Imininingwane lens for ngenyanga - okuyinto engcono? Indlela ukugqoka contact lens for ngenyanga?

Umqulu ezinkulu zolwazi nezwe (kuka 80%) esisithola emehlweni. Umbono, esinikela ehlweni lomuntu, okuvumela ingqondo ukuba ahlaziye kahle zonke izici into - ububanzi, usayizi, umbala. angaboni kahle, singasho, kakhulu siba sibi izinga lempilo.

Kuze kube muva nje, VO (hhayi kuhlinzwa) ukuthuthukisa umbono wabo babe izibuko. Namuhla bamehlo ngokuya angayinikeza iziguli zabo ukulahla lo mshini optical esivuna ezintsha ezifana lens (inyanga engu-1, ingxenye yesine, amasonto ama-2, ngoba ngosuku - eziningi ezahlukeneyo).

Ukuqokwa amalensi zokwakha umkhiqizo wabo

Kuye yezinhloso ophthalmologist emva ukuhlolwa ngokucophelela anikela ukhetho kangcono enganeni ngayinye nesineke ngabanye. Uma umuntu efuna nje likhanga, bheka ehlukile, ke kufanele kube okuhle lens anombala. Ukuze inyanga, izinyanga 3, ngoba ngosuku - ukushintsha ukubukeka noma ukwenza ukunambitheka ezithile esithombeni can manje cishe wonke umuntu.

Uma isiguli uhlushwa myopia noma hyperopia futhi ufuna ukuqeda lezi yokuntula okuqonda sibonwa, ephelele for the senzakalo - eyindilinga noma lens aspherical. Okokuqala Quality isithombe ukwakha yesibili kancane eliphansi, lapho amandla optical kuyafana kuzo zonke izingxenye. Ukuze labo abaphethwe myopia futhi hyperopia kuyinto isinqumo esifanele kakhulu.

Myopia futhi hyperopia, astigmatism ephelezelwa (ukwephula isikhunta noma kuyi-lens cornea), kungase kushintshwe contact lens toric. Ungaphila isikhathi eside kangakanani ukugqoka lens? Esikhathini esingangenyanga oyinikeza kubo, amasonto 2 noma kwenye inkathi yesikhathi - kuzoba ukuxazulula ophthalmologist ekwelapheni.

Ngaphezu kwalokho, imakethe yezokwelapha zesimanje banganikeza iziguli namathuluzi kokulungisa presbyopia (emehlweni khehla). Ingqikithi inkinga itholakala anomalies iso kwalungiswa izinkunga zokubona lapho umuntu akakwazi ukufunda ebhalwe ngamagama amancane, noma cabanga yiziphi izinto ezincane uhla close. Izimbangela Cishe iningi isifo - ukunciphisa kuyaqina lens, ukushintsha ugobile yayo, buthakathaka imisipha ciliary, olawula i-focus.

Izinto yokwakha ama-contact lens (nyangazonke noma iyiphi enye inkathi), - kuba hydrogel noma abicah hydrogel. Eyesibili Ukwakheka has a ngaphezulu kukhanga abathengi izimfanelo kangcono "ukuphefumula", akudingi enjalo moistening olunzulu, njengoba hydrogel. Ngenxa yalokho, ne-lens contact esebenzisa iziguli abicah hydrogel bazizwa bekhululeke kakhudlwana.

esikhundleni imvamisa, izindlela okungenzeka lens bafake

Leli gama libhekisela ukuvama esikhundleni isikhathi esiphezulu isikhathi egqoke namathuluzi wokulungisa Kunconywa ngumkhiqizi. Ngemuva kwalesi sikhathi lens kufanele kuthathelwe indawo emisha. Ngokusho lokhu ipharamitha, zingase zihlukaniswe zibe:

• wosuku olulodwa contact lens kukhona bakhathale,
• yibo okuthwala 1 2 amaviki
• contact lens for ngenyanga (ungasusi, angasetshenziswa kufikela kuzinsuku ezingu-30)
• Kukhona "yokukhanya" bafake enwetshiwe: kusuka 3 izinyanga izinyanga eziyisithupha, kanye lens bendabuko engasetshenziswa unyaka 1.

