Amene magalasi akuda - yabwino? Medical malangizo ndi wosuta ndemanga

M'nkhani ino tikambirana funso la ma lenti yamitundu yabwino kwambiri. Kawirikawiri, ma lens okhala ndi zipangizo zing'onozing'ono zopangidwa kuchokera ku zipangizo zoonekera. Amaikidwa mwachindunji pamaso kuti awonjezere maonekedwe abwino (kuti akonzedwe). Chokhacho ndi zokongoletsera ndi zokongoletsera, chifukwa sizongolankhula masomphenya okha, komanso amasintha mtundu wa diso.

Malingana ndi akatswiri, chojambula ichi chikuvekedwa ndi anthu pafupifupi 125 miliyoni padziko lapansi. Njira yothetsera masomphenya pogwiritsira ntchito zipangizo zoterezi imatchedwa kukonzedwa kwa othandizira.

Oposa 40% ogulitsa mankhwalawa ndi achinyamata a zaka zapakati pa 12 ndi 25. Pakati pa iwo amene amagula makina ojambulira kwa nthawi yoyamba, chiwerengero cha anthu osakwana zaka makumi atatu ndi makumi atatu ndi makumi asanu ndi atatu (90%), ndi amayi pafupifupi 70% mwa iwo.

Zilonda zamoto komanso zamitundu

Kodi mumadziwa kuti ali ndi lenti zabwino bwanji? Zimadziwika kuti mankhwalawa amapangitsa kusintha kwakukulu pakati pa mtundu wa maulasi. Mwa njirayi, kutulutsa lens ndikofunikira kuti musinthe kapena kusintha msangamsanga. Monga lamulo, zopangidwa zopangidwazo zimapangidwa zonse ndi zojambula - kusintha mthunzi wa maso ndi kukonza maso nthawi yomweyo, ndi "zero," kwa iwo omwe akufuna kuti akwaniritse zokometsera zokha.

Malonda amitundu yambiri samakhudza malingaliro a mtundu wa chilengedwe, chifukwa ali oonekera pakati.

Kugwiritsa ntchito ma lens

Madokotala samalangiza kuti muzivala malonda amitundu yosiyanasiyana madzulo ndi usiku. Ndipotu, mopanda kuunika, wophunzirayo amatha kufotokozera, mmalo mwa kuwoneka ndi mbali ina ya mankhwala, omwe amatanthauzidwa ngati chophimba pamaso pa maso, phokoso.

Madokotala, mwa njira, amaletsedwa kuyendetsa galimoto pamalonda amitundu yosiyanasiyana, komanso kuchita ntchito zina zomwe zimafuna kuwonetseratu komanso kuthamanga kwa magalimoto.

Kupanga lenti

Tiyeni tione momwe tingatulutsire mafilimu abwino. Zimapangidwa ndi njira zingapo: kutembenuzira, kupangira centrifugal, kuponyera, komanso kuphatikiza pamwambapa.

Mothandizidwa ndi kutembenuka, mankhwala opangidwa ndi "owuma" omwe amapangidwa amatha kusinthidwa. Chifukwa cha mapulogalamu oyendetsa makompyuta ali ndi lens ndi geometry yopambana, yomwe ili ndi miyezi iwiri kapena yambiri ya kupotoka. Zotayidwa zoterezi zimapukutidwa, zowonjezereka (zodzazidwa ndi madzi) ku ziyeneretso zoyenera ndikugwiritsidwa ntchito poyeretsa mankhwala. Kenaka iwo amawotchedwa, oyesedwa, osakanizidwa, olembedwera ndi olembedwa.

Kutayidwa kumaonedwa ngati njira yochepetsera nthawi kusiyana ndi kutembenuka. Choyamba, timapanga timitengo tachitsulo. Ndipo pazigawo zonse zazitsulo zamalonda mumafunikira matrix anu. Malingana ndi izi zothandizira, akatswiri a pulasitiki nkhunizo mawonekedwe: madzi amadzimadzi amatsitsimutsa motsogoleredwa ndi ultraviolet. Lenti yomalizidwa ndi lopukutidwa, losungunuka, losakanizidwa, losawilitsidwa ndi phukusi.

