The problems faced by developing countries for low vision assessment and training include the size and distribution of the population in relation to available resources, the lack of appropriate assessment materials, and lack of skills and knowledge in the assessment and rehabilitation of low vision. This paper reports on tests and assessment procedures which have been designed utilising technology appropriate to developing countries. Manuals include information on low vision and suggestions for a vision training program. Together these form a multi-purpose kit. Relevant parts can be selected for screening, identification of children with low vision, a comprehensive assessment of functional vision, or a short assessment for a particular purpose such as mobility. The kit has been used and evaluated in many parts of the developing world to ensure its appropriateness.