Contact lens ukuthi ukukhonza isikhathi esisuka 6 izinyanga ezingu-12, igcwele e flasks ekhethekile.

Ushintsho njalo, bavame Agcwele amabhamuza.

Ngu egqoke imodi siqukethe esiphezulu inkathi yokuvumela izimali ngenxa yokulungiswa umbono ayikwazi ukususwa. Ngokwesibonelo, elinye iqembu lama-lens yenzelwe ukusetshenziswa emini (bagqoke up ekuseni isuswe ebusuku). I sesibili kuhilela indlela isikhathi eside (Gqoka ngesonto futhi ngeke ukhokhiswe ebusuku). Imodi Nezimo egqoke kuhilela ukusetshenziswa izinsuku 1-2 (ungasusi) ka. ukusetshenziswa okuqhubekayo - lena lapho lens ezinqunyiwe ngenyanga. Ngaphandle kokukhipha, bangakwazi igqoke izinsuku ezingu-30. Nokho, lokhu kungenzeka kuphela uma usebenzisa uhlobo oluthile abicah hydrogel onobuhle futhi uzisebenzise kuvumeleke ngemuva kokuxoxisana ophthalmologist.

contact esiwuhogelayo lens izindlela

Contact lens Ziningi izici ezihlukahlukene kakhulu. Phakathi kwabo bonke abanye asemaphaketheni yanoma yimuphi umakhi contact lens libhaliwe Dk / t. Dk lisho oxygen permeability, t - ukushuba lens at endaweni eyodwa. Isilinganiso lezi nemingcele komunye nomunye kubizwa ngokuthi Coefficient umoya-mpilo transmittance. Ukuze hydrogels bangamaphesenti amayunithi 20-40, isikhathi abicah hydrogel kungaba isukela amayunithi 70 170. Ngakho-ke, i-lens contact kusho eyenziwe abicah hydrogel, kusengathiwa "lenses okuphefumulayo" (inyanga, ikota, emasontweni amabili noma usuku olulodwa - akunandaba).

Oxygen e ezifana ukulungiswa izindlela ithwala abicah ingxenye, okuyinto ngesizathu esihle kungase kubhekwe njengokwelapha uhlobo abicah futha. okuqukethwe liquid lens esinjalo asisho ukuthi akudingeki zidlala indima ebalulekile ezifana hydrogel elula, lapho inani lamanzi incike permeability mpilo (amanzi ngaphezulu - permeability ngaphezulu). Ngakho-ke, lapho enza isinqumo ngokuphathelene (uma lens olukhethiwe ngenyanga): "? Yikuphi okungcono - the hydrogel noma abicah hydrogel" ntandokazi kufanele inikwe lakamuva.

Izinzuzo nyangazonke esikhundleni lens

Lenses ngoba ngenyanga (okuyinto engcono - ukuba kuchazwe lapha ngentasi) bayindlala kakhulu phakathi abathengi. Izinzuzo lezi zimali i-ukulungiswa umbono phambi onobuhle izindlela ezahlukene egqoke lokhu okulandelayo:

- isikhathi zokuguga, inhlanganisela ephelele lula kanye namanani;

- contact lens zenziwa inyanga eyodwa ngendlela ezahlukene amandla optical (kusuka + 6.0 kuya - 12.0 diopters) okuvumela ukuba amboze iqembu elikhulu abathengi;

- izindlela zenziwa nezakhi ezihlukene futhi izakhiwo, "esiwuhogelayo", moisturizers, lapho enganele umswakama cornea ne biocompatibility yanda, ukusetshenziswa ezimweni ongaphakeme ukukhanya, ne inzika ongaphakeme ekwakhekeni, njll;..

