Light conditions and brightness play a major role in how a person with low vision perceives their environment. There are many types of lamps, from standing to portable, battery-operated or pivoting that can be used according to activity.
It’s essential to optimize, wherever possible, the brightness of an environment to maximize residual visual function. Particular attention should be paid to:
– Avoid all dazzling light sources.
– Arrange blinds and curtains to reduce the variation in natural lighting.
– Ensure an ambient lighting that’s as uniform as possible between the different spaces where the person will be moving to avoid areas of shadow.
– Brighten workspaces with desk lamps.
– Choose the color and intensity of the light source required for the optimal visual efficiency of the person concerned according to their visual needs.
Lamps in different color temperatures can provide the most adapted and comfortable lighting:
– Incandescent lamps: emit a warm light (mainly red).
– Fluorescent lamps: emit more blue light.
– LED lamps: emit a cold light (predominantly blue).
