Lens zokudibana ngenyanga - kokona kulungileyo? Indlela ukunxiba iilensi zoqhagamshelwano inyanga?

Umthamo ephambili yolwazi evela ehlabathini ngaphandle (ngaphezu kwama-80%), iza kuthi esebenzisa ngamehlo. Mbono, enika iliso ebantwini, uvumela ingqondo ukuhlola zonke iimpawu into - ububanzi, ubungakanani, umbala. ukungaboni, sinokuthi, kubi kakhulu umgangatho wobomi.

Kude kube kamva nje, kuphela ukhetho (hayi ngotyando) ukuphucula umbono wabo iindondo. Namhlanje ophthalmologists kungayekwa iziguli zabo ukuba masiyeke sixhobo enombala egameni ezintsha ezifana ilens (inyanga 1, ikota, iiveki ezi-2, usuku - elininzi yokwahluka).

Ukuqeshwa lens kunye nezinto ukuba imveliso zabo

Kuxhomekeka neenjongo zamehlo emva kokuba uhlolo ngenyameko kunika ukhetho ilungileyo isigulane ngasinye. Ukuba umntu ufuna nje ukuba nomtsalane, jonga olwahluke, ngoko ke kufuneka entle lenses bebala. Inyanga, iinyanga ezi-3, ibe imini - ukutshintsha inkangeleko okanye wenze incasa ethile ukuya umfanekiso ungaba ngoku phantse wonke umntu.

Ukuba isigulane ukubandezeleka ukusuka ukubona okanye hyperopia kwaye ufuna ukuphelisa le ezingalunganga okuqonda ezibonwayo, ugqibelele ukuba sihlandlo - ungqukuva okanye lenses aspherical. umfanekiso Quality First ezenza yesibini obuphantsi kancinane, apho amandla woqondo efanayo kuwo onke amacandelo. Kuba abantu abagulela ukubona kunye hyperopia sesona sigqibo kakhulu kunene.

Ukubona kwaye hyperopia, astigmatism sikhatshwe (waphula sokubumba okanye lens inwebu), zilungiswe lenses contact toric. Unokuphila ixesha elide kangakanani unxibe lenses? A ngenyanga babele, iiveki ezi-2 okanye elinye ixesha elithile - kuya kuba ukusombulula zamehlo okunyangayo.

Ukongeza, market zonyango mihla ezinako ukufundisa izigulane kunye nezixhobo nasekubalungiseni presbyopia (phambi xhego). Kakuhle eli ingxaki siyifumana mgaqweni iliso refraction apho umntu akakwazi ukufunda itekisi ebhaliweyo print encinane, okanye ukuqwalasela naziphi na izinto ezincinci ezikufutshane. Ezingunobangela anokubakho izifo - ukunciphisa luthambe lens, ukutshintsha ugobile wayo, ukuba buthathaka esihlunwini ciliary, elawula ingqalelo.

Materials zokwakha lens (qho ngenyanga okanye naliphi na ixesha), - yinto hydrogel okanye abicah hydrogel. Ukubunjwa kwesibini ibe nomtsalane kubathengi iimpawu engcono "siphefumle", akunyanzelekanga ukuba loo moistening olunzulu, njengokuba hydrogel. Ngenxa yoko, kunye ilens zoqhagamshelwano esebenzisa izigulane abicah hydrogel baziva bekhululekile ngakumbi.

sokuquqa replacement, iindlela lens wear kunokwenzeka

Eli gama libhekisela amaza ukutshintshwa elona xesha lininzi izixhobo ulungiso ixesha enxibe ngokwemilinganiselo yakowayo. Emva kweli xesha iilensi kufuneka kufakwe ezintsha. Ngokwale parameter, ukuba kwahlulwa ibe:

• lenses ngosuku olunye-zonakele,
• abo ukuba ukuthwala iiveki 1 ukuya 2
• lens contact inyanga (musa ukususa, ukuba ingasetyenziswa ukuya kwiintsuku ezingama-30)
• Kukho kwakhona "ngokukhanya" banxibe eyandisiweyo: ukususela kwiinyanga ezi-3 ukuya kwiinyanga ezintandathu, kwaye lens emveli enokusetyenziswa kunyaka 1.

