ASTIGMATISM!!!

please go away!  I really hate it when my astigmatism attacks. It makes me feel dizzy and makes me vomit. This is one of the reasons why I resigned at the Call Center aside from working on graveyard shifts. I just couldn't stand working infront of the PC for 10 straight hours.  I made a research on the definition, symptoms and treatment of astigmatism just to give you an idea of what I am talking about.

What is Astigmatism?

Astigmatism is an affliction of the eye, where vision is blurred by an irregularly shaped cornea. The cornea, instead of being shaped like a sphere, is more oval-like and reduces the cornea's ability to focus light. Astigmatism is a refractive error of the eye in which there is a difference in degree of refraction in different meridians. So, rather than the surface topology of the eye being spherical, it has two curves, one steeper than the other, in a similar way to the shape of an oval. The condition is typically characterized by an aspherical, non-figure of revolution cornea in which the corneal profile slope and refractive power in one meridian is greater than that of the perpendicular axis. Astigmatism causes difficulties in seeing fine detail, and can often be corrected by glasses with a cylindrical lens (i.e. a lens that has different radii of curvature in different planes), contact lenses, or refractive surgery.

What are the Symptoms?

Although mild astigmatism may be asymptomatic, higher amounts of astigmatism may cause symptoms such as blurry vision, squinting, asthenopia, fatigue, or headaches.

How is it Treated?

Astigmatism may be corrected with eyeglasses, contact lenses, or refractive surgery. Various considerations involving ocular health, refractive status, and lifestyle frequently determine whether one option may be better than another. In those with keratoconus, rigid gas permeable contact lenses often enable patients to achieve better visual acuities than eyeglasses. If the astigmatism is caused by a problem such as deformation of the eyeball due to a Chalazion, treating the underlying cause will resolve the astigmatism.
