TheraSpecs® Therapeutic Glasses for Blue Light

Learn about the wide range of therapeutic lens options that TheraSpecs offers to protect you from harmful blue light, whether you have light sensitivity, issues with sleep or vision, or simply need something to wear while looking at your screen.

TheraSpecs® offers a wide range of therapeutic glasses designed to reduce aggravating blue light. We have lens options that are designed to give you more protection against blue light from screens, LEDs and fluorescents, provide better relief for photophobia and light-sensitive conditions, and even can help improve your sleep. When compared with typical blue light glasses that only focus on a narrow spectrum of blue wavelengths, TheraSpecs eliminate more across a wider spectrum, including the wavelengths that are most likely to trigger migraine, post-concussion syndrome and other issues caused by light.

 What Our Customers Are Saying

Hanna wearing FL-Pro TheraSpecs for blue light

"I was previously wearing [other] blue blockers for my photophobia. I have found the TheraSpecs better for stopping or minimizing the photophobia, and my eyes have also been less dry. I've hardly needed to use eye drops, whereas before I was using them almost daily."
-Hanna, Australia, wearing FL-Pro (extra) lenses

Sean wearing FL-Pro Winslow TheraSpecs blue light glasses

"If I were to compare these TheraSpecs glasses to other blue light glasses, I would say it helped about 25-30% better, which is a game changer for me because I stare at a computer all day. And my eyes just honestly feel smooth."
-Sean P., Canada, wearing FL-Pro (extra) lenses

Aimee wearing Audrey FL-Pro TheraSpecs blue light filtering glasses

"After comparing various blue light-blocking glasses and other FL-41 lenses I decided to try TheraSpecs and I’m so glad I did! They have provided tremendous relief and allow me to function without the fear and dread of recurrent symptoms."
-Aimee, Texas, wearing FL-Pro (extra) lenses

Blue Light Affects Our Health In Different Ways
TheraSpecs Target the Right Wavelengths Based On Your Needs

Blue light is everywhere, but it is not just one wavelength of light that has a singular impact on our eyes and brains. It is an entire spectrum (400-500nm), with differing effects depending on the specific range and concentration of wavelengths and the person exposed to them.

For example, blue light near 480nm is the most likely to trigger photophobia and light-sensitive conditions like migraine, brain injuries, and vestibular disorders.1 Even a few seconds or minutes of exposure to these harmful wavelengths can bring on symptoms of headache, vertigo, aura, light sensitivity, and much more.

And we cannot escape this type of blue light: fluorescent lights, LEDs, computer and device screens, and sunlight. Plus, people with photophobia are extra sensitive to invisible flickering of fluorescent lighting and some LEDs, and this flickering is more prominent in the blue spectrum.2

Other points along the blue light spectrum also have harmful effects. Screen use can subject us to blue light in the 440-470nm range, which can lead to eye strain, fatigue, and blue light-induced headaches, even for a person without light sensitivity. It may also lead to a decline in general eye health too.3 Even our sleep can be disrupted by blue light, particularly when exposed in the hours before you go to bed.4

As a result of all of these issues related to blue light, TheraSpecs offers several lenses designed to address each of these unique challenges:

TheraSpecs Flex is the ideal option for mild light sensitivity and/or relief from screen-induced discomfort. Its barely-there tint provides relief in a subtle lens and blocks significantly more blue light compared to other glasses marketed for screen use.

TheraSpecs FL-Pro™ maximizes the filtering power of FL-41 to remove the most harmful wavelengths of blue light near 480nm and protect you against computer and device screens, fluorescent lighting, LEDs and other artificial sources.
Shop FL-Pro Lenses ➜

TheraSpecs FL-Blend™ also uses FL-41 and balances the filtering of triggering blue light with a less noticeable tint to provide meaningful relief for symptoms brought on by artificial sources.
Shop FL-Blend Lenses ➜

Both FL-Pro and FL-Blend are best for people with stronger light sensitivity. They also help further protect against fluorescent lights and LEDs by cutting down on the negative impact of invisible flicker.5

TheraSpecs Sleep lens blocks 100% of blue light in order to activate melatonin production and aid in a smoother transition to sleep. Wear them for 2-3 hours before your bedtime to maximize their sleep-enhancing benefits.

TheraSpecs Contrast HEV™ filters the high-energy visible blue light that our eyes don’t focus well, helping to bring greater clarity and contrast to your vision. It also removes much of the light that may negatively harm your long-term eye health.
