When the eye is relaxed, parallel light from a distance enters the eye, passes through the refractive system, and instead of being imaged on the retina, it is eventually imaged behind the retina; such a refractive state is called hyperopia. In patients with mild hyperopia, there may be no significant change in distance vision because of the presence of accommodation. In the case of moderate to high hyperopia, there will be a decrease in distance vision, which will also affect near vision if one is older and has insufficient accommodation. For hyperopia, it is still generally corrected by frame glasses or corneal contact lenses. If the farsightedness is mild, frame glasses can be used, but if the degree is high, contact lenses can be considered for correction. Refractive surgery can also be considered for farsightedness correction at this time. Excimer laser refractive surgery, for example, uses a laser to cut no tissue in the central region, but only the peripheral tissue, so that the peripheral part becomes flat and the central cornea becomes convex, and the central corneal refractive power can be increased, thus achieving the purpose of correction. Generally, the effect of farsightedness correction within 600 degrees is better. Intraocular refractive surgery, such as refractive lens replacement or IOL implantation, can also be done. Farsightedness is a loss of vision when looking at distance and near. Treat it as early as possible.
