Other Potential Clinical Uses of Precision Tinted Lenses

In this chapter we review studies in which precision tints have been used in a variety of neurological disorders, including photosensitive epilepsy, autism, migraine, cluster headache, visual snow, stroke, multiple sclerosis and concussion (mild brain trauma). Whilst the evidence regarding these topics is preliminary and indicative, the effects of coloured filters in these conditions may help to further elucidate the mechanisms underlying the benefit from colour. In particular, the extent to which these findings provide convergent support for the cortical hyperexcitability hypothesis is discussed.
