Ingabe lokhu kuyenzeka nakuwe? Ugqoka izibuko ukuze ufunde iphephandaba. Uma ufuna ukubuka i-TV isikhashana, uyazikhumula bese ugqoka enye. Uma uhamba emgwaqweni, udinga ezinye izibuko ukuze uzibonele kude. Akuyona yini inkinga ukushintsha lezi zibuko? Uthenga enye ngengqondo yakho bese ushiya enye ekhaya. Ngezinye izikhathi uyakhohlwa zombili. Uma nawe ubhekene nale nkinga, amalensi aqhubekayo angaba yisisombululo esifanele kuwe. Namuhla, sizoxoxa ngalokhu ngendlela elula ongayiqonda.
Ziyini lezi ziLensi Eziqhubekayo?
Kalula nje, lezi uhlobo olukhethekile lwezibuko ezinamandla amaningi ngaphakathi kwelensi efanayo . Ngokwezokwelapha, lezi amalensi "ama-Multifocal". Lokho kusho ukuthi ungabona ngokucacile emabangeni ahlukene ngelensi efanayo. Cabanga nje...
- Bheka ngokucophelela: imisebenzi efana nokufunda iphephandaba noma incwadi, ukuhlola ifoni yakho, noma ukufaka intambo enalitini.
- Ukubona ibanga eliphakathi: Kwezinto ezifana nokusebenza kukhompyutha, ukubheka ubuso bomuntu ophambi kwakho etafuleni lesidlo sakusihlwa, nokubuka i-TV.
- Ukubona ibanga: Izinto ezifana nokushayela imoto, ukufunda igama lesitolo ngenkathi uhamba emgwaqweni, kanye nokubona umuntu okude.
Bekungaba lula kangakanani uma izibuko ezinde zingakusiza kuyo yonke le misebenzi emithathu? Yilokho okwenziwa yi-Progressive Lenses.
Lawa abizwa nangokuthi ama-Progressive Addition Lenses (ama-PAL). Kungenzeka ukuthi uke wazibona izibuko ze-``Bifocal`` noma ``Trifocal`` ezazisetshenziswa omama bethu, obaba, kanye nogogo nomkhulu. Ilensi ibukeka njengomugqa ophansi maphakathi, akunjalo? Lowo mugqa uhlukanisa ibanga kanye nombono oseduze. Kodwa into ekhethekile ngama-Progressive Lenses ukuthi akukho mugqa onjalo obonakalayo ngaphandle . Ngenxa yokuthi ushintsho lwamandla lwenzeka kahle ngaphakathi kwelensi, umbukeli akakwazi ukubona ukuthi ilensi evamile noma enamandla amaningi.
Ubani ngempela odinga lezi zinto?
Impendulo eyinhloko yalo mbuzo ukuthi abantu abaningi abaneminyaka engaphezu kwengu-40 bangase badinge lezi.
Cabanga nje, awukwazi ukubona izinhlamvu ephephandabeni ngokucacile njengoba wawuvame ukubona? Wake wadinga ukubamba ifoni yakho kancane emehlweni akho ukuze ufunde umlayezo ? Lesi yisimo esivame kakhulu esenzeka ngokuhamba kwesikhathi. Ukuguquguquka kwelensi ngaphakathi kwamehlo ethu kuyancipha, okwenza kube nzima 'ukugxila' ezintweni eziseduze. Kwezokwelapha, lokhu sikubiza ngokuthi i -Presbyopia . Abantu abaningi bakubiza nangokuthi "i-presbyopia".
I-Presbyopia ayisona isifo. Iyingxenye yemvelo yenqubo yokuguga. Ngakho-ke asikho isizathu sokwesaba noma sokuba namahloni ngakho.
Ngakho-ke uma unenkinga yokubona kude (isibonelo, ukubona eduze - i-Myopia), futhi ngemva kweminyaka engu-40, lapho kuqala i-Presbyopia, kuzodingeka usebenzise izibuko ezimbili. Yilapho-ke ama-Progressive Lenses eba usizo kakhulu.
Futhi, odokotela ngezinye izikhathi bangase batuse lolu hlobo lwelensi ezinkingeni zokubona izingane ezingase zibhekane nazo.
Zikhona yini izinhlobo zamalensi aqhubekayo?
Yebo, kunezinhlobo eziningana zamalensi aqhubekayo ongakhetha kuzo kuye ngezidingo zakho nendlela yakho yokuphila. Ake sibheke izinhlobo eziyinhloko.
| Uhlobo lwelensi | Lokhu kufanelekela bani futhi yini ekhethekile ngakho? |
|---|---|
| Amalensi Aqhubekayo Ekhompyutha | Lezi zibizwa nangokuthi "amalensi okugxila aseduze." Lokhu kufaneleka kakhulu kumuntu osebenza phambi kwekhompyutha isikhathi esingaphezu kwamahora amane ngosuku. Ngoba indawo yokubuka yala malensi yenziwa ibe banzi ebangeni eliphakathi (isikrini sekhompyutha). |
| Amalensi Aqhubekayo Ephambili | Lezi yizinhlobo ezinhle kakhulu. Ziwuhlobo lwelensi eyenzelwe ngokukhethekile ukulingana nobuso bakho, kucatshangelwa amandla amehlo akho, ibanga eliphakathi kwamehlo akho, nokuthi yiliphi iso eliyiso lakho elilawulayo. Lezi zinikeza umbono ocacile kakhulu. |
| Amalensi Aqhubekayo Abuka Phansi | Lezi zilungele labo abenza imisebenzi edinga ukuthi babheke phansi, njengabagalufu nabaqwali bezintaba. Zenzelwe ukunikeza umbono ocacile lapho bebheka phansi. |

| Amalensi Aqhubekayo Okuguqukayo | Lezi zizinto ezinhle kakhulu. Uma ungaphakathi endlini, zikhanya njengezibuko ezivamile. Kodwa uma uphuma elangeni, uma ubhekene nemisebe ye-UV elangeni, la malensi aphenduka abe mnyama ngokuzenzakalelayo, njengezibuko zelanga. |
Yiziphi izinzuzo zamalensi aqhubekayo?
