Astigmatism is a common refractive error of the eye that occurs when the cornea or lens is not perfectly spherical, causing light to bend differently in different directions. This results in blurred or distorted vision, both near and far.

Symptoms of astigmatism include headaches, eye strain, and difficulty seeing fine details, especially when reading or performing close-up tasks. It can occur on its own or in combination with other refractive errors, such as nearsightedness or farsightedness.

The most common treatment for astigmatism is corrective lenses, such as eyeglasses or contact lenses. These lenses work by bending the light entering the eye in such a way that it is focused correctly on the retina. Eyeglasses or contact lenses with a toric design are specifically designed to correct astigmatism.

In recent years, there have been advances in laser refractive surgery, such as LASIK and PRK, which can be used to correct astigmatism by reshaping the cornea. These procedures use a laser to remove small amounts of tissue from the cornea, which changes its shape and corrects the refractive error.

Another treatment option may include Orthokeratology (Ortho-K) which is a non-surgical method that uses custom-made contact lenses to reshape the cornea during sleep.

It is important for people with astigmatism to have regular eye exams to monitor the progression of their condition and to adjust their prescription as needed.

Overall, astigmatism is a common condition that can be effectively treated with corrective lenses, laser surgery, or possibly Ortho-K. With proper management, people with astigmatism can enjoy clear vision and good eye health.
