Astigmatism is a common vision problem that causes blurred vision due to an irregularly shaped cornea or lens in the eye. It affects how light travels through the eye, resulting in objects appearing blurry or distorted. The amount of astigmatism correctable with glasses depends on the severity of the condition and the prescription strength of the glasses.
Mild astigmatism, which is a condition where the cornea or lens is slightly curved, can usually be corrected with glasses that have a lower prescription strength. For moderate astigmatism, which is a condition where the cornea or lens is more curved, glasses with a higher prescription strength may be needed. In addition, glasses with a special cylinder lens may be necessary to correct more severe astigmatism.
Ultimately, the amount of astigmatism that can be corrected with glasses depends on the individual’s eye condition and prescription strength. However, it is possible to correct most cases of astigmatism with glasses. In some cases, contact lenses may also be used to correct astigmatism.
