Ngenxa enkulu kangaka Ukuhlelwa wonke ungakhetha ngokwabo intle umgangatho kunye nexabiso ukhetho. Kwaye kukhetha kube lula ukuba banikele kuwe baqhelane yintoni na lenses (iintlobo kunye neentlobo). Kwakhona uya kufunda indlela inkqubo yokukhetha yabo sihlolisise izincomo ononophelo.

A bit yomlando

lenses, kwakunye iiglasi - le ndlela non-yokusebenza yokukhuza mbono. Ngokuba lixesha kuqala ukuba ukuthetha uLeonardo da Vinci ekuqaleni kuka 1500. Emva 387 kweminyaka glassblower German kunye Mueller wenza ilens iglasi, leyo zibekwe iliso isigulana. Ukususela ngoko, iinzame eziliqela zokwakha umgangatho nje kuphela, kodwa lenses contact ekhululekile iye yenziwa.

Ngowe-1960 kwafika lens yokuqala ezithambileyo kunye neminyaka elishumi kamva amalungiselelo imveliso yazo mass. Kule minyaka yenziwe iintlobo iinkampani eziphambili ubugcisa obutsha kunye namandla kuye, kwakunye nezinto kunye umphezulu imbonakalo, kunokwenzeka ukuba ukunxiba iilensi ngaphandle kokususa, ngaphandle kokunikezela impilo njalo njalo.

market Namhlanje inikeza ezininzi ezahlukeneyo lens, ezingenzelwanga kuphela ukulungisa umbono, kodwa kwakhona ukutshintsha umbala ngokwendalo inwebu. Kodwa ke, nangona oku, zonke brand izama ukwandisa ngakumbi line-up for lula kubasebenzisi bayo kwaye akafuni siyeke uphuhliso iintlobo ezintsha. Ngokomzekelo, namhlanje iindidi "Acuvue" iilensi zoqhagamshelwano zezi:

• ngokuba abantu ukubona okanye ezikude - usuku olunye, wear eyandisiweyo, ezemidlalo, ngebhegi, kwiveki ezimbini-, nasekubalungiseni ize ipolishi;
• ngokuba abantu astigmatism - ngosuku olunye-neeveki ezimbini.

Ezahlukahlukeneyo lenses

Ukuza kuthi ga ngoku, kukho ukuhlelwa iimpawu ezifana:

• ngokuxhomekeke kwimveliso izinto: soft and nzima;
• ngokususa igama elithi: yonke imihla, inxalenye (noomama) ecwangcisiweyo, icwangciswe (nge nyanga, ikota, iinyanga ezintandathu);
• kweeseli iindlela: yonke imihla, bhetyebhetye, elide kunye wear ngokuqhubekayo;
• Special: skleriticheskie, orthokeratology, hybrid;
• izithambiso: umbala kunye ithinti.

lens contact Soft

lens contact Soft zezona hlobo luqhelekileyo. Bona eyabelwe abantu hyperopia, ukubona, astigmatism kunye presbyopia. Kananjalo kusetyenziselwa iinjongo zonyango (umz, xa kukho imfuneko yokuzisa amachiza zibe esweni okanye abakhusele ukuze kukhawuleziswe inkqubo yokulungisa).

eziluncedo zabo:

• ukhululekile ukuba athwale;
• ikhono lokunciphisa ukufuma;
• ukukwazi ukuba kudlule umoya;
• ukuba uziva kwi retina.

Iintlobo lens contact soft:

• hydrogel - iqukethe ipesenti ephezulu ukunyakama, kwaye umphezulu lowo kakuhle kakhulu, inokusityeda kunye elastic;
• abicah hydrogel - lubonakala lizinga eliphezulu ioksijini permeability, yaye baqhubeka kakuhle imilo zabo.

Olu hlobo lisusiwe xa kukho iziphene le inwebu. Ngenxa nezimo lens akanaye yifuna. Le ethile ye lens ezinjalo kukuba xa zomile zibe nzima kwaye aphuke, ukuze zingagcinwa kuphela isisombululo ekhethekileyo. bafuna nabo Ukuphathwa ngenyameko kuba angaphula ngokulula.

lens engaguquki

lens contact ezingamaphepha emiselweyo ophthalmologists kwiimeko apho ogulayo utshintsho imilo inwebu, zibe mazilungiswe ngoncedo uhlobo ethambileyo. Oku kunokuba, umzekelo, astigamtizm. lithathelwe kuthatha ixesha elithile. Ekuqaleni, baziva kunxitywe phezu kwamehlo. Oku ngokukodwa waziva ngexesha ukuqhwanyazaemva. Eyona iphambili lenses nzima - zenziwe kwiilebhu ekhethekileyo ngamnye parameters yomguli, njengoko ufuna kungqamana ngqo umphezulu engaphakathi inwebu lens.

Iintlobo lens zoqhagamshelwano avezwa uhlobo amehlo:

• gas-tight - kubo ntoni ukungena ioksijini;
• igesi akubonakali.

Izinto eziluncedo zezi lens:

• okuhlala;
• kuhle ugcine isimo sabo;
• ukubonelela imifanekiso ecacile zitsolile;
• lula icocwe yokungcola.

Ngokutsho manani, 10 kuphela% ezigulane benxibe lenses nzima ehlabathini lonke. I-90% isetyenziselwe ezithambileyo.

uhlobo nzima uboniswe lweefomu okunzima astigmatism kunye keratoconus. Xa inkqubo lens ezinjalo kusetyenziswa izinto ngqongqo. Baqale lonke ixesha emehlweni akhe wena blink nenkqubo habituation ithatha ixesha. Kodwa olu hlobo igcina ngokupheleleyo imilo kunye ixesha elide, kodwa, njengoko umthetho, akubangeli negazi lakho, njengoko iidipozithi kwi lens nzima abhalwe kancinci ngaphezu kwimeko lens ezithambileyo.

