Indlela Yokufanisa I-Presbyopia Okokuqala?

I-“Presbyopia” ibhekisela ebunzimeni bokusebenzisa amehlo eduze nobudala obuthile. Lesi yisenzakalo sokuguga komsebenzi womzimba womuntu. Lesi simo senzeka kubantu abaningi abaphakathi kweminyaka engama-40-45. Amehlo azozwa ukuthi umbhalo wesandla omncane ufiphele. Kufanele ubambe umakhalekhukhwini kanye nephephandaba kude ukuze ubone umbhalo wesandla ngokucacile. Kucace kakhudlwana ukubona izinto endabeni yokukhanya okwanele. Ibanga lokubuka iselula liba lide futhi libe lide ngokukhula.

   Uma kuvela i-presbyopia, kudingeka sigqoke izibuko zokufunda zamehlo ethu ukuze sikhulule ukukhathala okubukwayo. Kufanele sikhethe kanjani lapho sithenga izibuko zokufunda okokuqala?

1. 1.Umumo welensi kufanele ube banzi uma kuqhathaniswa. Ngenxa yomphumela ohlangene we-presbyopia lapho useduze kokubona nokufunda nokubhala, i-eksisi ebonakalayo yeso elilodwa kufanele ihanjiswe phansi futhi ibe ngu-2.5mm phakathi uma ilensi ikude (ikhanda libheke phezulu). Lapho bebuka amakhanda phezulu, abafundi ngokuvamile bangaphezulu nangaphansi komugqa omaphakathi weshidi lomumo, ngakho-ke ukuze izibuko zokufunda zibe nendawo eyanele yokubona, umumo weshidi kufanele uhlangabezane nemfuneko yokuthi ukuphakama okungaphezulu nokuphansi kufanele kube kukhulu kuno-30mm, hhayi ukuthi uma umumo weshidi ube mncane, ungcono. Uhlobo lwefilimu ewumngcingo phakathi kuka-25mm phezulu naphansi ngokuvamile luyaphatheka, futhi lusetshenziselwa ukwenezela kwesikhashana kokubona.

1. 2.Ingaphambili lezibuko kufanele libe banzi, kodwa i-OCD (ibanga elivundlile ukusuka esikhungweni se-optical) kufanele libe lincane. Njengoba abasebenzisi bezibuko zokufunda bonke baneminyaka ephakathi nangaphezulu, enobuso obugcwele amanzi, usayizi ovundlile wezibuko zokufunda ngokuvamile uba mkhulu ngo-10mm kunohlaka lokukhanya, kodwa ibanga eliseduze komfundi lincane ngo-5mm kunebanga lebanga le-pupillary, ngakho inani le-OCD labesifazane kufanele ngokuvamile libe ngu-58-61mm ngesikhathi esifanayo, Abesilisa kufanele bahlangabezane nezidingo ezimbili ngesikhathi esifanayo. kuyadingeka ukusebenzisa i-lens yobubanzi obukhulu futhi ube nesikhungo esikhulu sokunyakaza kwangaphakathi lapho wenza ilensi.
2. 3.Izibuko zokufunda kumele zibe namandla futhi ziqine. Izibuko ze-Presbyopic ziyizibuko eziseduze. Umthetho wokusetshenziswa kwamehlo ku-presbyopia wukuthi kusukela eminyakeni engu-40 (+1.00D, noma amadigri angu-100) ebangeni lokufunda, idinga ukwengezwa ngo-+0.50D (okungukuthi, ama-degree angu-50) njalo eminyakeni emi-5. Ngaphezu kwalokho, imvamisa yokukhumula nokugqoka ngesikhathi sokusetshenziswa izikhathi eziningi kunezingilazi ze-myopia, ngakho izingxenye zezibuko zokufunda kufanele zibe izinto eziqinile noma ezinwebeka kakhulu. Ukusebenza kwe-anti-corrosion kanye ne-anti-scratch kwe-electroplating kumele kuvelele, futhi inqubo yokuqina kwelensi kufanele ibe yinhle. Ngokuvamile, kufanele kuqinisekiswe ukuthi ngeke ikhubazeke kakhulu, igle, noma ikhuhlwe phakathi neminyaka emi-2 yokusetshenziswa. Eqinisweni, kulawa maphuzu, izidingo zezibuko ze-presbyopic ezinhle ziphakeme kunalezo zamafreyimu ezingilazi zebanga elifanayo.

Uhlobo luni lwezibuko ze-presbyopia ongakhetha kuzo olubaluleke kakhulu kubantu abagqoka izibuko okokuqala, ngoba umuntu ngamunye unokwehluka komuntu ngamunye, njengokuphakama okuhlukile, ubude bengalo, imikhuba yamehlo, kanye nezinga le-presbyopia emehlweni lihlukile. I-presbyopia yamehlo angakwesokunxele nangakwesokudla Idigri ingase ihluke, futhi abanye abantu banezinkinga zokubona ezifana ne-hyperopia, ukubona eduze, kanye ne-astigmatism ngesikhathi esifanayo ne-presbyopia. Uma ugqoka izibuko zokufunda ezingasifanele isimo sakho samehlo isikhathi eside, ngeke nje ixazulule inkinga, kodwa futhi kuzodala izinkinga ezinjengokuvuvukala kwamehlo nekhanda. Ngakho-ke, lapho inkinga ye-presbyopia yenzeka, kufanele siqale siye emnyangweni ojwayelekile we-ophthalmology noma isitolo se-optical for optometry, futhi ekugcineni sikhethe izibuko ezifanele ze-presbyopia ngokwesimo sethu.

Uma ufuna ukwazi okwengeziwe mayelana nezitayela zemfashini yezibuko kanye nokubonisana nezimboni, sicela uvakashele iwebhusayithi yethu futhi usithinte noma nini.
