Igesi Ngesandla Esiqinile lens permeable: i Uhlolojikelele, abakhiqizi, izinzuzo kanye nokubuyekeza

Ngesandla Esiqinile igesi lens permeable, abantu abaningi elihlobene ne amadivaysi optical, ayesetshenziselwa eminyakeni embalwa edlule. Kwakumelwe nzima nakuwe, futhi ngokuvamile kubangela ububomvu samehlo. Nokho, ubuchwepheshe buye wagxumela phambili, nababhula ngezinkanyezi namuhla lens kanzima kunezimo eziningana ezisivunayo kuqhathaniswa ne ngaphezulu ongakhetha ezithambile ezivamile.

Concept nezinhlobo

Contact lens kukhona ngokwabo ezenziwe ngezinto ezincane esobala kumadivayisi we-optical, ezisetshenziswa for umbono ukulungiswa, futhi ukuze kuphunyeleliswe ezengeziwe zokuhlobisa futhi ubuhle. Ngokuqhathaniswa izibuko, zinikeza umbono neuropathy kangcono. Ngaphezu kwalokho, ngosizo lens ungalungisa izifo ezifana keratoconus futhi aniseikonia ukuthi angeke kwenziwe ngezinye izindlela.

Kunezinhlobo eziningana imikhiqizo efana optical. Basuke zihlukaniswe ngamaqembu, kuncike impahla okuvela ngazo zenziwa, kusukela ukuphila service, imvamisa esikhundleni, umklamo, obala, njll Ngokuvamile, lezi zinhlobo ezilandelayo .:

• elithambile;
• kanzima.

emehlweni Okokuqala ukhetha 90% wabo bonke abasebenzi contact lens. Muva nje, Nokho, sibonga ubuchwepheshe obusha, buthola ukuthandwa futhi uhlobo lwesibili. Ephambi kwezinduna myopia ezinzima, futhi astigmatism kakhulu contact lens kanzima kukhona ukhetho best, kusukela, ngenxa ezakheke kanye kwabantu, kungukuthi nje ngaphezulu ukulungiswa umbono ngokunembile, kodwa futhi ukuvimbela ukuqhubeka myopia. Lokhu kubalulekile ikakhulukazi izingane nentsha. Futhi, lens eqinile nakho ngeke kusize bathanda abantu abadala, njengoba imikhiqizo enjalo kukhona okuhlala isikhathi eside futhi banomuzwa kangcono lapho ukugqoka, uma iqhathaniswa naso ongakhetha esithambile.

Izici

igesi Ngesandla Esiqinile lens permeable zenziwa kusukela polymers akhethekile silicones ezinikeza elikhulu amandla sihloko optical, kodwa ngesikhathi esifanayo ngokusebenzisa kwabo sihamba kahle umoya-mpilo. Ngokuvamile bajwayele ezimweni lapho isidingo olunembile umbono ukulungiswa futhi ukulungisa izinkinga nge umbono, ezimweni ezinzima kakhulu, ezifana astigmatism, keratoconus, orthokeratology, nabanye.

Banikezwe izici zalesi samuntu, lens ngamunye kufanele Lifanele indoda, ngakho mikhiqizo zenziwa ngamunye. Lokhu kuvamise iza nesineke lokuqala kuchwepheshe namadivayisi kutholakala ukuthi uphethwe yini, khona-ke wenza i-optical ngokwabo, futhi kuphela ngaleso sikhathi udokotela uzokwazi sizigqoke. Inqubo ukukhethwa contact lens kanzima ithatha isikhathi eside uma kuqhathaniswa ne inketho ezithambile efanayo ngoba idinga izibalo ngabanye.

ubuchwepheshe

Kukhona izici eziningana ukuthi kufanele lens kanzima. incazelo Ubuchwepheshe ivumela esinembile okuchaza. Ngenxa yokuthi abantu abaningi oseqinile, igama elithi "lens kanzima" lihlotshaniswa izinkumbulo ezithile ezimbi, i-World-Association of abakhiqizi contact lens ahlinzekwa ukuyeka eside. Kunalokho ke ezihlongozwayo igama elithi "ama-lenses igesi permeable." Iqiniso liwukuthi, naphezu elithi "ezinzima", lokhu kuhluka iyahluka kwenye labo lens eziye zasetshenziswa ngaphambilini ngokwenza kwabo manje basebenzisa izindlela ezihlukene kakhulu.

ubuchwepheshe besimanje ukuvumela ukuba ngokunembile ulungise iphrofayela izinyembezi ngezansi lens, kanye iphrofayili ukuqina idivayisi optical. Ngokukhethekile ikhokhelwa ukuma emaphethelweni izingxenye eqinile kanye izici eziyinhloko. Ngenxa yale njongo, efana ncamashí ikhompyutha ukuhlola, ukulawula digital turning, kanye ukusebenzisa nqampuna umhlabeleli futhi ngezinto zokwakha zesimanje.

izinzuzo

Ukuqhathanisa igesi eqinile nakho ngeke kusize permeable contact lens elithambile bendabuko ikuvumela ukubona eziningi izinzuzo, okuyinto yokuqala.

