What Is Long Sightedness?

Long sightedness, also known as hypermetropia, is one of the most common eye conditions. In most people’s eyeballs, seeing objects at a distance any further than that of a small room requires focusing muscles to be totally relaxed and unstrained. However, for those people with hypermetropia, focusing muscles remain strained regardless of distance. It means that affected patients are challenged in their ability to see objects at a close distance.

And objects at a long distance can only be seen clearly if the level of long sightedness is low if the level is high and glasses are also needed for distance. In addition, presbyopic often develop sooner when one is longsighted.

As for long sightedness, light is focused behind the retina. This can lead to objects at a short distance appearing distorted or blurred.
