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

Visual Benefits
Clear-wide far vision and stable easy-to-reach reading area, both good for driving and reading
Improved adaption as compared to traditional hard design
Applications
Age: 45 plus
Most suitable for those who have been adapted to progressive lens who likes both wider far-vision and reading area.
Good choice for wearers with poor eye-rotation ability or Mini frame lovers
Notice
Not a good choice for those distortion sensitive people
