What is Astigmatism?
Astigmatism is a condition caused by the irregular curvature of the cornea or lens, leading to blurred or distorted vision. This irregular curvature prevents light from focusing properly on the retina, resulting in blurry or distorted images.
What Causes Astigmatism?
Astigmatism is usually a congenital condition and is often associated with genetic factors. However, it can also develop due to irregularities on the corneal surface or eye injuries. The loss of the cornea's ideal curvature causes light to refract unevenly on the retina, which is the main cause of astigmatism. Natural changes in the cornea over time can affect and worsen the condition.
How Does an Eye with Astigmatism See?
It is important to understand the visual experience of individuals with astigmatism. People with astigmatism often experience blurred vision at both near and far distances. This makes it difficult to see straight lines or small details clearly. During night driving, they may see halos or circular light rings around lights or experience light scattering. Those with astigmatism may also experience headaches and eye strain when reading or focusing on objects without corrective lenses.
What Are the Symptoms of Astigmatism?
Understanding the symptoms of astigmatism is crucial for early diagnosis and appropriate treatment. The most notable symptom of astigmatism is blurred or distorted vision. Eye strain and frequent need to rub the eyes, especially after activities requiring prolonged visual focus, are common. Headaches, often concentrated around the eyes, and discomfort such as burning or itching in the eyes are also common. Inability to see clearly at near or far distances and increased difficulty with reading or computer use are typical signs of astigmatism.

How Is Astigmatism Treated?
Treatment for astigmatism includes various methods aimed at correcting refractive errors in the eye. Glasses or contact lenses can be designed to correct astigmatism, ensuring that light focuses properly on the retina and enhancing visual quality. However, these are not permanent solutions.
For those seeking permanent improvement in visual quality, eye surgery may be considered. Laser eye surgeries such as LASIK, PRK, and LASEK aim to permanently correct astigmatism by reshaping the cornea.
How Much Does Astigmatism Treatment Cost?
The cost of astigmatism treatment varies depending on factors such as age, the severity of astigmatism, and overall health. Your eye doctor will conduct a comprehensive eye examination to determine the most suitable treatment method for you. Choosing the right treatment option should be based on personal needs and lifestyle.
