Astigmatism is a medical term for a blurred vision that is caused by the irregular curve of the cornea. In this condition light rays will enter the eye not in the right focus on the retina, creating a blurred image. In simple words, astigmatism is an image distortion that is caused by improper shape of the cornea. In the case of more severe astigmatism, everything is blurry at a distance, and it becomes impossible to ignore the condition. People who suffer from astigmatism can have their vision improved by the usage of toric lenses. Regular astigmatism is usually easier to correct. In it, the meridians in which the two different curves are, are located 180 degrees apart.

Procuring a contact for astigmatism used to mean that only rigid lenses or a hard contact lens for astigmatism could be used but now there is a soft contact for astigmatism that can be used. This contact for astigmatism is called a toric lens. Astigmatism is common in moderately high amounts in infants and toddlers. It often self corrects. If it is too high or persists it needs to be corrected by the eye doctor with eyeglasses. In some cases when a very young child is incapable of wearing glasses contact lenses may be used. Most of the astigmatism patients are born with that, which may get worse over time. Eye injuries, improper eye surgeries and keratoconus can also damage the corneal shape. The corneal shape of astigmatism patients is not perfectly spherical. Instead, it likes an oblong football, which causes light rays to focus on two points in the eye back.

It is important to schedule regular annual eye exams because it can worsen over time, so it is necessary to keep a close watch and adjust prescriptions for glasses or contact lenses as needed. Both glasses and contact lenses are usually suitable corrections for an astigmatism. Certain types of astigmatism contact lens have proven to be ineffective. Ineffective lens will not be able to address astigmatism and in some cases, will worsen the condition. A recommended lens for astigmatism is toric contact lens. Astigmatism can be caused by other factors other then the front surface of your cornea being out of round. Astigmatism can be caused by the back of your cornea being misshapen. Your eyes operate on a two lens system; if either lens is out of shape then you will develop astigmatism.

When you feel your eyes are tired, you should take a break. Spend a few minutes to relax your eyes. During the break you can have eye exercise by moving your eyes around. You can also look at the yard or green grass outside. Astigmatism is caused by the cornea being an unusual shape, more like a oblong than a perfect sphere, and a person is either born with it, or it may have been caused by an accident. Glasses correct astigmatism by redirecting the light to the retina. This produces clearer vision for the astigmatism sufferer. Contacts work in a similar way also and are used to redirect the light.
