Lighting for de-generative eye conditions

Abstract

Increasing lighting levels is frequently discussed as an effective means of enhancing the remaining vision of people who are partially sighted. Lighting is however a multi-dimensional phenomenon that relies on the interaction of a number of variables including: illuminance, luminance, colour, contrast, object size, spatial dimensions, surfaces and the human visual system. The research will focus on the quantitative and qualitative aspects of lighting and the lighting types in relation to people with de-generative eye conditions. It is based on a review of the general lighting and vision impairment literature. Whilst there are many similarities between the recommendations for normally and partially sighted individuals, there are also significant differences that require further investigation.
