Lesson 1Blank lens selection: blank indexing, selecting base curve and diameter, matching index and blank specificationsThis lesson shows picking lens blanks by script, material bend, base curve, size. It covers indexing, coating match, and stock vs shaped options for best sight and style.
Reading and decoding blank package labelsChoosing base curve by Rx and frame wrapSelecting blank diameter for decentrationMatching refractive index and material familyStock versus semi-finished blank decisionsLesson 2Prescription intake and verification: interpreting sphere/cylinder/axis/Add, PD and fitting height measurement best practicesThis lesson stresses accurate script handling and checks. It covers reading round, cylinder, angle, extra, plus eye spacing and height measures, tolerances, notes, and talks with doctors and clients.

It covers bevel shapes, slot depth, edge control, safety edges, avoiding chips or cracks in thin or rimless lenses.

Includes heat/pressure, alignment, face tilt, eye distance, bridge fit for comfort, safety, and sight quality.

Includes eye spacing/height shift, tilt/wrap fix, checks against slip, warp, angle errors in shaping.
