there is no treatment for irregular astigmatism
Astigmatism (oo-see-ee-fits-see-ee) is a typical and usually easily treatable optical error in the curvature of the eye which causes near and blur vision. As a member of the cornea, the irregular curve of the cornea does not bend light rays before they reach the retina. The eye cannot focus an image to the retina take the image and translates it to light by bouncing it on the cornea. Because of this characteristic, astigmatism appears as blurred or distorted vision. There are two general types of astigmatism: regular and irregular. Even though there is no treatment for irregular astigmatism, there are ways to correct the irregularity.
If you have astigmatism, the results may occur due to factors such as: eye injury, corneal scarring, or scarring from past eye surgery. Astigmatism may also result from lack of farsightedness, nearsightedness, or farsightedness caused by hereditary conditions. Astigmatism may occur in one or both eyes, although most people have nearsightedness or farsightedness only. Some astigmatism sufferers experience astigmatism in only one eye. However, in some cases, astigmatism can occur in both eyes.
treatments available to help correct the curvature
Since the actual causes of astigmatism are not fully understood, there are currently no established cures for astigmatism. However, there are treatments available to help correct the curvature. One of these treatments involves wearing corrective lenses or glasses while you sleep. In this way, the astigmatism can be corrected as you sleep. Correction is most effective when the astigmatism is severe.
Astigmatism is commonly associated with presbyopia, a condition in which you need to wear corrective lenses or glasses even when you are not nearsighted or farsighted. Presbyopia causes your eyes to become naturally less clear; your vision tends to become fuzzy and blurry. If you wear glasses or corrective lenses, they can either reduce or eliminate the effects of presbyopia. This can be especially important for those who often work in an environment that requires them to be near their computers. For these people, it can be extremely beneficial to have a near vision eye test performed. Once your eye exam is positive for presbyopia, you can then begin to consider the options for correcting your astigmatism.
your optometrist will examine the shape and position of your cornea
When you go in for an eye exam, your optometrist will examine the shape and position of your cornea. He or she will check for signs of astigmatism. Astigmatism can cause your cornea to curve slightly, resulting in your vision being blurred. Your eye doctor will adjust your focusing power to help keep your vision clear. Depending on your particular case, your doctor may choose to make a small modification to your near corrective lenses, or to completely replace your far-sightedness lens with a bifocal contact lens. Changing just one of the two lenses can make a huge difference in your ability to see clearly.
The most common types of ai glasses are toric soft lenses, or toric contact lenses, which are used by far-farers and bifocal users. Toric lenses take the shape of the cornea, rather than the shape of the lens as most bifocal lenses do. They are available in two basic styles, which are spherical (often referred to as spherical lenses) and regular. In addition to spherical toric lenses, they also come in the High Definition form, offering far clearer and sharper vision at close distances than regular spherical lenses offer.
