①Function enhanced ultra-short corridor hard design. The add value from FC to NRP occupies 95% of total value with a 13 mm only total corridor length.
②Ultra wide and stable far-vision area with a total clear viewing angle below 0.5 cyl line at both FRP and FC.
③Comparatively low distortion among ultra-short corridor lens, as to compared to traditional ultra-short corridor pal, with a 10-12% wider corridor and max unwanted astigmatism lower than 90% of add value.
