Ilensi ye-multifocal eqhubekayo
Ingabe i-lens yokugxila eminingi, i-lens surface curvature ukusuka phezulu kuya phansi ngaphambi kokukhuphuka ngokuqhubekayo, amandla aphikisayo avela esifundeni atholakala engxenyeni engenhla yelensi akude, kancane kancane, anda ngokuqhubekayo, kuze kube cishe ngaphansi kwelensi enendawo. ifinyelele inombolo cishe nge-diopter, ipheya yezibuko iyakwazi ukubona, ibanga lingabona eduze futhi, ungabona futhi ibanga lezinto. Amalensi aqhubekayo achazwa ngokuthi "amalensi asondeza," futhi ipheya yezibuko ingasetshenziswa njengepheya yezibuko eyengeziwe. Isibonelo, ilungele abafundi ukuthi bafunde futhi babhale abafundi basebenzisa i-lens (ukuhlangana nokubheka ebhodini, ukufunda izincwadi, umsebenzi wesikole kanye nezinye izidingo ezibukwayo), ilungele isixuku esimhlophe ukumelana nokukhathala kwelensi (ukuzivumelanisa nezimo Iswishi ebonwayo ekude, emaphakathi neseduze, kulula ukusebenza), ukuzivumelanisa nabantu abaneminyaka ephakathi kanye nabadala d amalensi aqhubekayo (indawo yamahhala egobile, kahle, emaphakathi, isondele ekushintsheni, hhayi ukunwebeka kobuchopho obunesiyezi).
Isingeniso Sokukhiqiza
Inkomba ye-refractive evamile ye-lens ihlanganisa: 1.56, 1.60, 1.67, 1.71, 1.74 njalonjalo. Ukuphakama kwenkomba ye-refractive ye-lens, i-lens iba mncane futhi ibe lula. Kodwa-ke, ukuphakama kwenkomba ye-refractive ye-lens, kungcono kakhulu. Ngokuvamile, ukuphakama kwenkomba ye-refractive ye-lens, inombolo ye-Abbe iphansi futhi kusobala kakhulu ukuhlakazeka.
