Ngaba wakha wanamathela ekuzameni ukukhetha ilokhwe ethi, "Ingaba le luhlaza okwesibhakabhaka? Okanye mfusa?" Okanye wakha waziva ngathi ubona umbala owahlukileyo xa umhlobo wakho ekubonisa? Mhlawumbi wamangaliswa kukubona unyana wakho esebenzisa umbala omdaka endaweni yoluhlaza xa wayefaka umbala kumfanekiso. Izinto ezinje zixhaphake kakhulu phakathi kwethu. Isizathu soku singaba ngumahluko omncinci kwindlela amehlo akho abona ngayo imibala, ebizwa ngokuba yiColor Vision Deficiency. Namhlanje siza kuthetha ngovavanyo oluza kukuxelela ukuba yintoni kanye kanye le, eyaziwa ngokuba yi'Color Blind Test'.
Yintoni kanye kanye 'uVavanyo lokungaboni ngemibala'?
Ngamafutshane, olu luvavanyo apho ugqirha wakho, ingakumbi ugqirha wamehlo, ekuvavanya ukuze abone kakuhle ukuba ubona imibala kakuhle kangakanani. Nangona sibiza oku ngokuthi 'uvavanyo lokungaboni imibala', ligama elingafanelekanga. Kuba xa sisithi 'ukungaboni', sicinga ngokungaboni nto. Kodwa le meko ayikokulahlekelwa ngokupheleleyo kombono wombala. Ukungaboni imibala ngokupheleleyo yimeko engaqhelekanga kakhulu.
Okwenzekayo kukuba eminye imibala, ingakumbi ebomvu neluhlaza, okanye eluhlaza okwesibhakabhaka nomthubi, kunzima ukuhlulahlula. Ngoko ke igama elichanekileyo loku kukuvavanya ukubona imibala . Oku kukuvavanya indlela oyibona kwaye ubona ngayo imibala.
Ugqirha wakho angenza olu vavanyo xa usiya kuvavanyo lwamehlo oluqhelekileyo. Okanye umntwana wakho angenza olu vavanyo ngexesha lovavanyo lwamehlo esikolweni. Baza kukwazisa ukuba kukho utshintsho kwindlela umntwana wakho abona ngayo umbala kwaye ukuba kufuneka abone ugqirha wamehlo.
Ngaba Iimvavanyo Ezikwi-Intanethi Zinokuthenjwa?
Kule mihla, abantu abaninzi abarhanela ukuba banengxaki baya kwi-intanethi bayikhangele. Ukuba ukhangela 'uvavanyo olungenambala', uza kufumana uvavanyo oluninzi kwi-intanethi. Ukuba unokungabaza nokuba mncinci malunga nombono wakho wombala, ukuthatha uvavanyo olufana nolu kungaba yindawo elungileyo yokuqala.
Kodwa khumbula oku. Uvavanyo olukwi-intanethi luyindlela nje yokulinganisa uvavanyo lwezonyango lokwenyani. Alunakuze luqinisekise ngokuqinisekileyo ukuba unengxaki yokujonga imibala. Ngokuqinisekileyo kufuneka ubonane nogqirha, ingakumbi ugqirha wamehlo, kwaye ufumane uvavanyo olufanelekileyo.
Ziziphi iintlobo zovavanyo? Zenziwa njani?
Ngenxa yokuba kukho iintlobo ezahlukeneyo zokungabikho kombono ocacileyo, kukho iintlobo ezahlukeneyo zovavanyo ekufuneka zihlolwe. Kodwa zonke ezi vavanyo zilula kakhulu, zikhawuleza, kwayeAkukho ntlungu konke konke. Ugqirha uza kukubonisa imifanekiso aze akubuze ukuba ubona ntoni. Le isenokuba yimifanekiso ekwikhadi, ezincwadini, okanye kwiscreen sekhompyutha.
Kukho iintlobo ezininzi eziphambili zovavanyo.
1. Uvavanyo lwePlate yoMbala
Ezi zezona vavanyo zisetyenziswa kakhulu. Zikwabizwa ngokuba yi-"pseudoisochromatic plate tests." Kolu vavanyo, ucelwa ukuba uchonge inani, imilo, okanye unobumba onombala owahlukileyo ngokuchasene nemvelaphi yamachaphaza amancinci anemibala nobukhulu obahlukeneyo. Ungayibona kuphela imilo ukuba unokwahlula phakathi kwemibala emibini.
