Understanding your Refractive Condition
Clear vision is a result of light passing through a perfectly shaped eye so that it focuses clearly on the retina. Abnormal focusing conditions of the eye are called refractive errors and consists of the following:

		Normal Vision
		Nearsightedness: Nearsightedness occurs when the cornea is too curved or the eye is too long. Light passes through the eye but focuses before it reaches the retina causing blurred distance vision.
		Farsightedness: Farsightedness occurs when the cornea is too flat in relation to the length of the eye. Before the light has covered enough distance to focus, it reaches the retina causing blurred near vision and often blurred distance vision.
		Astigmatism: Astigmatism occurs when the Cornea is abnormally shaped like a football. When light passes through the cornea, it focuses in more than one place relative to the retina causing blurred and distorted vision near and far.
