Abstract
An optical viewer is disclosed which incorporates plastic lenses which reduce the weight and cost of the optical viewer. In accordance with an important aspect of the invention, the optical design of the viewer is configured to compensate for the inferior optical characteristics of the plastic lenses to provide an optical viewer with comparable performance relative to optical viewers with glass lenses.
