Abstract:
A multifocal lens supply system including a multifocal lens ordering computing unit and a multifocal lens determination computing unit, for providing to a wearer a customized progressive spectacle ophthalmic lens having a customized addition Addc, wherein Addc=Addp+corr, wherein corr is a corrective value which is the output of a function where the input is at least an individual wearer parameter value and at least an output value over the input range is different from nil, and wherein Addp is a prescribed addition.
Abstract:
A system for the supply of ophthalmic lenses and related methods for providing ophthalmic lenses for enhanced experience based on right-handedness and left-handedness.
Abstract:
The visual perception of a lens wearer is not only along the gaze direction, but also has a non-zero transverse extension, which is called perceptual span. Perceptual span is skewed to extend further in the reading direction, i.e., the line portion to be read next relative to the line portion that was just read. A technique is provided that determines a pair of progressive ophthalmic lenses that take such perceptual span into account.
Abstract:
A process for determining a pair of personalized progressive ophthalmic lenses. and a computer program product associated to these processes. Right-handed persons and left-handed persons behave very differently when executing certain near vision tasks, such as writing on a sheet of paper. However, current lens designs do not take into account these behavior differences. The comfort of wearing a pair of ophthalmic lenses can be improved for the wearer for whom the lenses are intended by adapting his near vision according to his handedness.
