At the present time, positive, wide-angle contact (and preset) lenses, having a large field of view, are widely used for inspecting and irradiating the fundus. They provide a real, inverted image of the fundus, but illuminate only the slit projected. The wide-field they provide (125 degrees ) is considered to be an advantage, but their image inversion and the lack of illumination of the whole field is disadvantageous. Contact lenses of the Goldmann type have a comparably restricted field of view (standard Goldmann: 46 degrees, CGR 3: 53 degrees). They illuminate the whole field inspected, but it is necessary to use internal mirrors when looking at the periphery.
