WebOct 19, 2015 · Corrective lenses, either spectacle lenses or contact lenses, can be spherical like a baseball, where all radii from the center are the same length. Alternately, lenses may be cylindrical like a pop can. If you split a pop can vertically down the middle, you will have a flat side and a curved side. The flat side has no power.

WebCylinder lenses are similar to spherical lenses in the sense that they use curved surfaces to converge or diverge light, but they have optical power in only one dimension and will not affect light in the perpendicular dimension. This is impossible to accomplish using spherical lenses as light will focus or diverge uniformly in a rotationally symmetric manner.

WebMay 5, 2010 · A cylinder curve is curved along a single axis and flat along the perpendicular axis. Furthermore, while the focus of a spherical curve is a single point, the focus of a cylinder curve is a line. The meridian along which there is no cylinder power in the lens and consequently the meridian of the cylindrical focus is the cylinder axis.
