They have sport and daily version, both have different corridor length to choose, MFH of Daily will be 15mm 17mm 19mm. The Sport will have MFH 17mm 19mm 21mm which is longer corridor.
They also equipped with supreme coating which is similar to all those very smooth coating
Because they have their own freeform machine, so that they can produce safewear, polaroid, drivewear and traditional cr39 lens.
This factory first start OEM Sharmir lens almost 10 years ago, also the first factory start freeform lens production in HK.
Even the Autograph, they only sell 1 or 2 pair only !
