GoKawiilUGA Study Finds Blue Light Reduces Eye's Ability to Resolve Fine Detail
A University of Georgia study tested 60 young adults on their ability to distinguish two close points of light under different colors, finding that blue light caused the greatest scattering and optical aberration in the eye, requiring points to be farther apart to be seen as separate. Green, yellow, red, and broadband light produced comparatively less scatter. The researchers also found iris pigmentation affected results, with lighter-colored eyes showing different sensitivity.
