Presbyopia occurs between the ages of 40 and 50. It refers to the ageing process of the eye, and literally translates as ‘old eye’. In a younger eye, the crystalline lens changes shape to allow us to focus on objects at different distances. As we get older, the lens begins to lose this elasticity, so it becomes more difficult to see things close up – for instance, we may find the need to hold things further away from us to read them. This is presbyopia.
There are a number of solutions to help patients with presbyopia, such as reading spectacles, bifocal lenses and varifocal lenses. Multifocal contact lenses are also available for presbyopes, so those who do not wish to wear spectacles can still enjoy clear vision.
