Ukuphazanyiswa kwemisebenzi yombono kwenzeka ngezizathu ezihlukahlukene. Kungaba:
- izifo ze-ophthalmic;
- ukulungiswa kwefa;
- inkinga yamehlo ende, njll.
Enye yezinketho zokulungiswa kombono okungezona okwemvelo igqoke izibuko ezinezimbobo (izigqoko eziphazamisayo).
Izibuko ezinezimbobo zisebenza kanjani?
Izibuko emgodini wokuthuthukisa umbono yizingqwembe zepulasitiki ezinezimbobo ezincane ezincane, ezihlelwe ngokuhleleka okukhulu, ezakhiwe yi-plastic, izinsimbi ezincane kakhulu. Isimiso sesenzo sezingilazi ezimnyama nezimbobo sisekelwe emthonjeni wekhamera ye-pinhole noma i-stenstop. Ngenxa yobukhulu obuncane bokuvula, ukuhlakazeka kokukhanya ku-retina kuncishisiwe, futhi isithombe esiphelele siba sobukhali futhi sibukhali.
Ingabe izibuko ezinezimbobo zisiza ukubuyisela umbono?
Umbuzo wokusebenza kahle kwesenzo sezingilazi ze-glasses-simulators kuphakamisa izingxoxo ezinkulu. Abanye ochwepheshe-i-ophthalmologists bakholelwa ukuthi le divayisi ayinayo umphumela wokwelashwa, futhi ukuthenga izibuko eziphambene nakho kungukuchitha imali.
Eminye i-oculists ikholelwa ukuthi ukusetshenziswa okuhlelekile kwezibuko ezinezimbobo kusiza ngesikhathi esifanele ukuxazulula ukungezwani okuvela emisipha yomuntu ngamunye, futhi kunomthelela ekwakheni umthwalo othile emisipha ebuthakathaka. Ukuzivocavoca kweso eside futhi okujwayelekile ngosizo lwezibuko ezinjalo kuhloswe ukwandisa ubuciko obubukwayo yi-0.5-1.0 diopters. Akuvamile ukuthola imiphumela emihle ekubuyiseleni umbono.
Izinkomba zokusetshenziswa kwezibuko ze-perforation
Amalazi okulungiswa kombono emgodini anconywa ukuba asetshenziswe kulezi zimo ezilandelayo:
- ukubhekwa phambili;
- ukubuka okufushane;
- i-astigmatism;
- i-anisometropia (okuhlukile okubonakalayo emehlweni);
- i-presbyopia (ukushintsha kwe-lens);
- i-asthenopia (i-eye strain).
Akunqatshelwe ukusebenzisa izibuko eziphazamisayo lapho
Indlela yokusebenzisa izibuko ngezimbobo?
Ukufeza umphumela wokwelashwa okudingekayo, kuyadingeka ukusebenzisa ama-glass-simulators for cishe isigamu sehora ngosuku. Emisebenzini yobuchwepheshe ehilela umthwalo obalulekile obukwayo, kunconywa ukugqoka izibuko imizuzu engu-10 ngemuva kokusebenza kwamahora angu-1-1.5. Kubalulekile ukuthi ungagxila kwisifundo esisodwa ngesikhathi, kodwa ukubheka izinto eziseduze nezikude, okwenza amehlo akho ahambe njalo. Isikhathi sokwenza ukwelashwa okungenani ngonyaka owodwa.
