Endless Bifocal

Free-form round segment bifocal lens. Expands material and treatment options for wearers.

Endless Bifocal lenses are created with free-form technology on the back side of any semi-finished spherical lens blank. Digital processing ensures the segment line is virtually invisible for noticeably better aesthetics. Lens structure is very similar to conventional bifocals. Material availability is consistent with other digital free-form lenses.

Endless Bifocal lenses are fully personalized using Digital Ray-Path 2 Technology. Oblique aberrations are reduced allowing wearers to focus with precision.

Endless Bifocal | Round

The diameter (32 mm) and position of the segment are very similar to a conventional bifocal with straight, curved, or round segments. This solution is perfect for those who already wear bifocal lenses and want easy adaptation to their new eyeglasses.

Endless Bifocal | Wide

In this configuration, the segment is expanded up to 40 mm, offering a noticeably larger near viewing area while maintaining panoramic distance vision. This configuration is ideal for current wearers of wide segment conventional or executive bifocals. It is also optimal for vision therapy for children with accommodative difficulties.

    In addition to mathematically compensating for oblique aberrations, IOT Digital Ray-Path 2 adds the intelligent use of the wearer’s accommodation: the small power adjustments the eyes naturally make to view objects at different distances. Lenses customized with this technology have drastically reduced oblique aberrations across the entire field of vision. They are more comfortable, have impeccable visual quality, and more precise focus.

    Pushing the limits of geometry in lens personalization

    Digital Ray-Path 2 pushes the limits of geometry in lens personalization by incorporating the wearer’s accommodative capacity in the final lens calculation to further minimize oblique aberrations.

    Oblique aberrations, found in any lens, include astigmatic and spherical power errors. These errors create an out-of-focus image as the wearer’s gaze moves away from the optical center of the lens. Eliminating them completely is not mathematically possible. Some residual power error remains, causing a slight blur.

    The eye lens system
    First, it creates a simulation of the complete system that includes the eye and considers all available information on the wearer, frame, and lens blank.

    Accommodative object space
    Next, it incorporates the wearer’s natural ability to accommodate including the accommodative object space, the visual range associated with each direction of gaze.

    Minimization of oblique aberrations
    Finally, it analyzes and minimizes oblique aberrations at various distances and for each direction of gaze over the entire accommodative object space. The result: extremely clear vision and precise focus.
