Can farsightedness and astigmatism be corrected with glasses?
Hyperopia is a condition where parallel rays of light entering the eye focus behind the retina, preventing external objects from forming a clear image on the retina. This condition is referred to as hyperopia. Astigmatism is due to the cornea of the eye having a certain curvature, with light bending unevenly across the cornea due to its irregular curvature, causing different refractive indices on each meridian of the cornea. This results in the light rays not focusing on the same focal point, thereby preventing the rays from accurately focusing on the retina to form a clear image. This condition is known as astigmatism. Both hyperopia and astigmatism are types of refractive errors, and wearing glasses can correct them. It is also necessary to wear glasses promptly for correction.
