Lighting

This refers to either natural or artificial light both inside buildings and outside. The amount and direction of light are important for best visual functioning. The light is best coming from behind the person with low vision. People have different needs for lighting, but generally good light is best. The amount of light, however, cannot always be changed. A person can move to different positions to alter the amount of light from direct sunlight to shade or from a shady to a bright position. Covering the head or eyes can provide shade. Also consider the use of sunglasses.

Does the person work better in bright light or in the shade? Does the person try to shade the eyes with a hat or a hand or turn from the sun? Inside, can the person work better where there is light from a door or window? Is there any difference in how the person can move around when it is dark, compared with in the light?

Is vision severely affected by a change from bright to dull light or from dull to bright light?