- athuthukile lens ezikhethekile inyanga engu-1 kulabo abaphethwe astigmatism (multifocal);

- abathengi uphiwa tint nokushintsha umbala (umbala) lens inyanga yonke, okungaba noma nge diopters, futhi yakhelwe abantu obona kahle (zero).

Ukusetshenziswa contact lens (ngenyanga)

Lapha kubalulekile ukuba sicabangele ezimbili. Umsuka - lens nge bafake imodi nsuku zonke. Lokhu kusho kubalulekile ukudubula ebusuku kanye nokugcina in isixazululo ekhethekile. Ebusuku bango-ubuthongo uyophumula emehlweni kanye lens ngokwanele wetted, kuyoba ukwelashwa okukhethekile (magciwane) kanye msulwa ezifakwa ahlukahlukene ekuthole emini. lens ezinjalo Izibuyekezo ngenyanga omuhle kakhulu, kodwa kumelwe sikhumbule ukuthi isixazululo akhethekile iziqukathi yokugcina - ke kungokudingekayo, uma kungekhona ngokuqinile waphawula kunobungozi lokulimala ukungcola umkhiqizo ebusweni. Ngenxa yalokho, zikhona izinqubo ukuvuvukala esweni.

Indlela agqoke lens (ngoba ngenyanga - kwesikhathi esezingeni aphoyintimenti), uma wasekela noma imodi eqhubekayo ukuyisebenzisa? It Ubuye umehluko wemisindo nemiqondo yamagama yayo. Izindlela ezinjalo ngoba umbono isilungiso ukudubula ebusuku, kodwa hhayi wonke amamodeli kungenziwa igqoke ngokuqhubekayo izinsuku ezingu-30. Abanye abakhiqizi ephendula umbuzo mayelana kangakanani ungakwazi ukugqoka lens for ngenyanga, ngendlela ukuthi kungenziwa igqoke izinsuku 6. Kwabe sekuthi ngobunye ubusuku abakufaka spetsrastvor ukuze bahlanze. Futhi iso phakathi nalesi sikhathi waphumula.

Nokho, ubuchwepheshe besimanje kangangokuthi kwakunokwenzeka ukuthuthukisa kanye lens enjalo okungatholakala igqoke kulo lonke ngenyanga. Emva kwalesi sikhathi, basuke nje ziyalahlwa, esikhundleni emisha. Ukuze onobuhle enjalo angase angasheshi ngisho kudingeka isixazululo ekhethekile. Phakathi imikhiqizo ethandwa kakhulu namuhla yilezi ezilandelayo: Air Optix Night & Day, PureVision, PureVision 2 HD.

Ukuze uthole ulwazi mayelana kangakanani ungakwazi ukugqoka lens for ngenyanga ngaphandle kokukhipha nabo ebusuku, ngokuvamile izindawo umakhi on the isembozo.

Futhi manje ake sixoxe imikhiqizo kaie anegunya funa.

Oholela lens yenzelwe ukusetshenziswa enyangeni (emini kuphela)

Kukhona into okuthiwa lens-abaholi ngenyanga. Yikuphi okungcono? umthengi High imikhiqizo funa ngokuthi MaximaSiHyPlus. Kuzo zonke ezahlukeneyo ekhona, eyenzelwe esikhundleni ngenyanga ne ukususwa ebusuku, mikhiqizo - ezinye zezindawo ezingcono kakhulu. Indaba okuvela ngazo zenziwa, - abicah hydrogel isizukulwane eledlule. ogelezayo nokumanzisa Good, Coefficient okusezingeni eliphezulu le-oxygen transmittance, ukumelana imali kanye nokuhlinzeka biocompatibility iso izimo ukhululekile.

