It is important to have proper illumination or lighting for the disabled and elderly to ensure that they have an easy time seeing while walking or reaching certain things.
Even light across the room can help to reduce the glare and cut down on vision difficulties.
Increase ambient light levels such as chandelier which help to disperse light all around the room.
Cooler light such as halogen bulbs and fluorescent bulbs, can help add to the ability of older eyes to distinguish colors.
Using large switch or sensor type can reduce the burden to switch on / off lamp.
Help people in wheelchairs to see properly so that they can navigate their home.
Prevent older people from falling off as they are very sensitive to glare, which can cause them to miss obstacles in their path.
Entrances to buildings should be particularly well-lit during the day and dimly-lit at night, to enable the eye adapts to the light/dark transition.

Good task lighting over sink, stove and other work areas.
