Astigmatism is a common refractive error caused by an irregularly shaped cornea or lens, leading to blurred or distorted vision at all distances. Symptoms include eye strain, headaches, and difficulty seeing at night. It can be diagnosed through a comprehensive eye exam and corrected with glasses, contact lenses, or refractive surgery.
Astigmatism occurs when the cornea or lens has an irregular shape, preventing light from focusing properly on the retina. Common causes include genetics, eye injuries, keratoconus, and prior eye surgeries. Some cases develop naturally over time or due to excessive eye strain. Symptoms include blurred or distorted vision at all distances.
Astigmatism symptoms include blurry or distorted vision at all distances, eye strain, headaches, and difficulty seeing at night. Squinting to see clearly is common, along with frequent changes in eyeglass or contact lens prescriptions. Symptoms may worsen with prolonged screen use or reading. An eye exam is necessary for diagnosis and treatment.
Astigmatism distorts vision due to an irregularly shaped cornea or lens, preventing light from focusing properly on the retina. This leads to blurry or stretched images at all distances, along with eye strain, headaches, and difficulty seeing at night. Common symptoms include squinting and halos around lights. It can be present from birth or develop over time.
Astigmatism treatment options include eyeglasses, contact lenses, and refractive surgery. Toric lenses in glasses or contacts help correct uneven corneal curvature, improving vision. Laser procedures like LASIK or PRK reshape the cornea for long-term correction. In severe cases, specialized implants or corneal transplants may be needed. Treatment choice depends on severity and patient needs.
