Spherical Aberration, Q factor & choice of IOL

WebAberration . Spherical aberration. Converging mirrors are often sections of a sphere, rather than parabolic. The sphere has the advantage that any normal to the mirror is an axis, so it is not important to align the axis with the object. The disadvantage is that a sphere does focus parallel light to a single point.
