Focal length - Wikipedia

WebIf you have myopia or nearsightedness, you would use diverging lenses (concave) to shift the focus of your eye lens backwards so that it can focus on the retina. Just the opposite goes for hypermetropia or farsightedness, in which you would use converging (convex) lens to bring the focus closer. In astigmatism, you would use cylindrical lenses. WebIt can be shown that the lens focal length is related to the distance between different Moiré images. According to the author, this method gives the focal length value with less than 1% accuracy. 7.
