Izibuko ezithuthukisiwe ze-multifocal zasungulwa eminyakeni engama-61 eyedlule. Izibuko eziningi ezigxile ku-multifocal zaxazulula inkinga yokuthi abantu abaseminyakeni ephakathi nabadala badinga ukukhanya okuhlukile ukuze babone izinto ezikude ezahlukene futhi badinga ukushintsha izibuko njalo. Izibuko ezimbili zingabona kude, zinhle, futhi zingabona eduze. Ukufaniswa kwezibuko eziningi ezigxile ku-multifocal kuyiphrojekthi ehlelekile, edinga ubuchwepheshe obuningi kakhulu kunokufaniswa kwezibuko ze-monocal. Odokotela bamehlo abadingi nje ukuqonda i-optometry, kodwa futhi badinga ukuqonda imikhiqizo, ukucubungula, ukulungiswa kohlaka lwesibuko, ukulinganiswa kokugoba kobuso, i-Angle phambili, ibanga lamehlo, ibanga lomfundi, ukuphakama komfundi, ukubalwa kokushintsha kwesikhungo, isevisi yangemva kokuthengisa, ukuqonda okujulile kwezimiso zokugxila okuningi, izinzuzo kanye nokungalungi, njalo njalo. Uchwepheshe ophelele kuphela ongacabangela amakhasimende ngokuphelele, ukuze afane nezibuko ezifanele ze-multi-focal.
