Knowledge
• Con_30. Know the most relevant geometric, optical, and physical parameters that characterize all types of ophthalmic lenses used in optometric prescriptions and know how to relate them to the properties involved in the fitting process.
Skills and Abilities:
• HyD_1. Think in an integrated manner and approach problems from different perspectives with critical reasoning.
• HyD_2. Organize and plan work.
• HyD_3. Interpret results and identify consistent and inconsistent elements.
• HyD_4. Work as a team.
• HyD_5. Maintain an ethical commitment, as well as a commitment to equality and inclusion.
• HyD_8. Know how to analyze data and interpret experimental results specific to the fields of Optics and Optometry.
• HyD_12. Handle basic laboratory materials and techniques.
• HyD_17. Calculate the most relevant geometric, optical, and physical parameters that characterize all types of ophthalmic lenses used in optometric prescriptions and relate them to the properties involved in the fitting process.
Competencies:
• Comp_1. Students must have the ability to gather and interpret relevant data to make judgments that include reflection on relevant social, scientific, or ethical issues.
• Comp_3. Students must have developed the learning skills necessary to undertake further studies with a high degree of autonomy.
• Comp_4. Students must be able to apply the theoretical and practical knowledge acquired in the degree in a professional manner and be competent in posing/solving problems, as well as in developing/defending arguments in both academic and professional contexts related to Optics and Optometry.
• Comp_5. Ability to learn independently, work in a team, organize time and resources, and acquire new knowledge and techniques in Optics and Optometry.
• Comp_8. Ability to calculate the geometric parameters of specific visual compensation systems: low vision, intraocular lenses, contact lenses, and ophthalmic lenses.
Theoretical classes and seminars, with multimedia systems, to develop logically and consistently the teaching program of the subject, showing its relationship with other subjects of the degree.
Temporal distribution:
- 3 hours a week expositives, to teach the theoretical contents
- 1 biweekly hour of seminars
- 2 hours per week of practical classes in the technology workshop
GENERAL EVALUATION
The theoretical part and the practical part will be evaluated separately. The theoretical part will be assessed through a written exam, where errors in the answers may be penalized in the final grade, and the practical part through a practical exam at the end of the practical sessions. In addition there will be a continuous evaluation through the seminars.
In the final grade, 50% of the global grade will correspond to the theoretical part, 10% to the work in the seminars, and the remaining 40% to the practical part.
To be evaluated in the practical part, the student must attend a minimum of 6 sessions.
Those students who during the normal period of classes do not have attended the said minimum of 6s practical sessions will not be able to attend the July call.
To pass the course it is essential to obtain in each of the parts, theoretical and practical, at least a grade of 4 out of 10. And an overall grade of at least 5 out of 10.
EVALUATION WITH DISPENSE OF CLASS ATTENDANCE
It will be the same as in the general case, but without the requirement of attendance at the minimum of practical sessions
In cases of fraudulent performance of exercises or tests, the provisions of the"Normativa de avaliación do rendemento académico dos estudantes e de revisión de cualificacións" will apply.
It depends significantly in the working load and capacity of each student. So the following figures should be seen as a rough estimate:
Theoretical self-study: 50 h
Solving exercises: 16 h
Recommended readings, activities in library: 5 h
Other activities: 4 h
Overall work time: 75 h
1) Review of the knowledge acquired in Geometrical Optics.
2) To study, or at least have read the theory before the tutorials for each chapter.
3) Make use of the teachers office hours to consult and clarify doubts.
4) Do not memorize "recipes", but always understand what is being done.
