This lecture-style course breaks down the physics of lens materials in an accessible, practical way. Participants will learn how refractive index, Abbe value, and specific gravity impact lens thickness, weight, and visual clarity. Through simple analogies and real-world examples, attendees will discover why a 1.74 lens isn’t always the best solution, how to balance cosmetic and visual needs, and how to explain these complex concepts to patients confidently.
Learning Objectives:
Upon conclusion of this activity, attendees will be able to:
Understand the key properties of lens materials
Learn how index, Abbe value, and specific gravity impact lenses
Apply these concepts to real-world dispensing challenges
