Detailed Solution

Concept: Other names for hypermetropia include hyperopia, long-sightedness, and far-sightedness. The eye disease known as hypermetropia is characterized by the formation of an image of a close object behind the retina. Instead of concentrating on the retina in this instance, the light is concentrated behind the retina.
As seen in the photograph, the light rays emanating from the object that is put close to the eye are gathering behind the retina instead of at the retina. Because of this, the image of an item that is put close to the eye cannot form properly at the retina but instead appears hazy. Farsightedness is the inability to produce a distinct image of an item that is put close to the eye, and hypermetropia is the medical term for this eye problem.
