How do FL-Blend TheraSpecs work?

FL-Blend™ combines the right amount of critical protection against artificial light sources like fluorescents and digital screens with more natural color perception. A subtle take on the FL-41 lens tint, it targets harsh light between 480-520nm with a softer plum tint to ensure all-day comfort. If you are wanting a truer color experience from your eyewear, we recommend adding FL-Blend to your light management toolkit as it may help you live better with migraine, light sensitivity, brain injury symptoms, or other issues aggravated by light.