Iinkcukacha lens endamkhonzayo kwiinyanga ezi-6 ukuya kwele-12, zipakishwe zaphatha ezizodwa.

Ukuze utshintsho rhoqo ngakumbi, badla ezitransparenti kumadyunguza.

Ngokunxiba indlela iqulathe kwexesha ubuninzi bexesha apho ayisuseki iimali ukwenzela ukulungiswa umbono. Ngokomzekelo, elinye iqela lens enzelwe ukusetyenziswa emini (banxibe kusasa, wazisusa ebusuku). Elesibini ibandakanya iindlela elide (Dress for ngeveki yaye iya ndibawisele kuba ubusuku). indlela Flexible wokufaka kubandakanya ukusetyenziswa kweentsuku 1-2 (musa ukususa). ukusetyenziswa rhoqo - oku xa ilens omiselwe inyanga. Ngaphandle kokususa, ukuba zinganxitywa kangangeentsuku ezingama-30. Noko ke, oku kunokwenzeka kuphela xa usebenzisa iintlobo ezithile iimodeli hydrogel abicah zisebenza kubo kuvunyelwa kuphela emva kothetha-thethwano zamehlo.

contact nomoya lens kuthetha

Iinkcukacha lens ezininzi iimpawu ezininzi ezahlukahlukeneyo. Phakathi kwabo bonke abanye diphu wabenzi contact lens onombhalo DK / t. DK Libonisa ioksijini permeability, t - ubukhulu lens kwindawo esembindini. Umlinganiselo ezi iparameters omnye kuthiwa 'ngumlingani ka oksijini transmittance. Kuba hydrogels, eli nani iiyunithi 20-40, ngelilixa abicah hydrogel oko ekungabonini ukusuka units-70 ukuya 170. Ngoko ke, lo elilawulayo kuthetha yenziwe abicah hydrogel, oko kubizwa ngokuba "Amehlo ephefumlayo" (nyanga, ikota, iiveki ezimbini okanye ngenye imini - Akukhathaliseki).

Oksijini ezinjalo iindlela ukulungiswa uthwala icandelo abicah, abathi isizathu zingathathwa njenge uhlobo pump abicah. Umxholo engamanzi lens ezinjalo akuthethi zidlala indima ebalulekileyo efana hydrogel elula, apho umyinge wamanzi kuxhomekeke permeability oxygen (amanzi - permeability ngaphezulu). Ngoko ke, xa esenza isigqibo (ukuba ilens ekhethiweyo kwi inyanga): "? Kukuphi na okulunge ngakumbi - lo hydrogel okanye abicah hydrogel" kuqala kufuneka sinikwe yokugqibela.

Izinto eziluncedo lens replacement ngenyanga

Lens ngenyanga (kokona kulungileyo - ukuxoxwa ngezantsi) ebezifunwa kakhulu phakathi kwabathengi. Izinto eziluncedo zezi mali ukwenzela ulungiso yombono phambi onobuhle iindlela ezahlukeneyo benxibe ezi zinto zilandelayo:

- ubude ukuguga, ethi idibanise ogqibeleleyo lula kunye namaxabiso;

- lens contact zenziwa inyanga enye kuluhlu olubanzi amandla enombala (ukusuka + 6.0 ukuya - 12.0 diopters) ekuvumela ukuba agubungele iqela elikhulu labathengi;

- kuthetha zenziwa ezineempawu ezahlukeneyo kunye neempawu, "nomoya", moisturizers, xa zaneleyo ukufuma inwebu nokonyuka biocompatibility, kuba ukusetyenziswa kwiimeko ekukhanyeni low, kunye yintlenga ephantsi ukwakheka, etc;..

