Ngaba ufumanisa ukuba xa ufunda iphephandaba okanye ujonga ifowuni yakho, oonobumba abacacanga? Okanye awuboni izinto ezikude, njengophawu lwebhasi okanye oonobumba kwiTV, ngokucacileyo? Mhlawumbi xa uqhuba imoto ebusuku, ukukhanya okuvela kwizibane kubonakala ngathi kuyasasazeka? Uninzi lwethu luhlangabezana nezinto ezinje ebomini bethu. Isisombululo esilula nesiqhelekileyo koku kukusebenzisa iiglasi.
Ngamafutshane, iiglasi zeliso ziilensi ezimbini kwifreyimu ezisetyenziselwa ukukunceda ubone ngokucacileyo. Zilungisa iingxaki zokubona emehlweni akho. Zezinye zezixhobo zonyango ezisetyenziswa kakhulu kwihlabathi lanamhlanje.
Kutheni sifuna iiglasi? Iintlobo eziphambili zeengxaki zokubona
Iiglasi zamehlo ikakhulu zilungisa iimeko ezibizwa ngokuba ziimpazamo zokurhawuzelela. Oko kukuthi, ukungakwazi ukugxila kwimitha yokukhanya engena elisweni ngokufanelekileyo. Makhe sijonge ukuba zeziphi ezi ntlobo ziphambili zeempazamo.
| Igama lokukhubazeka kokubona | Kalula nje... |
|---|---|
| Ukubona kufutshane/i-Myopia | Izinto ezikufutshane nawe (incwadi, ifowuni) ungazibona ngokucacileyo, kodwa izinto ezikude (uphawu lwebhasi, iTV) azicacanga. |
| Ukubona kude/i-Hyperopia | Izinto ezikude zingabonakala ngokucacileyo, kodwa xa ujonga izinto ezikufutshane (njengokufunda iphephandaba), amehlo aziva ediniwe kwaye engacacanga. |
| I-Astigmatism | Oku kunokubangela ukuba umbono okufutshane nowakude ungabonakali. Olunye uphawu kukuvela kwemigca ejikeleze izibane, ingakumbi ebusuku. |
| I-Presbyopia | Le yimeko yendalo eyenzeka njengoko sikhula (ngesiqhelo emva kweminyaka engama-40). Amandla eliso okujonga izinto ezikufutshane ayancipha. Yingakho abantu abaninzi befuna iiglasi ezahlukeneyo ukuze bafunde amaphephandaba. |
Ungayiphucula njani indlela obona ngayo ngale miglasi?
Cinga ngeliso lethu njengekhamera. Ukukhanya okuvela ngaphandle kufuneka kudlule kwi-cornea kunye nelensi engaphambili kweliso kwaye kugxile ngqo kwi-retina engasemva kweliso. Kulapho kuphela apho sinokubona ngokucacileyo.
Okwenzekayo kumntu ongaboni kakuhle kukuba olu kukhanya alujoliswanga ngqo kwi-retina. Iilensi ezikwiiglasi zamehlo zigoba imisebe yokukhanya engena elisweni ukuya kwinqanaba elifunekayo kwaye zenze ukuba iwele ngqo kwi-retina. Ngokuchanekileyo, zinceda iliso ukuba lenze into elingenakukwazi ukuyenza lodwa.
Abanye abantu banokubona izinto ezimbini ngaxeshanye (ukubona kabini) ngenxa yomahluko omncinci kwindawo yamehlo abo. Le meko ingalungiswa ngokusebenzisa iilensi ezikhethekileyo.
Ziziphi iintlobo eziphambili zeeglasi?
Kukho iintlobo ezahlukeneyo zeelensi ezifanela ingxaki yakho yokubona. Ugqirha wakho uza kucebisa uhlobo olufunayo.
| Uhlobo lwelensi | Kuza kwenzeka ntoni koku? |
|---|---|
| Iilensi zombono omnye | Le lensi inamandla elinye kuphela. Nokuba kukubona umgama okanye ukubona kufutshane. |
| Iilensi ze-multifocal | Ezi ziqulathe amandla aliqela kwilensi enye. Ziyakwazi ukubona kufutshane nakude. |
| IiBifocals | Olu luhlobo lwe-multifocal. Ilensi inamandla amabini. Ihlala ifana nomgca ophakathi kwelensi. Ungabona kude ngenxalenye ephezulu kunye nenxalenye ekufutshane (umz. ukufunda) ngenxalenye esezantsi. |
| IiTrifocals | Kukho amandla amathathu apha. Ungabona kude, umgama ophakathi (umz., isikrini sekhompyutha), kunye nakufutshane. Nalapha, imigca eyahlula amandla iyabonakala. |
| Iilensi eziqhubekekayo | Oku kukwafana ne-bifocal, kodwa akukho migca injalo. Amandla ayatshintsha kancinci ukusuka phezulu ukuya ezantsi kwelensi. Ijongeka njengeglasi eqhelekileyo. |
| Iiglasi zokufunda | Ezi zenzelwe ukubona okukufutshane kuphela. Zinceda abantu abane-presbyopia ukuba bafunde amaphephandaba neencwadi. |

- Coca kakuhle: Sula nje ngelaphu le-microfiber elimanziswe ngamanzi amancinci anesepha okanye isitshizi esenzelwe le njongo.
- Musa ukwenza ezi zinto: Ungaze usule iiglasi zakho ngekona yehempe yakho, iphepha lethishu, okanye iphepha langasese. Iifayibha ezikuzo zinokukrwela ilensi kwaye zonakalise uqweqwe.
Ndifanele ndimbone nini ugqirha?
