What is astigmatism?


 
Astigmatism is a common refractive error that affects the shape of the eye's cornea or lens. In a normal eye, the cornea and lens are smooth and evenly curved, helping to focus light rays directly onto the retina at the back of the eye. However, in eyes with astigmatism, the cornea or lens has an irregular shape, causing light to focus unevenly on the retina. This results in blurred or distorted vision at various distances.

 

What causes astigmatism?


Astigmatism can be present from birth, and some individuals are born with this refractive error.

It may also develop later in life due to various factors such as development changes in early years of life, genetic factors increase the likelihood of getting astigmatism, environmental factors such as eye injuries or surgeries or age-related changes that lead to the onset or progression of astigmatism in later life.
 

Astigmatism symptoms

 
Common symptoms of astigmatism include:

 
  •   Blurred or distorted vision at all distances
  •   Eye strain and discomfort
  •   Headaches
  •   Squinting to see clearly
  •   Difficulty with night vision

Treatment for astigmatism  

 
Whether present from birth or acquired later on, astigmatism is a common refractive error that can be easily corrected with eyeglasses or contact lenses. In some cases, refractive surgery may be considered as a more permanent solution.

Regular eye examinations with an optometrist or ophthalmologist are essential to detect and address astigmatism, especially since visual needs can change over time. If you suspect you have astigmatism or are experiencing changes in your vision, it's recommended to consult with your trusted Spec-Savers optometrist for a comprehensive eye examination.
