What are the causes of astigmatism and how can we cure it?

Astigmatism is a condition where the cornea has an irregular shape that causes problems with vision. The cornea, the clear covering of the lens and iris, serves as a protection to the eye and helps transmit light through the eye. The cornea is normally spherical in shape, but those with astigmatism may have their cornea more oval shaped. This oval shaping causes light to scatter instead of focusing to a single point as it passes through the cornea and results in blurred vision.
LASIK Surgery for Astigmatism
A common misconception is that LASIK eye surgery doesn't apply to astigmatism, but that's false.
LASIK eye surgery is by far the most commonly selected procedure for refractive eye surgery. During the LASIK procedure, a small incision creates a corneal flap and an excimer laser is used to reshape the cornea. The excimer laser is different from other lasers in that it doesn't produce heat. Once the procedure has been completed, the corneal flap is repositioned normally and the healing process begins. Most people can notice quite an improvement in vision immediately upon completion of the procedure.

cant cure it but you can treat it, its caused by genetics . Both glasses and contacts all those help but they have to be special made. I have astigmatism, if your like me and its only to a small degree you can wear regular contacts and glasses and wont affect vision much. But if the astigmatism is of a higher degree you will need special made contacts and i think acuvue makes a mass produced one called acuvue with astigmatism.
