Njengoba iminyaka ikhula, ngokuvamile phakathi neminyaka engama-40, umbono uzokwehla kancane kancane futhi i-presbyopia izovela emehlweni.
I-Presbyopia, ngokwezokwelapha eyaziwa ngokuthi "i-presbyopia", isenzakalo esingokwemvelo sokuguga esenzeka ngokukhula, okwenza kube nzima ukubona izinto eziseduze ngokucacile.
Uma i-presbyopia ifika emnyango wethu, kufanele sikhethe kanjani izibuko zokufunda ezisifanelayo? Namuhla, funda sonke isihloko
Ungahlukanisa kanjani i-presbyopia ne-hyperopia
Abangane abaningi bacabanga ukuthi i-presbyopia kanye nokubona kude kuyinto efanayo, kodwa akunjalo. Ngakho-ke ake ngiqale ngehlukanise phakathi kwe-“presbyopia” ne-“hyperopia”.
I-Presbyopia: Njengoba iminyaka ikhula, ukunwebeka kwe-lens yeso kuncipha futhi amandla okulungisa emisipha ye-ciliary aba buthaka. Ukugxila kokukhanya okuvela ezindaweni eziseduze akukwazi ukuwela ngendlela efanele ku-retina, okuholela ekuboneni okungacacile ebangeni eliseduze. Uma sikhuluma ngokwezwi nezwi, i-presbyopia isho ukuthi “presbyopia” njengoba igama lisho. I-Presbyopia ngokuvamile ivela kubantu abangaphezu kweminyaka engama-40 ubudala.
I-Hyperopia: ibhekisela lapho ukulungiswa kweso kukhululekile, ukukhanya okuhambisanayo okungapheli kugxile ngemuva kwe-retina ngemva kokudlula ohlelweni lwe-refractive lweso (uma lugxile phambi kwe-retina, i-myopia). I-hyperopia engase ibe khona kungakhathaliseki ubudala.
Ngingabona kanjani ukuthi ngine-presbyopia?
➢Ukubona okufiphele ebangeni eliseduze: Ukubonakaliswa okujwayelekile kakhulu kwe-presbyopia ukubona okufiphele ebangeni eliseduze. Ungathola ukuthi lapho ufunda incwadi, usebenzisa ifoni yakho, noma wenza omunye umsebenzi oseduze, udinga ukudonsa incwadi noma into kude namehlo akho ukuze ubone kahle.
➢Ubunzima bokufunda: Abantu abane-presbyopia bangase bakuthole kunzima ukufunda noma ukwenza izinto ezindaweni ezinokukhanya okuphansi. Udinga ukukhanya okwengeziwe.
➢Ukukhathala okulula okubonakalayo: I-Presbyopia ivame ukuhambisana nomuzwa wokukhathala kwamehlo, ikakhulukazi ngemva kokusebenza ebangeni eliseduze isikhathi eside. Ungase ube namehlo omile, akhathele noma ahlabayo.
➢Ikhanda elibuhlungu nesiyezi: Ngemva kokusebenza kanzima ukulungisa ukugxila isikhathi eside, abanye abantu bangase babe nezimpawu zekhanda elibuhlungu noma ukungaphatheki kahle kwe-fundus.
Uma kwenzeka lesi simo esingenhla, kufanele siye esitolo sokubuka esichwepheshe ukuze uthole i-Optometry nezibuko kusenesikhathi. Nakuba i-presbyopia ingenakuhlehliswa futhi ingelapheki, ukugqoka izibuko ngokushesha nangendlela efanele kungasiza ukubambezela ukukhula kwe-presbyopia.
Ungalithola kanjani izibuko zokufunda ezifanele?
1. Yenza ukuhlolwa kwe-Optometry kuqala
Ngaphambi kokugqokaukufunda izibuko, kufanele uqale uye esitolo sezinto ezibonakalayo ukuze uthole ukuphinda okunembile. Abanye abantu asebekhulile bangase babe namazinga ahlukene e-presbyopia emehlweni abo amabili, noma bangakwazi ukubona kude, i-myopia, noma i-astigmatism. Uma bethenga ipheya esenziwe ngomumo ngaphandle kwe-optometry yesayensi, kungenzeka kubangele uchungechunge lwezifo zamehlo nokulahlekelwa umbono. Inkinga, ingasaphathwa eyokuthi amehlo omuntu ngamunye ahlukile, ngakho-ke kufanele uhlole i-optometry yochwepheshe ngaphambi kokugqoka izibuko.
Amandla ezibuko zokufunda ngokuvamile aku-D, njengokuthi +1.00D, +2.50D, njll. Kubaluleke kakhulu ukunquma incwadi yakho kadokotela usebenzisa i-Optometry. Imithi kadokotela ephakeme kakhulu noma ephansi kakhulu izobangela ukungakhululeki nokukhathala okubukwayo lapho ufunda.
2. Amalensi okufunda ahlukene angahlonyiswa ngokwezidingo zamehlo ezahlukene.
➢Uma une-presbyopic, hhayi i-myopic, futhi ungawenzi umsebenzi omningi osondelene ngezikhathi ezijwayelekile, futhi uwasebenzisa kuphela lapho ubuka omakhalekhukhwini, amathebulethi, amakhompyutha noma ufunda amaphephandaba, khona-ke izibuko zokufunda zombono owodwa ezivamile zilungile, ezinokunethezeka okuphezulu kanye nesikhathi esifushane sokuzijwayeza.
➢Uma amehlo akho ekuwo womabili ama-myopic kanye ne-presbyopic, ungakhetha amalensi aqhubekayo e-multifocal: amalensi embukwane anamaphuzu amaningi okugxilwe kuwo, angahlangabezana nezidingo zamehlo akude, aphakathi nendawo naseduze. Amalensi aqhubekayo e-multifocal Isibuko esisodwa singasetshenziselwa izinjongo eziningi. Asikho isidingo sokuyivula nokuvala, okwenza kube lula ukuyisebenzisa.
Uma ufuna ukwazi okwengeziwe mayelana nezitayela zemfashini yezibuko kanye nokubonisana nezimboni, sicela uvakashele iwebhusayithi yethu futhi usithinte noma nini.
