Opto Tech MD Progressive Lenses
Modern progressive lenses are seldom absolutely hard or absolutely, soft but rather strive for a balance between the two in order to achieve a better overall utility. A manufacturer may also choose to employ the features of a softer design in the distance periphery in order to improve dynamic peripheral vision, while employing the features of a harder design in the near periphery in order to ensure a wide field of near vision. This hybrid-like design is another approach that sensibly combines the best features of both philosophies and is realized in OptoTech‘s MD progressive lens design.
