Astigmatism
Astigmatism is the optical term for more than one point of focus. It occurs when the surface of the or cornea crystalline lens is not spherical. Light from an object does not focus exactly on the retina but at two separate points. An astigmatic eye has curves that are steeper in one direction than the other. An example of this could be where the cornea is not spherical and shaped more like a Rugby ball than football - of course this is not noticeable by just looking at someone's eyes.

As a result, the eye is unable to focus a point or object into a sharp focused image on the retina. This can cause eye strain, head aches, tired eyes, migraines and many other symptoms. Astigmatism can be corrected by glasses or toric contact lenses available at any Caskie Opticians branch.