- kuphuhliswa lens ezizodwa ngenyanga 1 kwabo abagulela astigmatism (ezininzi);

- abathengi banikwe ithinti kwaye itshintsha umbala (umbala) lens inyanga, leyo isenokuba kunye diopters, kwaye yakhelwe abantu abane umbono yesiqhelo (zero).

Ukusetyenziswa lenses (zenyanga)

Apha kuyimfuneko ukuba siqwalasele iindlela ezimbini. Imvelaphi - lens kunye imo wear ngemihla. Oku kuthetha ukuba kuyimfuneko ukuba kutolwe ebusuku ze ukugcine isisombululo ekhethekileyo. Ebudeni ngobusuku ebuthongweni uya kuphumla amehlo kunye lens ukuba desensitised ngokwaneleyo, kuya kuba unyango ezizodwa (kweentsholongwane) kunye msulwa iidipozithi ezahlukeneyo okongezeleke emini. lens ezinjalo iirivyu ngenyanga ezincomekayo kakhulu, kodwa kufuneka ukhumbule ukuba isisombululo ezizodwa izikhongozeli zokugcina - kuyimfuneko, ukuba anayenza ngokungqongqo kukho ingozi yomonakalo kungcoliseko imveliso komhlaba. Ngenxa yoko, kukho iinkqubo yokukrala esweni.

Indlela ukunxiba iilensi (inyanga - ixesha eqhelekileyo yokuqeshwa), ukuba ziza kuzinziswa okanye indlela oluqhubekayo ukusebenzisa? Kwakhona unalo bokuqonda yayo. iindlela ezifana nokuqondisa umbono ukujolisa ebusuku, kodwa hayi zonke iimodeli nga zinganxitywa ngokuqhubekayo iintsuku ezingama-30. Abanye abenzi ephendula umbuzo malunga indlela wesinxibo lens inyanga, ngendlela yokuba zinganxitywa iintsuku ezi-6. Ngobunye ubusuku Bamisa spetsrastvor nokucoca. Ke iliso ngeli xesha waphefumla.

Nangona kunjalo, ubugcisa bale mihla abanjalo ukuba kuyenzeka ukuphuhlisa loo lens ezinokuthi zinxitywe kulo nyanga. Emva kweli xesha, ukuba siphoswa nje kude, ngokubuyisela nabantu abatsha. Njengezibonelo enjalo nokuba ufuna isisombululo okhethekileyo. Phakathi iimveliso kakhulu zithandwa namhlanje zezi zilandelayo: Air Optix Night & Day, PureVision, PureVision 2 HD.

Ukuze ufumane inkcazelo malunga indlela wesinxibo lens inyanga ngaphandle kokususa ebusuku, ngokuqhelekileyo iindawo umenzi kumqulu.

Kwaye ngoku makhe sithethe ngayo iimveliso kaie ezifunwa kakhulu.

Ukukhokela lens yenzelwe ukuba isetyenziswe ngexesha ngenyanga (kuphela emini)

Kukho ikho into lens-iinkokheli le nyanga. Kukuphi na okulunge ngakumbi? iimveliso imfuno High umsebenzisi ebizwa MaximaSiHyPlus. Kuzo zonke ezahlukeneyo ezikhoyo, eyenzelwe replacement ngenyanga kunye nokususwa ebusuku, ezi mveliso - ezinye best. Le nkcazelo ukusuka apho kwenziwe, - abicah hydrogel sizukulwana yokugqibela. xa belele Good, inani eliphezulu oksijini transmittance, ukumelana bekelelo nokubonelela ngeemeko bekhululekile biocompatibility amehlo.

