Yes, our FL-Pro lenses filter most strongly between 480-520nm, which is in the blue-green spectrum. They also remove more wavelengths across a wide spectrum of blue light than typical clear- or nearly-clear blue light glasses.

Like all TheraSpecs lenses, FL-Pro also blocks 100% UV light and features an anti-glare coating to further enhance your comfort.

We recommend FL-Pro TheraSpecs if you experience moderate or severe light sensitivity and/or if you want the strongest protection against artificial light, such as computer and device screens, fluorescent lights, and LEDs. With its advanced filtering properties, FL-Pro TheraSpecs can also help people to live well with migraine, as part of a light management plan.
