Astigmatism is a type of refractive error, and taking lutein in this case will not help, neither will it reduce the astigmatism nor improve the vision. Astigmatism is usually caused by an uneven curvature of the cornea or an irregular shape of the cornea, so it can lead to vision loss or eye fatigue. Treatment for astigmatism is still focused on correcting vision. For mild astigmatism, treatment is usually not needed because it does not cause vision loss. For moderate to high astigmatism, such as astigmatism of more than 200 degrees, it will definitely cause vision loss of different degrees, and it is also easy to have eye fatigue symptoms in general, so you need to improve your vision through frame glasses or corneal contact lenses, and adults can also choose keratoconus surgery to improve vision.