• I-cornea ayinakho imithambo yegazi, Ngakho-ke, ungathola kuphela i-oksijini evela emoyeni. Soft lens optical asimboze ngokuphelele, okuyinto okuvimba umoya-mpilo. Modern imikhiqizo kanzima zakhiwe ngezinto ezikhethekile ngesisekelo silicones kanye polymers, okuyinto abe izinga igesi permeability. Yingakho ake umoya-mpilo owengeziwe ngokuziqhathanisa ongakhetha ezicashile kanye soft.
• Ngesandla Esiqinile contact lens kanzima futhi sinikeze engcono acuity ezibukwayo. Ezinye izindlela ukulungiswa ungayeki miphumela. Lokhu kungenxa yokuthi cishe njalo cornea has semfene ezithile. lens Soft kulandela ukuma iso, kuhlanganise nayo yonke convexity yayo nokucindezeleka. embodiments Ngesandla Esiqinile ukunikeza ngokuphelele flat surface optical. Lokhu kuvumela yokulungiswa ngokunembile kakhulu.
• Lezi lens musa Ewufrathe out futhi asidingi moistening.
• Sinenkosi ukuphila isikhathi eside ngenxa ubulukhuni bayo kanye namandla.
• igesi Ngesandla Esiqinile lens permeable amelana ngaphezulu ekwakhekeni imali ehlukahlukene ingena ezinhlwini ukuthi phezu kwabo kusukela ifilimu izinyembezi. Lezi amaprotheni zingaba umthombo komzimba futhi sibe sibi negesi lokushintshisana.

Naphezu kweqiniso lokuthi induduzo ngesikhathi ukusetshenziswa - lena inzuzo elikhethiwe amathuluzi ezithambile optical, ubuchwepheshe yesimanje ukuvumela ukudala lens kanzima, okuyinto esicishe kulandela ukuma cornea futhi kulula ukuyisebenzisa.

amaphutha

Naphezu izinzuzo eqinile nakho ngeke kusize lens igesi permeable zigqanyisiwe kanti ezinye izici ezingezinhle isicelo sabo.

• imikhiqizo enjalo zidinga isikhathi eside okuzivumelanisa futhi habituation.
• Intengo ongakhetha ezinjalo ingaphezulu kakhulu ukwedlula elithambile.
• Ukuze kunakekelwe izixazululo ekhethekile ayadingeka igesi eqinile nakho ngeke kusize lens permeable.

Ngaphandle kwalokho, i-optical Ukukhetha imishini nqubo kubenzima, ngoba zenziwa ngamunye esweni ngalinye.

astigmatism

lens Hard mahle yokulungiswa astigmatism. Ngenxa amandla kanye ubulukhuni, ezahlukeneyo enjalo ukugcina futhi yakha izinyembezi ifilimu phezu phambi iso ngesimo sphere. Phakathi cornea kanye ebusweni lens ezingemuva kwakheka isikhala eyengeziwe, futhi lapho ivala ngalokhu kubonakaliswa yokungafaneleki.

Nokho, umphumela onjalo, kungenzeka uma kukhona degree elincane astigmatism. Uma ezingeni mkhulu, kungenzeka ukulungisa usebenzisa amadivaysi eyindilinga optical sinciphile. Ungasebenzisa izingxenye olunye uhlobo. Inketho kangcono lokhu kuzoba lens toric.

Ukukhetha

igesi Ngesandla Esiqinile lens permeable eMoscow athandwa kakhulu, kodwa inqubo Ukukhetha kwabo eziyinkimbinkimbi kuka ngokukhethwa kukho esithambile. Umkhiqizo optical kumele cishe ngokuphelele ukufanisa kobuso anterior we-cornea womuntu. Lokhu kungenziwa ihlolwe nge ekhethekile Fluorescent upende hlobo. Yingakho kudingeka ukuba uxhumane nodokotela ezifanele labatawusebentisa imishini esikhethekile Ukukhetha efanele.

Ngokuphambene, it is elithambile, lens eqinile nakho ngeke kusize zidinga kwenkathi ethile lithathelwe. Ngokuvamile kuthatha izinsuku 5-7, futhi kwezinye izimo nakakhulu. Ngokuhamba kwesikhathi, i-cornea uvuma futhi egqoke induduzo luyanda kakhulu.

Ukukhiqizwa lens eqinile nakho ngeke kusize bekwi eziningi izinkampani ezithile. I aziwayo engcono zinde ezifana CIBA Vision (Switzerland), Vistakon (USA), Sauflon (United Kingdom), Cooper Vision (US), Clearlab (United Kingdom), Zeiss (eJalimane), Baush & Lomb (inkampani esemazweni amaningi), Avizor (Spain ), kanye nabanye. Izimpendulo abathengi abonisa ukuthi indlela ngayinye has ezinhlangothini zalo emihle nemibi, kodwa zonke izinkampani zinikeza eliphezulu futhi izinto onokwethenjelwa futhi ezingeni lelisetulu nekghono nokuphepha imikhiqizo siphelile.

Maintenance and zokuqapha njalo

lens Ngesandla Esiqinile unikeze high umbono, kodwa bafuna ukuba umthwalo okwengeziwe muntu. Okokuqala, isidingo ngabo kahle futhi njalo ukuze anakekele, futhi okwesibili, isidingo ujwayele ukuvakashela kudokotela wezifo zamehlo. ukunakekela okukhethekile unikezwa imithetho yokuphepha ukusetshenziswa contact lens eqinile. Lokhu kusebenza ikakhulukazi ukuba akhumule wembatha, kanye nezinto eziphathelene nenhlanzeko.

igesi Ngesandla Esiqinile lens permeable - lena ukhetho best kulabo ibalulekile olunembile umbono ukulungiswa, futhi kulabo abaphethwe astigmatism nezinye izinkinga ezifanayo. Naphezu kweqiniso lokuthi imikhiqizo efana zidinga ezikhethwe ngokucophelela futhi kancane ezincane kuno ezingeni omnene wenduduzo, banayo nokunye. ubuchwepheshe besimanje ukuvumela ukudala izinketho ukuthi ngeke nje enze ngokunembile yonke imisebenzi yawo, kodwa kwakuyoba elula kakhulu futhi ukhululekile ngabantu.
