Muhupenyu, isu tinogara tichitarisa kunzvimbo dzakasiyana kubva kure kusvika kure kusvika kure, izvo zviri nyore kwazvo kushamwari dzakajairwa, asi dzakasiyana vanhu vane maziso asina kunaka, iri dambudziko rinotambudza kana rinotambudza.
Maitiro Ekugadzirisa dambudziko iri? Zvirokwazvo ndiyo aubhilial prop magirazi, vanhu veMyopic vane magirazi, vanogona kuona vanhu vari kure, asi dambudziko racho rinogona kuona vari pedyo, asi vakapfeka magirazi kuti vaone kusvika kure, kana vachitarisa pedyo, vachasarongeka, uye zvakafanana nekupfeka magirazi kuti uone pedyo. Kuita zviri nani kugadzirisa dambudziko iri? Ikozvino pane mhinduro yeiyi kushungurudzika uku: inofambira mberi magirazi emizhinji.
Ndiyo nyaya yechinyorwa ichi - inofambira mberi midzi wentific lens.
Kufambira mberi kwenyika multificeal lenses, anozivikanwawo seanofambira mberi lenses, ane akawanda mapoinzi ezvinyorwa pane imwe lens sezita rinoreva zita. Kana iyo lens ikakamurwa kubva pane zvakatemwa, iyo lens inogona kukamurwa kuita single fens, kaviri fens, makawanda fens lens.
· · Yedu kakawanda malensi ane magetsi asina kujairika, apo kune imwechete luminsity pamhepo;
· Bifodocal Lens inhenyo dzebhaibheri, dzaishandiswa nevanhu vazhinji vakura kugadzirisa dambudziko rekuona kure uye pedyo nenguva imwe chete. Nekudaro, nekuda kwekukanganisa kwayo kukuru uye mukurumbira wekufambira mberi kazhinji-kufambira mberi, manhamba ebhaibheri akabviswa chaizvo;
· Sechikamu chikuru munhoroondo yekuvandudza lens, lens multificeal ichavewo nzira huru yekutsvaga ramangwana rekutsvaga uye kusimudzirwa nemusika.
Kuzvarwa uye Budiriro Nhoroondo yeCross IlwereChiFocal Lens:
Muna 1907 owen owen anotanga aisa pfungwa yeiyo pfungwa yekufambira mberi midzi-midzi-kuwanda, ichimisa kuberekwa kwechiitiko chitsva chekugadzirisa pfungwa.
Kugadzirwa kweiyi lens kwakakosha kwakafemerwa nechimiro chegwenzi renzou. Kana iyo curvature pamusoro peiyo lens inowedzera kubva kumusoro kusvika kumusoro, simba rekudzora rinogona kuchinjwa maererano, ndiko kuti, iro simba rekutsoropodza rinowedzera zvishoma nezvishoma uye rinoramba richiripo munzvimbo iri kumusoro kweiyo chikamu chepamusoro che Lens kusvikira iyo nzvimbo iri pedyo pazasi pemaruva inosvika pane inodiwa pedyo neDiopter nhamba.
Pahwaro hwekutakura kwekutanga, uye nerubatsiro rwezvakanyanya kubudirira mune dhizaini uye nekuvandudza zvakapihwa nehunyanzvi hwemazuva ano, murume weFrance metenez akagadzira lens yekutanga yepfungwa yemazuva ano, iyo inogona kushandiswa kupfeka zvekiriniki. Mushure mekunatsa kwakawanda, zvaitanga kuunzwa kumusika weFrance muna 1959
Nekuvandudzwa kwekombuta uye kushandiswa kweiyo advanced dhizaini yekugadzira uye zviridzwa mukugadzirwa uye kusimudzira kwezviratidzo zvezviratidzo, kufambira mberi kwelens kugadzirwa kwacho kwakaita kukura kukuru. Iyo General Trend ndeye: Kubva pane imwe chete, yakaoma, symmetric uye inonhuwirira kure-zone dhizaini kuti iitike, yakapfava, asymmetric uye asperic one dhizaini dhizaini. Mukutanga dhizaini yegirazi rinofambira mberi, vanhu vanonyanya kutaridzika semanyeka emasvomhu, zvemuchina uye zvemitambo. Nekunzwisisa kwakazara kweiyo inoonekwa system, yemazuva ano uye yemazuva ano uye ramangwana kufambira mberi kwegirazi kuchawedzera kutarisa nezvehukama huremu hwemirazi nepfungwa, ergonomics, eresthetics, pseschophys.
Pashure pokunge midziyo mikuru yakati wandei, lens inofambira mberi yave yekutanga sarudzo yekuzviruramisa kuWestern nyika dzakasimukira senge France neGermany, zvine marudzi mazhinji ezvinyorwa uye vanhu vazhinji vanopfeka lens. MuJapan neUnited States, kupfeka kunofambira mberi kunopfeka kune kwakajeka maitiro ekuwedzera gore rega rega. MuAsia-Pacific Dunhu uye Eastern Europe, nekusimudzirwa kweOptometry Dzidzo Courses neCons Itsvano dzakakodzera semubatanidzwa, more optometrists kufambira mberi lens kufambira mberi kwesarudzo yakakosha yekuzviruramisa.
Ndiani anofambira mberi marudzi mazhinji enhema akakodzera?
