Yes, astigmatism can go back to normal, depending on the cause. Astigmatism is an eye condition in which the curvature of the cornea is irregular, making it difficult to focus on objects at a distance. The most common cause is genetics, but astigmatism can also be caused by injury, illness, or certain eye surgeries.
If the cause of the astigmatism is genetic, there is no known way to reverse it. The condition can be managed with the use of corrective lenses or contact lenses, but it cannot be reversed.
On the other hand, if the astigmatism is caused by an injury, illness, or surgery, it is possible that the condition may improve or even resolve completely. Depending on the cause, treatment may involve medications, surgery, or a combination of the two. In some cases, the cornea may be able to heal itself over time and the astigmatism can go back to normal.
It is important to see an eye doctor if you have any symptoms of astigmatism, or if you notice any changes in your vision. With regular eye exams and careful management of the condition, it is possible for astigmatism to go back to normal.
