Invisible Bifocal

Bifocals are a great choice for wearers who are looking for an alternative to progressive lenses. This type of lenses has a special lens segment integrated into the lower part of the lens that contains additional power for near vision correction. The power difference between the lens and the segment such as in the traditional bifocals have a visible dividing line. Furthermore, the drastic power shift is usually associated with the characteristic “image jump” that the wearer experiences whenever the gaze shifts between distances. In digital generated round segment bifocals these elements are considerable reduced.

OptoTech created an advanced bifocal with improved aesthetics and greater visual comfort. We have designed Invisible Bifocal. The lens layout has been optimized to a level that the power segment is precisely blended into the lens, making the dividing line between the optical zone nearly invisible. At the same time, Invisible Bifocal’s ideal surface smoothens out the differences between the visual fields for an improved power transition, providing the wearer with a more comfortable and natural vision. This lens design can be combined with all OptoTech Design features.
