patients with migraine have shown that it is only when the shade of coloured
spectacles is precisely chosen for optimal comfort that a reduction in an
otherwise abnormally large blood oxygenation occurs. Given the general association between elevated cortical blood
oxygenation and visual discomfort, this tends to support other evidence that
a precise shade may be necessary for a beneficial
clinical effect. Declaration of interest: The
