Advanced Ophthalmic Lenses and Dispensing II is an in-depth course that builds upon the foundational knowledge gained in the introductory level course. This advanced course focuses on intricate aspects of ophthalmic lenses and dispensing, equipping students with specialized skills and expertise necessary for professional practice in optometry, ophthalmology, or opticianry.
The course curriculum is structured around key topics essential for mastering advanced lens technologies and dispensing techniques. Students will delve into the following areas:
Frame Measurements and Markings: Understanding the significance of accurate frame measurements and markings in ensuring proper lens alignment and fit. Practical exercises will cover techniques for measuring pupillary distance, frame dimensions, and other critical parameters essential for precise lens positioning.
Lens De-Centration and Prisms: Monocular: Exploring the principles of lens de-centration and prism correction for monocular vision disorders. Students will learn to calculate and apply prism corrections effectively to address visual distortions caused by eye misalignment, enabling optimal visual clarity and comfort for patients.
Lens De-Centration: Bifocal Lenses: Analyzing the complexities of lens de-centration specific to bifocal lenses. Practical demonstrations will illustrate techniques for determining the appropriate placement of bifocal segments based on patient prescription and visual needs, ensuring seamless transition between near and distance vision.
Progressive Lenses Verification and Edging: Mastering the verification and edging processes for progressive addition lenses (PALs), including techniques for assessing lens parameters such as corridor width, near and intermediate zones, and lens power distribution. Hands-on practice will enable students to verify and edge progressive lenses accurately, maintaining optical precision and visual comfort.
Blocking: Understanding the importance of proper blocking techniques in lens finishing processes. Students will learn to securely mount lenses onto blocking pads for subsequent edging, ensuring stability and alignment throughout the lens edging process.
Lens Edging: Acquiring advanced skills in lens edging procedures using automated edging systems. Practical sessions will cover techniques for selecting appropriate edging tools, configuring edging parameters, and executing precise lens cuts to achieve desired frame fit and aesthetic outcomes.
Coating and Lens Tinting: Exploring the application of lens coatings and tinting for enhancing visual performance and protection. Students will learn about various coating options, such as anti-reflective coatings and photochromic tints, and their benefits in reducing glare, enhancing contrast, and providing UV protection.
Base Curve, Vertex Distance: Understanding the significance of base curve and vertex distance in lens prescription and fitting. Students will learn to calculate and adjust base curve and vertex distance parameters to optimize lens performance and minimize aberrations for different prescription types and frame styles.
Throughout the course, emphasis will be placed on practical application, critical thinking, and problem-solving skills. By mastering advanced ophthalmic lenses and dispensing techniques, students will be well-prepared to meet the diverse needs of patients and excel in their professional careers in the optical industry.
