Notes: Abstract The aim of our work was to test a particular type of lens for photosensitivity control in photosensitive epileptic patients. Previous papers considered color and shade of dark to test lens efficacy. We added a new variable, namely lens material, to these well-known variables. We performed electroencephalography (EEG) and simultaneous video recordings in 83 epileptic patients to evaluate the effectiveness of these experimental blue lenses on photoparoxysmal response (PPR). In addition, we compared the lenses with four other types of commercially available lenses. We found that the experimental lens type was very effective for photosensitivity inhibition in epileptic subjects. Indeed, PPR disappeared in 64 of 83 patients (77%) and diminished in 16 (19%). All the other commercial lenses were less effective. We think that this particular lens type could be useful in managing photosensitive epileptic patients.
