Lesson 1Blank lens selection: blank indexing, selecting base curve and diameter, matching index and blank specificationsThis part explains picking right lens blanks by script, material bend, base curve, and size. It covers blank marking, match with coatings, and ready versus shaped options for best light and looks in production.

It covers reading round, blur, direction, bend, and extra, plus eye space and fit height measure. You review limits, records, and talk with eye doctors and users.

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

It includes heat and press ways, lens line-up, tilt, eye space, and bridge fit checks for ease, safety, and light work in wear.

It includes eye space and height move, fix for tilt and curve, and checks to stop slip, bend, or direction faults in shaping.

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

It covers noting blank batches, machine plans, step settings, and check results, plus marking lenses and jobs for recalls, redoes, and rule follow in Uganda.
