See nearby objects clearly, not distant objects

Diverging (concave) lens with negative power

See distant objects clearly, not nearby objects

Converging (convex) lens with positive power

$\text{power} = \frac{1}{f}$

Dioptres (D), equivalent to $\text{m}^{-1}$

Cornea not spherical; different curvatures in directions

Cylindrical lens

Spherical: point; Cylindrical: line

Angle (1-180°) for cylindrical lens orientation
