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