B. Optically demanding near vision occupations.

C. Challenging prescriptions.

D. Wider fields of view with add powers over +250D.

5. Measured power in the intermediate and near zones:

A. Adjusts the front surface power of the lens to be equal to the back surface power of the lens.

C. Adjusts the Retina Forward Design for a three-dimensional field of view.

D. Adjusts the surface power of the lens for optimum performance in the as-worn position.

6. Patented 100 percent back surface technology brings the Rx closer to the eye, resulting in:

B. Expand aspheric components for clearer viewing.

C. Bring essential Rx elements closer to the eye.

D. Minimize corridor width for more focused near vision.

10. When taking Perfas lens measurements, for the best results do not:

15. One of the key benefits of moving the progressive surface from the front to the back is:

A. More pantoscopic tilt reduction and vertex distance length.

B. Clearer visual fields and less peripheral blur at near.

C. Optimized pre-molded base curve range and expanded add powers.

D. Reduction of magnification differences between visual areas.
