What will I learn?
Gain mastery over converging and diverging lenses through this targeted course that connects essential formulas, ray tracing techniques, and practical prescription applications. You will learn the lens makers’ formula, thin-lens equation, sign conventions, and optical power calculations, then use them for precise ray descriptions, material selection including high-index lenses, and clear clinical explanations to communicate effectively, verify results numerically, and make assured lens choices.
