Learn about the wide range of lens options that TheraSpecs offers to protect you from unwanted blue light, whether you simply need something to wear while looking at your screen or want advanced defense for more intense light sources.
TheraSpecs® offers a wide range of light-filtering glasses designed to reduce harsh blue light. We have lens options that are designed to give you protection against blue light from screens, LEDs and fluorescents; as part of an overall light management plan, TheraSpecs may also help if you are living with photophobia or a light-sensitive condition, and may help improve your sleep if that is a concern. When compared with typical clear- or nearly-clear blue light glasses that only focus on a narrow spectrum of blue wavelengths, TheraSpecs filter more across a wider spectrum, so you can stay protected from light wherever you go.1
TheraSpecs customers say that our glasses outperform the competition. For example, they rated TheraSpecs FL-Pro glasses as 3X more likely to improve symptoms like headaches and photophobia when compared with other blue-light filter eyewear they tried, according to our survey.2
In addition, TheraSpecs customers have shared that they purchased our glasses for issues like:†
★★★★★
BETTER FOR PHOTOPHOBIA
"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
★★★★★
A GAME CHANGER
"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
★★★★★
TREMENDOUS RELIEF
"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 May Affect You Health In Different Ways
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.3 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.4
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.5 Even our sleep can be disrupted by blue light, particularly when exposed in the hours before you go to bed.6
All of this makes managing blue light exposure a necessary activity for so many people.
TheraSpecs for Blue Light Management
TheraSpecs offers several lenses designed to address each of these unique situations where blue light may be problematic:
TheraSpecs Flex is our recommended option for the light management toolkits of people living with mild light sensitivity and/or screen-induced discomfort. Its barely-there tint provides protection in a subtle lens and blocks significantly more blue light compared to other clear- or nearly-clear glasses marketed for screen use. Shop Flex Lenses ➜
TheraSpecs FL-Pro™ maximizes the filtering power of FL-41 to filter the problematic 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 unwanted blue light with a less noticeable tint to provide good protection against artificial sources. Shop FL-Blend Lenses ➜
As part of a general light management strategy, we recommend both FL-Pro and FL-Blend for people living with stronger light sensitivity. They also help further protect against fluorescent lights and LEDs by cutting down on the wavelengths where these sources emit an invisible flicker.7
TheraSpecs Sleep lens blocks 100% of blue light, which may affect sleep patterns and melatonin production. Wear them for 2-3 hours before your bedtime to maximize your protection in the evening. Shop Sleep Lenses ➜
TheraSpecs Contrast HEV™ filters the high-energy visible blue light that our eyes don’t focus well. As a result, this lens may provide improved visual contrast and sharpness for a wide range of situations. Shop Contrast HEV Lenses ➜
TheraSpecs Lenses:
Filter specific wavelengths of blue light for different needs and lighting situations
Protect against fluorescent, LED, and other artificial lighting
Are great for numerous activities like gaming, shopping, watching TV, using the computer, and more
Cut out more blue light when compared with typical clear- or nearly-clear blue light glasses1
