Presbyopia (sometimes called middle age vision) is the gradual loss in the ability of the eye to focus on near objects. This change occurs over many years.
By our early to mid-forties the lens in our eye starts to harden and lose its flexibility. This is a natural part of the aging process but means it becomes increasingly difficult to focus on close objects.
Presbyopia can be corrected using reading spectacles, multifocal spectacles or, in some cases, multifocal contact lenses. Good lighting when doing near tasks is also important to optimise visual performance and comfort.