Enye imodeli contact lens, okuyinto bayindlala sabantu - kuyinto PureVision 2 HD. Kuzo zonke ekhiqizwa namuhla zingabantu obucayi kakhulu. umoya-mpilo High transmittance Coefficient (uhlobo "lens esiwuhogelayo" ngoba ngenyanga), ungakwazi sizigqoke ngeviki ngaphandle kokukhipha. PureVision 2 HD inikeza bezibona ngokucacile ezibukwayo, ngisho nangaphansi kwezimo ezimbi zokukhanya, futhi amehlo musa uhlushwa ukungakhululeki.

ezingeni esihle kakhulu senduduzo ukunikeza umuntu "Acuvue" lens (ngoba ngenyanga). izinto -art esetshenziswa ukwenza kubo. Sula isithombe ngenkathi usebenza kuma-computer, i-TV, uma usegumbini nge emoyeni elomile, kakhulu breathability isiqinisekiso ethokomele nephephile esweni.

Leyo mikhumbi kangcono bafake enwetshiwe

Phakathi amamodeli, yenzelwe ukusetshenziswa okuqhubekayo, kukhona abaholi - contact lens inyanga. Yikuphi okungcono? funa Wide ingumkhiqizo Air Optix Night & Day Aqua. Indaba okuyinto lisetshenziswa womshini zabo, - abicah hydrogel. Izinga kahle umswakama okuqukethwe nomoya okusezingeni eliphezulu ndima izinga ukunikeza induduzo amehlo phakathi nayo yonke inkathi zokuguga.

Contact lens Biofifnity (CooperVision) Futhi wenzelwe ukunikeza izingane igqoke ngoba ngenyanga (ngesikhathi kuphela ngosuku) noma ukusetshenziswa okuqhubekayo amasonto ama-2. Silicone hydrogel, kusukela lapho kwenziwa, has best ukusebenza vozduhopropuskaemosti futhi umswakama, ukuqinisekisa ukuphepha iso nenduduzo phakathi nayo yonke inkathi wokusebenza.

Contact lens "Acuvue"

Ezinye ethandwa kakhulu emakethe wezokwelapha kusho umbono ukulungiswa akuyona surgically - ". Acuvue Oasis" lens Esikhathini esingangenyanga ababekuso jikelele, it is hhayi yakhelwe. Ubuchwepheshe esiyingqayizivele, okuyinto eyenziwe lens ihlanganisa izici ezimbili ezibalulekile ukuvikela iso kusukela ukuvuvukala: asenze futhi okuqhubekayo-mpilo saturation.

Akusiyo imfihlo ukuthi namuhla abaningi bebhekana syndrome kwamehlo "ezomile", izimbangela zazo - .. Izakhiwo kanye nomswakama ongaphakeme, eside ihlezi ikhompyutha, phambi-TV, njll Ngaphambili, nesineke ophthalmologist ngesifo ezinjalo ngeke bakwazi ukucosha contact lens. umbuzo isixazululekile kalula namuhla. Lens "Acuvue" (I-ngenyanga, azihloselwe, ngisho ngaphandle esikhundleni, kodwa amasonto amabili - ke kuvunyelwe) zenziwa nge ekhethekile amafutha izithako ngokuqhubekayo igcwalisa umswakama iso. Nakuba zikhona amakhasimende ukugqoka lezi lens for ngenyanga, qiniseka ukususa ebusuku. Lwathi luphela amaviki 4, umkhiqizo kungaba kancane ezinodaka (futhi angahlala ngale).

Iziguli eziningi kukhona phakathi ukhululekile kakhulu bacabanga nsuku zonke contact lens 1 Usuku ACUVUE TruEye. Isetshenziselwa womshini abicah hydrogel (hydrogel ngokuvamile esetshenziselwa usuku). I permeability-mpilo loxhumana naye kusho umbono ukulungiswa ngo-100%. Lezi lens ukhululekile ukuze uvumele umuntu ukuba akhohlwe "ngokuba khona kwabo."

Izinga lomoya-mpilo permeability yalezi esebenzisa contact lens kude kakhulu lapho kubhekwa evamile wabo bonke abanye abantu. Lenses "Acuvue Oasis" (ngenyanga kudinga amasethi okungenani amabili) anikezwa nge UV Elihehayo ekilasini lokuqala, esivikela retina kanye lens B emisebeni ye (cishe u-100%) no-ray (96%).

