The International Organization for Standardization (ISO) has published the latest global standard for contact lenses, pertaining to the sale and use of the products.
In ISO 14534:2011, Ophthalmic Optics - Contact Lenses and Contact Lens Care Products – Fundamental Requirements, the organisation has created standards which will apply across many different countries and help to eliminate confusion.
The standard, which is the third edition issued by the ISO, specifies safety and performance requirements for contact lenses and related products, including the need for frequent and stringent risk assessments.
It also contains specifications for design, materials, clinical evaluation and manufacturing, as well as microbiological requirements and issues pertaining to packaging such as shelf-life, discard dates and labelling.
Recent data compiled by the Association of Contact Lens Manufacturers and seen by Optician Online showed that the British contact lens market expanded by seven per cent last year, compared with 2009, and now stands at a total of £219.5 million.
