| optical aberration |
Aberration in optical systems (lenses, prisms, mirrors or series of them intended to produce a sharp image) generally leads to blurring of the image. It occurs when light from one point of an object after transmission through the system arrives in different points. Instrument-makers need to correct optical systems to compensate for aberration. The articles reflection, refraction and caustic discuss the general features of reflected and refracted rays. ...

| optic atrophy |
Optic atrophy is a pathological term and somewhat misleading. The term optic neuropathy is often used instead. In medicine, atrophy usually means shrunken but capable of regrowth. Optic atrophy means that on microscopic examination most of the fibers of the optic nerve are degenerated (dead). The optic nerve is part of the brain and has no capability for regeneration. ...
