Abstract

Simultaneous vision multifocal ophthalmic lenses in contact lenses or intraocular lenses present a challenge in design and testing. The SNR represents one criterion that can aid the design in evaluating such systems. The definition of SNR as applied to such systems and an example of its use are presented here.
