From article.
I found a study which shows that Carl Zeiss brand z1 blue lenses are highly effective in treating photosensitive epilepsy. The study is at: http://www.blackwell-synergy.com/doi/full/10.1111/j.1528-1167.2006.00463.x?prevSearch=allfield%3A%28z1%29.
These lenses are available in Europe, but I haven't been able to find them in the US or on the internet. I emailed Zeiss customer service about this, but I got no response. Does anyone know where I can find these lenses. I suffer from photosensitivity (as well as temporal lobe epilepsy). I use polarized glasses, and these help some, but I'd really love to try these lenses.
Seizure. 1999 Dec;8(8):444-9. Treatment of photosensitive epilepsy using coloured glasses. Wilkins AJ1, Baker A, Amin D, Smith S, Bradford J, Zaiwalla Z, Besag FM, Binnie CD, Fish D. Author information Abstract
A recently introduced optometric technique, colorimetry, enables the perceptual effects of ophthalmic tints to be evaluated subjectively, optimized, and then prescribed in tinted spectacles. The new technique is beneficial in reducing visual stress in patients with dyslexia and migraine. We describe an open trial designed to ascertain: (1) whether the colorimetry assessment, as it is now given, is safe for the investigation of photosensitive patients in optometry clinics where colorimetry equipment is most readily available, but where EEG control is not practical; (2) what proportion of patients with photosensitive epilepsy is likely to benefit to the extent already described in individual cases; (3) whether a tint selected by colorimetry could be shown to reduce the incidence of paroxysmal epileptiform EEG activity in response to flicker and patterns, thereby validating the subjective methods and corroborating the reported seizure reduction. Twenty-four females and nine males (aged 12-43 years) took part. All the patients had suffered visually-provoked seizures, had exhibited a photoparoxysmal response on at least one previous EEG recording, and had received a diagnosis of photosensitive epilepsy. Twenty-two were currently experiencing seizures. A further EEG was recorded in all except seven cases: a routine resting record, followed by hyperventilation. Colorimetry was performed after hyperventilation and before photic stimulation. Twenty-three (70%) reported beneficial effects during colorimetry and were prescribed glasses. There was a preponderance of lenses with a rose or purple colour, in contrast to patients with dyslexia.

Look at this funny advertisement on the Washington Post article about Hillary's collapse.
Certainly appears to be the same glasses.
