Epilepsy Filters


Like concussions, traumatic brain injuries (TBIs) can actually cause epilepsy. Considering TBIs have a significant impact on vision, it's not surprising that some types of epileptic seizures can be triggered by what we see; more precisely, the type of vision-based stimuli we take in.

Our epilepsy glasses, with a Z Blue functional filter, may provide significant relief and even help prevent seizures from happening; especially for those suffering from photosensitive epilepsy. These specially tinted lenses block out much of the offending light-based stimuli and prevents it from triggering a seizure. The tint most effective for epilepsy is Z Blue (equivalent to z1 blue or noir 26).
