Langsýni

Langsýni is an Icelandic term that translates to "long sight" or "far-sightedness." It describes a condition where distant objects are seen clearly, but near objects appear blurred. This is a common refractive error of the eye, medically known as hyperopia. In langsýni, the eye's focal point is behind the retina, rather than directly on it. This can be due to the eyeball being too short or the cornea and lens not being curved enough to focus light properly on the retina.

The effects of langsýni can vary in severity. Mild cases might not cause noticeable vision problems, especially in younger individuals who have a strong ability to adjust their focus (accommodation). However, as people age and this accommodative ability diminishes, even mild hyperopia can lead to blurred vision at all distances, eye strain, headaches, and fatigue, particularly after reading or doing close-up work.

Langsýni is often present from birth, though it can sometimes develop later in life. It is diagnosed through a standard eye examination where an optometrist or ophthalmologist tests visual acuity and checks for refractive errors. Treatment typically involves corrective lenses, such as eyeglasses or contact lenses, which help to refocus light onto the retina, thereby correcting the blurred vision. In some cases, refractive surgery may also be an option for adults.
