Vanachandagwinyira gasi permeable lenses: muchidimbu, vagadziri, zvikomborero uye wongororo

Vanachandagwinyira gasi permeable lenses, vanhu vazhinji chokuita Manyiminya namano, izvo zvaishandiswa makore mashoma apfuura. Vakanga zvakaoma kupfeka, uye kazhinji kukonzera akatsvuka kwemaziso. Zvisinei, unyanzvi hwokugadzira akaita akakwakuka mberi, uye ano lenses rakaoma akawanda zvakwakanakira zvichienzaniswa zvakawanda kwakajairika nyoro kusarudza.

Concept uye mhando

Contact lenses vari pachavo kubva duku segirazi zvinhu Manyiminya mano, izvo inoshandiswa chiratidzo kururamiswa, uye kuti ape dzokuwedzera decoration uye zvizorwa kushanda. Zvichienzaniswa magirazi, anopa nani peripheral zvaakaratidzwa. Mukuwedzera, achibatsirwa lenses anogona kugadzirisa zvirwere zvakadai keratoconus uye aniseikonia kuti zvisingagoni kuitwa nedzimwe nzira.

Kune classifications akawanda vakadaro Manyiminya zvigadzirwa. Vari mapoka mapoka, zvichienderana zvinobva yavari aita, kubva upenyu basa, kuti yokutsiva kakawanda, magadzirirwo, pachena, etc. Kazhinji, mhando zvinotevera .:

• munyoro;
• zvakaoma.

First kuona anoda 90% vose vanoshandisa kunyorerana lenses. Munguva ichangopfuura, Zvisinei, nemhaka michina itsva, ari kuwedzera kukurumbira uye yechipiri mhando. In pamberi chakakomba myopia, uye astigmatism zvikuru zvakaoma kuonana lenses ndiyo yakanakisisa sarudzo, sezvo, nokuda chimiro chayo uye arambe achirema, havana chete zvakarurama akaruramisa chiratidzo, asi kudzivirira kuchiita myopia. Izvi zvinonyanya kukosha vana nevechidiki. Uyewo, vanachandagwinyira lenses kazhinji vanosarudza vanhu vakwegura, sezvo zvinhu zvakadaro zvakawanda Zvinokosha zvakaisvonaka uye nani anzwe kana kupfeka, zvichienzaniswa nyoro kusarudza.

Features

Vanachandagwinyira gasi permeable lenses dzinoitwa kubva anokosha Polymers uye silicones kuti zvinopa optimum simba Manyiminya nyaya, asi panguva imwe chete kuburikidza navo zvakanaka inopfuura oxygen. Kakawanda vari kushandiswa mumamiriro ezvinhu kunodiwa yakarurama chiratidzo kururamiswa uye kururamisa matambudziko zvaakaratidzwa, mune kwakandiomera nyaya dzakadai astigmatism, keratoconus, orthokeratology, uye vamwe.

Akapiwa hunhu musimboti ichi, mumwe izvo zvinofanira Zvakanakisa wakanyatsokodzera murume, saka zvinhu izvi zvinoitwa nomumwe. Izvi zvinowanzoda anouya murwere wokutanga nyanzvi uye chirwere, akabva aita Manyiminya mano pachavo, uye chete ipapo chiremba achakwanisa kudzipfeka. Nzira kuti pakusarudza zvakaoma kuonana lenses Zvinoda refu zvichienzaniswa nyoro pfungwa yakafanana nokuti zvinoda mumwe Masvomhu.

Michina

Pane zvakawanda zviri kuti vane lenses dzakaoma. Technology Rondedzero kunoita zvakawanda yakarurama kuti utsanangure. Nekuti vazhinji repakati vanhu, shoko rokuti "dzakaoma lenses" Rinobatanidzwa vamwe kunaka ndangariro, World Association of Vagadziri kuonana lenses aida kurega izwi. Asi izvozvo akafunga rokuti "gasi-permeable lenses." Chokwadi ndechokuti, pasinei shoko "vakaoma", musiyano uyu zvakasiyana nevaya lenses kuti zvave kare sezvo nokuaita zvino kushandiswa nzira dzakasiyana chaizvo.

Modern ruzivo kubvumira kuti kunyatsotaura chinja misodzi Profile pazasi izvo, uyewo nhoroondo yomunhu ari thickening ari Manyiminya mudziyo. Pfungwa iri rwakabhadharwa kuna chimiro kumicheto ari vanachandagwinyira zvikamu, uyewo huru unhu. Nokuti chinangwa ichi, chaiwo kombiyuta Diagnostics, digitaalinen kuzvidzora akatendeukira, uyewo kushandisa hwakanakisisa uye zvinhu ano.

zvakwakanakira

Kuenzanisa vanachandagwinyira gasi permeable kuonana lenses pamwe chinyakare nyoro unokubvumira kuona nhamba makomborero, vane yokutanga.

