Inkcazo: "Ukubona okwesibini" kubhekisela kutshintsho lwexeshana kwimbono ngexesha lokuphuhliswa kwe- cataract yokuqala. Ngaphambi kokuba umbono ubonakalise, umbono, ngokukodwa umboniso wokufunda, uphumelele kakhulu. Ezinye izigulane zibika ngokucacileyo kufuphi nombono ngaphandle kokusetyenziswa kweziglasi zokufunda . Umbono osondeleyo ubhekisela kumbono wezinto 2 iinyawo okanye kufuphi nombukeli. Ezi nguqu zenzeka ngenxa yokuba iiprotheni kunye nezinye izixhobo ezenza i- lens ziqala ukutshintsha isakhiwo.
Oku, utshintshe indlela yokukhanya evulela ngayo i-lens, eyenza ukuphuculwa kwexeshana kwimbono esondeleyo.
Ngaba wonk 'ubani uya kuvela "Usibini lwesibini?"
Nangona sonke siva utshintsho olwenzeka ngaphakathi kwilensi yethu, iziphumo zalo kuxhomekeke kukuphi uhlobo lombono wengxaki isigulane esasikhona ngaphambili, ukuba yintoni isimo sokukhusela esasiyiliso labo ngaphambili. Ngokomzekelo, ukuba sele sele ukhangelele, "Usibini lweSibini" luya kukwenza ube lula ngakumbi. Abantu abafumana iinjongo ze-"Second Sight" ngokubhekiselele kwizinto eziqhelekileyo okanye abanakho ingxaki yokubona ukuqala.
Kutheni i-crystalline lens ishintsha?
Amehlo ethu ahlala ephantsi kwengcinezelo evela kwezinye izinto. Enye inkqubo yokuba imizimba yethu ihlala isilwa ngumonakalo we-oxidative, ekubhekiselwe kuzo njengengcinezelo yenkomo. Uxinzelelo oluxhamlayo luyimfazwe eqhubekayo ukuba imizimba yethu ilwe nama-radicals amahhala, ayenama-molecule ane-oksijini asebenzayo kwaye awonakalisa iiseli emzimbeni wethu.
Uxinzelelo lwe-oxidative lungatshintsha iiseli ngaphakathi kwileniso liso elenza ukuba lens ilahlekelwe ngokucacileyo. Nangona le nkqubo ihamba ngokukhawuleza kuyo yonke into ebomini bethu, iyasifumana xa sikhula kwaye ngaphambi kokuchaphazela umbono wethu ngokubalulekayo, sisoloko sinokubona "okwesibini."
Yintoni i-cataract?
I-cataract i-clouding ye- lens eye. I-Cataract iyona nto ibangela ukuphosa phakathi kwabantu abadala kunama-55. Abaninzi abantu asebekhulile banomlinganiselo othile we-lens clouding, eyinto eqhelekileyo yokuguga. I-cataract ngokuvamile ayibuhlungu. Ngokuqhelekileyo iqala njengendawo encinci, i-opaque kwaye ikhula ngokukhawuleza. Imbono ayisoloko ichaphazeleka kude kubekho indawo enkulu yeli lens iba yinto ephazamisayo.Iimpawu ezibonakalayo ze-cataract zibonwa ngumbono, ukuqonda ukukhanya, ii-halos zijikeleze izibane, ukukhwabanisa ukuhamba ebusuku, ukusabalalisa umbono, ukufuna ukukhanya okungakumbi ukufundwa, umbono ombini okanye utshintsho olukhulu imiyalelo yeminwe.
Yintoni ongayenza xa ucinga ukuba unesibini?
Ukuba ucinga ukuba ufunda kakuhle kungekudala nje ngaphandle kweziglasi zakho, khangela i-optometrist okanye i-ophthalmologist.

I- refraction iya kubonisa ukuba isigunyaziso sakho sineengxaki ezinkulu.
Ugqirha lakho kwamehlo liza kuphucula amehlo akho kwaye lijonge phantsi kwe-bio-microscope ekhethekileyo ukuze ubone ukuba uphuhliso lwama-cataract luyenzeka okanye ufumana utshintsho oluqhelekileyo lwemithi.
