Hyperopia is a phenomenon in which parallel light passes through the refractive system of the eye and is then refracted onto the retina, forming a diffuse ring of fog on the retina when the eye is relaxed. Hyperopia is usually categorized into refractive hyperopia and axial hyperopia. Refractive hyperopia is mainly caused by abnormal changes in the cornea and lens, and usually requires corrective treatment. Axial hyperopia is usually caused by the shorter eye axis, and the light and focus fall behind the retina. Axial hyperopia usually recovers with age as the eye axis grows. The prescription principle for hyperopia is to choose the lens with the best visual acuity and the highest prescription, e.g., if you can see 1.0 in both +3.00 D and +3.50 D, choose +3.5 D. If the hyperopia is mild and there is no vision loss or visual fatigue, you may not need to wear eyeglasses. If the farsightedness is combined with internal strabismus, choose the lens with the best visual acuity and the highest dioptre for full correction, which can relieve or eliminate the strabismus. If there is hyperopia with external strabismus, the best vision and lowest prescription glasses for hyperopia should be used. In adulthood, laser surgery is also an option under a doctor’s supervision. Patients with hyperopia can visit a hospital and choose the appropriate correction under the guidance of a doctor.
