Kwiofisi
Ubuchwephesha bekhompyutheni banamhlanje bomelelwe ngokucacileyo ebomini bethu. Yaye umthwalo ojongene nawo wanda ngeli xesha ngamaxesha amaninzi. Abasebenzisi abaninzi bekhompyutheni bakhononda ngokukhathala kwamehlo, ubomvu babo, ubomile, umbono obonakele, iintloko. Zonke ezi zibonakaliso ze-computer syndrome. Izikhalazo eziqhelekileyo malunga nesimo somzimba zivela kubathandi be-lens. Ngokusetyenziswa kwexesha elide, i-frequency of blinking decreases, eyenza iliso kunye ne-lens yokudibanisa yomile. Kukho uvakalelo olungathandekiyo, umnqweno wokususa ii-lens zokudibanisa kwaye ubuyele ngonaphakade kwiindawo. Olunye uncedo lunokunikezwa ngamaconsi athile okucoca. Kuyavela, ukugqoka iiglasi kwiofisi kunengqiqo. Ukuba ufumana uxinzelelo olunzima kwibhuloho yempumlo kunye nokukhathala kwamehlo, unokususa iiglasi, uncike kwisihlalo sakho kwaye uvumele amehlo akho aphumle, okungeke kusebenze ukuba unxibelelwano lwamalensi. Oososayensi baseMelika baseWashington bahlanganyela ekuphuhliseni iilensi ezine-microcircuits ezifakwe ngaphakathi. Olu gcwaliso luya kuvumela iilensi zokunxibelelana ukuba zikhulise izinto kwaye zibonise iinkcukacha ezahlukeneyo malunga nabo kwi lensi. Kwixesha elizayo elizayo i-novelty iya kuvela kwiivenkile. Ngendlela, kuxhomekeke kwiiglasi okanye i-lens ayiyenzeki! Yonke le nto iphosakeleyo!
Ukuthuthuzela
Kwaye emva kweglasi, kwaye emva kwama-lens kufuna ukunakekelwa okufanelekileyo. Okukugqibela kufuneka kugcinwe kwisitya esikhethekileyo, ngasinye sichitshintsha isisombululo. Iiglasi kufuneka zicimiwe, ngokuphindaphindiweyo ukwenzela ukuba zingenalo inkunkuma kunye namacangco phezu kwabo, kwaye zibone ukuba iiglasi ziye zanyulwa - kule meko, iilensi zinenzuzo ecacileyo. Kukho iintlobo ezahlukeneyo: olunye usuku, iiveki ezimbini, isiqingatha sonyaka. Kuyinto elula kakhulu kusasa, kunye nokufumana, umzekelo, we-multivitamin complex, ukufumana i-lens kwi-blister kwaye uyifake, kwaye ngokuhlwa ukukhupha nokulahla. Ngokungafani neelensi zokusebenzisa ixesha elide, akukho mfuneko yokuzigcina ezigulini ezikhethekileyo, ukufumana izicwangciso. Ukongeza, emva kwexesha, ii-lens ezigqoke ixesha elide zilahlekelwa ezinye iipropthi zazo, zihlatywe, apho kuthiwa i-detritus-mucus ihlangene kunye neeseli ezifile zamehlo eziye zahlanjululwa, kwaye azikho zonke izicombululo nazo ezinokuphumelela. Oku kwandisa ingozi yokusuleleka. Kungcono ukusebenzisa iilensi ezilahlayo.
Impilo
Ukuba unobanda, kukulungele ukusebenzisa iiglasi, ngenxa yezifo zokuphefumula, kukho ukukhukhumeza okusebenzayo kwe-conjunctiva kunye ne-epithelium ye-cornea ngenxa yokukhwehlela okuqinileyo kunye neempumlo. Kwakhona, iiglasi ziyimfuneko yokudibanisa (isifo seso esithathelwanayo), ukwenzela ukuba ukutshabalalisa ngokugqithiseleyo kushiye amehlo akho, kwaye ungasenayo igciwane.
