It is important that this is recognized - to prevent people becoming confused. Do the tasks chosen help in the development of other skills. Life can be made much easier for many people with visual disabilities by helping them use what sight they have, and their other senses, usually hearing and touch. Lighting - good background lighting is important. Close work may need lighting from behind.
Glare is very distracting.
People may be able o move about in poorly lit areas, but not cope with glare which makes them totally blind. Contrast - colour contrast helps people use their sight. It enables people with low vision to see and find things -e.g, a brown door against a white wall. It is also useful at meal times - bright cutlery and crockery on different colour contrasting plain tablecloths. Noise - background noise from T.V, radio or music may mask other sounds, like the footsteps of an approaching person.
