Izibuko ze-Presbyopic zisetshenziswa abantu abaningi asebekhulile ukusiza ukubona.Kodwa-ke, abantu abaningi asebekhulile abacaci kahle mayelana nomqondo wokufunda izibuko, futhi abazi ukuthi kufanele bahambisane nezinhlobo ezinjani zezibuko zokufunda.
Ngakho-ke namuhla, sizokulethela isingeniso sendlela yokubala yokufunda izibuko.Masifunde ndawonye.
Iziqu zishintsha njalo.Ngokuvamile, inyuka ngo-50 degrees njalo eminyakeni emihlanu.Endabeni yamehlo amahle, ngokuvamile ama-degree angu-100 eneminyaka engu-45, ama-degree angu-200 eneminyaka engu-55, futhi ama-250 kuya ku-300 degrees eneminyaka engu-60. Esikhathini esizayo, izinga lezibuko ngeke lijule.Ngakho kufanele ibalwe kanjani idigri?
Imishini enguNo.2 esetshenzisiwe: isikali, amakhadibhodi, ukukhanya kwelanga
Izinyathelo zokusebenza:
1. Yenza izibuko zokufunda ziqonde esibukweni, bese ubeka ikhadibhodi ngakolunye uhlangothi.
2. Phinda ulungise ibanga phakathi kwe-paperboard nesibuko kuze kube ngu-tindawo encane ekhanyayo ivela ebhodini lephepha.
3. Kala ibanga f (ngamamitha) ukusuka endaweni ekhanyayo ukuya phakathi nendawo yesibuko ngesikali.Ingabe ubude bayo bokugxila.
4. Izinga lezibuko zokufunda lilingana nokuphindaphinda kobude bayo bokugxila obuphindwe ngo-100 ukuze kubalwe izinga lezibuko zokufunda.
Idigri engu-No.3 ye-presbyopia ihlobene neminyaka
Isibonelo, eminyakeni engu-45, imbali endala ingu-+1.50d (okungukuthi ama-degree angu-150).Lapho uneminyaka engu-50, kungakhathaliseki ukuthi ugqoka izibuko noma cha, imbali endala izokhula ibe +2.00d (okungukuthi ama-degree angu-200).
Kunezimbali ezindala.Uma ugcizelela ukuthi ungagqoki izibuko zokufunda, imisipha yakho ye-ciliary izobe ikhathele futhi ayikwazi ukuzivumelanisa.Ngokuqinisekile kuzokwandisa ubunzima bokufunda, kukhiqize isiyezi, ukuvuvukala kwamehlo nezinye izimpawu, futhi kuthinte impilo yakho nomsebenzi.Lokhu akuhlakaniphile neze.
Ngakho-ke, izibuko ze-presbyopia kufanele zifakwe ngokushesha ngaphandle kokulibala.Njengoba ukhula, izibuko zokufunda obuzigqoka azanele futhi kufanele zishintshwe ngesikhathi.
Uma asebekhulile befuna ukugqoka ama-lens aqhubekayo, kufanele bakhethe ngokucophelela.Uma unomuzwa wokuthi izibuko zokufunda azikufanelanga iziqu zakho, kufanele uzishintshe ngokushesha.Uma ugqoka izibuko ngezinga elingafanele isikhathi eside, ngeke nje kulethe ukuphazamiseka okuningi empilweni yasebekhulile, kodwa futhi kusheshise isivinini sokuguga kwamehlo asebekhulile.
Futhi uma uzithola une-presbyopia, ungafaki izibuko ze-presbyopia ngokushesha.Asebekhulile kufanele balisebenzise ngokunenzuzo ikhono labo lokushintsha amehlo abo futhi banikeze amehlo abo amathuba anele okuzivocavoca.