Ngomfanekiso
Ngokuqinisekileyo, ngoncedo lweglasi ungatshintsha umfanekiso, ube yintombi yebhizinisi, unobhala onobuhle okanye utitshala oqinileyo. Kodwa ngokufanayo, ngokungafani nama-lens, abakwazi ukugxininisa ubuhle bemvelo. Ukuba unamehlo aluhlaza, unako ukwenza ukuba luhlaza okanye lubomvu. "Ipulazi elimnyama" liso, ngokuchaseneyo, linokwenziwa lula. Ngenye indlela, faka nje udibanisa umbala wakho wendalo. Ukwenza oku, kukho iilensi zokudibanisa ezifihlakeleyo ezingakwazi ukufihla iimpazamo ezithile ezibonakalayo kunye neempembelelo ezibonakalayo kwamehlo, kuxhomekeke kumfanekiso okhethwe ngumguli. Abayi kuguqula umbala wamehlo amnyama okanye avulekileyo, kodwa baya kwenza ukukhanya kubonakale kwaye bongeze ukukhanya. Impembelelo yezitho zecala yee-lens mayingabonakali. Ukuba ukwesaba ukugqoka ii-lensi zokudibanisa ngenxa yokuba ungafuni ukubona i-bluhlaza okanye i-pink, cwaka: le nto ayiyi kwenzeka. Ukususela ekuveliseni iilensi zambala, iteknoloji yemveliso yayo ishintshile kakhulu. Ii-lens zanamhlanje, kunye ne-iris eprintiweyo kubo, zinika umfanekiso wemvelo, ekubeni iilensi ezinemibala zinendawo ebonakalayo ebonakalayo apho ukukhanya kungena khona. Ukuba i-lens ityhidiweyo (imbala epheleleyo eluhlaza okwesibhakabhaka, eluhlaza okwesibhakabhaka, eluhlaza okanye eluhlaza), ngoko umgca we-polymeric umbala awudluli kwi-20%, engatshintshanga ingcamango yokubala ngemibala enjalo. Kodwa kungekhona nje umbala wamehlo onokutshintsha ii-lens zoqhagamshelwano. Bangakujika zibe zombie okanye umntu ongaqhelekanga. Iilensi ze-Carnival ezifana nokuphosa kunye nokuzonwabisa kunokukwenza oku. Oku kuncedo kakhulu kumacandelo, apho ungabonakala phambi kwabahlobo bakho ngendlela entsha engalindelekanga. Musa ukugqoka ii-lens ezinemibala engaphezu kweeyure ezili-12: ngenxa ye-hue ayinayo i-oksijeni ephezulu yokufaneleka, kunye nama-lens afana ne-crazy - ngaphezu kwama-4-5 iiyure. Ukufaneleka kwazo kwe-oksijini kuyincinci kakhulu, ayihloselwe ukugqoba ngokusisigxina ngenjongo yokulungiswa kombono. Isalathisi sitholakale, kubandakanywa kwindawo ebonakalayo ye-lens, eyona nto ibangela ukuba imbono ebonakalayo ibonakale. Ngoko banxibe ngokungabonakali kangangoko kunokwenzeka, kweso sihlandlo.
Ukuzonwabisa okusebenzayo
Ukuba sithetha ngokuphumla, ikakhulukazi elunxwemeni, ukhetho luyabonakala - iilensi. Abayi kubonakala xa bedlala i-volleyball yaselwandle, kunye nabo unokuzibona zonke izinto ezihle zehlabathi elingaphantsi kwamanzi, ukuba unxibe imaski ekhethekileyo yokubhukuda. Nangona kunjalo, ukuba ungumlandeli wezibuko, unokwenza umyalelo okhethekileyo, ii-anatomical forms. Ziqineke ngakumbi kwaye zingaboni kwijoni ngokunyakaza okusebenzayo, kwaye unako ukugcina "iimfihlelo" zezinzulu, nangaphandle kokuzinikela. Kuye kwaphuhliswa iziglasi ezikhethekileyo zokubhukuda kunye ne-diopters. Ukususela ekuzalweni kwama-lens, kukho ezininzi iingxolo malunga nabo.
Iingoma malunga nama-lens oqhagamshelwano:
1.Ukuba mna okanye ugqirha akakwazi ukubeka i-lens yocingo, andinakuze ndiwagqoke. Oku akunjalo. Kufuneka ube nesineke, ukulahla ukwesaba uphinde uzame ukubeka iilensi phambi kogqirha. Emva kwemizamo emininzi ephumelelayo, ukubeka ii-lens ukuyeka ukubonakala kunzima, iso liya kusetshenziselwa ukusetyenziswa. Ngamanye amaxesha isigulane sakhe siba ngcono ukubeka i-lens, kodwa ugqirha ngokuqhelekileyo unceda ngokuqondisa isandla sesigulane kunye ne-lens kwiso.
2.Qinisekisa iilensi ziyingozi kwiso, kuba zonke izihlandlo ozibeka kuzo, uzilimaza i-cornea. Akunjalo. Kukholelwa ukuba izakhiwo ze-microtraumatic zamehlo xa zembethe i-lens zenzeka, kodwa akudingekile ukuba zikhulume ngazo, ngokuchanekileyo, malunga naso nayiphi na into ebalulekileyo yeklinikhi xa usebenzisa iilensi kwizinto zanamhlanje. Iilensi zamanxeba zangoku azilimazi iso, ziyindlela efanelekileyo kwaye iphephile yokulungiswa kombono.
