Course Description

This unit describes the skills and knowledge required to evaluate client needs, take measurements and make calculations to facilitate effective dispensing for atypical prescriptions, including for low vision clients. Low vision occurs when, after accurate refraction and the provision of spectacles or contact lenses to correct the refractive error, good visual acuity is not achievable.

Details of Learning Activities

A combination of activities will support students learning in this course, such as:
• Face to face and or online lectures to cover theoretical and practical concepts for each topic in the course
• Students will learn to apply their skills and knowledge to work integrated learning (WIL), during simulations and classroom based learning
• Observations of performance in the workplace and industry placement or simulated environment will be a valuable part of your learning experience
• Tutorial activities (individually and in teams) to discuss, debate, critique and consolidate your ideas and extend your understanding around key concepts within specific topics
