Researchers at The University of Texas
Medical School at Houston discovered that coloured lenses
versus control lenses may actually rid migraine suffers of
their crippling pain. "These lenses provide fast relief, but
it doesn't work for everybody," says Dr. Thomas Prager,
clinical professor of ophthalmology at the University of
Texas Medical School.

The optometric correlates of migraine. The quality of the evidence to suggest a relationship between migraine headache and pupil anomalies, visual field defects and pattern glare is stronger. In particular the link between migraine headache and pattern glare is striking. The therapeutic use of precision-tinted spectacles to reduce pattern glare (visual stress) and to help some migraine sufferers is described.

Tinted spectacles and visually sensitive
migraine. The tints were supplied in random order, each for 6 weeks, separated by an interval of at least 2 weeks with no tints. Headache diaries showed that the frequency of headaches was marginally lower when the 'optimal' tint was worn, compared with the 'control'.

Optometric function in visually sensitive
migraine before and after treatment with tinted spectacles. The effects of precision tinted and control tinted lenses were investigated. The only variable to show a consistent and marked improvement with tinted lenses was pattern glare.

A preliminary study by D.W. Riley and A.
Wright (October 2000) comprised 30 people ranging in age
from 10 to 60+. The diagnosis of migraine was by doctor or
specialist for 21 of the subjects, with the remaining 9
being self-diagnosed. All the subjects had been assessed for
Irlen Syndrome and had been wearing Irlen Colored Filters
for 6 months to 5 years. For 83% of people in the study,
Irlen Filters reduced the frequency and severity of their
migraines.

Thirty-three patients with a history of
migraines associated with photophobia were given specially
made red-tinted contact lenses to insert during acute
attacks. Thirty-one patients experienced rapid pain relief,
of whom 26 had complete relief. For most patients,
improvement began within 5 minutes, and pain relief was
maximal within 90 minutes. In 5 cases, complete relief of
pain occurred within 10 seconds of inserting the lenses. The
contact lenses used were dark red and blocked 90% of
wavelengths of 600 nm or less, while admitting 90% of
wavelengths of 700 nm or more.

CASE STUDY: LH is a 40-year-old woman, who
has suffered with migraines at a frequency of two per month.
She is a patient at the National Hospital for Nervous
Diseases, a major London hospital. Currently, she has been
prescribed Imigran to control her symptoms. In September
1995, the hospital recommended that LH should obtain tinted
spectacles for additional relief. These were prescribed
using the Intuitive Colorimeter. Since LH has worn the
spectacles, she has found a decrease in the frequency of the
migraines by 60%, with none severe enough to confine her to
bed. She has also been able to reduce the dosage of
medication. She has now been using the spectacles for
approximately nine months. Previously, she had worn
commercially available sunglasses, but had not obtained the
same reduction in symptoms. This is a case of confirmed
migraine for which numerous drugs had been tried to give
long-term relief. Relief over an extended period has only
been obtained by the use of precision tinted lenses. It is
concluded that in order to receive relief from migraine
symptoms, the tint may need to be individually prescribed
and tightly defined.

Dr. Garrison and colleague Kathleen Saathoff
of San Jacinto Methodist Hospital in Baytown, Texas,
presented the results of a case series of 33 patients with a
history of photophobic headache who were offered bilateral
insertion of special-order red-tinted contact lenses during
acute pain attacks. The light-filtering lenses brought
immediate pain relief to 31 of the patients.
