Cylinder lenses can be concave or convex, as shown below. For the lenses shown, the horizontal meridian looks like a cross-section of a spherical lens and the vertical meridian looks like a plane wedge. The focusing of light in these meridians can be handled by the usual simple

WebTo find the values of x, y, and z in spherical coordinates, you can construct a triangle, like the first figure in the article, and use trigonometric identities to solve for the coordinates in terms of r, theta, and phi. To do this, I find it easier to first find that ϕ is the angle of the triangle opposite the line segment in the xy-plane. WebSphere, often written as SPH, means that the correction for nearsightedness or farsightedness is spherical, equal in all meridians of the eye. It is measured with the unit diopters (D), indicating the lens power of the glasses. The Sphere is also used to correct the nearsightedness or farsightedness.
