- Why 480–520nm Light Irritates Eyes Human eyes have rods (night vision) and cones (color & detail).In early 2000s, scientists found ipRGCs, a third light-sensing cell. It carries melanopsin, highly sensitiveto 480–520nm cyan-green light. Too much light in this band triggers glare and eye discomfort from LEDs,fluorescent lights and sunlight. 2. Where FL41 Comes From FL41 stands for Fluorescent Light Formula 41, created in late 1980s by Professor Arnold Wilkins in Birmingham,UK. Old office fluorescent lights flicker invisibly with strong 480–520nm spectrum, causing eye strain forworkers. After many trials, his 41st rose-tint lens formula perfectly filters harsh fluorescent light, named FL-41. 3. How FL41 Lenses WorkOriginally made for office eye fatigue relief.FL41 rose lenses block irritating 480–520nm cyan-green light and cut glare from screens, lamps and sun.Different from dark sunglasses, it stays transparent indoors without dim vision, also softens harsh outdoorlight for office, study and daily outdoor use. please check the size before your order. this is very important.
