Presentation transcript:

The Vision Test Step 1: Have your nose approximately 1.5 feet from the screen. (Slightly closer than normal distance when working at a computer.) Step 2:Cover one eye and read the entire paragraph without moving your head. Step 3:If the words get fuzzier as you read, it is an indication of an astigmatism. If you can read the entire paragraph clearly then no astigmatism is present in that eye. Try again with the other eye. Good luck! Click here to begin:

Astigmatism is characterized by an irregular curvature of the cornea. This type of disorder is also known as a refractive error. Astigmatism occurs in nearly everybody to some degree. For significant curvature, treatment is required. A person's eye is naturally spherical in shape. Under normal circumstances, when light enters the eye, it refracts evenly, creating a clear view of the object. However, the eye of a person with astigmatism is shaped more like a football or the back of a spoon. For this person, when light enters the eye it is refracted more in one direction than the other, allowing only part of the object to be in focus at one time. Objects at any distance can appear blurry and wavy.