• The cornea haina midziyo ropa, saka, unogona chete kugamuchira okisijeni kubva mumhepo. Soft Manyiminya gogorosi orifukidza chose, iro anodzivira kugoverwa okisijeni. Modern dzakaoma zvigadzirwa dzinoitwa chaizvo nezvinhu nemhaka silicones uye Polymers, vane yakakwirira mwero negasi permeability. Ndicho chikonzero vakarega zvimwe okisijeni iri tichienzanisa yakasvinuka uye akapfava kusarudza.
• Vanachandagwinyira zvakaoma kuonana lenses uyewo anopa yakanakisisa kutarisana acuity. Other kururamisa nzira musapa Somugumisiro yakadaro. Izvi imhaka yokuti vanenge cornea ose ane zvimwe hadzina kufambiswa zvakanaka. Soft gogorosi inotevedzera Maumbirwe ziso, kusanganisira zvose waro convexity uye kuora mwoyo. Vanachandagwinyira embodiments zvinopa zvakakwana sandara Manyiminya penyika. Izvi zvinobvumira nokururamiswa zvikuru zvakarurama.
• lenses izvi regai aiyanika panze uye regai zvinoda ichinyongovedza.
• Vane upenyu nokuda kwayo noukukutu uye simba.
• Vanachandagwinyira gasi permeable lenses zvakawanda nemishonga kuti paumbwe deposits siyana kuti kuwa pamusoro pavo kubva misodzi firimu. mapuroteni izvi uve tsime Kurwara uye achiipa gasi exchange.

Pasinei nokuti nyaradzo panguva kushandiswa - iri akasiyana kushandisa Manyiminya zviridzwa dzakapfavirira, michina yemazuva kubvumira kuti pave izvo zvakaoma, ndoupiko unonyanya kunyatsotevera inotevedzera Maumbirwe cornea uyewo nyore kushandisa.

kutadza

Pasinei zvakanakira vanachandagwinyira gasi-permeable lenses inosimbiswa uye zvimwe zvinhu kunaka kuti chikumbiro chavo.

• zvinogadzirwa zvakadai zvinoda kwenguva refu kuchinja uye habituation.
• Mutengo mikana yakadaro yakakwirira zvikuru kupfuura nyoro.
• Kuti basa rinokosha mhinduro zvinodiwa kuti vanachandagwinyira gasi permeable lenses.

Uyezve, Manyiminya midziyo kusarudzwa kwacho rakanyatsojeka yakaoma, nokuti vakaita nomumwe neziso rimwe.

astigmatism

Hard lenses vari rakanakira nokururamiswa astigmatism. Nokuda simba neukukutu, dzomutauro vakadaro vane uye vanoumba misodzi firimu iri pamberi pechiso chenyika ziso dziri mabhora. Pakati cornea uye izvo veshure pamusoro kuumbwa dzokuwedzera nzvimbo, uye izvo compensates kuti kuratidzwa ichi pamusoro kuremara.

Zvisinei, zvinhu zvakadaro zvakaitika, zvinokwanisika kana panova mwero astigmatism. Kana pamwero mukuru, zvingangoita kururamiswa kushandisa idenderedzwa Manyiminya mano ipfupi. Unokwanisa kushandisa zvikamu imwe chimiro. The yakanakisisa chingaitwa ichi ichava toric lenses.

sarudzo

Vanachandagwinyira gasi permeable lenses muMoscow dzakakurumbira chaizvo, asi muitiro wavo kusarudzwa zviri akaoma kupfuura kuti nyoro kusarudza. The Manyiminya chigadzirwa anofanira zvinenge zvakakwana kuenzaniswa Anterior penyika yevanhu cornea. Izvi zvinogona kuongororwa chaiwo fluorescent pendi mhando. Ndokusaka unofanira kuonana chiremba rakakodzera uyo achashandisa chaiyo nemidziyo zvakakodzera vakasarudzwa.

Mukupesana, zvinonzi nyoro, vanachandagwinyira lenses zvinoda mumwe nguva kwadzakabva. Kazhinji zvinotora mazuva 5-7, uye mune zvimwe zviitiko kunyange zvakawanda. Nokufamba kwenguva, mukuru cornea zvinoenderana uye akapfeka kunyaradza zvikurusa.

Kugadzirwa vanachandagwinyira lenses vari mubasa dzakawanda unyanzvi makambani. Yakanakisisa kuvazivisa ndivo Hofori akadai CIBA Vision (Switzerland), Vistakon (USA), Sauflon (United Kingdom), Cooper Vision (US), Clearlab (United Kingdom), Zeiss (Germany), Baush & Lomb (nemakambani kambani), Avizor (Spain ), uye vamwe. mhinduro yevatengi anoratidza kuti yega ine mativi zvakwakanakira uye kunaka, asi masangano ose kupa yepamusoro uye hwakavimbika zvokuvakisa uye yakakwirira azvipire kunyatsoshanda uye kuchengeteka rakapera zvigadzirwa.

Maintenance uye kugara zvichiongororwa

Vanachandagwinyira lenses zvinopa refu unhu chiratidzo, asi ivo vanoda basa pamunhu. Chekutanga, vaifanira zvakanaka uye nguva yokutarisira, uye chepiri kudiwa kakawanda kushanyira imwe ophthalmologist. Special pfungwa kuchengeteka mitemo kushandisa vanachandagwinyira noruzhinji lenses. Izvi zvinoshandawo kunyanya kuzobvisa uye kupfeka, uyewo utsanana.

Vanachandagwinyira gasi permeable lenses - ichi ndicho chakanakisisa chingaitwa avo vakakosha zvakarurama zvakaratidzwa kururamiswa, uye vaya vanotambura astigmatism uye nezvimwe zvinetso zvakafanana. Pasinei chokwadi kuti zvinhu zvakadai zvinoda munhu kunyatsosarudza uye zvishoma duku kupfuura munyoro azvipire kunyaradzwa, vane zvimwe zvinobatsira. Modern ruzivo kubvumira kuti pave kuita kuti kuchaita zvakarurama kuita zvose mitambo yayo, asi ndinoda kuva kupfuura dzinokodzera uye takasununguka vanhu.
