655-359 Ophthalmic Lenses and Optical Dispensing

This subject is only available to students who previously attempted the subject in 2006.

One of Optometry 655-210 or 655-219 or 655-311.

This subject will apply the optics knowledge and skills obtained in the prerequisite subjects to the design, prescription and dispensing of ophthalmic lenses. On completion of this subject, students will have a detailed understanding of the optics of ophthalmic lenses. In addition, students will be familiar with the properties of ophthalmic optical materials and the indications for their use. Students will have the skills to dispense prescriptions and check dispensed visual aids for compliance with the Australian standards. The subject will cover the properties of ophthalmic materials; the optics and design of bifocal and multifocal lenses; anisometropia, 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.

This subject offers students the opportunity to integrate their existing knowledge and analytical skills to tackle new and unfamiliar problems in optics. Opportunities will be provided for students to work with others during practical classes, but they will need to manage their own time effectively in order to complete their ongoing assessment tasks and prepare for end of semester examinations. The series of practical calculation assignments to be completed will require critical thinking and organisation of material delivered in lectures and from web resources. Students will hone important time-management skills in order to manage their study time effectively and ensure they keep up to date with the subject material.

Computer-aided learning (CAL) and written assignments totalling 1000 words due during the semester (15%); a 100-minute practical examination in the examination period (15%); a 3-hour written examination in the examination period (70%). Satisfactory completion of all three assessment components is necessary to pass the subject.
