Abasebenzisi abaningi bekhompyutha bakhononda ngokukhathala kwamehlo, ubomvu babo, ubomvu, umbono obonakalayo, ikhanda. Zonke lezi zibonakaliso ze-syndrome ye-visual visual. Izikhalazo eziningi mayelana nesimo somzimba zivela othandana be-lens othintana nabo. Ngokusetshenziswa okuqhubekayo kokuqapha, imvamisa yokukhanya iyancipha, okwenza iso ne-lens yokuxhumana zome. Kukhona umuzwa wokungahambi kahle, isifiso sokususa amalensi okuxhumana futhi ubuyele kuze kube phakade kumaphoyinti. Okunye ukukhululeka kunganikezwa ngamaconsi akhethekile okuphuthumayo. Kuvela, ukugqoka izibuko ehhovisi kunengqiqo. Uma ubhekene nocindezelo olunzima ebhuloho lempumu nokukhathala kwamehlo, ungasusa izibuko, uphinde uhlale esihlalweni sakho futhi uvumele amehlo akho aphumule, angeke asebenze uma uxhumane namalensi. Ososayensi baseMelika baseWashington bahlanganyela ekwakhiweni kwamalensi anezincircikhi ezifakiwe. Lokhu kugcwaliswa kuzokuvumela amalense oxhumana nabo ukuba akhulise izinto futhi abonise idatha ehlukahlukene ngabo ngabo lens. Esikhathini esizayo esiseduze le ntsha izovela ezitolo. Ngendlela, kuye ngokuthi izibuko noma contact lens akukwenzeki! Konke lokhu kuyize!
Ukuze uthole induduzo
Futhi ngemuva kwezibuko, futhi ngemuva kwama-lens badinga ukunakekelwa okufanele. Lokhu okugcina kufanele kugcinwe esitsheni esikhethekile, isikhathi ngasinye lapho kushintsha isixazululo. Izibuko zidinga ukucinywa, kaningi ngokwanele ukuze zingenalo utshwala namabala phezu kwabo, futhi ukubona ukuthi izibuko zinyanyiswe - kulokhu, i-lens inenzuzo ecacile. Kunezinhlobo ezahlukene: usuku olulodwa, amaviki amabili, isigamu sonyaka. Kuyinto elula kakhulu ekuseni, kanye nokwamukelwa, isibonelo, yinkimbinkimbi ye-multivitamin, ukuze uthole i-lens kusuka ku-blister bese uyibeka, futhi kusihlwa ukususa nokulahla. Ngokungafani nama-lens asetshenziswe isikhathi eside, asikho isidingo sokuwagcina ezitsheni ezikhethekile, ukuthola izixazululo. Ngaphezu kwalokho, ngokuhamba kwesikhathi, ama-lens agqoke isikhathi eside alahlekelwa ezinye zezakhiwo zawo, zihlungiwe, lapho okuthiwa i-detritus-mucus inqwabelene namaseli afile ebusweni be-eye ahlanjululwe, futhi akuzona zonke izixazululo nazo ezingabhekana ngokuphumelelayo. Lokhu kwandisa ingozi yokutheleleka. Kungcono ukusebenzisa lens ezilahlayo.
Ngempilo
Uma unomkhuhlane, kungcono ukusebenzisa izibuko, ngoba ngezifo zokuphefumula, kukhona ukuvuvukala okusebenzayo kwe-conjunctiva ne-epithelium ye-cornea ngenxa yokukhwehlela okuqinile nephunga eligijima. Futhi, izibuko ziyadingeka ukuze kuhlanganiswe nesifo (iso) esithathelwanayo, ngakho-ke ukuphuma kwenhlanzi kuphuma amehlo akho, futhi awusenwe igciwane futhi.
