• Lens Geometry: It explains how the curvature of a lens creates power.
• The Lens Measure (Lens Clock): Jalie famously explains how to use this tool to determine the power of a lens surface, teaching the relationship between Radius of Curvature ($r$), Refractive Index ($n$), and Surface Power ($F$).
  • Prismatic deviation
  • Prentice’s Rule (P = cF)
  • Prism base direction notation (BI, BO, BU, BD)
  • Compounding and resolving prisms
