GSO ISO 9342-2:2007 Scope
This part of ISO 9342 specifies requirements for test lenses for focimeters that are used to measure contact
lenses. These test lenses are used to find the precise correction values that are needed to convert the power
values measured to back vertex power values, as defined in Clause 3.
This part of ISO 9342 applies to focimeters meeting the requirements of ISO 8598.
