"I-myopia yengane yami ikhuphuka ngama-degree ayi-100 minyaka yonke. Sishintshe ama-pair amathathu ezibuko, futhi azikwazi ukubona kahle. Iyini ngempela inkinga?" Lokhu ukukhungatheka okuvamile okuzwakale kubazali emitholampilo yezifo zamehlo zezingane. I-optometry yendabuko ingasitshela kuphela ukuthi "ingakanani i-myopia," kodwa ayikwazi ukuphendula "ukuthi kungani kwenzeka" noma "ukuthi izoqhubeka kanjani."

Umbukiso We-24th China (Shanghai) International Optics Fair (SIOF 2026) ubanjwe ngomgubho kusukela mhla zi-2 kuya ku-4 kuNdasa 2026, eShanghai New International Expo Centre.

Amalensi anombala ogqamile kanye namalensi e-photochromic womabili ayizinketho ezidumile zezibuko zamehlo, ngalinye linikeza izinzuzo ezihlukile ngezinjongo nezilungiselelo ezahlukene. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zamalensi kusiza abathengi ukuthi benze izinqumo ezinolwazi ngokusekelwe ezidingweni zabo kanye nezintandokazi zabo.

Amalensi e-Photochromic, aziwa nangokuthi amalensi okushintsha, anikeza ikhambi elilula kubasebenzisi abadinga ukulungiswa kokubona kanye nokuvikelwa emisebeni ye-UV eyingozi yelanga. Lawa malensi ashintsha umbala ngokuzenzakalelayo ngenxa yokuvezwa yi-UV, avumela umbono ocacile ngaphakathi ngenkathi eba mnyama ngaphandle ukuze kuncishiswe ukukhanya futhi kuhlinzeke ngokuvikelwa kwe-UV.

Abathengi abaningi bazizwa bedidekile lapho bethenga izibuko zamehlo. Ngokuvamile bakhetha amafreyimu ngokusekelwe kulokho abakuthandayo, ngokuvamile becabangela induduzo kanye namanani afanele. Kodwa ukukhetha ilensi kuyadida: Yiluphi uhlobo lomkhiqizo olungcono kakhulu? Yimaphi amalensi afanelana nawe? Yimaphi amalensi anikeza ikhwalithi ephezulu? Uma ubhekene nezinhlobonhlobo zamalensi, ungakhetha kanjani elifanele wena?

Uma uya esitolo sezinto ezibonakalayo, abasebenzi bavame ukuncoma amalensi anezikhombisi eziphezulu, becaphuna izizathu ezinjengokuthi "Uma i-index iphezulu, i-lens iba ncane futhi ilula, futhi kuzoba lula ukuyigqoka."

Abantu abagqoka izibuko kungenzeka ukuthi bake baba nalezi zindaba: ukushiya izibuko zabo emotweni ehlobo, bese bethola imifantu emincane ivele emaphethelweni amalensi; noma ukugeza amalensi ngamanzi ashisayo bese beqaphela ukuthi ungqimba lokuvikela ukukhanya okuluhlaza okwesibhakabhaka ebusweni lubonakala lubuthakathaka.

1. I-Myopia ezinganeni
Uma i-myopia yangempela isitholakele, izibuko zamehlo zokulungisa kumele zinikezwe udokotela futhi zigqokwe. Ukuhlehlisa ukulungiswa kungabangela ukwanda kwaminyaka yonke kwama-degrees ayi-100 kuya kwangu-150.

Uma usesha ku-inthanethi ukuthi ayini amalensi okulwa nokukhathala, uhlangana nemibono lapho abantu bephikisana khona, njengokuthi "Ngokuyisisekelo bangabantu abathuthukayo abancane", "Bayinkohliso", "Bayasebenza ngempela", njalo njalo. Namuhla, sizoxoxa ngokuthi ayini amalensi okulwa nokukhathala nokuthi afanelekela obani.

Empilweni yansuku zonke, izibuko ze-photochromic zithandwa ngabathengi abaningi ngoba zingashintsha umbala wazo ngokushintsha kokukhanya, okunikeza lula ukusetshenziswa kwabantu ababili komunye nomunye. Ikakhulukazi, izibuko ze-photochromic ezibhalwe ngomuthi sezibe ukukhetha okusha kubantu abaningi.