Empeleni kunezinzuzo eziningana kulolu hlobo lwesibuko.
- Konke ngesibuko esisodwa: Lena inzuzo enkulu kunazo zonke. Ubunzima bokushintsha phakathi kwezibuko ngokubuka ibanga, eduze, kanye nekhompyutha sebuphelile. Ungenza wonke umsebenzi wakho ngesibuko esisodwa .
- Ubunzima obuncane, kulula: Kulula kangakanani ukunakekela isibuko esisodwa kunokunakekela ezimbili noma ezintathu? Kufanele uthathe esisodwa kuphela uma uphuma futhi uhambahamba. Futhi mancane amathuba okukhohlwa.
- Ukubukeka: Lokhu kubalulekile kubantu abaningi. Njengoba kungekho migqa kulensi, akekho ozokwazi ukuthi ugqoke amalensi amaningi. Kubukeka njengezibuko ezivamile. Lokhu kuhle kakhulu kubantu abasha noma labo abangafuni ukukhombisa ukuthi bayaguga.
- Ukucindezeleka okuncane kwamehlo: Kulezo zibuko ezinemigqa ethi 'Bifocal', uma ubheka into ekude bese usondela, uzwa isithombe sigxuma. Akumnandi emehlweni. Njengoba amandla e-Progressive Lenses eshintsha kahle kakhulu, akukho ukugxuma okunjalo kwesithombe. Ngakho-ke, umbono ungokwemvelo kakhulu futhi amehlo awakhathali kakhulu.
Ingabe kukhona okuhle nokubi?
Njenganoma yini, kungaba nezinkinga ezimbalwa ezincane kulokhu, futhi kuhle ukuzazi nazo.
- Kubiza kancane: Amalensi aqhubekayo abiza kancane kunezibuko ezivamile ezi-bifocal. Kodwa cabanga ngakho ngale ndlela: kungase kube kushibhile ukuthenga izibuko ezi-1 kunokuthenga izibuko ezi-3 ezihlukene: eyodwa yokubona eduze, enye yokubona kude, kanye neyokusebenzisa ikhompyutha.
- Izinketho zohlaka olulinganiselwe: Ngenxa yokuthi amandla amathathu ala malensi adinga ukubekwa ezindaweni ezifanele, ilensi idinga ukuphakama okuthile. Ngakho-ke, la malensi angase angangeni ezinhlakeni ezincane kakhulu.
- Umbono We-Peripheral ufiphele kancane:Lokhu ukungakhululeki okuyinhloko abantu abaningi ababhekana nakho ekuqaleni. Uma ubheka phambili, umbono wakho ucacile kakhulu. Kodwa uma ubheka kusukela kolunye uhlangothi kuya kolunye ngaphandle kokujika ikhanda lakho, umbono wakho ungase ungabonakali kahle futhi izithombe zingase zibonakale zeluliwe emaphethelweni kwesokudla nakwesobunxele belensi. Kodwa ungakhathazeki, amehlo akho nobuchopho bakho kuzojwayela lokhu ngemva kwesikhashana.
Kuthatha isikhathi esingakanani ukujwayela lesi sibuko?
Lona umbuzo abantu abaningi abawubuzayo. Akukho mpendulo eyodwa kulokhu ngoba kuyahlukahluka kuye ngomuntu nomuntu.
Abanye abantu bangajwayela lezi zingilazi esikhathini esingangesonto noma amabili . Kwabanye, kungathatha inyanga noma ezimbili . Ezimweni ezingavamile, othile angase angakwazi ukuzijwayela nhlobo futhi uzobuyela ezingilazini zakhe ezindala.
Okumele ukwenze nje ukuzijwayeza ukubekezela. Udinga ukuzikhumbuza:
- Uma udinga ukubona kude , gcina ikhanda lakho liqondile bese ubheka phezulu kwelensi.
- Uma udinga ukubona kude, njengakukhompyutha , bheka engxenyeni ephakathi yelensi.
- Uma udinga ukubheka into eseduze, njengencwadi noma ifoni , phakamisa ikhanda lakho kancane, wehlise amehlo akho, bese ubheka phansi kwelensi.
Ungakhathazeki. Ezinsukwini ezimbalwa zokuqala, ungase uzizwe unesiyezi noma ungaphilile kahle. Lokhu kuvamile. Ngemva kwesikhathi esithile, ubuchopho bakho namehlo akho kuzojwayela le ndlela entsha yokubona.
Kufanele ngimbone nini udokotela?
Kungakhathaliseki ukuthi ungumuntu omdala noma ungumntwana, kubaluleke kakhulu ukuhlolwa kwamehlo akho okungenani kanye ngonyaka noma emibili . Amandla amehlo ethu angashintsha ngokuhamba kwesikhathi.
