This Standard replaces relevant text in AS 228.11992, which is intended to be withdrawn by February 2012. This Standard is identical with, and has been reproduced from ISO 8980-1:2004, Ophthalmic opticsUncut finished spectacle lensesPart 1: Specifications for single-vision and multifocal lenses single-vision and multifocal lenses and its Corrigendum, ISO 8980-1:2004/Cor.1:2006, which has been added after the source text. The objective of this Standard is to specify requirements for the optical and geometrical properties for uncut finished single-vision and multifocal spectacle lenses.

References to International Standards should be replaced by references to Australian or Australian/New Zealand Standards, as follows: Reference to International Standard ISO 13666 14889 Ophthalmic opticsSpectacle lensesVocabulary Ophthalmic opticsSpectacle lensesFundamental requirements for uncut finished lenses Australian/New Zealand Standard AS/NZS ISO 13666 Ophthalmic opticsSpectacle lensesVocabulary 14889 Ophthalmic opticsSpectacle lensesFundamental requirements for uncut finished lenses
Only international references that have been adopted as Australian or Australian/New Zealand Standards have been listed. The term informative has been used in this Standard to define the application of the annex to which it applies. An informative annex is only for information and guidance.

Scope
This part of ISO 8980 specifies requirements for the optical and geometrical properties for uncut finished single-vision and multifocal spectacle lenses.
Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 7944, Optics and optical instruments Reference wavelengths ISO 8429, Optics and optical instruments Ophthalmology Graduated dial scale ISO 8598, Optics and optical instruments Focimeters ISO 13666, Ophthalmic optics Spectacle lenses Vocabulary ISO 14889:2003, Ophthalmic optics Spectacle lenses Fundamental requirements for uncut finished lenses
For the purposes of this document, the terms and definitions given in ISO 13666 as well as the following apply. 3.1 focimeter, focal point on axis FOA focimeter focimeter in which the focal point of the focimeter remains on the axis of the focimeter when the lens under test is measured at a point of the lens where prism is not zero See Figure 1.
NOTE Examples of this design include all manual focusing focimeters and some automatic focimeters.
3.2 focimeter, infinite on axis IOA focimeter focimeter in which the collimated beam coincides with the focimeter axis and the focal point of the focimeter goes off the axis of the focimeter when the lens under test is measured at a point of the lens where prism is not zero
