Amalensi aqhubekayo angamalensi eqiniso “e-multifocal” ahlinzeka ngenani elingapheli lamandla amalensi kupheya eyodwa yezibuko. I-Optimum-vision isebenzisa ubude belensi ukuvumela ibanga ngalinye ukuthi licace:
Phezulu kwelensi: ilungele ukubona ibanga, ukushayela, ukuhamba.
Maphakathi nelensi: ilungele ukubona ikhompyutha, amabanga amaphakathi.
Phansi kwelensi: ilungele ukufunda noma ukuqedela eminye imisebenzi eseduze.
Njengoba sikhula, kuba nzima nakakhulu ukubuka izinto eziseduze kwamehlo ethu. Lesi yisimo esivame kakhulu esibizwa ngokuthi i-presbyopia. Abantu abaningi baqale baqaphele lapho benenkinga yokufunda imibhalo ebhalwe kahle, noma lapho bephathwa ikhanda ngemva kokufunda, ngenxa yokucindezeleka kwamehlo.
Ama-Progressives ahloselwe abantu abadinga ukulungiswa kwe-presbyopia, kodwa abafuni umugqa oqinile phakathi kwamalensi abo.
Ngamalensi aqhubekayo, ngeke udinge ukuba nezibuko ezingaphezu kweyodwa nawe. Awudingi ukushintsha phakathi kokufunda kwakho kanye nezibuko ezijwayelekile.
Umbono onokuthuthuka ungabonakala ungokwemvelo. Uma ushintsha ekubukeni okuthile eduze kokuthile okukude, ngeke uthole "ukweqa" njengoba ubungenza ngama-bifocals noma ama-trifocals.
Kuthatha amaviki angu-1-2 ukulungisa intuthuko. Udinga ukuziqeqesha ukuze ubuke engxenyeni engezansi yelensi lapho ufunda, ubheke phambili uqonde ibanga, futhi ubheke ndawana thize phakathi kwezindawo ezimbili zebanga eliphakathi nendawo noma umsebenzi wekhompyutha.
Ngesikhathi sokufunda, ungase uzizwe unesiyezi kanye nesicanucanu ngenxa yokubheka ingxenye engafanele yelensi. Kungase futhi kube nokuhlanekezelwa okuthile kokubona kwakho okuseceleni.
Njengoba izibani eziluhlaza okwesibhakabhaka zikhona yonke indawo namuhla, ama-anti-blue Progressive Lens alungele imisebenzi yasendlini, njengokubuka i-TV, ukudlala kukhompuyutha, ukufunda izincwadi nokufunda amaphephandaba, futhi afanele ukuhamba ngezinyawo ngaphandle, ukushayela, ukuhamba nokugqoka kwansuku zonke unyaka wonke.
