Amalensi noma amalensi okuxhumana?  

Ayini amalensi okuxhumana, aziwa kakhulu ngokuthi "amalensi"? Esikhathini esedlule, ama-lens aqinile ayevame kakhulu, afaneleka kangcono igama elithi "ingilazi", kodwa awasetshenziswa kakhulu namuhla. Ngakho igama elithi "contact lens" liyi-anachronistic, ngoba amalensi okuxhumana athambile anamuhla awahlangene nezibuko noma ngisho nepulasitiki. Lawa amaphedi athambile, anamanzi e-silicone e-hydrogel aguquguqukayo futhi avumelana nokuma kweso. Akukho ukukhathazeka ukuthi bazolimaza i-cornea, nakuba ukufakwa okungalungile noma ukugqoka ama-lens oxhumana nabo kungaholela ekucasukeni kwamehlo noma ukuvuvukala. Kubaluleke nakakhulu ukwazi ukuthi ungawagqoka kanjani kahle, uwakhumule futhi uwahlanze amalensi okuxhumana.

Ngaphambi kokukhetha ama-lens afanele, udinga ukucabangela ukuthi ufuna ukuwagqoka kangaki futhi isikhathi esingakanani? Ingabe uzozisebenzisa ngezikhathi ezithile kuphela, njengalapho uzivocavoca, amaphathi, uhambo? Ingabe ufuna ukuzisebenzisa njalo? Ingabe ukhetha amalensi alula, angenambala noma amalensi anombala ashintsha ukubona kwakho? Qaphela - Kungakhathaliseki ukuthi uzogqoka amalensi ngaso sonke isikhathi noma ngezikhathi ezithile, kufanele uhlale unepeya yezibuko okungenani eyodwa esandleni. Kunezikhathi lapho, nganoma yisiphi isizathu, awukwazi ukufaka amalensi, bese izibuko ziwukuphela kwendlela yokubona kahle. 

Kungani ngidinga amalensi okuxhumana futhi ngizowagqoka kangaki?  

Impendulo yalo mbuzo incike ekukhethweni kohlobo olufanele lwamalensi. Ngokusekelwe kulo, ungacabangela uhlobo olufanele lwamalensi - usuku olulodwa, amasonto amabili, ngenyanga noma ngekota, ngoba okwamanje isigaba esithandwa kakhulu lapho izinhlobo zamalensi zihlukaniswa khona yisikhathi sokusetshenziswa kwazo. Amalensi ansuku zonke, njengoba negama lisho, angagqokwa usuku olulodwa kuphela bese ewalahla. Azidingi uketshezi olunakekelwayo. Amalensi amaviki amabili, nyanga zonke, noma ama-quarterly angasetshenziselwa inani lesikhathi elishiwo usuku ngalunye. Ebusuku, kufanele zisuswe, zihlanzwe futhi zifakwe ku-lens uketshezi olukhethekile. Uma uhlose ukugqoka amalensi okuxhumana ngezikhathi ezithile kodwa ugqoke izibuko ngaso sonke isikhathi, khetha amalensi alahlwayo. Athengiswa ngamaphakethe ezingcezu ezingu-30 noma iziphindaphinda zamashumi amathathu (isb. 90, 180, 270 izingcezu). Uma ufuna ukugqoka amalensi okuxhumana nsuku zonke, ukonga kakhulu ukugqoka amalensi njalo ngemva kweviki, inyanga, noma ikota. Atholakala ngamaphakethe amancane amabili, amathathu noma ayisithupha. Uma usebenzisa amalensi akho isikhathi eside, udinga ukunaka kakhudlwana ekuwahlanzeni nasekuwabulaleni amagciwane, njengoba amadiphozithi amaprotheni akheka kumalensi futhi amagciwane angaphindaphindeka. 

