TheraSpecs® Glasses for Flashing Lights and Repeating Patterns
TheraSpecs lenses provide defense against the disruptive wavelengths emitted by flashing lights and repeating patterns.
Whether you’re exposed to the flashing of sunlight through trees, invisible flicker from screens, strobe lights, or even striped patterns, TheraSpecs® glasses can keep you protected in just about any lighting situation. As part of an overall light management program, our lenses may help defend you from the irritating part of flashing lights and repeating patterns—especially if you’re living with photosensitive seizures or other light-triggered symptoms from TBI, post concussion syndrome, epilepsy, or migraine.
Lens Options for Managing Flashing Lights and Repeating Patterns
Our customers have told us their lives have changed with the protection of our lenses. Repeatedly, they report they are able to better tolerate lighting environments that used to give them trouble. Here are a few of their wonderful stories:
What customers are saying
★★★★★
A RELAXING FEELING
"I wear TheraSpecs any time I’m on the computer, under artificial lights, anywhere lights are flashing, in traffic and in the outdoor sunlight. It’s like a relaxing feeling to go about my day. I didn’t realize pain and discomfort wasn’t normal in your eyes, in lighted situations!"
-Jen, Australia, wearing FL-Pro (extra) lenses
★★★★★
MY HEAD ISN'T HURTING
"I’ve mentioned before I have chronic migraines, so when I’m driving flashing lights tend to cause my head to hurt. Since wearing TheraSpecs (the sunglasses pictured above) my head isn’t hurting when I drive! Wahoo!"
-Christi, Virginia, wearing FL-Sun lenses
★★★★★
SEIZURE-FREE CONCERT
"I'm happy to announce that the TheraSpecs really helped me at the Queen concert!!! I didn't have a seizure at all. I did have to cover my face during the super strobing parts, but they really helped with the lights."
-Angela, wearing FL-Sun lenses

The Impact of Sensitivity to Flashing Lights and Repeating Patterns
Flashing lights are a well-known trigger for photosensitive epilepsy. 80% of people with migraine report sensitivity to flashing lights and research also shows that people who have had TBIs or have post-concussion syndrome are also sensitive to flashing lights.1 These lights include:
Computer, device, and TV screens
Movies or video games that contain rapid flashes or alternating patterns
Strobe lights
Sunlight flickering through trees, glimmering on water, or streaming through the slats of window blinds
Emergency lights on vehicles or visual fire alarms
Repeating patterns cause a similar reaction in the brain, which can also trigger symptoms. This is because these repetitive patterns increase the intensity of a certain type of brain wave, called gamma oscillations.2 Even people without epilepsy experience this type of neural activity, which can lead to feelings of discomfort or provoke symptoms associated with migraine or post-concussion syndrome. By calming the brain’s response to these patterns, research shows that TheraSpecs can provide relief.
Given the significant impact of these types of environments, many people remain invested in managing the problematic light that they encounter.
TheraSpecs for Light Management
Three lens options are available for managing flashing and strobing lights, disruptive patterns, and other challenging environmental:
TheraSpecs Z-Blue™ is designed to provide optimal protection against harsh and/or flashing lights and repeating patterns. As part of an comprehensive light management approach, we recommend Z-Blue lenses for people living with photosensitive epilepsy and seizures (particularly Z-Blue Max strength), as well as those with general hypersensitivity after a brain injury. Shop Z-Blue Lenses ➜
TheraSpecs FL-Pro™ may also provide protection against flashing lights or repeating patterns with its specialized FL-41 tint. Since 2012, our customers have told us they purchased these lenses to manage the problem wavelengths associated with conditions triggered by flashing lights, including migraine, TBI and post-concussion syndrome, and seizure disorders.4 Shop FL-Pro Lenses ➜
TheraSpecs FL-Sun™ embraces the benefits of FL-41 by applying the tint to dark, polarized lenses that filter more than 93% of problematic light.5 They may help manage sunlight flicker through trees to provide protection. Shop FL-Sun Lenses ➜
