TheraSpecs® Glasses for Photosensitive Epilepsy and Seizures

TheraSpecs lenses provide protection and relief from strobing and flashing lights as well as static patterns that can trigger seizures for people with photosensitive epilepsy

For people with photosensitive epilepsy or other seizure disorders, lights that are bright or lighting that flickers, flashes, or strobes can be particularly triggering for seizures. Even static, repeating patterns can overwhelm a photosensitive brain. This can prevent people from taking pleasure in everyday things like going to movies or concerts and enjoying sunlight flickering through trees. By protecting the part of the brain that responds to these visual stimuli, TheraSpecs® can reduce or eliminate symptoms triggered by this light.

What customers are saying

Kristine wearing FL-Pro glasses for photosensitivity

"I have epilepsy and severe migraines. I get dizzy a lot in fluorescent lighting in stores. So I gave [TheraSpecs] a try. Today I worked all day in fluorescent lighting and my head was feeling the best ever after a long of work."
-Kristine, wearing FL-Pro (extra) lenses

Charity's son wearing FL-Pro Wrap TheraSpecs for seizures

"My son (who has epilepsy) was able to return to school after getting a pair of prescription TheraSpecs! He was taking online schooling at home due to the flourescent lights in the school triggering his focal seizures, which in turn were happening so frequently that they were triggering his grand-mal seizures. He's been back in school for 4 weeks now sporting his new TheraSpecs and doing great."
-Charity, Michigan, wearing FL-Pro (extra) lenses

Cassidy wearing FL-Pro TheraSpecs photosensitive epilepsy glasses

"I ordered them because I have epilepsy and that is mainly why I am light sensitive. Before TheraSpecs I couldn’t go to concerts, school dances when I was in high school or even drive all the time. Now I can look at lights again without getting headaches or worrying about seizures, and best of all I am gaining my independence back!"
-Cassidy, Illinois, wearing FL-Pro (extra) lenses

TheraSpecs Can Reduce Seizures, Photosensitivity

Photosensitive epilepsy is a condition whereby light or other visual stimuli can lead to the onset of seizures, and it affects hundreds of thousands of people. In particular, flashing or strobing lights are a major threat for triggering seizures, along with bright lights, striped patterns, and other sources. Here are just some of the aggravating light sources that comes with photosensitivity and seizures:

  • Flicker on TV screens or computer monitors
  • High contrast lighting (such as viewing a bright screen in a near-dark room)
  • Malfunctioning light sources, such as fluorescents, that flicker or flash
  • Movies or video games that contain rapid flashes or alternating patterns
  • Strobe lights, such as those at a concert or athletic game
  • Sunlight flickering through trees, glimmering on water, or streaming through the slats of window blinds
  • Emergency lights on vehicles or visual fire alarms

The brain reacts similarly to striped or repeating patterns, which can also lead to symptoms. These patterns increase the intensity of a brain wave called gamma oscillations.1 Even static images with these patterns can trigger seizures in as many of 30% of people with photosensitive epilepsy, according to research.2

In addition, certain wavelengths of light have been shown to more negatively affect a photosensitive brain, and this light comes at us from all directions—our screens, fluorescent lighting, LEDs, and sunlight.3

By calming the brain’s response to these visual triggers, research shows that TheraSpecs can provide relief.

TheraSpecs Z-Blue™ (max strength) is crafted to provide optimal protection against uncomfortable lighting and triggering patterns. Studies show Z-Blue max strength can protect people with photosensitive epilepsy and reduce seizures.4,5

TheraSpecs FL-Pro™ can also provide protection against photosensitive triggers. Customers have been using FL-Pro in extra strength since 2012 to manage seizures brought on by flashing lights, as well as reduce migraines, headaches, photophobia, and other symptoms due to light.6,7

TheraSpecs FL-Sun™ can be worn outside to help manage sunlight flicker through trees to provide relief. (Z-Blue max can also be worn outdoors—FL Sun is an option if you’re looking for a darker, polarized lens.)

Extra discounts are also available when you buy more than one pair. Plus, multiple frame options available and the choice to send in your own frame, you can also make sure to find migraine and headache relief that fits your style.

Research shows that TheraSpecs:

  • Lessen seizures from flashing and/or bright lights
  • Reduce the negative effects of fluorescent lighting, screens, and other sources
  • Block the harmful light associated with migraine attacks, headaches and photophobia
