Advanced Lens Cosmesis; Blending Optical Theory with Cosmetic Lens Design
Designing the most optically precise and cosmetically appealing lenses shouldn’t be left to common myths and optical roulette. This course explores the art and science of modern ophthalmic lens design. Topics include ophthalmic substrates, advanced geometric design, sagittal aspheric, tangential atoric, micro prism balancing, refractive index delta, lens thickness, advancements in thin film, low to higher order aberration mitigation and frame considerations.
Learning Outcomes
Upon completion of the course, students should be able to:
- Explain the key factors and considerations of precision lens design and cosmesis.
- Describe the expected outcomes of varying designs such as spherical, aspheric, atoric, substrate delta, lens thickness, and reflectance factor on the performance and appearance of ophthalmic lenses.
- Apply theoretical concepts to real-world scenarios, demonstrating the ability to design and recommend appropriate lens options based on individual needs and preferences.