3.Qhagamshelana nama-lens kunokukhokelela ekusulelekeni kunye nezifo zamehlo. Ewe, kunokwenzeka, ukuba ii-microorganisms zingena kwijoni nge-lens. Iimbangela zokubonakala kweentlobo ezincinci kwi-lens zidibaniswa nokungahlanjululwa kakubi, ukungcoliswa kwesitya, ukugqithiswa kwe-lens. Ukunciphisa ukusuleleka kwintsholongwane, kungcono ukusebenzisa i-CL yosuku olulodwa: kulo mzekelo, ngalunye ixesha i-lens ecocekileyo neyatshatywayo ifakwa kwijiso, kwaye akukho zicwangciso kunye nezikhonkwane - eziphambili kwimithombo yesifo.
4.Ukuba unxibe iilensi, kufuneka usebenzise izimonyo ezikhethekileyo zokubhabisa. Ewe, oku kunjalo, xa ugqoke iilensi kufuneka usebenzise i-special certified (ngokuqhelekileyo kwiphakheji ibhaliwe "avunywe yi-ophthalmologists") kunye ne-hypoallergenic cosmetics. Akucebisi ukuba usebenzise i-mascara enezongezo ezikhethekileyo, ezifana neengcambu okanye iinwele ze-mink: ziyaqhekeka kwaye, ukufumana iilensi, kubangele ukuvakalelwa.
5. Andiyidingi iilensi zokudibanisa, kuba ndisebenzisa iiglasi kuphela xa ndisebenza kwikhompyutheni kwaye ndihlala evili lomoto. Le nto ingalunganga. Ukuba ufuna iiglasi ngenxa yemisebenzi ethile, kuthetha ukuba unamahlwempu. Kwaye kufuneka idinga ukulungiswa rhoqo. Ukungabikho kwalokhu kubangela ukunyuka okongeziweyo kwamehlo nangengqondo, okubangela ukunyuka kombono. Ukongezelela, ukusetyenziswa kwamalensi ekudibanisa xa uqhuba imoto ayicinci kwintsimi yombono, akukho zibophelelo zangasemva, akukho nto iyancitshiswa ezintweni ngenxa yokuba i-lens yinkqubo enye ye-optical eye eyeball.
6. Iilensi zesizukulwana esitsha zikhuselekile kwi-ray ye-UV, ngoko ke izikhanyiso zelanga azikho mfuneko. Le ngqungquthela. Iimvani zelanga zifunekayo, kuba i-lens ikhusela kuphela i-cornea kunye neendawo zangaphakathi zeso elangeni. Elinye iliso kunye neelusiki zihlala zivulekile, ngoko kufuneka zikhuselwe ngeiglasi.
Iingongoma ezilikhulu ngaphambili
Akunandaba, umbono wakho uphantsi okanye ulungile - usasafuna ukukhusela amehlo akho elangeni. Into ephambili kukuba ukhethe izibane zokukhanya ezifanelekileyo. Kukho iindlela ezikhethiweyo zokukhetha.
Ngezinga lokukhuselwa kwe-UV
Ubungqina bokukhusela ngokwaneleyo kweziglasi ezivela kwi-ultraviolet zingabhaliswa ngokuthi "UV 400", ebonisa ukuba zikhusela amehlo ukusuka kwimizila engaphezulu kwe-400 nm (oku kukhanya kwe-spectrum ultraviolet 290-380 nm). I-quartz lens (iglasi eqhelekileyo) ivimbela ngokupheleleyo ukungena kweemitha ze-UV, iiglasi eziglasi ezinjalo zinokuthenjwa. Ezi iilensi zinezinye kunye kunye: aziyikutshitshisa kakhulu. Kodwa i-drawback yayo eyona nto iphakamileyo. Okwangoku, iilensi ezenziwe ngezixhobo zepolymeric ziya ziba zithandwa. Xa ukhetha ezi ngqungquthela, jonga ngokukhawuleza ukuthunyelwa kwe-ultraviolet.
Ngezinga lobumnyama babo
Kukho ama-5 e-shading of lens glasses lens (80-100% yokukhanya okudlulileyo - ii-lens ezibonakalayo, 43-80%, 18-43%, 8-18% kunye no-3-8% - i-lenses emnyama kakhulu idlulayo). Ukukhethwa kwebala okanye ngokubhekiselele, izibuko zelanga zixhomekeke apho umntu uya kuzisebenzisa khona. Ngokomzekelo, ukuhamba ezintabeni kunengqiqo ukuthenga iiglasi ezimnyama. Ukuba uya kuphumla ekukhanyeni okuphantsi, ukukhanya ngakumbi. Kwabaninzi abantu, iiglasi ezihamba ngokukhawuleza kwezi-18-43% zifanelekile. - Ezi zibuko zelanga zonke, kwiibhile apho injongo ebhaliweyo ibhaliwe. Kufuneka kukhunjulwe ukuba ububanzi bomlenze we-lens kunciphisa ukuhanjiswa kokukhanya.
