Abathengi abaninzi bayabhideka xa bethenga iindondo zamehlo.Ngokuqhelekileyo bakhetha iifreyimu ngokwezinto abazithandayo, kwaye ngokubanzi baqwalasele ukuba iifreyimu zikhululekile kwaye ingaba ixabiso lifanelekile.Kodwa ukukhethwa kweelensi kuyadideka: yiyiphi i-brand efanelekileyo?Nguwuphi umsebenzi welensi ofanelekileyo kuwe?Zeziphi iilensi ezikumgangatho ophezulu?Xa ujongana neentlobo ngeentlobo zeelensi, ungayikhetha njani leyo ikufaneleyo?
Bakhetha njani abasebenzi baseofisini?
Abasebenzi baseofisini bahlala befuna ukujongana nekhompyuter ixesha elide, bade batshintshele emva naphambili phakathi kweemveliso ezahlukeneyo ze-elektroniki.Kulula ukubangela ukugqithisa kwamehlo, ukwandisa ukukhathala okubonakalayo.Ekuhambeni kwexesha, ukoma kwamehlo, ukunyanzeliswa kwamehlo, ukungaboni kakuhle kunye nezinye iimpawu ziye zavela, ezichaphazela ukusebenza kakuhle komsebenzi kwaye zixhomekeke kwiindidi ze "imiphumo emibi": intlungu yegxalaba nentamo, intloko, amehlo omile njalo njalo.
Ngoko ke, kubasebenzi baseofisi abasebenza ixesha elide kunye neemveliso ze-elektroniki, iilensi zabo kufuneka zibe nomsebenzi wokuchasana nokukhathala, ukuthintela ukukhanya okuluhlaza okulimazayo kunye nokukhusela impilo yamehlo.
Iimveliso ezifanelekileyo ziilensi zefotochromic ezinombala ogcweleyo, kunye neelensi ezichasene nohlaza okwesibhakabhaka.
Abafundi bakhetha njani?
Njengoko abafundi bephantsi koxinzelelo olukhulu lokufunda, indlela yokucothisa ngempumelelo kunye nokulawula ukukhula kwe-myopia ihlala iyinkxalabo enkulu kubafundi kunye nabazali babo.Izizathu ze-myopia kubantwana nakwishumi elivisayo zihlukile, ngoko ke ngaphambi kokuba ufumane incwadi kagqirha, kufuneka uqale ujonge uviwo lwe-optometric yobuchwephesha, kwaye emva koko ukhethe imveliso ehlangabezana neemfuno zakho ngokusekelwe kwiziphumo zovavanyo kunye nemeko yamehlo akho. , ukulibazisa ngokufanelekileyo ukuphuhliswa kwe-myopia.
Kubafundi abanoxinzelelo olukhulayo lokufunda, iimveliso ezifanelekileyo ziilensi eziqhubekayo, iilensi zokulwa nokudinwa, kunye nothintelo lwe-myopia kunye nokulawula iilensi ezinoyilo lweperipheral defocus.
Bakhetha njani abantu abadala?
Njengoko abantu bekhula, i-lens iguga ngokuthe ngcembe, kwaye ummiselo uyancipha, ukuze ngokuthe ngcembe bafumane umbono omfiliba kunye nobunzima bokubona kufutshane, into eqhelekileyo ye-physiological phenomenon, oko kukuthi, i-presbyopia.Ukuba baneziphoso zokuphinda babone xa bejonge kude, baya kuba nombono ongekho mfiliba kuyo yonke imigama.Ngoko ke, eyona mfuno yabo inkulu kukubona ngokucacileyo nangokukhululekileyo kuyo yonke imigama-ekude, ephakathi, ekufutshane- kunye nokwanelisa yonke inkqubo yomgangatho wokubonwa ophakamileyo.
Okwesibini, umngcipheko wezifo zamehlo ezahlukahlukeneyo (i-cataracts, i-glaucoma, njl.) iyanda ngokukhula, ngoko ke kufuneka iqondo elithile lokukhusela i-UV.
Ukuba ezi mfuno zingentla zidibene, abantu abaneminyaka ephakathi kunye nabakhulileyo banokukhetha iilensi ze-photochromic ze-presbyopia, ezifanelekileyo ngakumbi kubo.Okwangoku, ukuba babukele ezininzi zeTV kunye neeselfowuni, i-anti-blue light photochromic lens nazo zikhethwa kakuhle.
Ngelizwi, amaqela ahlukeneyo eminyaka ubudala, aneemfuno ezizodwa ezibonakalayo, afuna iindlela ezahlukeneyo zokuhlola impilo yamehlo ukucacisa iiparitha zeelensi zemithi kunye neemveliso ezahlukeneyo ukwanelisa abantu abahlukeneyo.
