Episode notes
Myopia Is Becoming A Global Trend
- Myopia prevalence is rising globally and may affect almost 60% of people by 2050.
- Researchers link the rise to lifestyle changes like less outdoor time and more close-up viewing.
Genes Plus Modern Life Increase Risk
- Myopia is partly genetic: two myopic parents multiply a child's risk by six.
- Modern environments amplify risk through more screen use and less daylight exposure.
Daylight Slows Eye Elongation
- Eyes elongate when focusing on nearby objects, shifting focus in front of the retina.
- Daylight triggers dopamine that slows eye elongation and reduces myopia progression.
