Features of progressive lenses

With the proper head position, the wearer can have a clear and continuous vision at all distances from the distal point to myopia through the progressive lens.

With natural vision and better adaptability, it is in line with physiological optics. The mid and near vision area is relatively small: Some wearers may feel that the gradient area of the progressive lens is smaller, which limits the width of the saccadic eye and requires increased head movement in order to achieve the same reading range. At medium and short distances, the wearer needs to coordinate certain head movements.
