| spherical aberration |
occurs when a lens is ground perfectly spherical causing light rays to fall at different points on the macula where by a common focus can not be achieved.

| spherical aberration |
A problem where a lens or mirror in a telescope is not shaped correctly, so the light from the center is focused at a different location than the light from the edges. You should never have to worry about this. This only shows up in really cheap telescopes. Editorial Note: Not always. Spherical aberration is one of the commoner flaws in relatively inexpensive reflectors of otherwise competent design.

A parabolic mirror will focus incoming light to a single point. A spherical mirror will focus incoming light to different points causing stars to no longer appear as nice round points of light. This distortion is called spherical aberration.
