HELPS ME GET THROUGH
"I’ve been suffering from an eye condition for almost 7 years now called floaters...The only thing that really helps get me through and ignore the floaters is these nifty lil glasses from TheraSpecs. The relief the tinted outdoor lenses bring me compared to any other pair I’ve tried is incomparable. Not to mention they are pretty damn cool looking."

Not All Light is Created Equal
Light sensitivity and other symptoms are more likely to be triggered by a specific range of wavelengths in the blue-green spectrum (480-520nm).1 These wavelengths are almost inescapable in our daily lives, from the screens we stare at to the bright, artificial light of the stores we visit.
If you’re somebody who gets migraine attacks, headaches, or other symptoms due to light, you should have access to the right tools to help you manage this disruptive lighting.
TheraSpecs FL-41 Protection and Light Management
The TheraSpecs FL-41 tint is more than just a lens color. It is designed to target specific wavelengths between 480-520nm and filter more of this problematic light when compared with typical blue light glasses.2 As a result, TheraSpecs FL-41 lenses are frequently recommended by medical professionals for their headache, migraine, and post-concussion patients, among others, as part of a comprehensive light management plan.
TheraSpecs offers four FL-41 lens options, as well as several lens strengths, to meet your needs, each of which are precisely tinted and verified to filter these disruptive wavelengths.
TheraSpecs FL-Pro™ maximizes the filtering power of FL-41 to remove the harsh wavelengths of light at 480-520nm, present in computer and device screens, fluorescent lighting, LEDs and other artificial sources. Shop FL-Pro Lenses ➜
TheraSpecs FL-Blend™ also uses FL-41 and balances filtering of the critical wavelengths between 480-520nm with more natural color perception to provide protection from artificial light. Shop FL-Blend Lenses ➜
TheraSpecs Flex is the lightest FL-41 lens we offer and is designed for people who need to help take the edge off of their screen or artificial light and/or for those who need protection while driving at night. Shop Flex Lenses ➜
TheraSpecs FL-Sun™ embraces the benefits of FL-41 by applying the tint to dark, polarized lenses that block more than 93% of the most uncomfortable wavelengths of light. They tame bright sunlight and harsh glare, making them the best sunglasses you’ll own. Shop FL-Sun Lenses ➜
TheraSpecs are also available with frames that are designed to cover a wide range of needs and lighting situations. Many styles effectively block light from above and the sides, and all TheraSpecs are as lightweight as possible and add flexibility to minimize pressure on already-sensitive heads.
