Okwesithathu, aphephile. Izingilazi zephuke ona umuntu e ukushayisana. contact izinto zanamuhla aziwona nje soft futhi nezimo, okuyinto evimbela ukulimala kweso, kodwa futhi ibe nomphumela okuvikela UV, nomzimba futhi ezizihluphayo. Multifocal lens ngokufanele nsuku zonke alahlwayo ukushaya ngayo lapho ukusetshenziswa ketshezi.

Okwesine, zihlale kuyabonakala. Abanaso inkungu up, azingcoli. Futhi uma beba obonakele (wadweba singephulanga), usuku multifocal-contact lens kungasiza nje lilahle bese kwenye pair.

lens Multifocal - kuyini

Amandla ulungise ushintsho presbyopic ngezibuko unika ngokuphazamiseka okukhulu. Isiguli kungase kudingeke ukuba baphathe ezungeze futhi ushintshe 2 ngazimbili izibuko. Omunye ukugxila izinto eduze. Eyesibili yakhelwe sifinyelele acuity ezibukwayo lapho ibheka izinto ibanga.

Ukuze ukulungiswa presbyopia lens pair has a iqhubu futhi ngaphandle nangaphakathi. Amabili isikhungo optical senziwa lens multifocal esiyingqayizivele. Kuyini lokhu? isakhiwo esinjalo kohlelo optical ikuvumela ukuba ukhethe ibanga lapho ukucabangela into okwamanje. Omunye isikhungo senzelwe ngeso izinto ezizungezile, kanti eyesibili - ukuze bayamba kude.

Izinhlobo contact lens lapho presbyopia

Ngokusho indawo kwalungiswa izinkunga zokubona iphuzu, bahlukene phezu bifocal, multifocal futhi monocentric.

bifocal

Igama lazo lesibili - eziguquguqukayo. Ziyakwazi uhlobo elula. 2 zimumethe zone optical. amandla abo ehlukene yezokubona luhlinzeka ukuthi kungenzeka ukuthola isithombe esicacile kanye aseduze nakude. Lesi sikhungo optical ukusebenza emkhakheni iseduze phansi. I-Centre itholakala phezu umbono kude. Ukuze uthole isithombe njalo okucacile lens kumele kube imile phezu iso. ngazimbili okunjalo fiber amaphuzu agcwele esikhundleni.

isiyingi

Futhi kubizwa eyindilinga. A yakamuva imodeli ukuguqulwa bifocal. Ngo samuntu esinjalo, izikhungo yezokubona eduze futhi engangeneki ahlelwe therearound yanjalo. Ziyisivikelo esikhundleni izikhathi 4-5. Phakathi kolwelwesi ngokuvamile maphakathi kwalungiswa izinkunga zokubona ray okuvela kwezinye izinto ezikude. Lena indawo oluzenzakalelayo lens kanzima. Ngo embodiments ezithambile ingasetshenziswa iso evelele indawo efanayo nangesikhathi yesibili - okuphambene. Ngakho, kuyi-retina kanyekanye kwakhiwa izithombe ezimbili, refracting imisebe kude naseduze izinto. Isimiso sezinzwa esiyinhloko ekhetha okwamanje edingekayo lelivakalako.

aspheric

Amandla yezokubona lens kuhluka isikhungo ukuze azungeze ngokushelela. Kusukela maphakathi ngesakhiwo ibangana, kancane kancane lithuthela onqenqemeni, lapho yonke engaba indawo etholakala ngokuba ezikude. Lona iningi imodeli bokuphila, ngoba uma usebenza eduze umfundi is ayisesemikhulu, futhi lapho ebuka izinto ezikude, ke yandisa bese kuba umthamo langempela esifundeni neuropathy lens yezokubona.

Ukulungiswa lens eyindilinga ngoba presbyopia

Le nqubo ibizwa ngokuthi monovision. Empeleni, lokhu lens ezivamile, awayona multicenter. Uma sisetshenziswa eyodwa iso ukuze uthole isampuli esinikeziwe, futhi enye - lebanga abaseduze, le ndlela kuyinto bakhiphe elezinga eliphansi kakhulu efakwe ohlwini. Ngo isicelo yayo akulona iqiniso Binocular umbono. Basuke ngokuphelele contraindicated abashayeli, ngoba ayinawo umbono ophelele ngokwezinga, ukujula kanye nebanga emkhathini.

2. esikhundleni Lohleliwe. ngazimbili okunjalo optical zisetshenziswa emasontweni 2-3 ngaphambi ukulahlwa. Ingabe ziphephile futhi asidingi ukwelashwa eyengeziwe. Zigcinwa izigubhu ezikhethekile. Ukuze lens ngayinye idinga esitsheni ehlukile.
3. Multifocal lens nsuku zalutho. ngazimbili okunjalo optical asetshenziselwa amahora angu-24. Abadingi iziqukathi nezisombululo magciwane. Ngemva ukusetshenziswa olulodwa kulahliwe.

I evele contact lens futhi iso kwenzeka isikhathi eside. Ukuze optical pair sokukhula. Ziningi izifundo ziye zasungula ngqo isixhumanisi phakathi ubude bokusebenzisa lens futhi nenombolo owamukelwe izenzakalo. Lapho izinsuku usebenzisa optical pair, aba maningi amathuba kwezimo izenzakalo. Ngakho-ke, multifocal wosuku olulodwa contact lens etuswayo ukulungiswa presbyopia.

Ingathinta umbono stereo, bheka umahluko phakathi isithombe okucatshangelwayo futhi umuzwa izinga. Ingase yibe yinto exakayo, anda ukuzwela ekukhanyeni, isiyezi, umbono double.

Uma usebenzisa amaphuzu, kanye kalula isicelo, iziguli uqaphela ukuntuleka sobuhle bayo bifocal onobuhle. Futhi, kusimo okuphawulekayo Umkhawulo ka umbono neuropathy, bezibona ngekwendzawo. Nabo akunakwenzeka sihlanganyele emidlalweni. Futhi uma usebenzisa ngazimbili elahlukile umbono eduze nakude kuphakama izimo of esingalindelekile futhi okuqhubekayo egqoke ngamaphoyinti engeziwe.

izindlela Kuhlanganiswe ngokuvamile sihlanganise lonke nemibi esetshenziswa spoobov ukulungiswa.
