Astigmatism is a common eye condition that affects the way light enters the eye. It is a refractive error that occurs when the cornea has an irregular shape. Unlike normal eyes, which have a spherical shape, the cornea with astigmatism is shaped more like a football.Astigmatism can occur in combination with myopia or hyperopia. It can affect people of all ages. While the exact cause of astigmatism is unknown, it is believed to have a genetic component. In some cases, astigmatism may be present at birth or develop as a result of an eye injury or surgery.
How Astigmatism Affects Your Vision
Astigmatism affects vision by distorting the way light enters the eye. The irregular shape of the cornea or lens causes light to focus on multiple points instead of a single focal point on the retina. This results in blurred or distorted vision at all distances.Individuals with astigmatism may experience difficulties with both near and distance vision. They may find it challenging to read small print or see objects clearly from a distance. Additionally, astigmatism can cause eyestrain and headaches due to the increased effort required to focus on objects.
Diagnosing Astigmatism
Astigmatism can be diagnosed through a comprehensive eye examination performed by an optometrist. During the examination, the doctor will evaluate the shape of the cornea and the clarity of vision. Several tests may be conducted, including a visual acuity test, a refraction test, and keratometry.In a visual acuity test, the doctor will ask you to read letters from an eye chart to determine your ability to see clearly at various distances. A refraction test involves looking through a series of lenses to determine the prescription needed to correct your vision. Keratometry measures the curvature of the cornea, allowing the doctor to assess the degree of astigmatism.
Treatment Options For Astigmatism
Fortunately, astigmatism can be effectively managed with various treatment options. The most common treatment for astigmatism is the use of corrective lenses, such as glasses or contact lenses. These lenses are specially designed to compensate for the irregular shape of the cornea or lens, allowing light to focus properly on the retina.For individuals who prefer not to wear glasses or contact lenses, other options exist. Refractive surgery, such as LASIK or PRK, can correct astigmatism by reshaping the cornea. These surgeries use lasers to remove precise amounts of corneal tissue, resulting in improved vision.It is important to consult with an optometrist to determine the best treatment option based on your specific needs and lifestyle.
