Learning outcomes In this UC is intended that students learn and apply the fundamental principles of ophthalmic optics including the various steps associated with the selection, prescription and fitting of ophthalmic lenses as a traditional way to compensate refractive errors. At the end of this course unit student should be able to: Measure the geometrical parameters associated with ophthalmic lenses; Identify the types of materials and treatment of lenses and frames; Identify spherical, astigmatic, aspheric, toric and multifocal lenses; Understand the power resulting from oblique cross cylinder; Calculate the prismatic effects induced by decentralization; Describe the effects of ophthalmic lenses on the visual field, accommodation and image size; Measure the power of spherical, astigmatic monofocal lenses and multifocal lenses; Analyze and interpret prescriptions for ophthalmic lenses; Mounting ophthalmic lenses in frames according to the parameters of ophthalmic prescription.

Planned learning activities and teaching methods To fulfill the tasks defined for this course unit are scheduled theoretical-practical classes where, through the exposure of subject and solving exercises, the student has the opportunity to develop and consolidate their knowledge. Are also planned laboratory classes where students have the opportunity to apply the knowledge acquired by carrying out practical procedures related to the field of ophthalmic optics.
Metodologias de Ensino e Critérios de Avaliação Para obtenção de frequência, cada estudante deverá:
- frequentar assiduamente as aulas práticas da disciplina (sendo-lhe permitida apenas uma falta não justificada), obtendo a classificação P, através da realização obrigatória de dois testes práticos e da avaliação contínua de desempenho no laboratório;
- ter um número mínimo de presenças em aulas teorico-práticas igual a metade das aulas leccionadas;
- efectuar um teste teórico (T) [03.01.2019 - 14:00, sala 07/02];
- obter aproveitamento na componente laboratorial, P >= 9,5 valores;
- obter classificação superior a 6,0 valores na classificação de ensino-aprendizagem (CEA), obtida atraves da expressão:
CEA = 1/2T + 1/2P.

O aluno será dispensado de exame se T >= 9,5 valores e P >= 9,5 valores.

A aprovação por exame será obtida se o aluno obtiver classificação final (CF) igual ou superior a 9,5 valores, sendo CF obtida a partir da expressão:
CF = 1/2E + 1/2P,
onde E = teste de exame.

Os estudantes com regime de trabalhador estudante ficam libertos da presença às aulas e poderão optar por um regime alternativo para obtenção da componente prática, P, funcionando a CEA e a CF da mesma maneira que para os restantes estudantes. Este regime consiste na elaboração de um trabalho, orientado pelo docente, e para usufruir dele o aluno deve inscrever-se até à segunda semana de aulas. Data limite para entrega do trabalho: dia de realização do teste teórico.
Language Portuguese. Tutorial support is available in English.
