Astigmatism is a common condition characterized by an irregular curvature of the cornea or lens, leading to blurred or distorted vision at various distances. Unlike straightforward nearsightedness or farsightedness, astigmatism can affect your vision more complexly due to the eye's uneven surface. It can occur alongside other refractive errors and affects people of all ages.
Symptoms of Astigmatism
Common signs include:
- Blurred or distorted vision at all distances
- Eye strain, especially after reading or other prolonged visual tasks
- Headaches stemming from eye discomfort
- Difficulty with night vision
- The need to squint to see clearly
Causes and Diagnosis
Astigmatism may be hereditary or develop due to eye injury, disease, or surgery. It's diagnosed through a comprehensive eye examination, focusing on:
- Visual Acuity Test: To measure how well you can see at various distances.
- Refraction: This test determines the appropriate lens power needed to correct your vision by placing various lenses in front of your eyes.
Treatment Options
Astigmatism can be effectively managed with:
- Eyeglasses or Contact Lenses: Corrective lenses are often prescribed to counteract the distortion caused by astigmatism. Toric contact lenses, in particular, are designed to correct the uneven curvature of your eye.
- Laser Eye Surgery: For suitable candidates, procedures like LASIK or PRK can reshape the cornea, reducing or eliminating the need for corrective lenses.
