Why are prisms (optics) used in spectacle prescriptions?
I know it's to correct squints but is there any other reason?
Prisms are used in spectales since they bend light rays in such a way as to correct the vision of the wearer. There are two basic kinds of lenses - concave and convex. Concave lenses bend light rays apart and are used by short-sighted people, whereas convex lenses bend light inwards and are used by long-sighted people. The basic principle is that someone with defective vision has an eyeball that is too long or short, so light rays focus in front of or behind the retina. By using the appropriate lens, the light rays can be focussed on the correct part of the eye - the retina.
