Abstract
A method of assessing the effect of viewing varying colours of light on a subject's perception of tinnitus, comprising the steps of: presenting a display in at least part of the subject's field of view; illuminating the display with coloured light in the visible spectrum using one or more variable sources, varying measurable values of the coloured light illuminating the display; and recording the measurable values of the coloured light illuminating the display at which the subject indicates a change in their perception of tinnitus. Also provided are methods of determining which tristimulus values of light can be used to alleviate a subject's perception of tinnitus, methods of producing data sets of measurable values of coloured light, use of coloured light, articles formulated to modify illumination of at least part of the visual field of a subject, a method of alleviating a subject's perception of tinnitus and use of apparatus for assessing the effect of viewing varying colours of light on a subject's perception of tinnitus.
