The eyes of living immersed herring and silversides are farsighted and require greater hypermetropic correction for lateral vision than for anterior vision. Comparisons of lens-to-retina distances in frozen material with focal lengths of lenses are consistent with the degree of hypermetropy found by retinoscopy.