Inde, makalenseni opambana omwe tiwone nawo, ndipo tsopano tipeze zomwe zimatchedwa centrifugal molding. Imeneyi ndiyo njira yosavuta yowonjezeretsa mapiritsi apamwamba. Ndipo iye akukhudzidwa ngakhale lero. Madzi amadzimadziwa amalowetsedwa mu mawonekedwe enaake, pomwe amapezeka poyera mazira a ultraviolet kapena kutentha kwake. Zotsatira zake, zimakhala zovuta. Kenaka, workpiece imachotsedwa ku nkhungu, kutungidwa ndi kusungunuka.

Chimodzi mwa ziwonetsero za njira yophatikizana yopangira makalenseni amodzi ndi njira yowonongeka III. Ndi njira iyi, kutsogolo kwake kwa lens kumapangidwa ndi centrifugal molding, ndi kumbuyo pamwamba potembenuka.

Ambiri opangira lens

M'munsimu muli mndandanda waukulu kwambiri komanso wotchuka kwambiri opanga ma lens:

• Neo Vision.
• Jonson & Jonson (Acuvue brand).
• Masomphenya a CIBA.
• Cooper Vision.
• Bausch & Lomb.
• Maxima Optics.
• Interojo.

Maselo oyera

Komabe, ndizilonda zamitundu iti zili bwino? Tiyeni tiyang'ane pa magalasi oyera a contact. M'dziko lamakono, nthawi zambiri amagwiritsidwa ntchito monga chofunika kwambiri cha masewera, tchuthi kapena phwando. Ndipotu, angathe kusintha chifaniziro cha umunthu kuti chinthucho chikhale chosiyana kwambiri ndi anthu ambiri ndikukhala pakati pa magetsi!

Posachedwapa, makina opangidwira amagwiritsidwa ntchito ngati njira yothetsera kufooka kwa masomphenya. Masiku ano amasewera ndi kukongoletsa.

Kawirikawiri, ambiri amanena kuti magalasi oyera ndi amitundu obiriwira kwambiri a holide kapena masewera olimbitsa thupi. Ndipo zedi-zimagwirizana ndi aliyense. Magalasi oyera amasintha kalembedwe ndi kupanga chithunzi chozizwitsa.

Zilonda zamkati

Mwinamwake mawonekedwe a lenseni ndi abwino kwambiri? Tiyeni tiphunzire zinthu izi. Kawirikawiri, mwapadera a magalasi oterewa ali ndi kuthekera kwawo kupatsa maso mtundu wina, kuwala ndi kusunga kwachinsinsi kwa chiwerengero cha mtundu wa munthu.

Amayi ambiri omwe adakumana nawo adakumana ndi mawonekedwe a ma lens. Pambuyo pake, pogwiritsa ntchito, mukhoza kupanga maloto odabwitsa ndikupeza maso a mthunzi wosiyana. Koma mankhwalawa alibe cholinga chokongoletsera: amateteza maso ku ultraviolet oopsa.

Mwa njirayi, kansalu kakang'ono kamene kamakhala kamene kamakhala kamene kamalimbitsa mtundu wa maso, kumapangitsa kuti iwonetsere, kapena kusintha maonekedwe awo. Mbali yodabwitsa ya mankhwalawa ndi kusowa kwa lingaliro la "chidole", mawonekedwe achirengedwe. Kawirikawiri, zinthu zoterezi zimapangitsa kuti masomphenya ayambe kuwongolera, okhala ndi ma diopters ambiri.

Mwinamwake mwakhala mukuganiza kuti ma lenses awa ndi abwino kwambiri? Mwina izi ndi zoona. Mwa njira, mawotchi opangidwa ndi mawonekedwe opangidwa ndi mitundu itatu. Chifukwa choyamba mungathe kusiyanitsa ndi maso anu, kuti muwoneke bwino. Mtundu wachiwiri wa lens udzawunikira mthunzi wa iris yanu, kuwonjezera kuwala kwa maso anu.

Chinthu chachitatu chimasintha mtundu wa iris, zochuluka kwambiri zogwiritsa ntchitoyi zimatchedwa mitundu. Tsoka ilo, silikuwoneka mwachirengedwe ngati mtundu woyamba ndi wachiwiri wamagulu, koma siwodziwika bwino pakati pa anthu.

Kufotokozera kwa white lenses

Anthu ambiri amakhulupirira kuti ma lenti oyera ndi abwino kwambiri. Nchifukwa chiyani akuganiza choncho? Zimadziwika kuti pakupanga mapulogalamu oyera, njira zenizeni komanso zamakono zamakono zimagwiritsidwa ntchito. Ichi ndi chifukwa chake zodabwitsa izi zimasintha kakhadini munthuyo popanda chovulaza thupi lake.