Ngesithombe
Yiqiniso, ngosizo lwezibuko ungashintsha isithombe, ube yindodakazi yebhizinisi, unobhala omuhle noma uthisha oqinile. Kodwa ngokufanayo, ngokungafani nama-lensi, abakwazi ukugcizelela ubuhle bemvelo. Uma unamehlo aluhlaza okwesibhakabhaka, ungabenza luhlaza noma lubomvu. "Idamu elimnyama" leso, ngokuphambene nalokho, lingenziwa lula kakhulu. Ngaphandle kwalokho, vele ufake isitifiketi kumbala wakho wemvelo. Ukuze wenze lokhu, kunama-lens axhumene nawo angakwazi ukufihla ukukhubazeka okuthile okubukwayo futhi ashukumise kahle umbono wamehlo, kuye ngokuthi isithombe esikhethwe yisiguli. Ngeke bashintshe umbala wamehlo amnyama noma alula, kodwa azokwenza ubukeka obonakale futhi engeza ukukhanya. Umphumela wezitho zomzimba walezi lens kungenzeka ungabonakali. Uma usesaba ukugqoka ama-lens angama-contact ngoba ungafuni ukubona umhlaba ohlaza okwesibhakabhaka noma we-pink, thola phansi: lokhu ngeke kwenzeke. Kusukela ekuqalisweni kwamalensi ombala, ubuchwepheshe bokukhiqiza kwabo buguqukile kakhulu. Ama-lens wamanje, ngisho ne-iris abadwetshiwe kuwo, anikeze isithombe semvelo, ngoba ama-lens ezinemibala anendawo ebonakalayo ebonakalayo lapho kukhanya kuphuma khona. Uma i-lens iboshiwe (imbala enemibala eluhlaza okwesibhakabhaka, eluhlaza okwesibhakabhaka, ohlaza okwesibhakabhaka noma ohlaza okwesibhakabhakeni), khona-ke ingxenyana ye-polymeric yombala ayidluli ku-20%, engashintshi umbono wokubala ngemibala enjalo. Kodwa hhayi nje umbala wamehlo ungashintsha amalense oxhumana nabo. Bangakwenza ube yi-zombie noma umuntu ongavamile. Ama-lens we-carnival afana ne-crazy and fun angenza lokhu. Lokhu kuyasiza kakhulu kumaqembu, lapho ungavela ngaphambi kwabangani bakho ngendlela entsha engalindelekile. Ungagqoki ama-lensi ezinemibala emahoreni angaphezu kuka-12: ngenxa yezinyosi ezingenayo i-oksijeni ephezulu yokubeka amandla, nama-lens afana ne-crazy - amahora angaphezu kuka-4-5. Ukubekwa kwawo okwenyuka kwe-oksijini kuncane kakhulu, akuhlosiwe ukugqoke unomphela ngenjongo yokulungiswa kombono. Lesi sibalo sitholakala, kufaka phakathi endaweni evulekile ye-lens, eyabangela ukubuka okubukwayo. Ngakho uzigqoke njengokungavamile ngangokunokwenzeka, ngesikhathi.
Ukuzijabulisa okusebenzayo
Uma sikhuluma ngokuphumula, ikakhulukazi ogwini, ukhetho luyabonakala - lens. Ngeke bavele lapho bedlala i-volleyball yasebhishi, kanye nabo ungabona konke ubuhle bezwe elingaphansi kwamanzi, uma ugqoka imaski ekhethekile yokubhukuda. Nokho, uma ungumlandeli wezibuko, ungahle uhlele amafomu akhethekile, ama-anatomical. Bathuthukiswa kangcono futhi bangaboni ngaso linye ngokunyakaza okusebenzayo, futhi ungakwazi ukugcina "izimfihlo" zobunzulu, futhi ngaphandle kokuzinikeza. Manje izibuko ezikhethekile zokubhukuda ne-diopters zakhiwe. Kusukela ekuzalweni kwama-lens wokuxhumana, kunamahemuhemu amaningi ngabo.
Amanga mayelana nama-contact lens:
1. Uma ngabe mina noma udokotela engakwazi ukufaka i-lens yokuxhumana, angikwazi ukuwagqoka. Lokhu akulona iqiniso. Udinga ukubekezela, ukulahla ukwesaba uphinde uzame ukufaka ama-lens phambi kodokotela. Ngemuva kwemizamo eminingi ephumelelayo, ukugqoka ama-lens akuyeke kubonakale kunzima kakhulu, iso lizosetshenziselwa ukuhlukumeza. Ngezinye izikhathi isiguli ngokwayo siba ngcono ukugqoka i-lens, kodwa udokotela ngokuvamile usiza ngokuqondisa isandla sesiguli ngendwangu esweni.
2.Contact lens iyingozi emehlweni, ngoba njalo uma uwabeka, ulimaza i-cornea. Hhayi ngempela. Kukholelwa ukuthi izakhiwo ze-microtraumatic zamehlo lapho zigqoka i-lens, kodwa akudingekile ukuba zikhulume ngakho, ngokuqondile, mayelana nanoma yikuphi ukubaluleka kokubaluleka komtholampilo lapho usebenzisa amalensi kusuka ezintweni zanamuhla. Amalensi okuxhumana okwamanje awalimazi iso, ayindlela elula futhi ephephile yokulungiswa kombono.
3.Ukuhlangana kwamalensi kungabangela ukutheleleka kanye nezifo zamehlo. Yebo, kungenzeka, uma ama-microorganisms angena esweni nge-lens. Izimbangela zokubonakala kwamagciwane ezincane kuhlosiwe zihlotshaniswa nokungahlanjululwa kahle kokungcola, ukungcola kwesitsha, ukusika ngaphezulu kwama-lensi. Ukuze unciphise ukutheleleka okungenzeka, kungcono ukusebenzisa i-CL yosuku olulodwa: kulokhu, isikhathi ngasinye i-lens ehlanzekile nehlanzekile ifakwa iso, futhi azikho izixazululo neziqukathi - imithombo eyinhloko yokutheleleka.
