Iphi ilensi yosuku olulodwa engcono? Imibiko yekhasimende kanye nezeluleko zokwaziswa

Ama-lens othintana nabo abe yingxenye yempilo yethu. Kuwo wonke umhlaba, abantu abangaphezu kwezigidi eziyi-100 bawasebenzisa ukulungisa umbono. Lokhu akumangazi, ngoba ngokungafani nezibuko, azicabangi ububanzi bombukiso, ungalinganisanga umsebenzi womuntu womuntu (angakwazi ngisho ukudlala ezemidlalo) futhi angabonakali. Nge-myopia, i-hyperopia, i-astigmatism nezinye izinto ezibonakalayo, ziyasetshenziswa abantu abaningi.

Muva nje, imiklamo yokuhlobisa ibuye iqale ukugqokwa. Ngosizo lwabo, ungakwazi ukuqinisa noma ukushintsha umbala wemvelo wamehlo futhi uzuze umphumela omangalisayo.

Amalensi oxhumana nawo angashintshwa ngokuphumelelayo ngezingubo zokugqoka. Ukuzinakekela akuthatha isikhathi esiningi. Uma ukhetha le ndlela yokulungiswa kombono, ayikho inkinga ngokusetshenziswa kwezimonyo. Amalensi oxhumana nawo akuvumela ukuba uhambe ngokuphila okusebenzayo kuzo zonke izindlela. Okuhle kakhulu kubagijimi bangolunye usuku lokuxhumana lens (okungcono - cabanga kamuva). Ngabo, ungagqoka isikrini selanga, izibuko ze-3D noma ezinye izinto zokusebenza.

Ukukhethwa kwamalensi

Ukuze ukhethe indlela yokulungiswa kombono, kubalulekile ukubonana nodokotela. Nguye kuphela ongathola imodeli oyidingayo. Udokotela uzongcoma amasampuli akhululekile nakakhulu. Yimaphi ama-lens angcono, usuku olulodwa noma amaviki amabili? Akuyena kuphela oshayela ukhetho lombuzo. Iphi lens day-day eyodwa engcono kakhulu? Sizozama ukuphendula imibuzo ethile, kodwa sixwayisa: ungalibali ukuvakashela ochwepheshe, ungakhethi amamodeli ngokwakho.

Izinhlobo zamalensi oxhumana nabo

Ama-sampuli ahluke kulokho abenziwe khona (kanzima, soft), ngesimo (flat, conical, njll) kanye neminye imingcele.

Ukugxila ngokukhethekile ekukhetheni indlela yokulungiswa kombono kunikezwa ngesikhathi sokushintshwa kwebhangqwana elisetshenzisiwe ngomusha omusha. Izibonelo ezikhona zihlukaniswe zibe izinhlobo eziningana:

1. Usuku olulodwa. Isikhathi sokunconywa sokusetshenziswa singamahora angu-24. Emva kwalokho, i-lens idinga ukushintshwa. Ngosuku olulandelayo azivunyelwe ukusetshenziswa.
2. Ukushintshwa okuhleliwe. Isikhathi sokunconywa sokusetshenziswa singaphezulu kwamasonto amabili. Ebusuku, zifakwa esitsheni esigcwele isisombululo esikhethekile, emva kwalokho singasetshenziswa futhi.
3. Ukushintshwa kwenyanga. Kudinga kabusha emuva kwezinsuku ezingu-30 zokusetshenziswa.
4. Isiko. Ukuphila kwenkonzo kungaphezu kwenyanga (izinyanga ezingu-3-6).

Le parameter ibaluleke kakhulu futhi ithinta ngokuqondile impilo yamehlo.

Kwenzekani ku-lensi enokusetshenziswa isikhathi eside

I-lens njengento yangaphandle, ebusweni beso, kufanele ibe esimweni esiphelele. Lokhu kuphazamisa ubuqotho bayo (ukukhipha ukulimala), ukuhlanzeka (ukuphelelwa amandla okuphelele) nokuntuleka kwebala. Uma kusetshenziswe i-lens ethize, cishe kungenzeka ukwephulwa kwezimo ezingenhla noma ngaphezulu nokubukeka kwezinkinga.

Ngemuva kokusebenzisa i-lens efanayo ngaphezu kwenyanga, amafomu okumboza angabonakali kuso. Ama-proteine namafutha anamathela ebusweni, ashintshe ukukhanya kwe-lens, asebenze njengendlela yokudla enezakhi ezincane ezincane futhi abangele ukusabela kokugula. Yingakho ezinhlobonhlobo ezinjalo kunesidingo sokunakekelwa okwengeziwe (ukwelashwa nge-enzymatic, disinfection). Kumele zihlanzwe kahle nsuku zonke. Izingxenye zezixazululo zingase zibophezele futhi zikhulise lesi simo. Futhi, izinkinga ze-ophthalmologic ziholela ekunciphiseni kwe-hydrophilicity ye-lens kanye nokubonakala kwesisindo emehlweni.

Isiqinisekiso sokunciphisa ngokuphepha nokwanda esikhathini sokusetshenziswa

Ubufakazi buyinto eyancipha ekunciphiseni okubangelwa yizifo ezithathelwanayo kanye nezifo ekuguqulweni kwamalensi wendabuko kuya kumamodeli ngokushintshwa okuhleliwe.

