Lesson 1Blank lens selection: blank indexing, selecting base curve and diameter, matching index and blank specificationsThis lesson explains picking right lens blanks by script, material bend, base curve, size. It covers blank codes, coating match, and ready vs shaped options for best sight and looks.

It covers reading round, blur, angle, bend, add, plus eye space and height measure. You review limits, records, talk with doctors and patients.

It covers edge shapes, slot depth, thickness control, safe edges, stop chips or cracks in high-bend and no-rim designs.

It includes heat pressure ways, lens line-up, tilt, eye distance, bridge fit for comfort, safety, sight work.

It includes space and height move, fix for tilt and bend, checks to stop slip, bend, angle errors in shaping.

It covers cure times, clean control, stick tests, sight check for colour, faults, evenness.

It covers noting blank batches, machine plans, step settings, check results, plus label lenses and jobs for recalls, redoes, rules follow.
