<P> In optics , chromatic aberration ( abbreviated CA ; also called chromatic distortion and spherochromatism ) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point . It occurs because lenses have different refractive indices for different wavelengths of light . The refractive index of transparent materials decreases with increasing wavelength in degrees unique to each . </P>
