Dispense optical appliances


Application

This unit describes the skills and knowledge required to use specialised optical knowledge to confirm and check appliance selection, fit appliances and follow procedures to complete the dispensing process.

This unit applies to optical dispensers who work according to prescriptions provided by optometrists or ophthalmologists.

The skills in this unit must be applied in accordance with Commonwealth and State/Territory legislation, Australian/New Zealand standards and industry codes of practice.
