A Revolution in Standard Single Vision Lenses
1. What is the name of the ZEISS technology with a patented algorithm generated from more than 300 precise patient measurements that account for the changes in the center of rotation from high plus through to high minus lenses?
2. The geometry of eyeballs differs from individual to individual. For example, a high myope typically has a 4 mm _____ eyeball than someone with perfect vision. Importantly this means that the location of a particular point in the eye – its center of rotation (CoR) – also varies by prescription.
3. With ClearView, the lens power is optimized using ________ across one entire quadrant of the lens, which is then mirrored two times to cover the whole lens surface.
4. What percentage of lenses sold globally are single vision?
5. Standard single vision lenses have a spherical or aspherical front surface, while ClearView single vision lenses are optimized with ________.
6. ClearView single vision lenses are not ___________ for Rx value based on the position of wear.
7. Image blur is a physiological-optical phenomenon, which can be calculated on defocus and:
8. Which of the following is NOT one of the four blur levels established in the ZEISS and Queensland University of Technology study?
9. Spherical, aspheric, and double aspheric lens designs do not adequately address the peripheral optics of most prescriptions, especially those with ______ power.
10. What is the name of the special manufacturing method that allows complex freeform lens designs to be delivered in stock FSV ClearView lenses?
11. The complex ClearView lens surface design is transferred into ____ designs for manufacturing.
12. A CNC freeform mold generator uses cutting tools that contain millions of ______ particles.
13. Using ZEISS industrial metrology expertise, each mold is checked for accuracy and precision, analyzing ____ points on the surface of the mold against the theoretical freeform design.
14. ZEISS CMM equipment checks 1500 points in the final step to ensure precise surface geometries of the finished lens before optical ___________ simulations are done.
15. ZEISS ClearView lenses provide ____ times larger zone of excellent vision over ZEISS aspheric SV lenses.
16. By reducing the curvature without compromising vision clarity in the lens periphery, ClearView FSV lenses are __% flatter on average across all prescriptions, with up to 49% flatter lenses for the minus range; and up to 25% flatter lenses for the plus range, when compared to ZEISS SPH 1.6 FSV.
17. In addition to less optical blur, ClearView lenses also reduce peripheral ________.
18. Based on simulation calculations on different types of distortion typically encountered by spectacle lens wearers, ZEISS ClearView lens designs showed, on average, over 4% less skew and swim distortion than a regular SPH SV lens and __% less than a regular AS SV lens.
19. Across the entire power range assessed, ZEISS ClearView FSV lenses are 34% flatter and up to __% thinner than standard SPH SV lenses while delivering the highest level of vision clarity.
20. ClearView freeform SV lens designs with point-by-point optimization provide a thickness reduction at the lens edge for minus lenses and the center for plus lenses. For example, how much thinner was a +5.00 D 1.60 index Clearview FSV lens compared to a 1.60 Index SPH FSV lens?
