Synopsis
Excerpt from Eyes and Spectacles
AN attempt has been made in the accompanying book to bring together the most important points about spectacles. In the modern science of spectacles the chief importance must be laid upon vision with moving eyes (looking about); it was therefore necessary to con sider in the first place the eye itself, and also perspective as a form of perception by means of which the arrange ment in space of the outer world became manifest to the observer. This is dealt with by the introduction of the perspective bundle of rays with its apex at the centre of rotation of the eye, and is further more clearly ex plained and illustrated by means of an assumed - gener ally plane - projection surface.
