Molded pal lens: finished & semi
Design features
① Normal corridor combined design. Extremely low distortion among all kinds of soft-design progressive lens. As compared to E-Comfort, with a 9-12% wider on corridor, and a 5-7% lower on max unwanted astigmatism. The max unwanted astigmatism on temporal side can be amazingly controlled to lower than 70% of add value.
② Hard-soft combined design, no compromise in each viewing area
③ Wide & Stable far vision area almost can be compared to hard design. less than 5% of total add value power transition from far vision reference point to fitting center

Visual Benefits
Natural and Smooth transition between each viewing distance, very limited effect of swim or dazzle on dynamic occasions
Very easy adaption
Applications
Age 45 plus
Suitable for those who wear pal lens at first time or special sensitive wearers
Could be a good choice for those who already wear pal and seek for more comfortable economic lens
Notice
not a good choice for Mini frames or those wearers who have poor eye-ball rotation ability
