Types uye nemhando kuonana lenses

Dzosai chinooneka acuity uye kubatsira kupa nyaradzo, mukamuri kwazvino izvo. Mhando yakakamurwa maererano kugadzira zvinhu, rokuti yokutsiva, uye zvimwewo. Nokuda yakakura kudaro kupatsanura munhu anogona kusarudza vega zvomunda yepamusoro uye mutengo kusarudza. Uye kuti sarudzo yava nyore kupa iwe Kunyatsoziva chii vari kuonana lenses (mhando uye nemhando). Uchadzidzawo sei nzira yavo pakusarudza uye kuongorora kunenge kunorapwa.

A zvishoma nhoroondo

Contact lenses, uyewo magirazi - ichi asiri uchishandisa nzira wezvakaonekwa kururamiswa. Kekutanga kuti vataure pamusoro Leonardo da Vinci pakutanga 1500. Pashure 387 makore German glassblower uye Mukanova akaita girazi izvo, izvo zvinogona kuiswa zvomurwere ziso. Kubvira ipapo, kuedza akawanda kusika kwete chete quality, asiwo kusununguka kuonana lenses yave ichiitwa.

Muna 1960 akauya wokutanga lenses nyoro uye makore gumi gare gare Pakarongwa zvavo vakawanda kugadzirwa. Kwemakore siyana achitungamirira makambani munyika itsva zvemichina uye kukwanisa kunge yakatanga, uyewo zvinhu uye pamusoro chitarisiko, zvinokwanisika kupfeka lenses pasina kubvisa, pasina zvinopesana utano uye zvichingodaro.

wanhasi inopa yakawanda dzakasiyana pamusoro lenses, yakagadzirirwa kwete chete kuti aruramise chiratidzo, asi kuchinja dzinongoitika Ruvara cornea. Asi, pasinei ichi, hachizi dzose kuedza zvakare kuwedzera mutsetse-kukwira kuti zvivanakire vanoshandisa ayo uye haagumiri kukura itsva kwemarudzi. Somuenzaniso, nhasi mhando "Acuvue" kuonana lenses ndiwo:

• nokuti vanhu vane nearsightedness kana Kuona zviri mberi - rimwe zuva, nevazukuru vapfeke, mitambo, reusable, mbiri-vhiki, nokuti kutsiura makorari;
• nokuti vanhu vane astigmatism - rimwe zuva uye kwemavhiki maviri.

Variety kunyorerana lenses

To musi, pane kupatsanura zviratidzo zvakadai:

• zvichienderana kugadzirwa zvinhu: nyoro uye nesimba;
• nokutsiva rokuti: zuva, chikamu vakaronga (imwe vhiki mbiri), akaronga (nomwedzi, kota, mwedzi mitanhatu);
• kubva kupfeka modes: daily, aichinja-chinja, mazhinji uye chinopfuurira kusakara;
• Special: skleriticheskie, orthokeratology, chemasanganiswa;
• zvizorwa: ruvara uye tint.

Soft kuonana lenses

Soft kuonana lenses ndiwo inonyanya mhando. Vari basa vanhu vane hyperopia, myopia, astigmatism uye presbyopia. Ivo rinogona kushandiswa kuchirapa zvinangwa (semuenzaniso, kana pane kudikanwa kusuma zvinodhaka kupinda ziso kana kuti kuvadzivirira kuti mhanyisa apore).

Dzavo zvakwakanakira ndiwo:

• rokunyaradza kupfeka;
• kwaniso yekubata mwando;
• kukwanisa kupfuura mhepo;
• havana vainzwa pamusoro the retina.

Mhando nyoro kuonana lenses:

• hydrogel - dzine vakawanda vanotanga mwando, uye pose riri kumeso kwazvo, raichinja-chinja uye kwakavharwa nenyama;
• silicone hydrogel - dzinoratidzwa yakakwirira mwero reokisijeni permeability, uye vanoramba chimiro yavo zvakanaka.

