Eye diseases are neglected by people in many cases. Today we will take a closer look at an eye disease called astigmatismfrom which a really large number of people suffer. What is it all about?

Astigmatism is a disorder of the eye that manifests itself curvature of the cornea or lens. A healthy eye is shaped like a ball, while people suffering from astigmatism have an eye shaped like a rugby ball. Basically, the point is that the optical system is differently curved and a blurred and blurry image is produced on the retina. In many cases it does not occur alone, but together with farsightedness or myopia. In ophthalmology we know two types of astigmatism:

  • regular astigmatism - resembles the shape of a rugby ball, the curvature is regular
  • irregular astigmatism - usually caused by injury, disease or degeneration, or scarring (the curvature is irregular)

Symptoms of astigmatism:

  • blurred or distorted vision
  • tired and strained eyes
  • headaches and migraines
  • discomfort in the eyes
  • people tend to close their eyes to see more clearly
  • squinting
  • problems with vision at night (when driving a car)

This disease is more noticeable especially when working with a computer for a long time and it also complicates the life of students who experience difficulties when reading books. However, it should be said that the above symptoms do not immediately indicate that you are suffering from astigmatism. Be sure to put yourself in the hands of an eye doctor to determine the real cause of your symptoms.

How can astigmatism be diagnosed?

The ophthalmologist will test the patient's visual acuity by asking them to read the letters on an eye chart. This will determine the clarity of vision at different distances. 


Phoropter is a device that helps figure out how to shape the lens to properly correct vision. The doctor tries several types of lenses on the patient to see which ones improve vision. Based on the patient's response, the doctor selects the lenses that provide the clearest vision.


The eye doctor may also use autorefractor to determine the corrective lenses the patient needs. The autorefractor has a light that shines into the eye and measures the changes on the eye as the light bounces off the back of the eye.


This is a device that measures the curve of the cornea of the eye. This allows the doctor to get more information about the shape and surface of the cornea. All three devices are designed to accurately diagnose and measure astigmatism.

How is astigmatism treated?

Most forms of astigmatism are perfectly fine to cure. Mild to moderate astigmatism can usually be corrected with contact lenses and glasses. These correct astigmatism by compensating for uneven curves in the cornea and lens. 

Another solution may be refractive surgery, which achieves a change in the shape of the cornea of the eye using laser surgery. Astigmatism can be operated on an outpatient basis and absolutely painless. If the cornea is irregularly curved, the doctor has to adjust it superficially - after this procedure the patient feels pain. 
The advantage of laser surgery is that relieves the patient of astigmatism permanentlyso you don't have to worry about wearing contacts or glasses. If you are considering this procedure, know that your eyes must be completely healthy - free of infections, injuries, corneal scars and other eye diseases.
