Do TheraSpecs use FL-41?

Our FL-Pro™, FL-Blend™, Flex™, and FL-Sun™ lenses use the FL-41 tint to target uncomfortable wavelengths, giving you the protection you deserve. If you’re not familiar with the power of FL-41, these lenses are designed to reduce the irritating light between 480-520nm. As part of a light management plan, filtering these wavelengths may help people living with migraines, headaches, photophobia, post-concussion symptoms, and other light-sensitive disorders.

FL-Pro offers the strongest protection against artificial light sources like screens and fluorescents. If you are looking for a softer tint that still delivers solid defense against these sources, you might try FL-Blend.

Flex is the lightest version of FL-41 we offer; it is even light enough to be worn while driving at night, if headlights and other bright light on the road is irritating.

FL-Sun features dark, polarized FL-41 lenses to give you more protection when outdoors than normal sunglasses.
