ASTIGMATISM

astigmatism

Astigmatism is a common vision problem caused by an error in the cornea. It is a type of refractive error caused when either your cornea or lens has mismatched curves.

This causes blurry, fuzzy, or distorted vision. 

Types:

There are two main types; corneal and lenticular. Corneal astigmatism occurs when your cornea has mismatched curves. Lenticular astigmatism is a result of a difference in curvature in the lens.

What causes Astigmatism?

There is no known cause, but genetics is a significant factor. It is often present at birth, but it may develop later in life.

It may also occur as a result of an injury to the eye or after eye surgery. Also, this disease often occurs with nearsightedness or farsightedness. 

Astigmatism is a disease that affects both children and adults. However, the risk of developing it may be higher if you have any of the following: 

  • A family history of astigmatism or other eye disorder such as Keratoconus
  • Scarring or thinning of your cornea
  • Excessive nearsightedness creates blurry at a distance
  • Extreme farsightedness makes blurry close-up vision
  • A history of certain types of eye surgery such as Cataract surgery

Symptoms:

The symptoms of astigmatism may differ in each person. Some people might not show any symptoms at all. These symptoms include: 

  • Blurry, distorted, or fuzzy vision at all distances( up, close and far away)
  • Difficulty seeing at night
  • Eyestrain
  • Squinting
  • Eye irritation
  • Headaches

 See a doctor if you notice any symptoms. Some signs may also be due to other health or vision problems.