Izvi mhando haina kushandiswa kana paine zvikanganiso zviri cornea. Nokuda kwayo kuchinja zviri izvo asina zvinozoita. The drawback pamusoro lenses kwakadaro ndechokuti kana yakaoma zvinova zvakaoma uye pfava, saka vanogona kuchengetwa chete chaiyo mhinduro. ivowo zvinoda kungwarira kukurukurwa nokuti zviri nyore kuputsa.

omarara lenses

Hard kuonana lenses vari chairayirwa ophthalmologists muzviitiko apo murwere ane shanduko pezvakaita cornea, risingagoni kugadziriswa nokubatsira nyoro mhando. Izvi zvingava Somuenzaniso, astigamtizm. kuchinjira kumamiriro zvinoda imwe nguva. Pakutanga, vainzwa Worn pamusoro pameso. Izvi kunyanya akanzwa panguva achibwaira. The chikuru chinoratidza zvakaoma kuonana lenses - vari vakaitwa inokosha mumarabhoritari pamusoro nomumwe parameters murwere, sezvo unofanira chaiyo dies romukati pose cornea pamusoro izvo.

Types kunyorerana lenses nokuti vanachandagwinyira mhando ziso:

• gasi-zvakasimba - kuburikidza navo asingadi pinda okisijeni;
• gasi permeable.

Zvakanakira lenses izvi:

• Kunogara;
• tsime chengeta chimiro yavo;
• zvinopa zvakajeka uye unopinza mifananidzo;
• nyore vakachenesa tsvina.

Maererano nenhamba, chete 10% wevarwere akapfeka zvakaoma kuonana lenses yose. The yasara 90% rinoshandiswa nyoro.

Hard mhando zvinoratidzwa nokuda kwazvo siyana astigmatism uye keratoconus. In nedanho lenses dzakadaro anoshandiswa chandagwinyira zvinhu. Ivo pakutanga akanzwa mumaziso ake nguva dzose iwe boira uye habituation kwacho kunotora nguva. Asi ichi mhando zvakakwana anoramba chimiro chayo uye hunogara, asi zvakadaro, somunhu mutemo, haakonzeri neutachiona, sezvo deposits mu dzakaoma lenses vari kuumbwa zvishoma nezvishoma pane kuna nyoro lenses.

By kutsiva izwi

Nguva Pavanotsiva kuonana lenses - a yakatarwa nguva parutivi mugadziri, iyo inogona kushandiswa vaaisangana lenses. Maererano expiry yekare vaviri inofanira kutsiviwa itsva.

Deadline for kutsiva zvinotevera mhando kunyorerana lenses nokuti meso (Photo pamusoro):

• Daily yokutsiva: ose zuva, vanopfeka mutsva peya. maonero aya anotipa kunonyanyisa kunyaradza uye kunovimbisa yakakwirira Utsanana kushandiswa. Zvakaipira ndiyo kudhura.
• Kakawanda vakaronga yokutsiva: kakawanda kupfeka itsva peya imwe kana mbiri vhiki kana mwedzi mumwe. Iyi mhando ndiyo yakanakisisa tichitarisa mutengo uye Utsanana kushandiswa. Wear lenses inogona kwemazuva pasina kutora kubvisa.
• Vakaronga kutsiviwa. Vari rakakamurwa pamwedzi, Quarterly uye Semi-wepagore. Ndiko mari zvikuru kuita. Pasinei chokwadi kuti husingakwanisi paumbwe mapuroteni uye mapuroteni deposition, ari deposition pamusoro Micro-zvinenge kuti vabudirire yakakwirira azvipire utsanana zvinokosha kushandisa yepamusoro negadziriso sokuchenesa kwavo. lenses kwakadaro regai kupa mukana dzamarudzi kusakara pamusoro usiku uye inokurudzirwa kubvisa mushure maawa 15.

Inofanira kutsiviwa pashure yakati nguva nokutsiva mhando dzose kunyorerana lenses. Uye zvivako zvavo, uye padanho utsanana kuderera pamusoro nguva, uye ichi chinobata kwete chete mufananidzo quality, asiwo hutano ziso.

