A missing color in indoor light may help prevent myopia
Researchers have discovered that exposure to indigo light, a wavelength found in natural sunlight but missing from standard LEDs, may prevent myopia in tree shrews. This finding suggests a potential non-invasive method to combat the rising global prevalence of nearsightedness in children.
Why it matters
With nearly 50% of the global population projected to be nearsighted by 2050, this discovery could lead to new indoor lighting standards that protect long-term eye health.
Children who spend more time indoors looking at screens and less time outside are more likely to develop myopia, also known as nearsightedness. The problem is growing rapidly worldwide, with some experts estimating that nearly 5 billion people (or 50% of the world population) could be nearsighted by 2050.
