Akuvumelekile kweumbono owodwa:
Lapho abantu beneminyaka engaphezu kwengu-40, umbhangqwana owodwaIzibuko zombono owodwakungenzeka ingakwazi ukufeza izidingo zayo. Babekwazi ukubona ibanga kodwa bangavali, noma bangabona eduze kodwa hhayi ibanga. Ngalesi sikhathi, badinga ukugqoka ngazimbili izibuko ezimbili, ukufunda izibuko lapho bekusetshenziselwa ukubona izinto eziseduze nezibuko zebanga ukubona ibanga. Enye indlela ukugqoka izibuko eziningi ezigxile ezindabeni, futhi izibuko eziningi ezigxile zifakaIzibuko ze-Bifocal and Progressive. Izibuko ezigxile eziningi ziyi-pair of izibuko zingasetshenziswa ukubona ibanga futhi zivale, ungasebenzisa ingxenye engenhla enkulu ukuze ubone ibanga nengxenye engezansi ukuze ubone ibanga eliseduze.
Uyini umehluko phakathiProgressive and BIFOCAL
1. I-BIFOCALS ikusiza ukuba ufike kude futhi eduze nombono kuphela, futhi uzokhiqiza ukugxuma kwesithombe lapho ubukeka useduze ngemuva kokubona ibanga.
2. Uzothola umbono oqhubekayo ezindaweni ezikude, eziphakathi nendawo, naseduze ezigxile eziphezulu nge-lens eqhubekayo, futhi ngaphandle kwemigqa, akukho sithombe esicasulayo seqa.
3. Ilensi ethuthukayo izobiza kakhulu kunama-bifocals. Kepha intengo eyengeziwe ifanelwe ukubaluleka kwayo.
OdingaIzibuko ezithuthukayo
1. Njengoba iso lomuntu liyancipha ngokuguga, kancane kancane i-lens lisebenza kancane, okwenza iso ligxile ngemuva kunokuba libheke izinto ezisondelene. Le yi-Presbyopia. Le nto ivamile phakathi kwabantu abaneminyaka ephakathi nabantu asebekhulile ngaphezulu kweminyaka engama-40.
2. Uma une-myopia (esondele) noma i-hyperopia (ekungabiseni), udinga kuphelaAmalensi wombono owodwa, kepha uma une-presbyopia nenye yalezo zinkinga ezimbili zombono ngasikhathi sinye, udinga amalensi athuthukisa indlela obona ngayo izinto eziseduzane nasezindaweni ezikude kakhulu.
3. Ezinye izinhlobo zokusebenzaAma-lens athuthukayoziyatholakala ngemisebenzi ethile. Tshela udokotela wakho wamehlo uma udinga umfana okhethekile wezibuko ngenxa yomsebenzi. Njengokuthi uma ushayela imoto ngomgwaqo wejubane eliphezulu, udinga ukubheka ibanga, futhi ubone ukuthi kusele uwoyela ongakanani.
4. Ngakho-ke, uma udinga amabhangqa amabili ezingilazi zokufunda nokusetshenziswa kwebanga, izibuko ezithuthukayo zingakufanele.
Ilebhu yethu ifakwe ngemishini evela ku-satisloh futhi ifake ama-OptoTotech kanye ne-IOT software design for freeForm lens lens.Imiklamo ye -difeferent ilungele inhloso ehlukile.
