Njengoko ubudala bukhula, ngokuqhelekileyo malunga nobudala be-40, umbono uya kuhla ngokuthe ngcembe kwaye i-presbyopia iya kuvela emehlweni.
I-Presbyopia, ngokwezonyango eyaziwa ngokuba yi "presbyopia", yinto yokuguga yendalo eyenzeka ngokukhula, okwenza kube nzima ukubona izinto ezisondeleyo ngokucacileyo.
Xa i-presbyopia ifika emnyango wethu, singazikhetha njani iiglasi zokufunda ezisifanelayo? Namhlanje, funda lonke inqaku
Indlela yokwahlula phakathi kwe "presbyopia" kunye ne "hyperopia"
Abahlobo abaninzi bacinga ukuba i-presbyopia kunye nokubona kude yinto enye, kodwa akunjalo. Ke mandiqale ndahlule phakathi kwe "presbyopia" kunye ne "hyperopia".
I-Presbyopia: Njengoko iminyaka ikhula, ukuqina kwe-lens yeso kuncipha kwaye amandla okulungelelaniswa kwe-ciliary muscle ayancipha. Ugxininiso lokukhanya olusuka kwiindawo ezikufutshane alunakuwela ngokuchanekileyo kwi-retina, okukhokelela ekuboneni okungacacanga kuluhlu olusondeleyo. Ngokwenyani, i-presbyopia ithetha "i-presbyopia" njengoko igama libonisa. I-Presbyopia ibonakala kuphela kubantu abangaphezu kweminyaka engama-40 ubudala.
I-Hyperopia: ibhekisela xa uhlengahlengiso lweliso lukhululekile, ukukhanya okungapheliyo okuhambelanayo kugxininise emva kwe-retina emva kokudlula kwinkqubo ye-refractive yeso (ukuba igxininise phambi kwe-retina, yi-myopia). Yi-hyperopia enokuthi ibe khona kungakhathaliseki ubudala.
Ndingazi njani ukuba ndine-presbyopia?
➢Ukungaboni kakuhle kuluhlu olusondeleyo: Olona phawu luqhelekileyo lwe-presbyopia kukubona luzizi kuluhlu olusondeleyo. Unokufumanisa ukuba xa ufunda incwadi, usebenzisa ifowuni yakho, okanye usenza omnye umsebenzi osondeleyo, kufuneka uyitsale incwadi okanye into ethile kude namehlo akho ukuze ubone ngokucacileyo.
➢Ubunzima bokufunda: Abantu abane-presbyopia banokukufumanisa kunzima ukufunda okanye ukwenza izinto kwiindawo ezinokukhanya okuphantsi. Kufuneka ukukhanya okungakumbi.
➢Kulula ukudinwa okubonakalayo: I-Presbyopia ihlala ihamba kunye nokuziva ukukhathala kwamehlo, ngakumbi emva kokusebenza kuluhlu olusondeleyo ixesha elide. Unokufumana amehlo omileyo, adiniweyo okanye ahlabayo.
➢Intloko kunye nesiyezi: Emva kokusebenza nzima ukulungisa ugxininiso ixesha elide, abanye abantu banokufumana iimpawu zentloko ebuhlungu okanye ukungakhululeki kwe-fundus.
Ukuba le meko ingentla iyenzeka, kufuneka siye kwivenkile yamehlo yobuchwephesha kwi-Optometry kunye neeglasi kwangexesha. Nangona i-presbyopia ingenakuguqulwa kwaye ayinakunyangwa, ukunxiba iiglasi ngokukhawuleza nangokuchanekileyo kunokunceda ukulibazisa ukuphuhliswa kwe-presbyopia.
Indlela yokufumana iperi efanelekileyo yeeglasi zokufunda?
1. Yenza uviwo lweOptometry kuqala
Ngaphambi kokunxibaiiglasi zokufunda, kuya kufuneka uqale uye kwivenkile yobugcisa ukuze ufumane irefraction echanekileyo. Abanye abantu abadala banokuba namanqanaba ahlukeneyo e-presbyopia emehlweni abo amabini, okanye banokubona kude, i-myopia, okanye i-astigmatism. Ukuba bathenga iperi esele yenziwe ngaphandle kwe-optometry yesayensi, kunokwenzeka ukuba kubangele uthotho lwezifo zamehlo kunye nokulahleka kombono. Ingxaki, singasathethi ke ukuba iintsana zamehlo omntu ngamnye zahlukile, ngoko ke kufuneka udlule kwi-Optometry yobungcali phambi kokuba unxibe iindondo.
Amandla okufunda iiglasi ahlala e-D, njenge +1.00D, +2.50D, njl. Kubaluleke kakhulu ukumisela umyalelo wakho nge-Optometry. Umyalelo ophakamileyo okanye ophantsi kakhulu uya kubangela ukuphazamiseka kunye nokudinwa okubonakalayo xa ufunda.
2. Iilensi zokufunda ezahlukeneyo zinokuxhotyiswa ngokweemfuno zamehlo ezahlukeneyo.
➢Ukuba uyi-presbyopic, hayi i-myopic, kwaye awuwenzi umsebenzi osondele kakhulu ngamaxesha aqhelekileyo, kwaye uyisebenzise kuphela xa ujonge iiselfowuni, iitafile, iikhompyuter okanye ukufunda amaphephandaba, ke iiglasi zokufunda zombono omnye zilungile, zinentuthuzelo ephezulu kunye nexesha elifutshane lokuziqhelanisa.
➢Ukuba amehlo akho omabini e-myopic kunye ne-presbyopic, ungakhetha iilensi eziqhubela phambili ezininzi: iperi yeelensi zomboniso ezinendawo ekugxilwe kuzo ezininzi, ezinokuhlangabezana neemfuno zamehlo akude, aphakathi nakufutshane. Iilensi ezininzi eziqhubekayo Isibuko esinye singasetyenziselwa iinjongo ezininzi. Akukho mfuneko yokuba uyivule kwaye uyivale, nto leyo eyenza kube lula ukuyisebenzisa.
Ukuba ufuna ukwazi ngakumbi malunga nefashoni yeglasi kunye nothethwano lweshishini, nceda undwendwele iwebhusayithi yethu kwaye uqhagamshelane nathi nangaliphi na ixesha.
