What is Astigmatism?
Astigmatism is a common vision condition that affects millions of people worldwide. Despite its prevalence, it remains misunderstood by many.
Astigmatism Explained
Astigmatism is a refractive error that occurs when the cornea or lens of the eye is irregularly shaped. Instead of being perfectly round (like a basketball), the cornea or lens may have a slight oval shape. This irregularity causes light to focus unevenly on the retina, leading to blurred or distorted vision at any distance.
Common Symptoms
- Blurred or Distorted Vision: Objects may appear blurry or stretched out.
- Eyestrain: Difficulty focusing on objects for prolonged periods.
- Glare: Lights at night may look like starbursts.
Diagnosing Astigmatism
Diagnosis typically involves a comprehensive eye exam conducted by an optometrist or ophthalmologist. This may include a visual acuity test, refraction assessment, and measurement of corneal curvature.
