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
• Online discussion and activities support you to collaborate with other students in your course and debate and debate and discuss ideas
• Self directed study time to enhance and strengthen your knowledge and understanding of theoretical concepts
• To further facilitate learning, students are strongly encouraged to use a range of communication tools between themselves and their course instructor as well as between themselves and fellow students by using the online learning platform

All students will be contacted with 7 days by their course coordinator in regards to resubmission completion dates.
Please note an opportunity to repeat placement (Full time students ONLY)is not guaranteed and will be at the discretion of the Program Coordinator/Program Manager.
EXTENSION OR SPECIAL CONSIDERATION
If due to illness or other unforeseen circumstance, you are unable to attend on the due date of an assessment (e.g. test, examination, oral, etc.) OR you do attend, but your
