Far-sightedness, also known as long-sightedness and hyperopia, is a condition of the eye in which light is focused behind, instead of on, the retina. This causes close objects to be blurry, while far objects may appear normal. As the condition worsens, objects at all distances may be blurred.
What Is Farsightedness? Farsightedness means itâs easy to see things that are far away, but your close-up vision (near vision) is blurry. The technical term for farsightedness is hyperopia. According to the National Eye Institute, it affects 5 to 10 percent of Americans. To understand farsightedness, itâs important to understand how the eye works. Two parts of the eye are responsible for focusing: the cornea and the lens.
