Beyond 'blur': Image quality shapes eye growth, but limited criteria apply

than the feedback system, since our sense of blur depends on both local spatial alignments and information across a range of different spatial scales in images. Therefore, the feedback system, which is basically restricted to the eye itself, uses much simpler information than that required by the brain to detect and discriminate image blur. The fact that the eye-growth feedback system uses more primitive information means that images of low contrast are just as effective as blurred images at initiating growth, a conclusion that may have implications for the development of myopia (i.e., short sightedness).
