“…Seizures and headaches are most likely when the flicker is between 15 and 20 Hz. 38 Flicker in this frequency range is sometimes produced when 50 Hz compact fluorescent lamps ignite (author's measurements). If these lamps are used in public places with occupancy sensors, they ignite automatically without warning and constitute an unacceptable hazard.…”

Visual discomfort occurs when the statistics of the retinal image depart from those of natural scenes, particularly in respect of an excess energy at spatial frequencies close to 3 cycles/degree. Computer models suggest that uncomfortable stimuli are processed with a larger and less sparse neural response. Uncomfortable stimuli usually evoke a relatively large oxygenation of the visual cortex of the brain, consistent with inefficient neural encoding. The discomfort may be homeostatic. The neural computation that sustains sight is therefore likely to be more complex when the visual scene is spatially periodic, when the colour contrast is high or when saccadic suppression is impaired by flicker that is too rapid to be seen.

“…The stimuli evoke high-amplitude electrical signals from the scalp (Plant et al, 1983) and large blood oxygenation dependent signals during functional magnetic resonance imaging (Huang et al, 2003). They induce perceptual distortions and, in those who are susceptible, migraine (Huang et al, 2003) and seizures (Wilkins et al, 1980). Binnie et al (1985) showed that, in patients with photosensitive epilepsy, gratings that drift continually towards fixation can be fixated stably, but do not evoke epileptiform paroxysmal EEG activity: they are not epileptogenic.…”

a b s t r a c tWe review the concept of visual stress and its relation to neurological disease. Visual stress can occur from the observation of images with unnatural spatial structure and an excess of contrast energy at spatial frequencies to which the visual system is generally most sensitive. Visual stress can often be reduced using spectral filters, provided the colour is selected with precision to suit each individual. The use of such filters and their effects on reading speed are reviewed. The filters have been shown to benefit patients with a variety of neurological conditions other than reading difficulty, all associated with an increased risk of seizures.

Migraine is a common, chronic, multi-factorial, neuro-vascular disorder typically characterised by recurrent attacks of unilateral, pulsating headache and autonomic nervous system dysfunction. Migraine may additionally be associated with aura; those focal neurological symptoms that may precede or sometimes accompany the headache. This review describes the optometric aspects of migraine headache. There have been claims of a relationship between migraine headaches and errors of refraction, binocular vision anomalies, pupil anomalies, visual field changes and pattern glare. The quality of the evidence for a relationship between errors of refraction and binocular vision and migraine is poor. 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.
