Astigmatism in only one eye may cause lazy eye (amblyopia) if present from birth. The affected eye does not 'learn' how to see because the brain ignores the signals it receives. Amblyopia can be treated with eye patching if diagnosed early enough, before the vision pathways in the brain are fully developed.
Astigmatism is a common eye condition that's usually corrected by eyeglasses, contact lenses, or surgery. Astigmatism is caused by an eye that is not completely round and occurs in nearly everybody to some degree.For vision problems due to astigmatism, glasses, contact lenses, and even vision correction procedures are all possible treatment options.A person's eye is naturally shaped like a sphere.Under normal circumstances, when light enters the eye, it refracts, or bends evenly, creating a clear view of the object. Refractive surgery. 2  Another method for correcting astigmatism is changing the shape of the cornea through refractive or laser eye surgery. 3  While there is more than one type of refractive surgery, specific treatments are recommended on an individual basis.
