The surface of the cornea is shaped more like a football instead of round like a basketball and the eye is unable what to do for new years eve 2014 focus light rays to a single point.
In this case, vision becomes out of focus at any distance. In addition, the curvature of the lens inside the eye can change, resulting in an increase or decrease in astigmatism. This change frequently occurs in adulthood and can precede the development of naturally occurring cataracts. Astigmatism frequently occurs with other vision conditions like myopia nearsightedness and hyperopia farsightedness. Together these vision conditions are referred to as refractive errors because how to make paper hearts easy affect how the eyes bend or "refract" light.
A doctor of optometry can diagnose astigmatism through a comprehensive eye examination. Testing for astigmatism measures how the eyes focus light and determine the power of any optical lenses needed to improve vision.
With the information from these tests, a doctor of optometry can determine if the patient has an astigmatism. The doctor will use these findings—combined with those of other tests performed—to determine the power of any lens correction needed to provide clear, comfortable vision. Once testing is complete, the doctor can discuss treatment options. Since astigmatism is an abnormality of the regular anatomy of the eye, there is nothing that can be done to prevent it from occurring.

By focusing astigmatlsm circle of light on the cornea and measuring its reflection, it is possible to determine the exact curvature of that area of the cornea's surface. This measurement is particularly critical in determining the proper fit for contact lenses.

Using an instrument called a phoropter, your doctor places a series of lenses in front of your eyes and measures how they focus light.

Despite improved technology, patient input remains integral in determining vision needs. Treatment Eyeglasses. People with astigmatism primarily choose eyeglasses to improve their vision.
The eyeglasses contain a special cylindrical lens prescription that compensates for astigmatism. This provides additional power in specific parts of the lens. Generally, a single-vision lens is prescribed to provide clear vision at all distances. However, patients over age 40 who have presbyopia may need a bifocal or progressive addition lens.
Contact lenses. Some people will have better vision with contact lenses rather than eyeglasses. Contact lenses may provide a clearer vision and a wider field of view. However, since contact lenses are worn directly on the eyes, they require regular cleaning and care to safeguard eye health. Standard soft lenses may not be effective in correcting astigmatism.
Special toric soft contact lenses can correct for many types of astigmatism. Because rigid gas-permeable contact lenses maintain their regular shape while on the cornea, they can compensate for the cornea's irregular shape and improve vision for people with astigmatism. Orthokeratology ortho-k involves the fitting of a series of rigid astigmatlsm lenses to reshape the cornea. The patient wears contact lenses for limited periods—such as overnight—and then removes them.
People with moderate astigmatism may be able to temporarily obtain clear vision without minecraft how to give mobs names for most of their daily activities. Orthokeratology does not permanently improve vision. If patients stop wearing the retainer lenses, their vision may return to its original condition. Laser and other refractive surgery procedures. PRK removes tissue from the superficial and inner layers of the cornea.
LASIK removes tissue only from the inner layer of the cornea. If you have astigmatism, you have a wide range of options to correct your vision problem.

The more firm the muscles, the more the muclses will be contracting the cornea and reshape itself. Use your brains guys. All muscles change shape depending on the strengthing of the muscles.
