text: In presbyopia, which is due to loss of elasticity of the lens with age, it is the amplitude of accommodation that is reduced-that is, the distance between the far and near points; the latter (from about 10 cm at the age of 10 years) moves further away the older one gets; the correction is made by means of unifocal or multifocal convergent lenses; the latter correct for ever nearer distances of the object (usually up to 30 cm) by taking into account that nearer objects are generally perceived in the lower part of the visual field, while the upper part of the spectacles is reserved for distance vision.
