Balances protection against screens and other artificial light with a less noticeable color

FL-Blend™ is a more subtle take on the FL-41 lens tint, balancing the removal of harmful light with a less noticeable lens color. This plum-colored lens also targets the harmful wavelengths that trigger or worsen migraine, concussion, and other light-sensitive conditions, keeping you protected against artificial sources like fluorescents and digital device screens.
