The M system correction lenses provide this, and they also make composing images in the viewfinder more comfortable than it can be with eyeglasses. These lenses are available in grades of plus/minus 0.5, 1, 1.5, 2 and 3 diopters. Prior to ordering, it should be noted that the Leica M's viewfinder is preset by default to -0.5 diopters.