"Acuvue Oasis" (amasonto amabili), noma ama-contact lens for ngenyanga (okuyinto engcono - kukuwe umthengi futhi udokotela), qiniseka ukuba bathathe nawe lapho uya eholidini.

lens wekota

lens Quarterly (izinyanga 3) libuyekeza bamehlo futhi abathengi ungacabangi engcono inketho contact lens. Amathuluzi anjalo bafake enwetshiwe kufanele aphathwe ngendlela efanele ukugxila (lena ukunakekelwa niqaphelisise). Namuhla, abantu ngokuya uncamela lens ngokuphila service emifushane (njengoba zanamuhla futhi ukhululekile, ezenziwe ngezinto eziphambili).

Amalungu ukuyiqondisa zokukhandleka eside batusa umkhiqizo hle UV (CIBA Vision Corp). I ezazisetshenziselwa ukwenza umkhiqizo wabo (hydrogel), ivimbela kuze kufinyelele 91% of the ayingozi iso emisebe ye-UV. contact lens okunjalo - option best for labo phila ngakhethi indlela okusheshayo ukuphila futhi ngaso sonke isikhathi bakwazi ukususa idivayisi.

Umbono abathengi kanye nezifundiswa, bamehlo

Ngakho, kungenzeka ukuba agqoke futhi ukugqoka lens for ngenyanga ngaphandle kokuthi ususe? Uphenyo bamehlo kulesi sici kweziningi ezinhle. Uma ukulungiswa kusho abakhethiwe onguchwepheshe isimo ngeso nesineke, bangakwazi igqoke izinsuku ezingu-30, kodwa udinga ukukhumbula usuku esikhundleni kuhlelwe futhi unike amehlo akho ukuphumula okungenani eyodwa ubusuku. Ekuseni, ungakwazi abeke ngokuphepha isethi entsha contact lens ukusetshenziswa eside. Nokho, uma isiguli sifuna ungakhululekile, lens kufanele kususwe ngokushesha futhi uthintane onguchwepheshe.

Njengoba abathengi, inani labantu kuyizindlela impela umbono contact ukulungiswa. Lenses (noma iyiphi - usuku masonto onke, bafake nyangazonke, ngonyangantathu, njll ...) Ingabe cishe ingabonakali ngaphandle umbono iba libukhali kakhulu kunalokho uma usebenzisa izibuko. Ukuze ubone ohlangothini, "le bespectacled" has ukuthi ujikise ikhanda lakhe, futhi le ndoda ephethe squint lens ngokwanele. Ngokungafani izibuko lens angawi ngesikhathi ukunyakaza kungazelelwe futhi musa ujuluke ngaphansi noshintsho olusheshayo we lokushisa kuma. Futhi ngempela indoda abanamalensi etholakalayo noma iyiphi, kukhibika nokunye. N.

Nebubi, yebo, futhi libe nendawo yalo. Abathengi ngithi (futhi bamehlo uqinisekise lesi) ukuthi uma ama-contact lens zikhethwa ngokungalungile, ungaqala ukucasuka kwamehlo futhi ngezinye izikhathi umbono kungenzeka zimbi nakakhulu. Ngaphezu kwalokho, idlanzana labantu cornea kuyinto ebucayi kakhulu. Lezi abathengi abanakukwazi ukugqoka contact lens, futhi kwadingeka ukuba ungenza izibuko. Nokho, lokhu syndrome ngempela ezingavamile. Kwenqwaba yabantu abasebenzisa ama-contact lens, ujabula kakhulu ngemiphumela etholakala.

Awu, lokho kumayelana zonke. Ekugcineni, sikhumbula ukuthi uma neobohodimost ukuba esikhundleni lens izibuko contact sekwephuzile, into esemqoka - ukuze ujike omuhle onguchwepheshe, ophthalmologist, ngubani uzohlola ngokucophelela ngobuhle nangobubi bawo bese ukunikeza izincomo ezifanele.
