Frequently Asked Questions about FL-Blend
Does FL-Blend use FL-41?
Yes, our FL-Blend lenses use the FL-41 tint, which filters the most harmful of wavelengths of between 480-520nm, which are most responsible for aggravating light sensitivity. FL-Blend trades some protection for more natural color perception.
Does FL-Blend filter blue light?
Yes, our FL-Blend lenses filter light 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-Blend also blocks 100% UV light and features an anti-glare coating to further enhance your comfort.
How does FL-Blend differ from FL-Pro?
FL-Blend targets the same wavelengths as FL-Pro with a subtler, plum-colored lens. As a result, there is less of a noticeable color change while wearing FL-Blend. If you want the strongest defense against artificial light and/or experience more severe light sensitivity, we recommend trying FL-Pro first.
In addition, FL-Blend is available in two lens strengths, whereas FL-Pro offers three strengths, all of which can help meet your specific needs.
Is FL-Blend right for me?
We recommend FL-Blend if you experience mild or moderate light sensitivity and/or if you want a more subtle lens option to fight against artificial light, such as computer and device screens, fluorescent lights, and LEDs. With its advanced filtering properties, FL-Blend can also help people to live well with migraine, as part of a light management plan.
If you're still not sure, you can answer a few questions and get instant recommendations from our lens assistant.
Can I get FL-Blend TheraSpecs in my prescription or as readers?
Absolutely! You can get FL-Blend lenses with your prescription, or with reader correction. Simply tap/click on your preferred frame style above, choose either "Prescription" or "Reading Glasses" under Lens Correction, and complete the rest of the options before adding to your cart.
What if FL-Blend does not work for me?

Enjoy balanced protection and see the world more naturally
FL-Blend™ combines the right amount of critical protection against artificial light sources like fluorescents and digital screens with more natural color perception. A subtle take on the FL-41 lens tint, it targets harsh light between 480-520nm with a softer plum tint to ensure all-day comfort. If you are wanting a truer color experience from your eyewear while still helping to manage your light sensitivity, we recommend FL-Blend for a balanced solution.
FL-Blend reduces exposure to problematic light, which may help people to live well with migraine as part of an overall light management plan.