Olunye uhlobo lwe lenses, leyo ke imfuno yabantu - into PureVision 2 HD. Kuzo zonke namhlanje eyenziweyo ukuba zezona noxhamla ubuncwane. oksijini High transmittance lomlingani (uhlobo lwe "lens komoya 'inyanga), wesinxibo nabo iveki ngaphandle kokususa. PureVision 2 HD inika imbono ecacileyo ezibonwayo, nkqu iimeko zokukhanya, kwaye amehlo andimvumeli ebubini.

inqanaba elimangalisayo wentuthuzelo zinika umntu "Acuvue" lens (inyanga). izinto -art kusetyenziswa ukuvelisa kubo. Ecacileyo picture xa usebenza kwi khompyutha, ubukele umabonwakude, xa kwigumbi umoya owomileyo, elihle intuthuzelo breathability isiqinisekiso kunye nokhuseleko lwalo.

Imifuziselo best ukuguga eyandisiweyo

Phakathi yemifanekiso, yenzelwe ukusetyenziswa rhoqo, kukho iinkokheli - lens contact inyanga. Kukuphi na okulunge ngakumbi? imfuno Wide ke imveliso Air Optix Night & Day Aqua. Le nkcazelo olusetyenziswa wokwenziwa kwawo, - abicah hydrogel. Inqanaba ngokupheleleyo isiqulatho sokufuma kunye nezinga isicatshulwa air eliphezulu ukunika amehlo intuthuzelo ngexesha lonke ixesha ukuguga.

lenses Biofifnity (CooperVision) ikwayilelwe ukuba kunxitywa ngenyanga (kuphela emini) okanye ukusetyenziswa rhoqo iiveki ezi-2. Abicah hydrogel, ukusuka apho kwenziwe, wokusebenza vozduhopropuskaemosti ilungileyo ukunyakama, ukuqinisekisa ukhuseleko iliso kunye nentuthuzelo ngexesha lonke ixesha yokusebenza.

lenses "Acuvue"

Ezinye ethandwa kwimarike lonyango kuthetha ukulungiswa mbono ayikho intsumpa - ". Acuvue Oasis" isekelwe A inyanga enye babe ngokubanzi, ayenzelwanga. Ithekhnoloji unique, ezo zenziwe lens kudibanisa imiba emibini ebalulekileyo ekukhuseleni iliso ukusuka ukudumba: amafutha kunye ngokuqhubekayo oxygen kufumaneka bantu.

Ngoko ke akukho mfihlakalo ukuba namhlanje abaninzi syndrome amehlo "owomileyo", oonobangela apho - .. Namashishini nokufuma ephantsi, ehleli ixesha elide kwi-computer, phambi TV, njl Ngaphambili, nomonde zamehlo sisifo onjalo ebengayi kuba nako ukukhetha lenses contact. lo mbuzo ngokulula isonjululwe namhlanje. Lens "Acuvue" (inyanga, ukuba ayenzelwanga, nkqu ngaphandle replacement, kodwa iiveki ezimbini - uvunyelwe) zenziwa kunye izithako amafutha ezizodwa gqolo ezalise ukufuma iliso. Nangona kukho abathengi abanxibe ezi lens inyanga, qiniseka ukuba ukususa ebusuku. Ekupheleni kweeveki ezi-4, imveliso kungaba kancane zinodaka (kwaye uhlale ngaphaya).

Izigulane ezininzi ziphakathi ucinga ingenankathazo imihla lenses 1 Usuku ACUVUE TruEye. Isetyenziswa ukuba ukwenziwa abicah hydrogel (hydrogel ezisetyenziswa ngokuqhelekileyo ngosuku). Le oksijini permeability lomfowunelwa kuthetha uqeqesho umbono 100%. Ezi lens bekhululekile ukuze ukuvumela umntu ukuba akhohlwe 'ngobukho bazo. "

The degree of oksijini permeability yezi ndlela lens zoqhagamshelwano kude lidlula oko ingqalelo eqhelekileyo ukuba wonke umntu. Lens "Acuvue Oasis" (nyanga ifuna iiseti ezimbini) babonelelwa UV-lokucoca ulwelo kwiklasi yokuqala, olukhusela retina kunye ilens of radiation B (phantse 100%) ne-A reyi (ku-96%).

