A microscope (16) with a flexible fiber-optic cable (14) used as a scanner is provided to assist the vision of people; particularly to enable persons with vision defects to read. The eyepiece (32) of the microscope spreads the enlarged images onto the functional portion of the retin a of the users eye (20). A lenticular screen is used as a diffuser in the microscope. The person moves one end of the fiberoptic cable (14) along the material (18) to be viewed in order to scan it. The flexibility of the fiberoptic cable facilitates the scanning motion. The character images are broken up into small segments by the fibres. In each segment the light intensity is substantially the average of the light received by that fiber of the bundle. Thus, confusing background details of the paper, etc, on which the matter is written, are substantially subdued or eliminated.
