9. Free-form progressive lenses made from a single vision blank:
10. Digital Ray–Path technology compensates for ________ astigmatism for every gaze direction using a complete eye-lens system simulation.
11. In the near zone __________can improve acuity and enhance the reading experience in a progressive lens.
12. Free form single vision blanks produce a flatter lens in the PAL near zone which forms a more ______angle to the visual axis.
13. In a single vision front, free-form progressive digital _________is required to correct for the off-axis oblique angle in the near zone caused by flatter lenses in this zone.
