Spherical lenses suffer from both spherical and chromatic aberration. Spherical aberration occurs because the lens has a spherical surface, causing light rays that strike the lens near its edge to be focused at a slightly different point than those that strike near the center. Chromatic aberration happens because different wavelengths of light are refracted by different amounts, leading to a dispersion of colors.