Ukukhethwa kwama-contact lens kuyimpoqo ku-ophthalmologist noma udokotela wamehlo  

Lapho ukhetha amalensi ansuku zonke noma esikhathi eside, naka imingcele elandelayo yamalensi: usayizi nohlobo lwesici esibonakalayo alilungisayo (inani lama-diopters ngokuhlanganisa noma kokususa, amalensi e-toric ama-astigmatist) ububanzi nokugoba i-lens enikeziwe. Ububanzi nokugobile kunquma ukuma nosayizi wenhlamvu yeso lapho ilensi ingena khona. Ububanzi belensi busuka ku-12 kuye ku-17 mm (imvamisa cishe bungu-14 mm), ukugoba kusuka ku-8,3 kuye ku-9,5 (imvamisa ku-8,6). Uma liphansi inani lokugoba, iso "elincane" noma "elipholile" ilensi izolingana.

Yiqiniso, ngenxa yokuthamba kwe-hydrogel, ama-lens amaningi afanele ukubunjwa kwamehlo ahlukene. Kodwa-ke, ukukhetha ilensi encane kakhulu kungabangela ingcindezi ebholeni leso, kanti ilensi exege kakhulu ingakwazi “ukuntanta” phezu kweso futhi inyakaze lapho isigqokile. Lokhu kuvame ukuholela ekucasukeni kwamehlo, futhi ukugqokwa isikhathi eside kwamalensi angawafaneleki kahle kungaholela ekuvuvukeni okukhulu kweso. Ngakho-ke, ukuze ukhethe kahle imingcele yama-lens, i-ophthalmologist noma i-optometrist kufanele iwakhethe. 

Izitolo eziningi zamehlo, ezinkulu nezincane, zinikeza izinsiza zokufaka amalensi, ngokuvamile ezihlanganisa ukuvakasha okubili ngezinsuku ezimbalwa ngokuhlukana. Izindleko zesevisi enjalo zihlanganisa ukuhlolwa kokukhubazeka kwamehlo, ukukalwa kwemingcele yeso, isethi yamalensi okuhlola kanye nemiyalelo yokuwagqoka, ukuwakhipha kanye nokuwanakekela. Ekuvakasheni kokuqala, uchwepheshe uzohlola emshinini okhethekile ukuthi ama-lens alingana kahle namehlo ethu, kungakhathaliseki ukuthi makhulu kakhulu noma mancane kakhulu, futhi uzokufundisa indlela yokugqoka nokukhipha ama-lens. Ekuvakasheleni kwakho okulandelayo ezinsukwini ezimbalwa, uzosazisa uma ukhululekile ngamalensi okuhlola futhi ubona kahle. Uma kunjalo, bakhethwe kahle futhi le modeli ethile ikufanele kakhulu. Ngaphambi kokuzama imodeli yelensi ehlukile, kufanele futhi uvakashele udokotela wamehlo noma i-optomist ukuze ahlole ukuthi ingabe ikulungele yini. 

Ukunakekelwa kwansuku zonke kwelensi yokuxhumana 

Amehlo azwela kakhulu ekucasukeni nasekuthelelekeni, ngakho-ke udinga ukunakekela ukuhlanzeka kwamalensi akho okuxhumana. Izifo zamehlo kanye ne-conjunctivitis azijabulisi kakhulu futhi ngokuvamile kunzima ukwelapha, futhi ezimeni ezithuthuke kakhulu zingaholela ebumpumputhe. Ngakho-ke uwanakekela kanjani ama-contact lens akho ukuze ungangenwa amagciwane? Okokuqala, ngaphambi kokuthi ngamunye athinte amalensi, kufanele ugeze kahle izandla zakho ngensipho namanzi, ugeze kahle futhi wome ngethawula elihlanzekile - okungcono elilahlwayo. Kuphela ngemva kwalokho ungaqala noma yiziphi izenzo ngamalensi. Azikho izinkinga ngezinkinga zansuku zonke - nsuku zonke sikhipha isitimu esisha esiyinyumba ephaketheni, bese sisiphonsa kudoti kusihlwa. Amalensi aphuma kabili ngesonto, nyanga zonke kanye nangekota kumele awashwe futhi abulawe amagciwane nsuku zonke ngoketshezi olukhethekile kusetshenziswa ikesi lelensi. Uketshezi olusebenza kakhulu oludume kakhulu lusetshenziselwa ukugeza, ukuhlanza, ukubulala amagciwane nokugcina amalensi. Kwesinye isikhathi aqukethe nezinto ezithambisa futhi ezithambisa amehlo, kanti uketshezi luvamise ukufaka isitsha sokugcina amalensi. Nazi izinyathelo ongazithatha ukuze ususe amalensi akho ebusuku futhi uwavule futhi ekuseni:

