In opposition to short-sightedness stands far-sightedness – also referred to as “hyperopia”. With this defective vision, objects that are close by, cannot be seen clearly. In analogy to myopia, hyperopia can be explained by a too short eyeball. The farsighted eye is too short in relation to the refractive power. The focal point here is located behind the retina, which means that the refractive power is proportionally too weak.
Through the lens of the eye, we have the ability to adjust our focus by increasing its convexity. This acts in a similar way to the camera’s mechanism, which can focus on near and far objects. This adjustment is known as “accommodation”.
