What about farsightedness?

Hyperopia is a common disease in ophthalmology, belonging to a type of refractive error. It is caused by congenital abnormalities that the corneal curvature is too flat, or the refractive power of the cornea is too weak, and the anterior and posterior diameters of the eyeball are too short. Therefore, after the light reflected by external objects is refracted by the refractive system of the eye, the focus formed by convergence cannot be accurately focused on the retinal screen, but focused on the rear of the retina, causing the projection on the retina to become blurred. Therefore, it causes vision decline and blurred vision. Hyperopia patients need to go to the ophthalmology department of the hospital for medical optometry to determine the accurate degree. Hyperopia within 100 degrees has little effect on vision, and it is not easy to cause symptoms of visual fatigue, so special treatment is not necessary. Hyperopia above 100 degrees will affect the quality of vision, and glasses should be worn for correction.