• geza futhi womise izandla zakho,
• lungisa ibhokisi bese uligcwalisa ngoketshezi olusha,
• susa i-lens (sihlala siqala ngeyodwa efanayo, isibonelo, kwesobunxele. Ngenxa yalokhu, ngeke senze iphutha, elibalulekile uma sinezinkinga ezihlukahlukene zombono emehlweni womabili) futhi sibeke entendeni yesandla isandla sakho,
• gcoba amaconsi ambalwa oketshezi bese uhlikihla ilensi esandleni sakho ngomunwe wakho imizuzwana embalwa,
• hlambulula i-lens kahle ngoketshezi bese uyibeka esitsheni,
• phinda izinyathelo ngelensi yesibili,
• vala isitsha bese ushiya ama-lens liquid ubusuku bonke,

Qaphela - Kufanele ngaso sonke isikhathi usebenzise uketshezi olukhethekile ekunakekeleni nasekubulaleni amagciwane amalensi. Isixazululo esivamile saline akwanele - udinga umuthi ozonciphisa ukukhula kwamagciwane kanye ne-protozoa kumalensi. Ngaso sonke isikhathi sebenzisa umthamo omusha we-liquid - kuphela lapho kuzosebenza kahle! 

Kungani kufanele ngisuse ama-lens ebusuku? 

Abaningi bangase bazibuze ukuthi kungani kubaluleke kakhulu ukususa ama-lens ebusuku? Kwenzekani uma ngilala ngigqoke amalensi okuxhumana? Uma lokhu kwenzeka kanye - cishe akukho lutho oluzokwenzeka, ngaphandle kokungakhululeki kanye nomuzwa "wamehlo omile" lapho uvuka. Kodwa-ke, ukulala njalo kuma-lens kuholela eqinisweni lokuthi ubuso beso bugcwele umoya-mpilo kahle futhi bome (ama-lens ahlala emunca umswakama, futhi ukukhiqizwa kwezinyembezi kuphansi ebusuku kunasemini). Yebo, akhona amalensi emakethe okugqoka unomphela - imini nobusuku, anomoya omuhle kakhulu wokungena komoyampilo. Kodwa-ke, ngisho nasezimweni zabo, kufanelekile ukuwakhipha ngezikhathi ezithile ukuze ukhiphe amagciwane futhi unike amehlo akho ukuphumula. 

Kumalensi ansuku zonke, lokhu kubaluleke kakhulu. I-cornea yeso ayinayo i-vascularized futhi ithola umoya-mpilo ngokuqondile emoyeni. I-hypoxia yesikhathi eside ye-cornea ingaholela ekwakhekeni kwemithambo yegazi emisha ku-cornea njengoba umzimba uzama ukunikeza iso ngenani elifanele lomoya-mpilo - igazi - ngazo zonke izindleko. Khona-ke sizoba njalo ngamehlo "egazi", futhi lokhu, cishe, akekho ofuna. 

Izeluleko ezisebenzayo zabasebenzisa lens yokuxhumana

Izohwamuka ngokuphelele, ngakho-ke akufanele ukhathazeke ngezinsalela eziyingozi, futhi kuze kube yileso sikhathi izobulala amabhaktheriya namanye amagciwane. Khumbula ukusebenzisa isitsha kuphela lapho somile ngokuphelele ukuze ugweme ukuthola utshwala emehlweni akho. Ungalokothi usebenzise ezinye izinhlobo zotshwala (ezifana ne-salicylic noma utshwala obungcolile).
