Yes, our FL-Pro lenses use the FL-41 tint, which filters the most harmful wavelengths of light between 480-520nm. These are the wavelengths most responsible for aggravating sensitivity to light.

With its precision filtering of 480-520nm, FL-Pro may also help people live better with migraine, as part of a light management plan.

Yes, our FL-Pro lenses filter blue light, and most strongly between 480-520nm, which is the part of the spectrum most associated with light sensitivity. Unlike typical blue light glasses with clear or nearly-clear lenses, which focus only on the part of the blue spectrum near UV light, FL-Pro filters a broader spectrum with a focus on those critical wavelengths.

Like all TheraSpecs lenses, FL-Pro also blocks 100% UV light and includes an anti-reflective coating.

FL-Pro is best suited for people with moderate to severe sensitivity to light, especially in environments with artificial lighting like fluorescent lights, LEDs, and device screens. They can be worn throughout the day in these settings.

FL-Pro lenses can also be worn outside, but they are designed primarily for artificial light rather than bright sunlight. For stronger protection in direct sun, a darker lens like FL-Sun may be a better fit.

Yes, FL-Pro is available in multiple tint strengths. The right option depends on your level of light sensitivity and how much filtering you need. Higher strengths provide more filtering for stronger or more frequent sensitivity. Here are the different strengths of FL-Pro:

FL-Pro (Standard)

FL-Pro (Extra)

FL-Pro (Max)

FL-Pro is part of our FL-41 lens family. These lenses use the same core tint but vary in strength and intended use. We also offer other lens options that target different parts of the light spectrum, so here’s how FL-Pro compares to all of our lenses:

No, FL-Pro TheraSpecs (all strengths) are too dark to use while driving at night. Instead, consider our Flex or Contrast HEV lens options.

Yes, you can get FL-Pro lenses with your prescription, or with reader correction (note: WearOver styles are non-prescription only.). 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.

You have 60 days for returns or exchanges of all non-custom TheraSpecs, so you can make sure FL-Pro is the best option for your needs. If you are wanting prescription or reader TheraSpecs, we suggest starting with one of our fully refundable fitover styles.
