Are you referring to astigmatism, which is an eye condition in which the lens of the eye is malformed (not perfectly spherical) and makes the person afflicted often feel as though they see the world as though its under water...
The cornea, the front surface of the eye, is not curved properly with a person with astigmatism. This is fairly common and not contagious. It is usually congenital. It can occur in babies born prematurely and those born with a low bodyweight.Surgeries, eye injuries that cause scarring of the cornea may cause astigmatism. Also, Diabetes and a degenerative disorder of the eye can cause the curve to become irregular.
Astigmatism is caused by irregularity in the curvature of the cornea, or lens, of the eye. It causes vision to be blurred, and can be easily corrected with prescription glasses or contacts.
Some effects of astigmatism are headaches, blurred vision, and limited vision after dark. Other effects include squinting and irritation of the eyes.
This disorder really has no function. It is seen in 1/3 of the population and vision is "blurry". Glasses to correct this are necessary.
the defective curvature on the cornea or lens is called Astigmatism

Astigmatism is a medical condition. One in a million patients have it.
The main symptom of astigmatism is blurring
Astigmatism is a condition that may be present at birth
The astigmatism chart was designed to evaluate whether a person has astigmatism, which is a condition which results in blurry or distorted vision. When a person looks at an astigmatism chart, all lines should appear to be the same darkness, clarity, and distance apart. A person with astigmatism will notice differences in the lines.
However, in astigmatism the cornea is elliptically shaped, more like a football
no that is not true my mother has astigmatism and she has contact lens'.
No, an astigmatism can not correct itself. This is because an astigmatism is caused by the shape of the eyeball.
Astigmatism can be most simply treated with either eyeglasses or contact lenses.
An astigmatism means that the shape of the optics cause the focus to be a line rather than a point (the lenses are not spherical). Thus the image produced by these lenses is imperfect, causing a blurred image/vision.
Ametropia means any type of refractive error, such as nearsightedness or astigmatism.
