People with presbyopia can make use of a new type of contact lens produced by CIBA Vision.

Air Optics Aqua Multifocal lenses are intended to target people over 40, who often stop using contact lenses.
An age-related condition, presbyopia causes people to have difficulty in seeing objects that are near to their eyes and may have to hold things away in order to read them.
It is thought to be caused by the lens inside the eye becoming more rigid as part of the ageing process.
Usually, the symptoms are first noticed between the ages of 40 and 50.
