Astigmatism: A Bird’s Eye View
Astigmatism is a refractive error—meaning the manner in which light waves curve as they traverse the lens and cornea.—caused by a malformation the translucent layer that protects the iris, pupil, and lens. For example, a normal cornea is perfectly round, like a baseball, while an astigmatic cornea has a spherical or oval shape. Due to this malformation, the eye cannot properly focus which is why people who suffer from astigmatism experience distorted, blurred vision.
Oftentimes, astigmatism is a hereditary condition and comorbid with additional refractive disorders such as near or farsightedness. Injury to the eye as well as surgical procedures can also result in astigmatism. Either way, as we age, the symptoms of this disorder tend to intensify.
If you’ve been diagnosed with astigmatism, there are a number of options available to correct the problem and restore clear vision.
- Eyeglasses (the most common solution)
- Contact lenses
- Orthokeratology (gas permeable contact lenses worn overnight)
- Laser surgery
