Splet24. jun. 2024 · The medical name for long-sightedness is hypermetropia, sometimes called hyperopia. Eyesight problems, such as hypermetropia, are also known as refractive errors. Long-sightedness leads to problems with near vision (seeing things that are close up) and the eyes may commonly become tired. Distance vision (long sight) is, in the beginning, … SpletIn a myopic eye, the image of a distant object is formed in front of the retina and not at the retina itself. ii) Hypermetropia is also known as farsightedness. A person with hypermetropia can see distant objects clearly but cannot see nearby objects distinctly.

Near-sightedness, also known as myopia and short-sightedness, is an eye disease [5] where light focuses in front of, instead of on, the retina. [1] [2] As a result, distant objects appear blurry while close objects appear normal. [1] Other symptoms may include headaches and eye strain. [1] SpletIn order to correct vision in a short sighted patient, the light rays need to be redirected so that they focus in the right place. This can be done in several ways, including: Glasses or contact lenses.
