The global contact lens market is estimated at USD 6.1 billion and is constantly on the rise. There are different types of contact lenses; soft contact lenses, disposable daily-wear contact lenses, rigid contact lenses, etc., offering more and more comfort and convenience in their daily use.
The revised ISO standard, ISO 11987:2012, Ophthalmic optics – Contact lenses – Determination of shelf-life, will enable manufacturers to recommend storage conditions throughout the time of their storage and distribution.
The standard specifies test procedures to be applied to lenses, to measure whether the lenses have changed their properties from the time of their manufacture, once they are placed in their final packaging, up until the time they are first used by the wearer.
ISO 11987:2012 was developed by ISO technical committee ISO/TC 172, Optics and photonics, subcommittee SC 7, Ophthalmic optics and instruments. It is available from ISO national member institutes (see the complete list with contact details). It may also be obtained directly from the ISO Central Secretariat, price 50 Swiss francs through the ISO Store or by contacting the Marketing, Communication & Information department.