Ziwerengero zimati pakati pa mitundu yonse yokongoletsera, azungu lero amasangalala kwambiri. Nchifukwa chiyani izi zimachitika? Inde, tinkakonda kulankhula ndi anthu, kuyang'ana m'maso mwawo. Kuchokera pamenepo timapeza zambiri zambiri za momwe timagwirizanirana ndi maganizo ake.

Tangoganizani kuti mwadzidzidzi munthu wina yemwe ali ndi ana oyera akuonekera pamaso panu! Izi zingakuchititseni kudabwa kwakukulu, komanso chidwi mu njira yowopsya, yoyambirira komanso yokongola.

Ndipotu, nyemba zamalonda zamtundu woyera zimasiya munthu aliyense wosamvetsetsa.

Ndicho chifukwa chake mankhwalawa akukhala otchuka kwambiri lerolino. Anthu amawapeza ntchito zambiri: amagwiritsidwa ntchito pa maphwando okondweretsa, zithunzi, machitidwe muwonetsero, zikondwerero ndi zina zotero. Khalani monga momwe zingathere, magalasi oyera amabweretsa zest ku chithunzi cha umunthu.

Ubwino wa magalasi oyera

Inde, tsopano ambiri akuzunzidwa ndi funso la magalasi achikuda abwino. Pakalipano, tiphunzira zoyenera za white lenses:

• Limbikitsani ndondomekoyi ndi zokongoletsera maso ndi zokopa.
• Yesetsani kuwonetsera umunthu wa chirengedwe.
• Kokani chidwi cha onse omwe alipo ku chinthucho.

Kawirikawiri, m'dziko lamakono, njira zowonetsera zimadabwitsa kwambiri moti nthawi zina zimangodabwitsa kwambiri.

Masiku ano, akatswiri apamwamba a ogulitsa malonda omwe amagwiritsira ntchito zida zothandizana nawo amathandizana bwino ndi ojambula otchuka. Monga lamulo, chifukwa cha ntchito yawo ikuwoneka mochuluka kwambiri mwa mitundu yosiyanasiyana ya zikondwerero (zokongoletsera) ndi magalasi a scleral.

Kusiyana kwakukulu pakati pa mapuloteni a carnival ndikuti ali ndi chitsanzo chachilendo kapena chithunzi chosangalatsa. Koma mapuloteni a scleral mu mtundu umodzi amatha kuphimba khungu la diso.

Mwa njira, akatswiri ndi sclera anapanga magalasi oyera. Ambiri amanena kuti ndi malonda abwino kwambiri. Koma si onse omwe angakhoze kuwapeza iwo. Ndipotu, chisankho choterechi chikhoza kupangidwa ndi munthu amene amayamikira zachilendo, yemwe amazoloŵera kumenyana ndi anthu omwe amamuzungulira komanso amene salekerera okhaokha. Simungakayikire: diso loyela limene alibe mwana lidzadabwitsa aliyense.

Tiyenera kukumbukira kuti kawirikawiri zoyera zamakono zimagwiritsidwa ntchito ndi stylists m'mafilimu, muwonetsero ndi masewera a zisudzo. Motero amapanga chithunzi chojambula.

Malangizo

Choncho ndi mitundu iti ya lensulo yomwe ili yabwino kwambiri? Tidzapita patsogolo ku nkhaniyi yovuta. Masiku ano ndi zophweka kugula majekensi oyera. Pa salon iliyonse ya intaneti, mu sitolo yaikulu kwambiri ya optics, mungapeze zodzikongoletsera zazikulu za mankhwalawa. Zoonadi, pano mitengo ikusintha kuchokera pamwamba kufika pamalo ovomerezeka.

Timatsindika kuti musagule lens popanda kufunsa ndi katswiri wothandizira kukonza kapena ophthalmologist. Poyamba, malonda a scleral anapangidwa kuti akwaniritsidwe. Masiku ano, mankhwalawa amagwiritsidwa ntchito kwambiri ndi oimira achinyamata.

Kodi mungasamalire ma lenti oyera?