Maererano kwadzinoita kupfeka

Izvi hazvina kufanana kuti kutsiviwa. akapfeka rudzi zvinoreva kunonyanyisa nguva nguva apo iwe unogona kubvisa kubatana lenses. Zviri nokuda zvimwe zvinhu zvechadenga zvinhu zvinogadzirwa kubva izvo, uyewo kutsiva izwi.

akatakura nzira inogona zvinotevera:

• zuva (DW): renzi vanopfeka mangwanani uye akabvisa usiku;
• Usazviomesera (FW): kunoita peya lenses kurara imwe kana maviri neusiku;
• -Refu kuita (EW): Contact lenses izvi mhando anogona kutakura mazuva matanhatu asina kutora kure;
• kuramba (CW): akapfeka rudzi vasingadyi yawedzera mazuva matatu.

Last kwadzinoita vainge vakamonera akazviratidza apo mu nedanho gadzira kunyorerana lenses kushandisa vanachandagwinyira gasi permeable uye silicone hydrogel zvokuvakisa. Anopa yakakwirira azvipire okisijeni permeability.

By kwenguva refu uye kuramba nzira dziri kupfeka kakawanda vakaronga yokutsiva kuonana lenses. Types vakaronga yokutsiva lenses vanoonekwa ne nguva zuva nezuva uye anonzwisisa.

Zvizorwa kuonana lenses

Zvizorwa lenses pakutanga kugadzirisa siyana vachiberekwa kana vawana kuremara ziso (semuenzaniso, corneal opacity). Nhasi, vari kushandiswa kushandura kwomuzvarirwo ruvara kwemaziso nokusika chifananidzo kujairika.

Panyaya iyi, seri izvo kunoitika, iyo izere kukuvara mvura. chimiro ichi anogadzirwa mumwe nomumwe nomumwe uye rakakamurwa corneoscleral, poluskleralny, uye scleral miniskleralnye.

Orthokeratology kuonana lenses akasiyana kudhura, kunzwisisa Kusarudza wayo kunzwisisa uye kudiwa corneal kwakaita nzvimbo yacho (chaiyo midziyo). Izvi mhando rakagadzirirwa nokururamiswa myopia kusvika diopters matanhatu, uye myopic astigmatism kusvika 1.75 diopters. Fit Vamhanyi, vanhu vanoshanda mune huruva runyararo uye zvichingodaro.

Vakaberekwa kuonana lenses zvinoshandiswa zviitiko apo murwere kunoda zvakaoma mhando, asi aripo idiosyncrasy. Pari, vari Akaratidzawo kuti rakasungwa astigmatism uye yakakwirira mwero keratoconus.

How kusarudza?

Modern ruzivo kubvumira kuti pave mhando itsva kunyorerana lenses. Chii chinogona rayira chete ophthalmologist nani. It anoita zvakafanira nzira uye inorondedzera parameters kuti itibatsire kusarudza lenses. Chiremba anonyora iwe mushonga, uye kwakavakirwa mararamiro ako uye inoda rinokurudzira mhando dzakawanda kunyorerana lenses.

Panguva kuongorora kunotsanangurwa parameters akadai kutarisana acuity mumwe ziso, refraction, pekugara uye mamiriro yacho fundus, pakukora uye Maumbirwe cornea, uye zvichingodaro. On kururama date zvinoenderana kwete unhu murwere nechaanoona, asiwo sei uchange wakasununguka kushandisa mamwe kunyorerana lenses. Nokuti ophthalmoscopy (tsvakurudzo fundus) uye nokuyerwa ari nharaunda yose curvature Somuenzaniso, zvinokosha kuti zvakafanira zvokushandisa, izvo zvinoita kuti uzere kuongorora. Saka kuti kushandisa kuonana lenses vakanga vakasununguka uye havasi kukonzera chero kutsamwa, kushanya yachiremba - ndiko chinodiwa.