"Acuvue Oasis" (iiveki ezimbini), okanye naziphi na iilenisi zoqhagamshelwano ngenyanga (leyo ngcono - kuxhomekeke kubathengi kunye ugqirha), qiniseka ukuba uthabathe nawe xa uhamba ekhefini.

lens ngekota

lens ngekota (iinyanga ezi-3) buyekezwa ophthalmologists kunye nabathengi musa cinga ngeyona ndlela contact lens. Izixhobo wear eyandisiweyo efana kufuneka aphathwe ngokufanelekileyo ingqalelo (oku ngenyameko ngenyameko kakhulu). Namhlanje, abantu banoxanduva bakhetha lens kunye ubomi inkonzo (njenge mihla ngakumbi kwaye bekhululekile, ezenziwe ngezinto eziphambili).

Amarhamente kwiindlela ulungiso yokonakala ixesha elide ukuncoma imveliso Precision UV (CIBA Vision Corp). Izinto esetyenziselwa imveliso yabo (hydrogel), uvimba ukuya kwi 91% ye-UV radiation iliso yingozi. lens contact ezinjalo - ukhetho okuhle abo phila ngendlela ngokukhawuleza yobomi akusoloko Awukwazi ukususa icebo.

Uluvo kwabathengi kunye neengcali, Ophthalmologists

Ngoko ke, ngaba kunokwenzeka ukuba aze anxibe iilensi inyanga ngaphandle kokuba ukususa? Izimvo ophthalmologists malunga oku ezininzi ezintle. Ukuba ulungiso kuthetha unyule zeengcali kwi imeko ngeliso nomonde, ukuba zinganxitywa iintsuku ezingama-30, kodwa kufuneka ukhumbule umhla replacement okucwangcisiweyo kwaye unike amehlo akho luphumlo ubusuku obunye ubuncinane. Ngentsasa elandelayo, uyakwazi ngokukhuselekileyo nxiba kwisethi entsha lenses ukusetyenziswa ixesha elide. Nakuba kunjalo, ukuba ngaba isigulane kakubi, ilens kufuneka zisuswe nangoko aze adibane specialist.

Ke ukuba abathengi, inani kubantu ziyintoni kuthetha kakhulu eyiyo ulungiso mbono zoqhagamshelwano. Lens (nayiphi - namhla veki nganye, wear ngenyanga, ngekota, njl ...) Ngaba phantse ingabonakali ngaphandle kunye nombono iba libukhali ngaphezu xa usebenzisa iindondo. Ukuze ubone icala, "i bespectacled" uye ukuguqula intloko yakhe, indoda kunye squint lens ngokwaneleyo. Ngokungafaniyo iindondo lens angaweli ngexesha iintshukumo ngesiquphe yaye musa ukubila phantsi utshintsho lobushushu kokugquma le ngequbuliso. Yaye eneneni indoda lens ekhoyo nawuphi na umdlalo, ezolonwabo njalo njalo. N.

Bawo, Kakade ke, kufuneka indawo yabo. Abathengi bathi (kunye ophthalmologists ukuqinisekisa oku) ukuba lenses abanyuliweyo ngokungachanekanga, ungaqalisa kwinwebu amehlo kwaye ngamanye amaxesha mbono ukuze zimbi. Ukongeza, ipesenti encinane yabantu le alikhazimli ethe kakhulu. Ezi kubathengi nje abanakunxiba lenses, kwaye kwafuneka ukuba uma- iindondo. Noko ke, le sifo kakhulu inqabile. Ubuninzi babantu abasebenzisa lenses, uyakholiswa kakhulu iziphumo kwi-sicelo.

Kulungile, loo nto ngawo onke. Ekugqibeleni, sikhumbula ukuba neobohodimost endaweni iilensi iindondo contact ebesilindelwe, eyona nto ibalulekileyo - ukuba babuyele oyingcaphephe elungileyo, zamehlo, ngubani oza kuhlola iingenelo neengozi anike iingcebiso ezifanelekileyo.
