Akuvumelekile kweumbono owodwa:
Lapho abantu abangaphezu kweminyaka engu-40 ubudala, omunye pair ofizibuko zombono owodwaangase angakwazi ukuhlangabezana nezidingo zawo.Babekwazi ukubona ibanga kodwa bengasondele, noma babone eduze kodwa hhayi ibanga.Ngalesi sikhathi, kudingeka bagqoke amapheya amabili ezingilazi, izibuko zokufunda lapho besetshenziselwa ukubona izinto eziseduze nezibuko zebanga ukuze babone ibanga.Enye indlela ukugqoka izibuko ze-multi-focal, futhi izibuko ezigxile kakhulu zihlanganisaizibuko ze-bifocal neziqhubekayo.Izibuko ezigxile ezintweni eziningi ziyipheya eyodwa yezibuko ezingasetshenziswa ukubona ibanga nokuvala, ungasebenzisa ingxenye ebona kude engenhla ukuze ubone ibanga nengxenye engezansi ukuze ubone izinto eziseduze.
Uyini umehluko phakathiokuqhubekayo kanye ne-bifocal
1. I-Bifocals ikusiza ukuthi ubone kude naseduze kuphela, futhi izokhiqiza ukweqa kwesithombe uma ubheka eduze ngemva kokubona ibanga.
2. Uzothola ukubona okuqhubekayo kumabanga akude, amaphakathi, naseduze okugxilile ngamalensi aqhubekayo, futhi ngaphandle kwemigqa, akukho ukweqa kwesithombe okucasulayo.
3. ilensi eqhubekayo izobiza kakhulu kune-bifocals.Kodwa intengo eyengeziwe iyalifanelekela inani layo.
Abadingayoizibuko eziqhubekayo
1. Njengoba iso lomuntu liwohloka ngokuguga, i-lens iqina kancane kancane, okwenza iso ligxile ekukhanyeni ngemuva kunokuba libheke kuyi-retina lapho libuka izinto eziseduze.Lokhu kuyi-presbyopia.Lesi simo sivamile kubantu abaneminyaka ephakathi kanye nabadala abangaphezu kweminyaka engama-40.
2. Uma une-myopia (ukubona eduze) noma i-hyperopia (ukubona kude), udinga kuphelaamalensi ombono owodwa, kodwa uma une-presbyopia kanye neyodwa yalezo zinkinga zokubona ezimbili ngesikhathi esisodwa, udinga amalensi athuthukisa indlela obona ngayo kokubili izinto eziseduze nezikude.
3. Ezinye izinhlobo zemisebenziamalensi aqhubekayozitholakalela imisebenzi ethile.Tshela udokotela wamehlo akho uma udinga izibuko ezikhethekile ngenxa yomsebenzi.Njengokuthi uma uhamba ngemoto emgwaqeni onesivinini esikhulu, udinga ukubheka ibanga, ubone ukuthi kusele uwoyela ongakanani.
4. Ngakho-ke, uma udinga amapheya amabili ezingilazi ukuze ufunde futhi usebenzise ibanga, izibuko eziqhubekayo zingakulingana.
Ilebhu yethu ifakwe imishini evela e-Satisloh futhi ifake imiklamo yesofthiwe ye-OPTOTECH kanye ne-IOT yamalensi aqhubekayo e-freeform.Imiklamo ehlukene ifanele inhloso ehlukene.
