What is age-related long-sightedness, or presbyopia?
Presbyopia is part of the natural ageing process and involves a loss of the eye’s accommodative ability. From birth onwards, the crystalline lens gradually loses elasticity and therefore its capacity to focus clearly at different distances. As a result, the nearest point at which an object can be seen sharply moves progressively further away from the eye. However, the reduction in accommodative ability in emmetropic individuals usually only becomes noticeable between the ages of 40 and 50. One option for correcting presbyopia is the use of reading glasses, although the constant need to put them on and take them off can be inconvenient in everyday life. The ideal solution is progressive lenses, which provide clear vision from near to far.
