What are the advantages of freeform progressive lenses?
Progressive lenses place the power variation area of the lens on the back surface of the lens, making the progressive surface of the lens closer to the eye, greatly improving the field of vision and allowing the eye to obtain a wider field of vision. The power stable freeform progressive lens is manufactured by advanced free-form surface technology. The power design of the lens is reasonable, which can bring users a more stable visual effect and wearing experience. It is easy to adapt to freeform progressive lenses because they are closer to the eyeball and the shaking feeling on both sides of the lens after wearing is smaller.As a result,it reduces the discomfort of first-time wearers and makes it easier to adapt so that users who have never worn glasses can quickly master the use method.
