This variation in the curvature of the lens surface gives a great reduction in distortion, especially at the edges of the lens. Aspherical lenses permit optimum freedom from distortion at a precisely determined eye distance. Since the individual colours of the spectrum are refracted to different extents, the images display coloured edges. This can be avoided by employing an achromatic lens pair, theAchromatlcs. This ensures a true colour image. 211
