Product Overview
Description
1）What is the progressive lens?
Modern progressive lenses, on the other hand, have a smooth and consistent gradient between differing lens powers. In this sense, they can also be called “multifocal” or “varifocal” lenses, because they offer all of the advantages of the old bi- or trifocal lenses without the inconveniences and cosmetic drawbacks.
2）The advantages of the progressive lenses.
①Each lens is customized exactly to the position of the wearer’s eye, taking into account the angles between each eye and the surface of the lens when looking in different directions, providing the sharpest, crispest image possible, as well as enhanced peripheral vision.
②Progressive lenses are line-free multifocals that have a seamless progression of added magnifying power for intermediate and near vision.

3）Minus and plus semi-finished lenses
①Lenses with different dioptric powers can be made from one semi-finished lens. The curvature of the front and back surfaces
indicates whether the lens will have a plus or minus power.
②Semi-finished lens is the raw blank used to produce the most individualized RX lens according to the patient's prescription.
Different prescription powers request for different semi-finished lens types or base curves.
③Rather than just the cosmetic quality, semi-finished lenses are more about the inner quality, such as precise and stable
parameters, especially for the prevailing freeform lens.
