Customized Multifocal Lenses
Multifocal eyeglasses have long since become a basic requirement in optometry, in light of the distinct advantages, headed by the elimination of the need to switch eyeglasses to reading glasses.
Unlike the past, a non-professional cannot determine whether the eyeglass lens are regular or multifocal since there is no line across the lens as had been the case in the past (bifocal lens)
Customization of multifocal lenses is critical: the more accurate the customization is based on the specific individual’s requirements, the faster and smoother their adjustment.
Customization of multifocal lenses is complex, requiring tremendous expertise and patience, since among the considerations that need to be taken into account when customizing multifocal lenses are:
- The selected frame and its specifications
- Pantoscopic tilt (frame curves)
- Exact pupil distance – Pd
- Pupil height
- Correct selection of lens type, taking into account the production technologies that allow, inter alia, an expanded field of vision, soft transitions between distance and proximity, lens design based on luminance, individual fit as dynamic visual ranges – etc.
