Have you ever wondered if when one sensory module is impaired, other sensory systems learn to develop other means to counteract that deficiency? Past studies have shown that deaf individuals have a larger capability to focus on simple visual stimuli in the parafovea. The parafovea is a region in the eye that surrounds your fovea, the central pit of the eye that is responsible for sharp, central vision. Large rates of Macula_lutea.svgilliteracy in the deaf population have caused people to question whether deaf individuals wide range of focus in the parafovea, causes reduced processing in the fovea. A recent study done at the University of California San Diego has shown that deaf people’s parafoveal vision does not cause reduced vision on the fovea and they actually have a wider range of sharp vision which researchers found and can actually aid them in complex visual tasks such as reading (Bélanger et al. 2012).
