Presbyopia

The resting eye forms the focal point behind the retina of the parallel light and is called hypermetropia (hyperopia). The optical focus of this eye is behind the retina, so the image formed on the retina is blurred. In order to see distant objects clearly, the focus behind the retina must be moved to the retina using the adjustment power. Therefore, hyperopia eyes are often in an adjusted state and prone to eye fatigue.