Ndi malonda otani a mtundu wabwino omwe ali abwino ndipo omwe ali oipitsitsa, tidzapezapo patapita nthawi. Tsopano tiyeni tiwone momwe kuli kofunikira kuyang'anira zitsulo zoyera. Pambuyo pake, chifukwa cha chisamaliro cholakwika ndi kusankha kolakwika malingaliro munthu amayamba kukhala wosasangalala pamene agwiritsa ntchito.

Kwenikweni, lamulo la kusamalira ma lenti woyera silosiyana ndi mfundo zomwe zimagwiritsidwa ntchito kwa mitundu ina ya malonda. Zimadziwika kuti madokotala samalangiza kugwiritsa ntchito mapuloteni ndi scleral lens kwa nthawi yaitali.

Njira yabwino ndikugwiritsira ntchito pokhapokha pa nthawi ya mwambowu. Pano ndi koyenera kusunga nthawi yotalika yotenga mankhwala - maola asanu ndi limodzi. Muzilonda zamalonda zoterezi amaletsa kugona.

Tiyenera kudziŵa kuti chiwerengero cha mankhwalawa chimasowa mpweya wokha, chikhoza kuchepa nthawi yomweyo, ndipo chifukwa chake, diso limasowa.

Ndipotu, ngati kuli kolakwika kugwiritsira ntchito lenti, mukhoza kuthana ndi zotsatira zoipa kwambiri. Izi zimaphatikizapo kuyaka, ndi maso ofiira, ndi kuwonetsa kwakukulu, ndi zina zowonongeka. Madokotala amanena kuti nthawi zina zimatha kukhala ndi edema yamakono!

Ndicho chifukwa chake muyenera kuyang'anitsitsa kutsata malamulo ovala malonda ndi kusamalira mankhwala osalimba. Pokhapokha ntchito yawo idzakhala yabwino, yotetezeka ku thanzi lanu. Ndipo, ndithudi, magalasi oyera adzakhala ngati chokongoletsa chenicheni ndi gawo lowala la chithunzi!

Kuyika ma lenti oyera

Zochititsa chidwi, ndi malonda achizungu oyera omwe ali ndi mphamvu? Lero, mabungwe ambiri akugwira nawo ntchito yopanga chozizwa ichi. Timapereka chitsanzo chimodzi chokha cha magalasi oyera omwe amalowa mumasewu ogulitsira ndipo ali ofunika pakati pa makasitomala - Magalasi a Carnaval:

• Zilonda zamoto zapamwamba.
• Mtundu: kukhudzana.
• Ndandanda ya ntchito: masana, usiku.
• Njira yowonjezera: masiku 90 aliwonse.
• Mission: zodzikongoletsera.

Malani othandizira a mtundu wakuda

Kodi malonda abwino kwambiri a maso a bulauni akugulitsidwa kuti ? Zambirizi zingapereke madokotala ndi akatswiri ogwira ntchitoyi. Ambiri ogula amanena kuti maso a bulauni ndi ofunika kwa ma lenti wakuda. Ndipo ndithudi, amapereka kakhadini kusintha kwa fano, kupanga maso okongola, ndi malingaliro owoneka bwino. Kawirikawiri, mankhwalawa ndi abwino ku Halowini, zikondwerero, phwando la mutu kapena tchuthi.

Malonda a blacks ndi abwino kwambiri kwa okhala ndi tsitsi lakuda. Sizomwe zilili kuti kukongola kwa maso akuda chakuda kumapanga nthano zambiri ndi nyimbo!

Vomerezani, lero mu big assortment mulole mtundu wothandizira malonda! Ndibwino kuti musankhe - funsoli ndi lovuta. Panthawi iliyonse yamagetsi a optics, sitolo ya pa intaneti imagulitsa mitundu yambiri ya ma lens omwe amaikidwiratu kapena tsiku lililonse. Ngati wogula akuwona malamulo ovala ndi kusamalira zinthu zimenezi, sangapweteke thanzi lake. Mwa njira, mtundu wa pigment mu zinthu zoterewu umayikidwa mu makulidwe a chiberekero. Ndicho chifukwa chake sichikulumikiza pamwamba pa diso, chomwe chimalepheretsa kuoneka kwa chifuwa, kupsa mtima, ndi kudetsedwa.

Tiyenera kuzindikira kuti utoto sukumana ndi madzi omwe maselo amathandizidwa. Choncho, mtundu wa zotsalira umakhalabe wowala kwa nthawi yaitali. Wopanga amatsimikizira kuti kukwanira kwa ma lenti wakuda kulibe mpaka kumapeto kwa moyo wautumiki.

