In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
The skills, values and knowledge reflected in this unit standard are required by people who have to solve technical optical problems in a manufacturing and/or assembly process. Learners who achieve this unit standard will demonstrate a fundamental knowledge base of optical manufacturing and contribute to the optical sector in manufacturing lenses and optical appliances by cleaning and inspecting optical lenses.

A person credited with this unit standard is able to:
  • Prepare the lens to be fitted into spectacle frame.
  • Fit lens in accordance with shape, mounting of frame.
  • Apply the appropriate quality assurance measures.

    The achievement of this unit standard contributes to the exit level outcomes required for the National Certificate in Optical Manufacturing Processes and related qualification. It further contributes to the professional development of learners within the optical manufacturing environment and provides further mobility and transportability within the field of Manufacturing, Engineering and Technology. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
