Ukuwohloka kwezinto ezibukwayo kwakubhekwa njengenkinga ehlobene nobudala kuphela. Kodwa maduzane, izifo zamehlo ezihlukahlukene "zakhulile" futhi ziyatholakala ngisho nasezinganeni. Enye indlela yokugcina isimo siwubuyiselwe ukubuyisela lo mbono ngokwendlela kaZhdanov. Umlobi walolu lwazi ingumqondo wezengqondo nomchwepheshe we-physicist, owafunda ngokucophelela isakhiwo somzimba wamehlo, kanye nemisebenzi yabo.
Iyiphi indlela kaZhdanov yokubuyisela umbono esekelwe?
Le ndlela yokwelapha izifo zamehlo isekelwe emsebenzini we-ophthalmologist Bates owaziwayo. Ngokusho kwengqondo yakhe, noma yiziphi izinkinga zamehlo ziqala ngenxa yokusebenza kabi kwemisipha ebazungezile.
Iqiniso liwukuthi ukugxila nokuhlanza kwenziwa ngenxa yesisindo sezinsizi zeso. Ukucindezeleka ngokweqile noma ukukhululeka ngokweqile kwemizimba enjalo kubangela ukuwohloka okusheshayo kombono. Ngenxa yalesi sizathu, uBates njalo uncoma ukuthi awugqoki izibuko. Yiqiniso, kanye nabo, abantu babona kangcono kakhulu, kodwa izesekeli ezinjalo zivumela imisipha ye-eye ukuba ikhululeke ngokwengeziwe, ngokulandelana, futhi izinkinga nombono zizoqhubeka.
Ukuzivocavoca, okuhlinzekwa yi-ophthalmologist, kunikeza ukuqeqeshwa okujulile kwezixhobo zemisipha nokuqinisa kwayo. I-Zhdanov indlela kaBates eguquliwe kancane futhi iyasakazwa.
Kubalulekile ukuphawula ukuthi ubuchwepheshe obuchazwe akuyona i-panacea, kusiza kuphela izifo zamehlo ezithile:
- ukubuka okufushane ;
- i-astigmatism;
- ukubhekwa phambili.
Ezimweni ezingavamile, ingasetshenziswa ekulwa no- presbyopia .
Ngaphezu kwalokho, ukuvocavoca akuhlinzeki ngokubuyiselwa okuphelele kombono, ikakhulukazi ezimweni ezinganakiwe. Isikhulu esingabalelwa kuso sithuthukisa ukucaca kwe-diopters engu-1-2 kanye nokuvimbela i-concomitant pathologies.
Ukuzivocavoca ukubuyiswa kwemvelo kwemvelo usebenzisa indlela yeZhdanov
Isisekelo sazo zonke izici ezichazwe yi-palming. Kuyindlela elula yokuphumula ngokuphelele imisipha enamehlo futhi uwavumele aphumule.
Kulula ukwenza i-palming, udinga ukugubha izintende zakho ngokumelene nomunye, ukuvala iminwe yakho ukuyifudumala. Khona-ke kumelwe ukuthi ihlungwe ngakwesokudla, uhlangothi lwangaphakathi kuwe, iminwe yesandla esisodwa imboze enye. "Umklamo" oholela ekubekeni amehlo avaliwe ukuze abe phakathi kwezintende zezandla, impumulo ibheke phakathi kwezisekelo zeminwe encane, kanti iminwe yayitholwe ebunzini. Kubalulekile ukuthi ukukhanya akungena ngezandla.
I-Palming ithatha amaminithi angu-5-7. Kungenziwa ngaso sonke isikhathi lapho kunomzwelo wokubheka kakhulu amehlo, kukhona ukubhuka, izitsha ezishaya indiza. Emva kwalokhu, imisipha ikhululekile ngokuphelele, futhi imisebenzi yabo ijwayelekile.
Ngaphezu kwe-palmming, kubalulekile ukwenza izivivinyo ezikhethekile ngokusebenzisa indlela yeZhdanov yokubuyisela umbono:
- Ngokushesha futhi kaningi ukukhanya, ngokucindezela ngokucindezela amehlo akhe, iminithi elingu-1.
- Ngaphandle kokuchofoza, vula amehlo akho ububanzi (izikhathi ezingu-15-30) bese ubuyisa esimweni sabo sokuqala.
- Ukubuka okuhlukile, phansi, kwesokunxele nokulungile. Phinda izikhathi ezingu-15.
- Yenza umbuthano phambi kwamehlo bese uyibuka ngokuyikhipha, okokuqala ngqa, bese ulwisana nalo. Yenza izikhathi ezingu-10-12.
- Vala amehlo akho imizuzwana engu-3 uphinde uphumule.
- Vula amehlo akho bese uphinda izivivinyo.
Ngokuhamba kwesikhathi, ungaba nzima ukuvivinya umzimba, ungeze izakhi ezintsha kuwo. Isibonelo, ngemuva kweviki lezifundo, i-Zhdanov isincoma ukuthi ucacise nje umbuthano ongacabangi, kodwa futhi nezinye izibalo - umugqa, i-sinusoid ("inyoka", uphawu lokungapheli), kanye ne-diagonals.
Inkimbinkimbi egcwele yombono ukubuyiselwa indlela kaZhdanov
Umbhali wezinkambiso ezethuliwe ubheka ukuthi ukuzivocavoca nje kuphela okwanele. Ngakho-ke, wakha isakhiwo sakhe esiyinkimbinkimbi ekwelapheni izifo zamehlo, okungezelela kwalokho kuhlanganisa namasu okusebenza kwengqondo (isiteleka seShichko nokususwa kwezinhlelo ezingalungile kusuka ekuzileni) nokudla kwamalungiselelo akhethekile.
Isayensi ifakaze ukuthi izinto ezimbili zokugcina azisebenzi, kodwa ukuvocavoca kwamehlo kuyasebenza ngempela.
