Spherical lenses suffer from spherical aberration because they don't focus parallel lines. Instead, parabolic lenses will focus parallel lines to the focus of the parabola. However, even parabolic lenses have a problem with focusing light that is not parallel to the axis of the lens, suffering from a different kind of aberration called a coma: https://en.wikipedia.org/wiki/Coma_(optics)
