Which type of lens is used to correct astigmatism?

To correct astigmatism, a type of refractive error that causes blurred vision, special cylindrical lenses called toric lenses are used. Astigmatism occurs when the cornea or the lens of the eye has an irregular shape, causing light to focus on multiple points instead of a single point on the retina. Toric lenses have different powers in different meridians of the lens and are designed to compensate for the specific irregularities in the cornea or lens, allowing light to focus properly on the retina and providing clear vision. These lenses can be prescribed for eyeglasses or contact lenses, depending on the individual's preference and specific needs. It's important to consult with an eye care professional to determine the appropriate prescription and type of lens for correcting astigmatism.
