Wavelengths from 480–570 nm also produce secondary circadian effects, with human sensitivity gradually decreasing as wavelength increases. A subset of people with photophobia experience discomfort specifically to the 480–520 nm band — FL41 lenses are formulated for this group.\u003c\/strong\u003e\u003c\/p\u003e \n\u003cp\u003e\u003cstrong\u003eNo single lens performs optimally for both day and night.\u003c\/strong\u003e\u003c\/p\u003e \n\u003cp\u003e\u003cstrong\u003eOur daytime clip-ons (FL41B \/ clear) filter excess harsh glare and unwanted screen blue light, while preserving the beneficial circadian signals your body needs.
