5 Key Takeaways

• 1

  Francine Behar-Cohen said changes in light spectrum, intensity, and timing may contribute to rising myopia prevalence.

• 2

  Artificial lighting differs from daylight in its spectrum and can extend light exposure beyond natural daylight hours.

• 3

  Experimental studies suggest that wavelength, contrast, and temporal frequency can influence light’s effects on ocular growth.

• 4

  Observational and interventional studies associate increased outdoor exposure with reduced myopia onset in children.

• 5

  Behar-Cohen recommended at least 11 hours outdoors weekly, more natural light indoors, and limiting screen exposure before bedtime.
