Scientists are uncovering a surprising link between indoor LED lighting and the global surge in nearsightedness—blame the missing indigo light. In a breakthrough study using tree shrews (whose eyes mirror ours), exposure to indigo prevented nearsightedness entirely. Since natural sunlight contains this vital wavelength, artificial lights lacking it may be disrupting eye development, causing eyeballs to elongate and blur distance vision. Researchers now plan to test indigo-enriched lighting in daycares to see if it can curb myopia rates in kids—potentially offering a simple, preventative fix…
