Abstract
An optical device for focusing images on the retinas of the left and right eyes of a human user, containing left and right corrective lenses each having a light receiving surface and first and second lens segments of different focal lengths for focusing near and far objects respectively. The boundary between the first and second segments of each of the lenses extends in the same direction and parallel to the light receiving surface, and the lenses are supported and oriented with respect to the eyes of the user so that the boundary is substantially perpendicular to a line connecting the eyes of the user, and so that each first lens segment occupies a nasal position with respect to the user's eyes and each second lens segment occupies a temporal position with respect to the user's eyes.