Mwachiwonekere, ma lensisi yakuda ndiwo malonda abwino kwambiri! Ogula malonda okhudza iwo achoka ogulitsa m'masitolo okhawo abwino! Zoonadi, makondomu amakongoletsa masiku ano amapangidwa kuchokera ku zipangizo zapamwamba kwambiri. Ndicho chifukwa chake sichimayambitsa chisokonezo pamene chilowetsa.

Zakudyazi zimakonzedwa mokwanira, kotero kuti cornea sichitha mopitirira muyeso pamene ikugwira ntchito ndi kompyuta, monga mu chipinda chouma kapena pafupi ndi mpweya wabwino. Inde, mungagwiritse ntchito zowonjezera zowonjezereka, zomwe katswiri amakukonderani. Mwa njira, mapulogalamu ambiri okongoletsera ali ndi fyuluta ya ultraviolet, yomwe imateteza maso ku dzuwa.

Kuipa kwakukulu kwa maselo achikuda ndi deta yosasunthika ya kuyenda kwa oxygen kumaso. Zotsatira zake, zimalimbikitsa kuvala wakuda ndi malonda ena mpaka maola asanu ndi limodzi. Ophthalmologists aliyense samalangiza kugwiritsa ntchito lens kwa maola oposa atatu. Ndikofunikira kukumbukira: ndiletsedwa kugona mu malonda a mtundu wakuda! Ngati simukutsatira malamulo awa osavuta, mungathe kupeza hypoxia ndi corneal edema.

Malonda a buluu

Aliyense amadziwa kuti mthunzi wokongola kwambiri wa diso ndi wochepa kwambiri. Ichi ndichifukwa chake maulendo a buluu amagulidwa ndi iwo omwe akufuna kukhala ndi fano loyambirira.

Kukonzekera kwa makina ojambulira a mtundu wa buluu ndi waukulu, kotero mutha kusankha chogulitsidwa payekha popanda kuyesetsa.

Malonda a scleral

Ngati mapulogalamu oyambirira a scleral amagwiritsidwa ntchito pokhapokha ngati atchuka kwambiri pakati pa achinyamata. Lens ku West pop culture popanda optical mphamvu pamisonkhano mwambo, zikondwerero, maphwando. Mapangidwe a mankhwalawa ndi osakhala ofanana omwe amapereka munthuyo osati chithunzi choyambirira, komanso chinsinsi.

Sitiyenera kuiŵala kuti maselo osakanizika omwe amatha nthawi yaitali osagwedezeka, komanso momwe akugwiritsidwira ntchito, angasokoneze thanzi laumunthu. Kawirikawiri, pogwiritsa ntchito lipoti loyang'anira, lomwe limafufuza zotsatira zoipa za mankhwalawa, m'mayiko ambiri kugwiritsa ntchito magalasi a scleral analetsedwa.

Ngati mutasankha kuvala malingaliro, muyenera kupita kukaonana ndi katswiri wa ophthalmologist amene angakulimbikitseni mtundu wa mankhwala omwe mumayang'ana ndipo amakudziwirani ndi malamulo ogwiritsira ntchito musanagule.

Ndemanga

Mwina tsopano owerenga athu angavomereze. magalasi aliyense wachikuda bwino? ndemanga kasitomala kungatithandizenso kuti anthu amvetse mfundo zina. Ena mwa iwo amati anayesa ambiri magalasi wachikuda, ndalama yaikulu kusankha yoyenera ndipo anasiya pa thambo buluu. Amakonda mtundu wawo, iwo amati mankhwala Akukwana bwino ndipo kuti sapita pa maso.

Ena amanena kuti magalasi wachikuda kuonana nawo, ndipo iwo amavalira maola 15 patsiku! Kumene, ogula izi kuti maso mwatopa madzulo, ndipo iwo anayamba okayikitsa.

A ogula opindulitsa kwambiri kuti ngati kugona ndi magalasi (mwadzidzidzi kuiwala kuchotsa), kudzuka, basi mofulumira kuchotsa iwo. Pajatu maso kuyamba kupweteka zakutchire ndi fester. ogula ambiri kulemba zomwe amakonda yofiira magalasi "Oftalmiks Gulugufe."

Tikukhulupirira nkhaniyi kukuthandizani kusankha bwino magalasi wachikuda!
