TheraSpecs® Sunglasses for Sunlight Sensitivity

TheraSpecs sunglasses provide the ultimate protection for anyone who finds sunlight bothersome, including people with migraine, headache, post-concussion syndrome, photophobia, and other symptoms triggered or worsened by sunlight

By targeting the wavelengths of light that the brain perceives as brightest, TheraSpecs® FL-Sun™ sunglasses provide a superior lens for anyone who finds sunlight uncomfortable. These are the same wavelengths of light that research shows cause the most pain and other symptoms for people who have migraine, brain injuries, and other light-sensitive conditions. Our FL-41 sunglasses relieve painful light sensitivity and photophobia, reduce migraine attacks, and protect from harsh sunlight. Their dark, polarized lenses reduce glare and they block 100% of UVA and UVB light.

Not All Sunglasses Deliver the Same Protection

The best sunglasses are more than just dark lenses. By adding FL-41 to a dark lens, TheraSpecs FL-Sun™ block light at the specific wavelengths that research shows cause the most problems for people who are sensitive to sunlight. Sunlight is exceptionally high in these wavelengths—it can emit 250 times of these wavelengths as artificial light—which can make it too bright even for people who don’t have a health condition.1

TheraSpecs FL-Sun lenses perform better than prominent eyewear brands at the most critical wavelengths (including protection from outdoor blue light). Even other FL-41 products do not match the properties of TheraSpecs sunglasses, making TheraSpecs the best sunglasses for outdoor sensitivity. That extra protection can make all the difference when you are sensitive to light and/or have a condition like migraine or post-concussion syndrome.

TheraSpecs sunglasses also feature polarized lenses and 100% UVA/UVB blocking. Polarization helps eliminate reflective glare and increases the darkness of the lenses, while maximum UVA/UVB protection cuts down on non-visible ultraviolet light that can harm our eyes.

All these factors combine to bring enhanced comfort when you’re outdoors.

TheraSpecs FL-Sun comes standard with Dark+ strength. And if those aren’t dark enough, we also make TheraSpecs FL-Sun UltraDark+ as a specialty lens to block even more harsh sunlight. They are so dark that they are not suitable for driving, but are excellent for other outdoor activities.

Research shows that TheraSpecs sunglasses:

  • Block harsh sunlight and more than 92% of symptom-triggering wavelengths
  • Relieve painful light sensitivity and photophobia
  • Reduce migraines and headaches by up to 74 percent
  • Minimize glare with polarized lenses
  • Block 100% of UVA/UVB light
