How Astigmatism Causes Blurred Vision

Astigmatism is a vision problem characterized by an irregularly shaped cornea. The eye’s natural curvature is like a pin or the back portion of a rugby ball. When light shines on the eyeball, the retina bends light rays so they focus correctly on the retina in the back part of the eye. But when light bends too much, the eyeball does not focus light correctly and that leads to blurred vision. That’s why a person with astigmatism has a blurred vision.

Glasses Or Contact Lenses

If you have astigmatism, you might be given glasses to correct astigmatism. But why should you wear glasses or contact lenses instead of just wearing eye glasses? There are several advantages of having glasses or contact lenses.

One of the advantages of glasses or contact lenses is that they correct astigmatism.

Irregular Astigmatism

The most common form of astigmatism is called bifocals. It is characterized by an irregularly shaped cornea. With bifocals, a thin circle is usually placed above the iris. This circle controls the amount of light entering the eye through the pupil. In addition to irregular astigmatism, some astigmatisms are also characterized by two curves. One is called the hyperopia or the nearsightedness and the other one is called the farsightedness or the astigmatism. A person with the hyperopia has astigmatism because the cornea has slightly more curve than it normally has. And the person with the farsightedness has astigmatism because the cornea has less curve than it normally has.

When light enters the eye through the pupil, it bends on its axis due to the corneal shape. In astigmatism, this corneal shape is not curved like in normal eyes. Instead, the corneal shape is shaped like a basketball. When light comes into the eye through the pupil, it bends on its axis and does not refract on its axis like it normally does.

Cause And Symptoms Of Astigmatism

Astigmatism usually affects people when they are using glasses or contacts. People who use contact lenses are at a higher risk of astigmatism because of the irregularities in the eye’s corneal shape. The symptoms of astigmatism vary widely and their effects on vision are also different from one patient to another. Some people experience severe astigmatism and their only option for treating their symptoms is glasses while others with mild astigmatism can wear contacts to correct their vision.

There are other medical conditions that can cause astigmatism. Some examples are monocular astigmatism, myopia, presbyopia, and astigmatism induced keratopathy. However, research has shown that astigmatism is most common among younger adults and some forms of astigmatism are hereditary. It can also be caused by eye diseases such as glaucoma, cataract, and progressive retinopathy.

Surgery For Astigmatism

If you have astigmatism you should know that your nearsightedness, farsightedness, and astigmatism are separate diseases. They do not go together and will not cause severe damage to your vision if treatment is done correctly. The most common form of treatment is the wearing of glasses or contacts. However, refractive errors can also be corrected with LASIK eye surgery which uses laser technology to reshape the cornea to correct these refractive errors.

Majority Of Astigmatism

The majority of astigmatism is not dangerous, however it does cause discomfort and can interfere with your vision. Astigmatism occurs when the front surface of the eye, called the cornea, contains irregularly shaped curves. As a result of this irregular curvature, light cannot properly reach the retina, causing blurry vision. In addition to the eye being unable to receive adequate light, astigmatism can also cause headaches, eyestrain, and eye fatigue. Some forms of astigmatism are permanent, meaning that they are unable to be corrected naturally, while others are only minor factors in the overall vision improvement of the patient.

Procedures Of Treatment

With regards to treating astigmatism, the first step is to see an optometrist who is trained in the treatment of refractive errors. Your optometrist will examine your eyes and your retina to determine if astigmatism is a factor in your eyesight. If astigmatism is determined to be a factor in your eyesight, your optometrist will design an astigmatism correction treatment regime, usually in the form of glasses or contacts. With regular eye exams, your optometrist will be able to determine if astigmatism is causing your eye problems, and prescribe corrective measures.

Another effective form of treating astigmatism is the use of interventional procedures. Such procedures are often used to correct refractive error caused by astigmatism. One example of an intraocular lens exchange is a myopia correction eye surgery. During myopia refractive lens exchange surgery, a contact lens is placed into one eye and a toric contact lens is placed into the other eye. The toric contact lenses provide better astigmatism correction than the myopia contacts, due to their larger diameter. Typically, a patient only needs one eye to undergo this procedure.

While many patients may choose to undergo refractive surgery or astigmatism correction surgery on their own, more patients benefit from the help of an expert. An expert optometrist has completed both medical and surgical training in order to perform these tasks effectively. In addition to having gained hands-on experience with the many different techniques that correct eye problems, an eye care professional has extensive skill and knowledge in dealing with refractive surgery risks. This includes the prevention of any eye infections that can occur as a result of refractive surgery, as well as removing any tissue that may develop in the eye after the procedure has been performed.
