FL-41 Glasses

Glasses with the FL-41 tint are great for photophobia associated with migraine and other light sensitive conditions. Research shows that FL-41 glasses relieve painful light sensitivity, reduce migraine attacks, and protect from fluorescent lighting by filtering the blue wavelengths of light that cause the most pain response. TheraSpecs block up to 25 times more of this harmful light than other blue light glasses.1 But not all FL-41 tinted glasses are equal. Unlike other FL-41 glasses, TheraSpecs lenses are measured to verify they are blocking the right amount of the most problematic wavelengths and their frames are designed to maximize relief.

Fl-41 Glasses by TheraSpecs

Designed for Maximum Relief

TheraSpecs are the only FL-41 glasses designed specifically for migraine sufferers and people who have light sensitivity. Many existing styles effectively block light from above and the sides, and all TheraSpecs are ultra-lightweight and flexible to minimize pressure on already-sensitive heads. The FL-41 tint cannot be added to existing lenses, but prescription TheraSpecs can be created with our precision tint. Custom frames—in any style you choose, including clip ons—can also be fitted with TheraSpecs lenses.

Research shows that TheraSpecs FL-41 lenses:

  • Relieve painful light sensitivity

  • Reduce migraines and headaches

  • Protect you from fluorescent lights
