10 Common Eye Diseases
Eye Disease #3: Astigmatism
As the light we see is projected onto the retina at the back of the eye, it needs to be in focus for us to be able to see it clearly. Just try watching a movie from a projector that is out of focus and you will struggle to see what is happening. The correct focusing of this light is helped by the cornea, which is found at the front of the eye.
Astigmatism is a condition that causes the shape of the cornea to become irregular. This affects its ability to focus light clearly and the patient can begin to experience blurred vision as a result. As the patient continuously strains to try and gain focus, they are also likely to experience headaches. Spectacles or surgery might be needed to correct the condition.
