Long-sightedness

As with short-sightedness, a displacement of the eye’s focal point also occurs with long-sightedness. Longsighted eyes are often shorter than eyes with normal vision. As a result, the refractive power of the eye is too low and the incident rays of light are not bundled until they are behind the retina. The shorter the eye, the greater the long-sightedness and the associated blurriness.

With this form of defective vision, some patients still see objects at a distance fairly well, but objects that are closer appear blurry.

In young people, long-sightedness can be compensated for by changing the shape and, hence, the refractive power of the lens (accommodation). However, this capability is lost with advancing age ( Presbyopia).

To allow sharper vision, laser surgery such as LASIK (up to +3 dpt) and lens surgery such as ICL (up to +10 dpt) or RLE (from +10 dpt) are used.