4. Uma ugqoka ama-lens, udinga ukusebenzisa izimonyo ezikhethekile zokuhlobisa. Yebo, lokhu kunjalo, uma ugqoke amalensi udinga ukusebenzisa isitifiketi esikhethekile (ngokuvamile emaphaketheni ibhaliwe "kuvunywe yi-ophthalmologists") kanye nezimonyo ze-hypoallergenic. Akukhuthazwa ukusebenzisa i-mascara ngezingxube ezikhethekile, njengezintambo noma izinwele ze-mink: ziyaqhuma futhi, ukufika kuma-lens, kubangela izinzwa ezingathandeki.
5. Angidingi ama-lens okuxhumana nawo, ngoba ngisebenzisa izibuko kuphela lapho ngisebenza kukhompyutha futhi ngisesitimeleni semoto. Lokhu kuyisimo esingalungile esihle. Uma udinga izibuko ngemisebenzi ethile, kusho ukuthi unamahloni amancane. Futhi idinga ukulungiswa okusebenzayo njalo. Ukungabikho kwalokhu kuholela ekucindezelweni okungeziwe emehlweni nasebuchosheni, okufaka isandla ekuthuthukisweni kombono. Ngaphezu kwalokho, ukusetshenziswa kwama-lens okuxhumana lapho ushayela imoto kungeyona insimu yokubukwa, akukho ukuhlaselwa kwe-lateral, cishe akukho ukunciphisa ezintweni ngenxa yokuthi i-lens iyisistimu eyodwa yokukhanya ene-eyeball.
6. Amalensi wesizukulwane esisha avikelekile emisebeni ye-UV, ngakho-ke izibuko zelanga azidingekile ngokuphelele. Lena inganekwane. Izibuko zelanga zidingeka, ngoba i-lens ivikela kuphela i-cornea nezingxenye zangaphakathi zeso elangeni. Eminye iso namajwabu amehlo ahlale evulekile, ngakho-ke kudingeka adalwe ngezibuko.
Amaphuzu ayishumi ngaphambili
Akunandaba, umbono wakho uphansi noma ulungile - usadinga ukuvikela amehlo akho elangeni. Into esemqoka ukukhetha izibuko zokukhanya ezilungile. Kunezinqubo ezimbalwa zokukhetha.
Ngezinga lokuvikelwa kwe-UV
Ubufakazi bokuvikeleka okwanele kwezibuko ezivela ku-ultraviolet kungaba yi-"UV 400", ebonisa ukuthi ivikela amehlo emisebeni yelanga elingaphezulu kuka-400 nm (lokhu kukhanya kwe-spectrum ultraviolet 290-380 nm). I-quartz lens (ingilazi evamile) ivimbela ngokuphelele ukungena kwemisebe ye-UV, izibuko ezinezibuko ezinjalo zingathembeka. Lawa ma-lens anenye futhi: ayiboni kakhulu. Kodwa impikiswano yabo eyinhloko yi-fragility ephezulu. Njengamanje, amalensi ayenziwe ngezinto zokwenziwa kwe-polymeric ayanda kakhulu. Uma ukhetha lezi zibuko, unake kakhulu ukuthunyelwa kwe-ultraviolet.
Ngezinga lobubumnyama babo
Kunama-alding angu-5 e-shading ama-lens eye-glass (80-100% wokukhanya okudluliwe - amalalensi avulekile, ama-43-80%, 18-43%, 8-18% no-3-8% - ukudlula kwamalensi amnyama). Ukuzikhethela okubonakalayo noma, ngokuphambene, izibuko zemibala kuncike lapho umuntu azokusebenzisa khona. Ngokwesibonelo, ukuhamba ezintabeni kunengqondo ukuthenga izibuko ezimnyama kakhulu. Uma uzophumula ekukhanyeni okuphansi, khona-ke ukukhanya okuningi. Kubantu abaningi, izibuko ezinezikhwama zokukhanya ezingu-18-43% zifanelekile - Lezi yizibuko zelanga zonke, kumalebula okubhalwa kuyo Inhloso KaGeneral. Kumele kukhunjulwe ukuthi indawo yesilazi yesikhumba esinciphisa ukudluliselwa kokukhanya.
