Astigmatism is a common refractive eye condition that affects how light enters the eye, causing blurred or distorted vision at all distances. It occurs when the cornea or lens has an irregular shape, preventing light from focusing properly on the retina.
What Causes Astigmatism?
Astigmatism can be present at birth (congenital) or develop over time due to eye injury, surgery, or certain diseases. The exact cause isn’t always known, but genetics often play a significant role. There are two main types: corneal astigmatism (due to an irregular cornea) and lenticular astigmatism (due to an irregular lens).
Common Symptoms of Astigmatism
If you have astigmatism, you may notice:
Blurry or fuzzy vision
Eyestrain or discomfort
Headaches
Difficulty seeing at night
Squinting to see clearly
These symptoms can vary depending on the severity and may worsen over time if left untreated.
How is Astigmatism Diagnosed?
A comprehensive eye exam conducted by an optometrist or ophthalmologist is essential for diagnosing astigmatism. Tests include a visual acuity test, keratometry, and corneal topography, which measure the curvature of the cornea and help determine the degree of astigmatism.
Treatment Options for Astigmatism
Astigmatism is highly treatable. The most common treatments include:
Prescription eyeglasses with cylindrical lenses
Toric contact lenses, specially designed for astigmatism
Refractive surgery, such as LASIK or PRK
