Overview
Ophthalmic Optics is a fundamental area of Vision Science and Optometry, as a majority of problems deal with in these fields require optical solutions. It provides much of the optical basis for other units in the Optometry and Vision Science course dealing with optics, and thus is placed early in the course.
Learning Outcomes
On successful completion of this unit you will be able to:
- Describe the basic principles of geometrical optics as they pertain to vision science and optometry;
- Recognise and solve problems relating to the optics and design of ophthalmic lenses which may arise in clinical practice;
- Describe ophthalmic lens types and materials that are available for the correction of vision disorders.
Content
The unit addresses the following at an introductory level: lens form and thickness and correction of refractive errors; optical treatment of contact lenses; spectacle lens design; refraction and notation of spherical and astigmatic lenses, including lens neutralisation and transposition; prismatic effects of ophthalmic prisms and lenses; bifocal and multifocal lenses, including optical and mechanical requirements, segment terminology, and prismatic effects; frame and lens materials and dimensions, including assessment of lens quality; lens thickness calculations; vertometers; refractive errors and special lens types
You will also be introduced to problem solving processes and critical thinking in the context of optics and lens designs; principles of laboratory ordering and prescription writing, and ocular protection against radiation and mechanical hazards.
OPB353 builds on learning from PCB150 Biomedical Physics and MAB141 Mathematics and Statistics for Health Professions in first year, and is taught concurrently with the complementary unit PCB240 Optics. OPB353 supports the later study of the optics of the eye, refractive errors and accommodation in OPB351 Visual Science 3 in Semester 2 of Year 2, and underpins the further development of the ophthalmic optics of spectacle corrections in OPB453 in second semester.
Relates to learning outcomes
Graduate capabilites addressed in this unit include:
1. Knowledge and skills pertinent to vision science and the practice of optometry;
2. Critical, creative and analytical thinking, and effective problem-solving.
Learning Approaches
This unit will involve three hours of lectures/tutorials and a two hour practical/demonstration class each week. Your learning is also supported by a website that provides a range of study materials and activities.
Together with OPB453 Ophthalmic Optics 4, the two ophthalmic optics units contribute to the development of graduate skills relevant to the Optometry entry-level competency standard elements 4.5 Prescribes spectacles and 4.6 Dispenses spectacle prescriptions accurately and the performance criteria within these elements (Kiely and Slater 2015).
Feedback on Learning and Assessment
Formative Assessment:
The unit co-ordinator will be available in person and via e-mail to discuss issues and answer questions, particularly regarding problem exercises and performance in the mid-semester examination. Feedback on development of practical and technical skills is provided through the practical sessions, and learning support materials on Canvas guide students as to their understanding.
Assessment
Overview
There are 3 pieces of summative assessment in this unit.
Satisfactory performance in each of the assessment items is a condition for passing this unit. This means that at least 50% must be obtained on the end of semester examination for a passing grade to be awarded. The Faculty of Health Threshold Assessment Policy will apply where student performance in an assessment item is unsatisfactory.
Unit Grading Scheme
7- point scale
Assessment Tasks
Assessment: Laboratory/Practical
This will involve demonstration of practical skills in solving optical problems and by making optical and mechanical measurements with spectacles, such as lens power, surface power, PD's, segment heights and frame dimensions.
Threshold Assessment:
Satisfactory performance in each of the assessment items is a condition for passing this unit. This means that at least 50% must be obtained on the end of semester examination for a passing grade to be awarded. The Faculty Threshold Assessment Policy will apply where student performance in an assessment item is unsatisfactory.
Assessment: Mid-semester practical slide assessment
Evaluation of competency to describe and interpret optical characteristics related to ophthalmic optics.
Threshold Assessment:
Satisfactory performance in each of the assessment items is a condition for passing this unit. This means that at least 50% must be obtained on the end of semester examination for a passing grade to be awarded. The Faculty Threshold Assessment Policy will apply where student performance in an assessment item is unsatisfactory.
Assessment: Examination (theory)
End-of-semester theory examination. This will include a range of questions related to knowledge, analysis and solving problems in optics.
Threshold Assessment:
Satisfactory performance in each of the assessment items is a condition for passing this unit. This means that at least 50% must be obtained on the end of semester examination for a passing grade to be awarded. The Faculty Threshold Assessment Policy will apply where student performance in an assessment item is unsatisfactory.
Academic Integrity
Students are expected to engage in learning and assessment at QUT with honesty, transparency and fairness. Maintaining academic integrity means upholding these principles and demonstrating valuable professional capabilities based on ethical foundations.
Failure to maintain academic integrity can take many forms. It includes cheating in examinations, plagiarism, self-plagiarism, collusion, and submitting an assessment item completed by another person (e.g. contract cheating). It can also include providing your assessment to another entity, such as to a person or website.
You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.
Further details of QUT’s approach to academic integrity are outlined in the Academic integrity policy and the Student Code of Conduct. Breaching QUT’s Academic integrity policy is regarded as student misconduct and can lead to the imposition of penalties ranging from a grade reduction to exclusion from QUT.
