Seeing and perception
The majority of the information that we receive about the world around us comes through our eyes. Light is not only an essential prerequisite , it is the medium by which we are able to see. Through its intensity, the way it is distributed and through its properties, light creates specific conditions which can influence our perception. Lighting design is, in fact, the planning of our visual environment. Good lighting design aims to create perceptual conditions which allow us to work effectively and orient ourselves safely while promoting a feeling of well-being in a particular environment. At the same time it enhances the environment in an aesthetic sense.
