Muhupenyu, tinogara tichitarisa nzvimbo dzakasiyana kubva kure kusvika kure, izvo zviri nyore kune shamwariwo zvayo, asi zvakasiyana kune vanhu vane maziso asina kunaka, iro dambudziko rinotambudza kana rinotambudza.
Nzira yekugadzirisa sei dambudziko iri?Zvechokwadi ndiwo magirazi ekubatsira, vanhu vane myopic vane magirazi, vanogona kuona kure, vanhu vanoona kure vane magirazi vanogona kuona pedyo, asi dambudziko rinouya, kupfeka magirazi kuona kure, kana kutarisa pedyo, kunenge kusinganzwisisike, uye zvakafanana. nekupfeka magirazi kuti vaone pedyo.Nzira yekugadzirisa sei dambudziko iri?Ikozvino pane mhinduro kune iyi kusagadzikana: inofambira mberi multifocal magirazi.
Ndiyo nyaya yechinyorwa ichi - inofambira mberi multifocal lenses.
Progressive multifocal lenses, anozivikanwawo seanofambira mberi lenzi, ane akawanda anotarisisa mapoinzi pane imwe lenzi sekureva kunoita zita.Kana iyo lenzi yakakamurwa kubva pakutarisa, iyo lenzi inogona kupatsanurwa kuita imwechete yakatarisa lens, kaviri focal lens, multi focal lens.
· Malenzi edu akajairika ndeaya-akatarisana lenzi, uko kune kupenya kumwe chete pane lens;
· Bifocal lens i bifocal lens, iyo yaimboshandiswa nevakwegura vakawanda kugadzirisa dambudziko rekuona kure nepedyo panguva imwe chete.Nekudaro, nekuda kwekukanganisa kwayo kukuru uye kufarirwa kweinofambira mberi yakawanda-yakatarisana, bifocal lens yakabviswa zvachose;
· Sechiitiko chakakosha munhoroondo yekuvandudza lens, multifocal lens ichavewo nhungamiro huru yekutsvagisa kweramangwana nekusimudzira uye kukurumbira kwemusika.
Kuzvarwa uye kusimukira Nhoroondo yeinofambira mberi multifocal lens:
Muna 1907 Owen Aves akatanga kuisa pfungwa yekufambira mberi multifocal lens, zvichiratidza kuzvarwa kwechiratidzo chitsva chekugadzirisa.
Magadzirirwo eiyi lens akakosha anofemerwa nechimiro chehunde yenzou.Kana iyo curvature yepamberi ye lens ichiwedzerwa zvichienderera kubva kumusoro kusvika pasi, iyo refractive simba inogona kuchinjwa zvinoenderana, kureva, iyo refractive simba rinowedzera zvishoma nezvishoma uye nekuenderera kubva kunzvimbo iri kure iri kumusoro kwenzvimbo. lenzi kusvika nzvimbo yepedyo pazasi pe lens inosvika painodiwa padyo nenhamba ye diopter.
Pahwaro hwekutanga kubata pamuviri, uye nerubatsiro rwezvitsva zvakabudirira mukugadzira uye budiriro inopiwa nehunyanzvi hwemazuva ano, muna 1951, murume wechiFrench Metenez akagadzira yekutanga lens inofambira mberi yepfungwa yemazuva ano, inogona kushandiswa pakupfeka kwekiriniki.Mushure mekunatsiridzwa kwakawanda, yakatanga kuendeswa kumusika weFrance muna 1959. Pfungwa yaro yekuvandudza yekuona yakawana kutariswa kwepasirese uye nekukurumidza yakaunzwa kune continent yeEurope neNorth America.
Nekuvandudzwa kwekombuta uye kushandiswa kwesoftware yemhando yepamusoro uye zviridzwa mukugadzira nekusimudzira magirazi emaziso, inofambira mberi lens dhizaini yakawana budiriro huru.Mafambiro akajairika ndeekuti: kubva kune imwe chete, yakaoma, symmetric uye spherical kure-zone dhizaini kune akasiyana, akapfava, asymmetric uye aspheric kure-zone dhizaini.Mukutanga dhizaini yegirazi inofambira mberi, vanhu vainyanya kufunga nezvemasvomhu, mechaniki uye matambudziko emaziso.Nekunzwisisa kwakawanda kweiyo yekuona sisitimu, yemazuva ano uye yeramangwana inofambira mberi yegirazi dhizaini ichawedzera kutarisa pahukama pakati pegirazi rinofambira mberi uye physiological optics, ergonomics, aesthetics, psychophysics.
