Kweli hlabathi apho ukucaca kunye nokufiphala kudibene, iiglasi ziye zaba ngumncedi onamandla kubantu abaninzi ukuba babone ubuhle ngokucacileyo. Namhlanje, masingene kwihlabathi elimangalisayo leeglasi kwaye sithathe ukhenketho lwesayensi yeglasi enomdla!
01｜ Isishwankathelo sophuhliso lweeglasi
Imbali yeeglasi inokulandelwa emva kwe-1268 AD. Iindondo zoqobo yayiziilensi nje ezilula ezisetyenziselwa ukunceda abantu abadala bafunde. Njengoko ixesha lihamba, iteknoloji iyaqhubeka iqhubela phambili, kwaye iintlobo kunye nemisebenzi yeeglasi ziba zininzi kwaye zininzi. Ukusuka kwiiglasi ze-myopia, iiglasi ze-hyperopia ukuya kwiiglasi ze-astigmatism, ukusuka kwiiglasi ezikhanyayo ukuya kwi-multifocal glasses eziqhubekayo, ukuphuhliswa kweeglasi kubonelele uluntu olungagungqiyo lokufuna umbono ocacileyo.
02｜Iintlobo zeeglasi
1. Iiglasi zeMyopia
Kubahlobo be-myopic, iiglasi ze-myopia ziyimfuneko. Isebenzisa umgaqo weelensi eziconcave ukwenza umfanekiso wezinto ezikude kwiretina, ukuze sikwazi ukubona izinto ezikude ngokucacileyo.
Ngokomzekelo, abafundi bajonga ebhodini eklasini kunye nabasebenzi baseofisini bajonge isikrini sokubonisa kude, zonke ezifuna uncedo lweeglasi ze-myopia.
2. Iiglasi ze-Hyperopia
Ngokwahlukileyo kwiiglasi ze-myopia, iiglasi ze-hyperopia zisebenzisa iilensi ze-convex ukunceda izigulane ezine-hyperopic zibone izinto ezikufutshane ngokucacileyo.
Ngokomzekelo, xa abalupheleyo befunda iincwadi baze balungise iimpahla, iindondo ezibona kude zidlala indima ebalulekileyo.
3. Iiglasi zeAstigmatism
Ukuba kukho ingxaki ye-astigmatism emehlweni, iiglasi ze-astigmatism ziya kuba luncedo. Iyakwazi ukulungisa imilo engaqhelekanga yeso kwaye igxininise ukukhanya ngokuchanekileyo kwiretina.
4. Iindondo zelanga
Ayisiyiyo kuphela into yefashoni, kodwa kunye nesixhobo sokukhusela amehlo kumonakalo we-ultraviolet.
Xa uhamba kunye nemisebenzi yangaphandle ehlotyeni, ukugqoka izibuko zelanga kunokunciphisa ngokufanelekileyo umonakalo wemisebe ye-ultraviolet emehlweni.
3｜Uzikhetha njani iindondo
1. I-Optometry echanekileyo
Eli lelona nyathelo lokuqala libaluleke kakhulu. Yiya kwivenkile yamehlo okanye esibhedlele ukuze ufumane i-Optometry ukuze ufumane idatha yombono echanekileyo.
Ngexesha leeholide zasehlotyeni, i-Clairvoyance Optical Shop ibonelela ngeenkonzo zasimahla zamehlo kuye wonke umntu.
2. Qwalasela izinto zesakhelo
Kukho iinketho ezininzi ezifana nentsimbi, iplastiki, kunye nepleyiti, ekufuneka igqitywe ngokwenduduzo, ubuhle kunye nomgangatho wolusu lomntu.
3. Imilo yesakhelo
Khetha ngokwemilo yobuso, umzekelo, ubuso obujikelezileyo bufanelekile kwisakhelo sesikwere, kunye nobuso besikwere bufanelekile kwisakhelo esijikelezileyo.
04｜Ugcino kunye nokugcinwa kweendondo
1. Ukucoca rhoqo
Sebenzisa ilaphu leeglasi ezikhethekileyo ukosula ngobunono kwaye uphephe ukusebenzisa izinto ezirhabaxa ukosula iilensi.
2. Ukugcinwa ngokufanelekileyo
Kuphephe ukudibana phakathi kweelensi kunye nezinto eziqinileyo ukuthintela imikrwelo.
Ngamafutshane, iiglasi azikho nje isixhobo sokulungisa umbono, kodwa kunye neqabane elihle ebomini bethu. Ndiyathemba ukuba ngesayensi yanamhlanje edumileyo, wonke umntu unokuba nokuqonda okunzulu kweeglasi.
Masisebenzise umbono ocacileyo wokuxabisa eli hlabathi lihle nelinemibalabala kunye!
Ukuba ufuna ukwazi ngakumbi malunga nefashoni yeglasi kunye nothethwano lweshishini, nceda undwendwele iwebhusayithi yethu kwaye uqhagamshelane nathi nangaliphi na ixesha.