Ngokususa igama elithi

Ixesha wokususa lenses - ixesha iseti ixesha ngumvelisi, leyo enokusetyenziswa lenses contact. Ngokutsho kokuphela sibini endala kufuneka kufakwe ezintsha.

• replacement imihla ngemihla: yonke imihla, unxibe izihlangu entsha. Le mbono inika intuthuzelo ubuninzi yaye kuqinisekisa ukusetyenziswa eliphezulu nesempilweni. Esi sithintelo lixabiso phezulu.
• Rhoqo replacement ezicwangcisiweyo: nezihlandlo ngokubeka phezu izihlangu ezintsha iiveki enye okanye ezimbini okanye inyanga enye. Olu hlobo yeyona ilungileyo ngokwemiqathango nexabiso kunye nokusetyenziswa zisempilweni. lens Faka kunokuba iintsuku eziliqela ngaphandle kokuthatha off.
• indawo olucwangcisiweyo. Zahlula-hlulwe ngenyanga, ngekota kunye achazayo wesiqingatha-sonyaka. Yeyona ndlela kakhulu nenoqoqosho. Nangona yokuba abanganyangekiyo ukuyilwa protein kunye neprothini nokufumba, lo yokulahlwa kwe-micro-eziphilayo ukuze bafikelele kwinqanaba eliphezulu nococeko kuyimfuneko ukusebenzisa izisombululo ezikumgangatho ophezulu ngenxa ukucoca yabo. lens ezinjalo musa ukunika ithuba yokonakala rhoqo phezu ebusuku kwaye kucetyiswa ukuba ukususa emva kweeyure 15.

Kufuneka kufakwe emva kwexesha elibekiweyo lokuthath'indawo zonke iintlobo lenses contact. Neempawu zazo, kwaye inqanaba wokuhla lococeko ekuhambeni kwexesha, kwaye oku kuchaphazela kuphela umgangatho umfanekiso, kodwa kwimpilo iliso.

Ngokutsho indlela wokufaka

Oku akufani loo ngotshintsho. ukunxiba imo kuthetha ixesha ubuninzi bexesha apho awukwazi ukususa lenses contact. Kungenxa iimpawu ezithile umbandela ukusuka apho zenziwe, kwakunye kokutshintsha kota.

ethwele indlela ingaba oku kulandelayo:

• ngosuku (DW): lensi banxibe kusasa, wazisusa ebusuku;
• abongi (FW): ivumela iperi lens kulala ebusuku elinye okanye amabini;
• ixesha elide-obambeleyo (EW): Iinkcukacha lens yolu hlobo unako ukuthwala ukuya kwiintsuku ezintandathu ngaphandle wayisusa;
• oluqhubekayo (CW): enxibe imo ngaphandle ezama landile ukuya kwiintsuku ezingamashumi amathathu.

abanxibe wabonakala Indlela yokugqibela xa kwinkqubo wokwenziwa lenses waqalisa ukusebenzisa igesi ngqongqo izinto akubonakali kunye abicah hydrogel. Ukuba zibe kumgangatho ophezulu oksijini permeability.

Xa imo elide kwaye rhoqo unxibe iilensi replacement contact rhoqo ezicwangcisiweyo. Iindidi ezicwangcisiweyo lens indawo luphawulwa amaxesha yonke imihla kunye neemeko ngeemeko.

lens contact izithambiso

lens zoqhagamshelwano iinjongo ezizodwa

lens Scleral ezisetyenziswa kwiimeko ezinqabileyo xa ogulayo imilo mgaqweni le inwebu, cider "iliso owomileyo", ngaphambili wasiwa keratoplasty njalo njalo. Kulo mzekelo, isithuba emva ilens kwenzeka, nto leyo izaliswe ngolwelo iinyembezi. Le fomu iveliswa ngamnye ngamnye kwaye yahlulwe corneoscleral, poluskleralny, kunye miniskleralnye scleral.

lens Orthokeratology contact kwahluka iindleko eziphezulu, ukuntsonkotha ukhetho kunye elintsonkothe kunye nemfuneko mphandle kwenwebu (izixhobo ezizodwa). Olu hlobo yenzelwe ukulungiswa ukubona ukuya diopters ezintandathu, kwaye myopic astigmatism ukuya kwi 1,75 diopters. Iimbaleki Fit, abantu abasebenza kwiindawo ezinothuli njalo-njalo.

lens contact Hybrid asetyenziswa kwiimeko apho umguli kufuna uhlobo nzima, kodwa isici langoku. Okwangoku, ukuba nalo lwabonisa ukuba uqeqesho astigmatism kunye iqondo eliphezulu keratoconus.

Indlela ukukhetha?

ubuchwepheshe bale mihla ukuvumela ukwenza iintlobo ezintsha lenses contact. Yintoni ukucebisa ngcono zamehlo kuphela. It uwugcinayo iinkqubo eziyimfuneko kwaye ichaza i parameters eziphembelela ukukhethwa lens. Ugqirha wabhala ukuba liyeza, kwaye zisekelwe phezu yempilo yakho kwaye udinga ukuba usebenzise iintlobo ezininzi lenses contact.

Ngexesha lovavanyo defined parameters ezifana acuity zokubonwayo iliso, refraction, indawo yokuhlala nganye kunye imo fundus, nezinyuko nokumila inwebu, njalo-njalo.
