Astigmatism is an eye condition that results in blurred vision due to the inability to focus a singular object. Astigmatism, which may affect only one eye is typically caused by an irregular (toric) shaping of the eye’s cornea or lens, which subsequently distorts natural vision. According to studies, nearly 30% of all children worldwide have astigmatism, and a little over 30% of all adults also have astigmatism, most of which is relatively mild.

Types of Astigmatism

  • Irregular astigmatism is usually caused by a scarring or scattering of the lens, and can only be corrected with contact lenses.
  • Regular astigmatism is more common, and results from a mis-shaping of the circular shape of the lens and cornea into a toric shape. Regular astigmatism can be fixed with toric eyeglasses or contact lenses.

Astigmatism Symptoms and Treatment

The most common signs one has astigmatism are blurred vision, headaches, and frequent squinting. Minor astigmatism is common, and many are unaware that they have astigmatism due to the lack of symptoms. For people who have more prevalent astigmatism, there are a few treatment options.

The most common treatment for astigmatism is to wear eyeglasses or contact lenses. Toric lenses can be designed to counteract the distortion in the eye, although not all people prefer to wear contact lenses or eyeglasses. Some may choose to undergo procedures such as Lasik surgery to treat astigmatism  as well as any other eye problems they may be experiencing. A new technique known as Mini Asymmetric Radial Keratotomy also has been developed to permanently treat Astigmatism symptoms.