Mushure mekuvandudzwa kwakakura kwakati wandei, lenzi inofambira mberi yave sarudzo yekutanga kugadzirisa maonero munyika dzekuMadokero kweEurope dzakasimukira dzakaita seFrance neGermany, nemhando dzakawanda dzemalenzi uye vanhu vazhinji vanopfeka lens inofambira mberi.MuJapan neUnited States, kupfeka kwemalenzi kunofambira mberi kune kuwedzera kuri pachena gore negore.Munharaunda yeAsia-Pacific neEastern Europe, nekusimudzirwa kwedzidzo yeOptometry makosi ane inofambira mberi lens inokodzera semusimboti, vazhinji uye vazhinji veOptometrists neOptometrists vanoona inofambira mberi lens sesarudzo yakakosha yekugadzirisa maonero.
Ndiani anofambira mberi multifocal lens akakodzera?
1. Chinangwa chepakutanga che-multi-focal lens ndechekupa yakasikwa, yakanakira uye yakagadzika nzira yekugadzirisa kune varwere vepresbyopia.Kupfeka lens inofambira mberi kwakangofanana nekushandisa vhidhiyo kamera.Magirazi maviri anogona kuona zviri kure, zviri pedyo uye zviri pakati nepakati zvinhu zvakajeka.Naizvozvo, tinotsanangura malenzi anofambira mberi se "malenzi anokwenya".Mushure mekupfeka magirazi maviri, zvakaenzana nekushandisa magirazi akawanda.
2. Nekutsvakurudza kwe "myopia development and regulation theory", inofambira mberi multifocal lenses yakashandiswa zvishoma nezvishoma kudzora kukura kwe myopia muvechiri kuyaruka.
Zvakanakira zvekufambira mberi multifocal lens
1. Kuonekwa kwe lens kwakafanana neye monophoscope, uye hapana mutsara wekuparadzanisa wedhigirii shanduko inogona kuonekwa.Kunaka kwelenzi kunodzivirira kudiwa kwemupfeki kuchengeta zera rake zvakavanzika, uye kubvisa kunetseka kweanopfeka nezvekuburitsa zvakavanzika zvezera rake nekupfeka bifocal munguva yakapfuura.
2, shanduko yedhigirii lens nhanho nhanho, haizoburitse mufananidzo kusvetuka.Kugadzikana kupfeka, nyore kugadzirisa.
3, iyo lens dhigirii zvishoma nezvishoma, kubva kure kusvika pedyo nekuchinja kwekuwedzera zvishoma nezvishoma, haizobudisi kuchinja kwekugadzirisa maziso, kwete nyore kukonzera kuneta kwekuona.
4. Chiono chakajeka chinogona kuwanikwa pamadaro ose mukati mechikamu chechiratidzo.Magirazi maviri anogona kushandiswa kure, kure uye pakati nepakati panguva imwe chete.
Chengetedzo yekufambira mberi multifocal lens
1. Paunenge uchifananidza magirazi, sarudza furemu yakakura.
Nekuti iyo lens inofanirwa kukamurwa kuita nzvimbo dziri kure, dzepakati, uye dziri pedyo, furemu hombe chete ndiyo inokwanisa kuona nzvimbo yakafara yakakwana yekushandisa pedyo.Zvakanakisa kuenzanisa iyo yakazara furemu furemu, nekuti yakakura iyo lens, iyo yakakora iyo lens mupendero, yakazara furemu slot inogona kuvhara ukobvu hwema lens edge.
2 kazhinji inoda vhiki yenguva yekujaira, asi kureba kwenguva yekuchinja kunosiyana pamunhu nemunhu, famba zvishoma nezvishoma kana uine dzungu.
3. Nemhaka yokuti mativi maviri e lens ari astigmatic disorder area, zvakaoma kuona zvinhu zviri kumativi ose kuburikidza nechiedza chinopenya bhora, saka zvakakosha kutenderera mutsipa uye ziso panguva imwe chete kuti uone zvakajeka.
4. Paunodzika pasi, chengetedza magirazi ako pasi uye edza kuona kunze kwenzvimbo iri kumusoro.
