Fig. 14From: Development of a novel multifocal lens using a polarization directed flat lens: possible candidate for a multifocal intraocular lensDigital single-lens reflex (DSLR) camera test (Far and near distance). With the monofocal lens, the building appeared very clear (A) but the letters in the ETDRS chart were very blurry at a distance of approximately 500 mm (B). With the multifocal lens, the building appeared slightly blurry (C) compared with the image from the monofocal lens, but the letters in the ETDRS chart appeared very clear (D) at a distance of approximately 500 mmBack to article page