Ngokomumo wesakhiwo
Isici esibalulekile ekukhetheni izibuko ukuma kwazo. Lokhu akuyona indaba nje yesithombe. Amafreyimu okwenziwe nge-anatomical shape avumela ukuvikelwa okunokwethenjelwa ngokumelene ne-ultraviolet, kufaka phakathi ukukhanya okungaqondile okuhlakazekile amehlo nesikhumba se-conjunctiva. Kodwa namanje ukukhetha uhlobo lwezibuko kunqunywa ngenhloso yabo eyinhloko. Ukuze isitayela sedolobha namabhizinisi, isibonelo, "ama-aviators", ukuhamba ezweni noma ukudlala ogwini, kufanelekile ezemidlalo ezenzakalelayo. Uma ukhetha izibuko, ukubeka okubalulekile, ukufika kwayo ebhuloho lempumu, ubude kanye nokuma kwamathempeli. Ukusetha okungalungile kungabangela ikhanda.
Ngombala wama-lens
Ukuzikhethela kwezibuko zombala kuncike ekutheni isakhi sezithombe. Nokho, okokuqala, kuyadingeka ukuba unake indlela ukuthi izihlungi zokukhanya zizoshintsha kanjani umbono obukwayo. Ukuphazamiseka okuncane kokubheka kubangelwa ama-lens ama-grey, aluhlaza nensundu. Umbala ohlaza okwesibhakabhaka. Ngaphezu kwalokho, izibuko zangaphambili nezibuko ezinjalo zazisetshenziswa ekwelapheni i-glaucoma. Ama-lens ama-brown, mhlawumbe, awona aphezulu kakhulu futhi aphelele kuwo wonke ama-spectrum: akhipha ingxenye ebalulekile yokukhanya okwesibhakabhaka okwakumonakalo futhi akhuthaze ukwanda kokuzwela kwamehlo. Ama-lens aluhlaza okwesibhakabhaka ne-blue akufanele asetshenziswe ekukhanyeni kwemvelo okukhanyayo. Iqiniso liwukuthi ukukhanya okwesibhakabhaka kunomthelela ekubunjweni kwe-peroxide enobuthi ku-retina kanye ne-lens, okubangela uketshezi lokuphendula kwezinto eziphilayo eziholela ekumpumputhe emva kweminyaka embalwa, futhi ngaphezu kwalokho kwandisa ukuphazamiseka okubukwayo. Kungcono ukugqoka izibuko ezinjalo ekukhanyeni kwemini. Izibuko ze-pink ne-orange ziholela ekuphazamiseni umbono, zingabangela ukucasuka, ukwesaba. "Akumangalisi ukuthi bathi:" ubone izwe elibomvu. Lesi sichazamazwi sinomqondo ojulile we-psychophysiological. Indawo ekhethekile kulo mkhakha igcinwe izibuko-ama-chameleons. Lena enye yezinhlobo ezinhle kakhulu kokubili ukugqoka kwangaphandle nokusetshenziswa kwangaphakathi. Njengomthetho, ama-chameleon akhiwa ngeglasi le-quartz ngokufaka ama-photochromes akhethekile, okukhanya okukhanyayo. Izibuko ezinjalo ngokwazo ziyakwazi ukulungisa izinga lokukhanya elifika esweni lakho. Lokhu kuyona engcono kunazo zonke kubantu abanamehlo ampofu.
Futhi kuthiwani uma ...
Uma ugqoke izibuko ezinama-ukhwaliti amakhwalithi aphansi aphuthelwa yi-ultraviolet, umuntu ukhohlisa amehlo akhe nobuchopho, "emtshela ukuthi umfundi kudingeka adwebe, njengoba kukhanya kwelanga, futhi yonke i-ultraviolet flux ingena ku-retina. Imiphumela yalokhu ukulimala kokukhanya kubonakala, njengomthetho, eminyakeni eminingana kamuva: ukukhula kwesifo somzimba kanye nokukhubazeka kwe-macular, okuholela ekulahlekelweni okuncane kokukwazi ukufunda: indawo epholile imbala ivela phambi kweso.
Ngekhwalithi
Ngeshwa, ezikhathini zamalebula zethu azikwazi ukuthembeka njalo kumalebula abonisa izici zokukhanya zezibuko. Kunconywa ukuthenga izibuko ezingosini ezinkulu zezokwelapha ze-optics: ngeke zengozini yabo futhi ngakho-ke kukhona isiqinisekiso esihlobene nesiqiniseko sokuthi sinokwethenjelwa. Uma uthenga izibuko, cela umthengisi ngesitifiketi somkhiqizo. Uma ungabaza, hlola izindawo ezikhanyayo zezibuko, ukubonakala kwazo kwe-ultraviolet kwikhompyutha ye-lens - idivayisi enjalo ifakwe noma iyiphi i-salon yesimanje ye-optics. Yiqiniso, uma ukhetha kuyadingeka ukuba unake intengo.