Ngokwemilo yesakhelo
Into ebalulekileyo ekukhetheni izibuko yimilo yabo. Oku akuyona nje umcimbi womfanekiso. Iifom zesimo se-anatomical sivumela ukukhuselwa okuthembakalayo ngokuthe ngqo kwi-ultraviolet, kubandakanywa ukukhanya okungahambi ngqo kwamehlo kunye nesikhumba se-conjunctiva. Kodwa kunjalo ukhetho lwefomu yeglasi luzimisele ngokungundoqo. Umzi kunye nesitayela seshishini, umzekelo, "ii-aviators", ukuba ilizwe lihambe okanye lidlale elwandle, zifaneleke ngezemidlalo. Xa ukhetha izibuko, ukubaluleka kubalulekile, ukufika kwayo kwibhulorho yeempumlo, ubude kunye nokuma kweetempile. Ukubekwa kwempumelelo kungabangela intloko.
Ngombala weelensi
Ukukhethwa kweziglasi zemibala kuncike kakhulu kumlinganiselo wesitho. Nangona kunjalo, okokuqala, kuyimfuneko ukunyamekela indlela iifayile zokukhanya eziza kutshintsha ngayo umbono obonakalayo. Ukuphazamiseka okuncinci kweembono kubangelwa iigrey eziluhlaza, eziluhlaza kunye ezimnyama. Umbala ohlaza obala. Ngaphezu koko, iziglasi zangaphambili kunye neziglasi zazisetyenziselwa unyango lwe-glaucoma. Iilensi zeBrown, mhlawumbi, zizona ziphezulu kakhulu kwaye ziphela jikelele: ziqhekeza inxalenye ebalulekileyo yokukhanya okwesibhakabhaka okungabonakaliyo kunye negalelo ekunyuseni ukungafani kwamehlo. I-lens eluhlaza okwesibhakabhaka kunye ne-blue Inyaniso kukuba ukukhanya okwesibhakabhaka kunceda ekwakheni i-peroxide enetyhefu kwi-retina kunye ne-lens, eyenza ukukhangela kwezinto ezinokwenziwa kwezinto eziphilayo eziholela ekuphoseni emva kweminyaka embalwa, kwaye ukongeza ukwandisa ukuphazamiseka okubonakalayo. Kungcono ukunxiba iilazi ezinjalo ekukhanyeni kwemini. Iiglasi ze-pink kunye ne-orange zikhokelela ekuphazamiseni imbono, kunokubangela ukucasuka, ukwesaba. "Akumangalisi bathi:" yibona i-pink in pink. Esi sifanekiso sinentsingiselo enkulu yengqondo. Indawo ekhethekileyo kulo mgca ihlala iiglasi-i-chameleons. Le ngenye yezona ndlela zintle zokubambisa zangaphandle kunye nokusetyenziswa kwangaphakathi. Njengomthetho, i-chameleons zenziwe ngeglasi ye-quartz kunye nokongezwa kwee-photochromes ezikhethekileyo, ezikhanyayo ngokukhanya okukhulu. Ezi zibuko ngokwabo ziyakwazi ukulungelelanisa umgangatho wokukhanya ongena kwilihlo lakho. Oku kuyona khetho oluhle kubantu abanokubukeka kakubi.
Kuthekani ukuba ...
Xa ugqoke iiglasi kunye nama-lens aphezulu alahlekelwa yi-ultraviolet, umntu ukhohlisa iso kunye nengqondo yakhe, "kumxelela ukuba umfundi ufuna ukunyuka, njengokuba kuluhlaza, kwaye yonke i-ultraviolet flux ingena kwi-retina. Imiphumo yale ngozi yokukhanya ibonakala, njengomthetho, kwiminyaka emininzi kamva: i-cataract kunye ne-macular degeneration ukukhula, okukhokelela ekulahlekelweni okukodwa kokukwazi ukufunda: indawo ebomvu ivela phambi kweso.
Ngo mgangatho
Ngelishwa, ngexesha lethu iilebula azikwazi ukuhlala zithembeka kwiilebula ezibonisa iimpawu ezibonakalayo zeglasi. Kucebise ukuthenga iziglasi kwiironi zonyango ezinkulu ze-optics: abayi kubeka ingozi kwi-reputation yabo kwaye ngoko kukho isiqinisekiso esinxulumene nokuthembeka. Xa uthenga iiglasi, cela umdayisi ngesitifiketi somkhiqizo. Ukuba ungathandabuzeki, jonga izinto ezibonakalayo zeglasi, ukubonakala kwazo kwe-ultraviolet kwikhompyutheni yekhompyutheni - eso sixhobo sixhotywe nayiphi na i-salon ye-optics yanamhlanje. Ewe, xa ukhetha kuyimfuneko ukuhlawula ixabiso.
