Ayisebenzi yeumbono omnye:
Xa abantu abangaphezu kweminyaka engama-40 ubudala, iperi enyeiiglasi zombono omnyebasenokungakwazi ukuhlangabezana neemfuno zabo.Babekwazi ukubona umgama kodwa bengasondeli, okanye babone kufutshane kodwa kungekhona umgama.Ngeli xesha, kufuneka banxibe iiperi ezimbini zeeglasi, iiglasi zokufunda xa zisetyenziselwa ukubona izinto ezikufutshane kunye neendondo zomgama ukubona umgama.Enye indlela kukunxiba iiglasi ezininzi ezigxininise, kunye neeglasi ezigxininisiweyo ezininzi zibandakanyaiiglasi ze-bifocal kunye nenkqubela phambili.Iiglasi ezininzi ezigxininise kwiperi enye yeglasi zinokusetyenziselwa ukubona umgama kunye nokuvala, ungasebenzisa indawo ebona kude engaphezulu ukubona umgama kunye nendawo esezantsi ukubona izinto ezikufutshane.
Yintoni umahluko phakathiiqhubela phambili kunye ne-bifocal
1. Ii-Bifocals zikunceda ukuba ujonge kude nakufutshane kuphela, kwaye ziya kuvelisa imitsi yemifanekiso xa ujonge kufutshane emva kokuba ubone umgama.
2. Uya kufumana umbono oqhubekayo kuluhlu olukude, oluphakathi, kunye kufuphi nefocal ene-lens eqhubekayo, kwaye ngaphandle kwemigca, akukho mfanekiso uphazamisayo.
3. I-lens eqhubekayo iya kuba nexabiso eliphezulu kune-bifocals.Kodwa ixabiso elongezelelweyo lifanelekile ixabiso layo.
Ngubani ofunaiindondo eziqhubekayo
1. Njengoko iliso lomntu lisiya lisonakala ngenxa yokwaluphala, ngokuthe ngcembe ilensi iyaqina, nto leyo ebangela ukuba iliso lijonge ukukhanya ngasemva kunokuba lijonge kwiretina xa lijonge izinto ezikufutshane.Le yipresbyopia.Le nto ixhaphake phakathi kwabantu abaphakathi kunye nabantu abadala abangaphezu kweminyaka engama-40.
2. Ukuba une-myopia (ukubona kufutshane) okanye i-hyperopia (ukubona kude), udinga kuphelaiilensi zombono omnye, kodwa ukuba une-presbyopia kunye nenye yeengxaki ezimbini zombono ngaxeshanye, udinga iilensi eziphucula indlela ozibona ngayo izinto ezikufuphi nezikude.
3. Ezinye iintlobo zemisebenziiilensi eziqhubekayoziyafumaneka kwimisebenzi ethile.Xelela ugqirha wamehlo akho ukuba ufuna iiglasi ezikhethekileyo ngenxa yomsebenzi.Ngokufana nokuba uqhuba imoto kwindlela enesantya esiphezulu, kufuneka ujonge umgama, kwaye ubone ukuba ingakanani ioli eseleyo.
4. Ngoko ke, ukuba ufuna iipeni ezimbini zeeglasi zokufunda nokusebenzisa umgama, iindondo eziqhubekayo zinokukulingana.
Ilebhu yethu ixhotyiswe ngoomatshini abavela eSatisloh kwaye ifakwe i-OPTOTECH kunye ne-IOT yoyilo lwesoftware yeelensi eziqhubekayo zamahhala.Uyilo olwahlukileyo lufanelekile kwiinjongo ezahlukeneyo.
