Best Designer Prescription Hmc/Hc/UC Coating UV420 1.56 Blue Cut Progressive Optical Lens

1.56 blue cut progressive optical lens
External progressive lens series, the use of asymmetric design, to provide good left and right eye visual balance, lens center to lens edge light transit gently, reduce lens edge aberration astigmatism, clear distal and proximal visual field area, so that the wearer's vision is more natural, adapt more quickly. Left and right asymmetric design and transmitted light tracking design, lens peripheral deformation is smaller, unique soft design, the close-up field of view widened, to make it easier for close-up users to adapt.
