The majority of people with astigmatism are born with it, but in some cases, it can develop later in life. Astigmatism is caused when the cornea or lens is, or becomes, irregularly shaped. People with astigmatism can suffer from symptoms including blurred vision, headaches, eye irritation and even nausea. The good news is that astigmatism can be treated with refractive lens surgery, such as LASIK or corrective lenses. Therefore if youâ€ve been diagnosed and you want to correct the issue, gain a new lease of life and say goodbye to unpleasant symptoms, you should book a free consultation with Optegra.
