This chapter focuses on different types of low vision and their effect on perceptual cognitive abilities, and examines studies on spatial imagery capabilities of people with blurred vision. It discusses studies which reveal the possibility that inter-sensory compensatory mechanisms differ in people with partial visual impairment and people who are totally blind. Studies conducted on six people reveal that low vision does not restrict people from generating visual presentations similar to their familiar environments. The chapter presents a study which investigates the association of monocular blindness with visual perception along with the effects that binocular deprivation has on basic visual functions.
