For most people, the eyeball takes a perfectly spherical shape. This helps light refract properly to offer you a clear line of sight. When your eyes deviate too far from the round shape, it is unable to bend light correctly and can cause vision errors. This makes it difficult to focus on objects, leaving them with a blurry appearance. This condition is referred to as Astigmatism.
Causes
Astigmatism is normally present from the time of birth. However there are cases where the condition develops after sustaining trauma or injury to the eyes, as an unwanted side effect of eye conditions or diseases or due to surgery.

It is also common to find astigmatism coupled with other refractive errors i.e. myopia and hyperopia. Under rare circumstances, a vision condition called Keratoconus, could trigger Astigmatism.
Symptoms and Diagnosis – If you are suddenly facing the following symptoms, head to your eye care professional for an eye examination.
- Blurry vision or distortion
- Strain in the eyes
- Strong headaches
- Trouble with night vision

The symptoms tend to develop slowly, but regular visits to your eye doctor ensures adequate testing for a faster diagnosis and solution.
Treatment
If you have been diagnosed with Astigmatism, there are three possible correctional treatments you can undertake:
Corrective Contact Lenses – Contact lenses work like eyeglasses to correct astigmatism. Contact lenses are also used in orthokeratology. This is a process used to correct the shape of the cornea by wearing rigid lenses while you sleep. However discontinuing this treatment will return the eye to its previous shape along with the refractive error.
Corrective Eyeglasses – The lenses of corrective eyeglasses help makeup for the uneven shape of the eye. They also help correct other refractive errors.

Refractive Surgery – Refractive surgery uses a laser to reshape the cornea, correcting the refractive error. You will no longer require external apparatus like glasses for clear vision. Consult a doctor before making the decision.
It is important to note that astigmatism cannot be caused by sitting in dim lighting for too long or watching the television too close.
