Lesson 1Blank lens selection: blank indexing, selecting base curve and diameter, matching index and blank specificationsThis part explains choosing the right lens blanks based on the script, material power, base curve, and size. It includes blank coding, matching with coatings, and deciding between ready-made or shaped blanks for best sight and appearance.
