On completion of this subject, students should be familiar with the properties of ophthalmic optical materials and the indications for their use. Understand the optics of ophthalmic lenses and be able to calculate the performance characteristics of ophthalmic lenses and optical devices. Students will be able to dispense prescriptions and check dispensed visual aids to Australian standards. The subject will cover the properties of ophthalmic materials; the optics and design of bifocal and multifocal lenses relating to dispensed spectacle corrections; magnification effects, eikonic corrections and low vision aids; absorptive lenses; safety lenses; ophthalmic dispensing techniques; frame design, materials and adjustments; and dispensing tolerances, prescription verification and vertometry. The practical classes will introduce students to the processes of ophthalmic dispensing. Computer-aided learning will include a series of assignments that must be completed and submitted during the semester.

Computer-aided learning (CAL) and written assignments totalling 1000 words due throughout the semester (20%); a 100-minute practical examination in ophthalmic lenses and dispensing in the examination period (20%); a 2-hour written examination in the examination period (60%). Satisfactory completion of all three assessment components is necessary to pass the subject.
