It images a point source into a line along the optic axis, or transforms a laser beam into a ring.

This occurs when the pupils are not exactly centred on the optic axis, so the lens acts as a prism.

The surface becomes smooth along the rubbing direction and the LCD's optic axis aligns along the rubbing direction.

In third-order astigmatism, the sagittal and transverse rays form foci at different distances along the optic axis.

Those sections are most useful which are perpendicular to an optic axis, and consequently remain dark on rotation.

In order to make LCDs work, companies have aligned liquid crystal molecules with the optic axis in liquid crystal displays.

In a liquid crystal it is the rotation of an optic axis called the director that produces the functionality of these compounds.
From the en.wikipedia.org
Sections perpendicular to an optic axis of a biaxial mineral under the same conditions show a dark bar which on rotation becomes curved to a hyperbolic shape.
