Yintoni Umahluko phakathi kweeglasi kunye neMiqathango yoQhagamshelwano?
Iilensi zoqhagamshelwano kunye nemigqaliselo yeglasi yohlukile kuba iiglasi kunye neelensi zoqhagamshelwano zibekwe ngokwahlukileyo kwiliso lakho. Iiglasi zihlala malunga neemilimitha ezili-12 ukusuka kwiso, ngelixa abafowunelwa bahlala ngqo kumphezulu wamehlo. Ezi milimitha ezili-12 zenza umehluko wehlabathi kwaye zinokutshintsha ngokuphawulekayo imimiselo phakathi kwezi zimbini.
Kwakhona, imiyalelo ye-lens yoqhagamshelwano ifuna iinkcukacha ezingaphezulu kuneeglasi. Ezi ziquka:
1. IDayamitha yeLens: Idayamitha yelensi ichaza ubungakanani belensi njengoko kulinganiswa iliso lakho. Ububanzi bonxibelelwano oluthambileyo luvela kwi-13.5 ukuya kwi-14.5 millimeters, kwaye uluhlu lwabafowunelwa olukhuni luvela kwi-8.5 ukuya kwi-9.5 millimeters. Ezi idayamitha azilingani-zonke, yiyo loo nto zifuna uvavanyo lokudibanisa umfowunelwa.
2. I-Base Curve: I-base curve yi-curvature ye-lens yangasemva kwaye inqunywe yimilo ye-cornea yakho. Eli jiko limisela ukulingana kwelensi eqinisekisa ukuba ihlala kwindawo.
3. I-Lens Brand: Ngokungafaniyo neeglasi, imiyalelo yoqhagamshelwano nayo ibandakanya uphawu oluthile lweelensi.
Zithetha ntoni izifinyezo kwiMimiselo?
Siye sagubungela amacandelo awongezelelweyo emigqaliselo yoqhagamshelwano. Nangona kunjalo, unokuqaphela izifinyezo ezingaqhelekanga kwilensi yakho yoqhagamshelwano kunye nemigqaliselo yeglasi. Masijonge ukuba ezi zishunqulelo zithetha ukuthini ukuze ube nokuyiqonda ngcono imimiselo yakho kunye nomahluko phakathi kwayo.
1. I-OD okanye i-Oculus Dexter: Oku kubhekisela nje kwiso lasekunene. Kukwayinto eqhelekileyo ukubona "RE".
2. I-OS okanye i-Oculus Sinister: Eli gama libhekisela kwiso lasekhohlo. Kuqhelekile ukubona "LE".
3. OU okanye i-Oculus Uterque: Oku kubhekisa kuwo omabini amehlo.
4. Minus Sign okanye (-): Ibonisa ukubona kufutshane.
5. Umqondiso Wokudibanisa okanye (+): Ubonisa ukubona kude.
6. I-CYL okanye i-Cylinder: Ichaza ubungakanani bamandla afunekayo ukulungisa i-astigmatism.
Ngaba ungawuguqulela ummiselo weeglasi kubafowunelwa?
Ngoku ufunde umahluko phakathi koqhagamshelwano kunye nomyalelo weglasi, usenokuba uyazibuza ukuba ingaba umyalelo weglasi ungaguqulwa ube ngummiselo welensi yoqhagamshelwano. Impendulo elula kule nto ithi "hayi". Ngaphandle kweetshathi kunye noguqulo oluthunyelwe kwi-intanethi, umyalelo woqhagamshelwano ufuna ukuxilongwa kwamehlo kunye nelensi yoqhagamshelwano efanele ukulawulwa ngugqirha wamehlo onelayisensi.
Izinto eziluncedo kunye neeNgeniso zokuNxitywa iindondo zamehlo
1. Iindondo zamehlo zibonelela ngokulula; zisuswa ngokulula xa kuyimfuneko.
Iiglasi zibonelela ngononophelo oluphantsi lokhetho lwabantu abafuna kuphela ukulungiswa kokubona 2. imisebenzi ethile, njengokufunda, ukuqhuba okanye ukusebenzisa izixhobo zedijithali.
Ukunxiba iindondo zamehlo kuthintela abantu ukuba bangawachukumisi amehlo, oko kunciphisa ingozi yokosulelwa kunye nokucaphuka.
3. Iiglasi zikhusela amehlo kwinkunkuma kunye nezinto, njengamasuntswana othuli, umoya kunye nemvula.
4. Iiglasi zinokukhusela kwimitha yelanga yeultraviolet, ngokuxhomekeke kuhlobo lwelensi (umz., iiglasi zelanga okanye iilensi ezisebenza ngokukhanya).
5. Iiglasi ezigcinwe kakuhle zingahlala iminyaka ngaphambi kokuba zifune ukutshintshwa (ukuba umyalelo wakho awutshintshi).
Yintoni omele uyilindele ngexesha loviwo lweLens yoQhagamshelwano?
Olu viwo lubandakanya ingxoxo malunga nendlela yakho yokuphila iyonke kunye novavanyo lwamehlo. Ugqirha wakho wamehlo uya kuvavanya i-curvature ye-cornea yakho ukuqinisekisa ukuba iilensi zakho ezintsha zilingana kakuhle. Ubungakanani bomfundi wakho bunceda ukujonga ubungakanani belensi yakho.
Ukuba ujonge iiglasi okanye incwadi kagqirha yelensi yoqhagamshelwano, ugqirha wakho wamehlo unokukunceda. Banokuvavanya impilo yamehlo akho kunye nombono kwaye banqume olona khetho lusebenzayo.
