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. When the eye moves from one area of vision to another, the eye adjustment process is natural and smooth, without any visual fluctuations. 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.


Types of Bifocal Lenses

Progressive multifocal lenses: a progressive multifocal lens gradually changes power from the upper part of the lens to the lower part of the lens and gives a smooth transition between the two different types of bifocal lenses. There is no distinction line in the lens. They are popular because they provide better adaption, comfort, and clarity than the other lenses.
