connect — meaning school might affect eye growth through these biological pathways.
