Usoyikiso kunye nefuthe lokugcinwa kwesigulana, ukwaliwa, kunye nokunikezelwa kwe-intanethi kulawula ukucinga kwethu malunga neelensi zoqhagamshelwano.Nokuba kuninzi okwenziwa ngokutsha, imarike ihleli imile.Indawo enye omawujonge kuyo ukukunceda ukhulise ishishini lakho lelensi zoqhagamshelwano kwaye ugcine izigulana zakho zibonelela ngeemveliso ezilungiselelwe wena.Kwabanye abachwephesha, ukuzithemba, amava anqongopheleyo, iingxaki zezixhobo, okanye ukunqongophala kokugxila kuqeqesho lwe-optics kunokuba ngumqobo ekufakeni iilensi zesiko.Kwakhona kunokuqondwa phosakeleyo ukuba badla ixesha kwaye abawufanelanga umzamo.Nangona kunjalo, ukunxiba iilensi zesiko kunokuphucula umfanekiso wakho wobuchwephesha kwaye kwandise ukwaneliseka komsebenzi.
IiLensi zoQhagamshelwano ezininzi
Kulabo abanomdla ekuqaliseni ukugqoka iilensi eziqhelekileyo okanye ukubuyela kubo njengendlela yokukhetha isigulane, inkqubo ingaba ngumngeni.Esi sikhokelo samanyathelo asixhenxe siya kukunceda uphumelele.
Ixesha lokuqala sasicinga ukuba ukufaka iilensi ezingekho mgangathweni kungenxa yolungiso oluphezulu, nokuba lungqukuva okanye lungqukuva, kodwa yinxalenye yamathuba.
Udidi lwe-presbyopia kunye ne-astigmatism luyaqhubeka lukhula, kwaye nangona ukulungiswa kwabo kungenakuba phezulu kakhulu kuyo nayiphi na i-meridian, ukhetho lwabo luhlala lulinganiselwe ngenxa yenani elikhulu lamanqaku afunekayo ukuququzelela ukuphumelela kwe-lens ukunxiba.Enyanisweni, iilensi eziveliswe ngobuninzi zisenokungafikeleli iimfuno zazo.
Udidi olulandelayo ngabo basebenzisi ngoku basebenzisa iilensi zoqhagamshelwano ezininzi kodwa abanelisekanga ngokupheleleyo ngabo, kubo “umbono osebenzayo” usenokungonelanga kwaye ukhetho lobuqu lunokuba ngcono.Ke abanye abantu bafumana i-ghosting okanye i-halos, ngoko uyilo olunobunzulu obongezelelweyo bentsimi bunokufuneka ukulungisa le miba.
Okokugqibela, sineqela lezigulane ezihlala zingahoywa ezazinezilungiso ezilula eziye zakhokelela ekubeni zifakelwe iimveliso ezikumgangatho ongekho kwishelufu kodwa zincinci okanye zikhulu kune-avareji ye-corneas okanye i-corneas yazo ibe flat.okanye enkulu.Imeko eqhelekileyo ipholile.
Qala ngovavanyo lwamva nje lwe-dioptric, uvavanyo lwe-corneal, kunye nemilinganiselo ye-biometric ye-k-reading kunye ne-HVID (I-Horizontal Visible Iris Diameter), njengesiqhelo sokufaka iilensi zoqhagamshelwano.Le milinganiselo iya kunceda ukugqiba ukuba zeziphi izigulane ezifanele ukunxiba iilensi eziqhelekileyo.
IiLensi zoQhagamshelwano ezininzi
Iingcali zeTopographer zibonelela ngolwazi oluthe kratya, olufana nenqanaba lokucaba malunga ne-cornea (eccentricity), kodwa kwabo bangenayo, imithetho ye-keratometer kunye ne-PD (umgama we-interpupillary) yanele kwi-HVID.Ukuba sifuna ukufaka iiglasi ezininzi, ngoko ulawulo lwamehlo luyafuneka.
Kufuneka siqwalasele ukuba yeyiphi imathiriyeli eyona ifanelekileyo kwisigulane kunye neendlela.Ngaphandle kwezigulane ezinamehlo omileyo, izigulane ezifuna ukunxitywa kwexeshana zinokuthi zihanjiswe kakuhle nge-hydrogel, ngelixa ezo zifuna ukunxiba ixesha elide zinokuzuza kwi-silicone hydrogels.Kwakhona, qwalasela ukukhetha izixhobo zezigulane ze-presbyopic ezithandwa kakhulu kwiimpawu zamehlo ezomileyo.
Ngeli xesha, kufuneka sibe nalo lonke ulwazi esiludingayo ukuze si-odole i-lens.Nceda ubhekisele kwisikhokelo sofakelo somenzi, esinokuxhaswa ngekhaltyhuleyitha ye-intanethi.Ukuba awuqinisekanga, banokuba nenkonzo yenkxaso yobugcisa enokukunceda ukhethe imathiriyeli kunye neenkcukacha.
Lindela ubuncinci imizuzu engama-20 emva kokunikela ukuze ilensi izinze kwaye emva koko uvavanye ukufaneleka.I-over-refraction kufuneka yenziwe kuphela xa i-ophthalmologist yanelisekile ngendlela i-lens ingena ngayo iliso.Ukuba ukufaneleka kunye nokubona kuyanelisa, qhubeka kunye nexesha elifanelekileyo lokufaneleka.
Kwimeko yokunganeliseki, ubuhle beelensi eziqhelekileyo kuthetha ukuba sinokuzilungisa kwaye sifumane iziphumo ezilungileyo.Ukunyakaza okugqithiseleyo kunokuncitshiswa ngokunyusa ububanzi kunye / okanye ukunciphisa i-curvature yesiseko, ngelixa ukunyakaza okunganeleyo kunokunciphisa ngokunciphisa ububanzi kunye / okanye ukwandisa i-curvature yesiseko.
Njengesikhokelo, ukuba i-lens ijikelezwe ngaphezu kwee-degrees ze-20 kwaye i-hyperreflexia iphezulu kakhulu kunokuba ilindeleke ngokuqhelekileyo, okanye i-visual acuity (VA) ayiphucukanga nge-hyperreflexia, ngoko ukulungelelaniswa akunakwenzeka ukuba kube yinto efanelekileyo kwaye kuya kufuneka siphinde sihlolisise. igophe elisisiseko kunye nobubanzi.
Ukuba ufumana iziphumo ebezingalindelekanga, ezinje nge-VA engaphucukanga ngenxa yokuchaswa ngokugqithisileyo, kwaye awuyazi indlela yokuqhuba, umenzi uya kukuvuyela ukukunceda.
Xa wena kunye nesigulane ninelisekile, qhubekani neelensi zemithi, ngokufanelekileyo ubandakanya isigulane kwisicwangciso sokhathalelo lwangoku.Kwabo bangakwaziyo ukubonelela okanye ukubhalisa kwiprogram enjalo, ukubabiza rhoqo emva kweenyanga ezintathu ukubakhumbuza ngomyalelo kuya kuqinisekisa ukuthotyelwa kakuhle kunye nokunciphisa iingxaki kunye nokuyeka emva koko.
