Thin front-surface progressive lenses that are optimally suited to accommodating the latest in trendy eyeglass frames
TOKAI PM is a new type of progressive power lens that provides a wide, comfortable field of view pursuant to the watchword “Wide & Wide.” We incorporated technologies cultivated with our proprietary back-surface progressive design and designed these lenses to accommodate wide fields of vision across the range from near to far distances. In addition, these lenses can also be fitted to fashionable frames without any loss of performance. With an 11-millimeter corridor-length option newly added to the lineup, the selection of frames has expanded further. These are true all-around progressive lenses in the sense that they appeal to wearers for what they offer in terms of both function and style.

An 11-millimeter corridor-length option can now be selected in addition to 13-millimeter corridor-length lenses.
These are recommended for customers looking to wear more fashionable frames.

■Lenses that have given rise to new trends
TOKAI PM meets the needs of many users wishing to wear smaller frames. These lenses can also be fitted to fashionable frames without any loss of performance to effectively expand the selection of available frames and allow customers to look for eyeglasses that are a perfect match.
■Even first-time users will find these lenses easy to use
Since TOKAI PM offers a wide field of view with little swaying feelings or distortions and can even accommodate low addition, these lenses are also recommended for persons who are just beginning to develop presbyopia.
■Also optimal for wearers of eyeglasses looking to replace their lenses
Compared to conventional progressive lenses, TOKAI PM lenses offer a smoother transition between sight lights and an expanded field of near-range vision. They are also ideal for persons whose presbyopia is getting worse and who would like to enjoy a broader field of clear near-range vision. The burden placed on wearers when looking downwards has also been reduced.
