Astigmatism is a common vision condition that causes blurred or distorted vision at all distances. It occurs when the cornea (the clear front surface of the eye) or the lens inside the eye has an irregular shape — more like a football than a basketball. This irregular curvature causes light to focus on multiple points in the eye instead of a single clear point on the retina, leading to blurry or uneven vision.
– Irregular corneal shape: The most common cause.
– Lens irregularities: The lens inside the eye may also be unevenly curved.
– Genetics: Often present from birth and can run in families.
– Eye injury or surgery: May alter the curvature of the cornea.
– Blurry or distorted vision at all distances
– Eyestrain or headaches, especially after reading or computer work
– Difficulty seeing clearly at night
– Frequent squinting to focus
– Fluctuating vision clarity
Astigmatism is diagnosed during a comprehensive eye exam, which includes:
– Vision testing (refraction): Determines your prescription.
– Corneal topography or keratometry: Maps the shape and curvature of your cornea.
– Retinoscopy: Measures how light focuses in your eye.
The simplest correction. Special cylindrical lenses counteract the uneven curvature of the eye.
Toric lenses are designed specifically for astigmatism. Provide a wider field of vision and better cosmetic comfort. Rigid gas permeable (RGP) or hybrid lenses may be used for higher degrees of astigmatism.
Reshapes the cornea to correct irregular curvature. Suitable for many patients with mild to moderate astigmatism.
Used during cataract or lens replacement surgery to correct astigmatism. Provides clear vision without additional corrective lenses.
– Ensure regular eye exams to keep prescriptions accurate.
– Use good lighting when reading or working.
– Take frequent breaks from screens (the “20-20-20 rule”).
– Report any sudden changes in vision or eye comfort to your doctor.
Astigmatism is a very common and easily corrected vision condition. With the right prescription lenses or surgical options, patients can enjoy clear, comfortable vision at all distances. Regular eye checkups help ensure ongoing visual clarity and eye health.
