Abstract

See full text

A vision assisting apparatus includes a casing for forming an inversely U-shaped optical path, a light entry, provided at one end of the optical path, through which light enters, a light exit, provided at another end of the optical path, through which light exits in an opposite direction to the light entry, an optical system for processing an image entered via the light entry by using the optical pass and outputting a processed image via the light exit, and attaching structure for attaching the casing to a wearer so that the light exit is positioned close to an eye of the wearer. By forming the inversely U-shaped optical path with the casing, it is possible to provide a sufficiently long optical path in a compact form. Accordingly it is possible to provide the vision assisting apparatus that does not hide facial expressions, is easy to use, and can provide a sufficient length for setting a magnifying optical system without extending the distance in the horizontal direction between the light entry and the light exit.