Lo mphumela ubonakala emiphumeleni yezifundo eziningi zezokwelapha. Ukuthola isiqinisekiso sokunciphisa ukuphepha kwamalensi okuxhumana njengesikhathi sokusetshenziswa kwawo kwanda, kwaholela ukwandisa ekukhiqizweni yizinkampani ezibonakalayo zamamodeli kuze kube yizinsuku ezingu-14. Ukusindisa kuma-sampula yendabuko futhi ngeke kusebenze ngenxa yokwanda kwezindleko zeziqukathi, i-disinfectant kanye nezindlela ze-enzymatic.

Ngakho-ke, umbuzo wukuthi ama-lens angcono, usuku olulodwa noma inyanga zonke, impendulo ayinakuqhathaniswa - usuku olulodwa.

Yini ongayenza: ukushintshwa kwamalensi okuhleliwe noma okulahlwa?

Yimaphi ama-lens angcono, usuku olulodwa noma amaviki amabili? Ukuze uphendule lo mbuzo kubalulekile ukuqonda ukuthi umehluko kulawa masampuli akukhona kuphela esikhathini sokusebenzisa imodeli ethile.

Ukuze ulondoloze i-lens izinsuku ezingu-14 esimweni esihle (ubushelelezi, uhlanzekile, ngaphandle kwamadiphozi), udinga ukubheka. Nsuku zonke emva kokukhipha i-lens ngezandla ezihlanzekile, ezomile, zihlanza nge-mucus esisha. Uma usebenzisa izixazululo eziqukethe i-peroxide, fiphaza. Bese ufaka i-lens esitsheni esihlanzekile (for lens ngayinye ihlukile), gcwalisa nesisombululo esisha jikelele.

Ukugcina ilensi yosuku olulodwa esimweni sokusebenza, kufanele uyifake ngezandla ezihlanzekile, ezomile futhi ususe ekupheleni kosuku.

Ukusho ukuthi yimaphi ama-lens angcono (usuku olulodwa noma amaviki amabili) kuwe, udokotela uzokwazi. Futhi okulula kakhulu? Ngokuqinisekile, ilahlwa.

Izici zezinsuku zokuxhumana zosuku olulodwa

Ngamaphi amalense wezinsuku owodwa angcono ukukhetha okwamanje, unganquma ngokubonisana. Njengomthetho, i-oculist iphakamisa izibonelo ezifanele zesiguli esithile. Sizoyiqonda, okudingayo ukuze unake lapho unquma ukuthi yiliphi lensuku elilodwa elihle kakhulu.

Lezi zindlela zombono zingenziwa nge-hydrogel noma i-hydrogel ye-silicone. Lesi samuva sinamuhla futhi sikhiqizwa yinani elincane lezinkampani zokukhiqiza. Impendulo yombuzo, ukuthi amalensi amalanga owodwa angcono kuncike ekubambeni, azofaka inkomishi yokukhetha kumamodeli we-silicone-hydrogel.

I-permeability ye-oksijeni izophinde ibe nobunikazi be-lens eyodwa. Yikuphi okungcono ukukhetha? I-oksijeni eyengeziwe ingena ku-cornea, i-prognosis ihamba kahle. Ngakho-ke, uma unquma ukuthi yiziphi i-lens zosuku olulodwa ezingcono kakhulu, ukukhetha kuzoba nesampula nge-oksijeni ephezulu yokuphelela.

Esinye sezici ezibaluleke kakhulu zama-lens okuxhumana nawo okuqukethwe okungumswakama. Isifiso seziguli ezithile ukusebenzisa i-hydrogel lens ngamagugu aphezulu ale parameter ayiphutha. Lapho ephakeme, iso lime kakhulu. Iphi ilensi yosuku olulodwa engcono ukukhetha kusuka kokuqukethwe komswakama? I-Hydrogel enezinga lokuswakama ngamaphesenti angaba ngu-50, kanye ne-silicone-hydrogel - enomthamo oswakama umswakama.

Ukubuyekeza odokotela neziguli

Ukuqaphela ukuthi kungcono ukusebenzisa ilensi yocingo lunye lunye, ngifuna ukukhetha okuhle kakhulu kubo. Iziguli nodokotela babelana ngemibono yabo. Iphi ilensi yosuku olulodwa engcono? Ukubuyekezwa ezinkundleni eziningi kusikisela lezo noma ezinye izinhlobo zokusetshenziswa. Abaningi babo babumbene kulokhu okulandelayo:

1. Ukuba khona kwamalensi akhethiwe kahle kwenza kube lula ukubona umhlaba ngokugcwele.
2. Amalensi okuxhumana nawo angumkhiqizo wanamuhla futhi ophezulu kakhulu.
3. Ukusebenzisa i-lens ngelinye ilanga kuyisinqumo esihle kakhulu ngokuphila okusebenzayo, basindisa isikhathi esiningi.
4. Ukusetshenziselwa izincomo ezincane akubandakanyi izinkinga kanye nokuphendula okubi.

Futhi, amakhasimende ancoma ama-lens enkampanini "Akuyev" (lo mkhiqizi ubeka phezulu ekulinganisweni kwezinyathelo ezingcono zokuthuthukisa amehlo). Akunakwenzeka ukukhuluma ngenkampani yaseMelika uJohnson & Johnson. Imikhiqizo yabo isakazwa emazweni angaphezu kuka-175 emhlabeni jikelele.

Phakathi kwabakhiqizi baseRashiya kungenzeka ukuba uhlukanise inkampani ethi "Concor" no "Doctor Optik". Bakhiqiza ama-lens abathintana nabo abathintekayo bokuphila komsebenzi ohlukile.
