"Axis" is a term most often used in describing the orientation of Astigmatism. If you look at your written eyeglass prescription, it may say something like "-2.00-1.00X180". What this means is that you have two diopters of myopia (nearsightedness) and one diopter of astigmasim at axis 180. Axis 180 tells you that the orientation of the astigmatism correction is horizontal. Axis 90 would be Vertical. Axis 045 or 135 would be oblique. And it could be any axis from 1 to 180 degress. The degree of the axis depends on the type of astigmatism you have.
In eyesight, the term "axis" refers to the orientation of astigmatism, which is a refractive error that causes blurry vision. The axis is measured in degrees and indicates the direction of the irregular curvature of the cornea or lens that is causing the astigmatism.
The Axis was the alliance among Germany, Italy, and Japan.