2. Uku-odola iiMvavanyo
Kwezi mvavanyo, unikwa iseti yamakhadi okanye iibhloko zemibala eyahlukeneyo uze ucelwe ukuba uzicwangcise ngokulandelelana okuthile ngokwemibala yazo. Umzekelo, ungacelwa ukuba uzicwangcise ngokulandelelana ukusuka kubhlowu obukhanyayo ukuya kubhlowu obumnyama.
3. Uvavanyo lokuthelekisa
Ezi zezona ndlela zichanekileyo zokuchonga ukungabikho kombala obomvu noluhlaza. Nangona kunjalo, azisetyenziswa rhoqo kwiikliniki. Zisetyenziswa kakhulu kuphando. Kusetyenziswa isixhobo esikhethekileyo esibizwa ngokuba yi-"Anomaloscope" kule nto.
Ngoku makhe sijonge ngokweenkcukacha ezinye zezona vavanyo zisetyenziswa kakhulu.
| Igama lovavanyo | Ujonga ntoni? | Indlela yokwenza oko |
|---|---|---|
| Uvavanyo lwe-Ishihara | Ukungabikho kombala obomvu-oluhlaza kubantu abadala. | Babonise amaphepha angama-8 ukuya kuma-34 anamachaphaza uze ubacele ukuba batsho inani okanye uphawu olufihliweyo apho. |
| Uvavanyo lwe-HRR lwaseRichmond | Zombini iingxaki zombala obomvu-oluhlaza kunye noluhlaza okwesibhakabhaka-otyheli kunye nobunzima bazo. | Amaphepha angama-24 asekelwe kumachaphaza anikezelwe ukunceda abafundi ukuba bachonge iimilo ezifana nezikwere, izangqa, kunye noonxantathu. |
| Uvavanyo lwe-CVTME (lwabantwana) | Ukungabikho kombala obomvu noluhlaza kubantwana abancinci abaneminyaka emi-3 ukuya kwemi-6 ubudala. | Endaweni yamanani, anikwa iimilo ezilula ezifana nezangqa, izikwere, neenkwenkwezi, kunye nemifanekiso efana neenqanawa nezindlu ukuze zichongwe. |
| Farnsworth-Munsell D-15 | Zombini iingxaki zombala obomvu-oluhlaza kunye noluhlaza okwesibhakabhaka-otyheli . | Iibhloko zemibala eli-15 ezahlukeneyo zinikwe ukuba zicwangciswe ngokulandelelana kwemibala yazo. |
Zithini iziphumo zovavanyo?
Eyona nto ilungileyo ngolu vavanyo kukuba akufuneki ulinde ixesha elide ukuze ufumane iziphumo. Ugqirha ufumana iziphumo kwangoko emva kokuba ugqibile. Emva koko uyakuchazela ngamagama alula:
- Luhlobo luni lokungabikho kokubona imibala olunalo (umz. obomvu-luhlaza okanye oluhlaza okwesibhakabhaka-mthubi).
- Bungakanani ubunzima bayo (oko kukuthi, ingaba ithambile, iphakathi, okanye inzima).
Ngamanye amaxesha, ukuba uvavanyo olunye alukwazi ukuxilonga ngokuchanekileyo imeko, ugqirha unokukuthumela kwenye i-test.
Cinga ngayo, nokuba ubunale meko ukususela ebuntwaneni, kusenokwenzeka ukuba ubungayazi. Abanye abantu bafumanisa ngengozi ukuba abakwazi ukubona imibala ethile kakuhle. Ngoko ke ukuba unamathandabuzo, thetha nogqirha wakho ngokunyanisekileyo ngayo. Mxelele kanye into oyibonayo, indlela oyibona ngayo.
Olu asilovavanyo "lokuphumelela" okanye "lokungaphumeleli". Akukho zimpendulo "ezichanekileyo" okanye "ezingalunganga". Luvavanyo nje lokuqokelela ulwazi malunga namehlo akho kunye nokubona kwakho.
Ukuba ndinengxaki yokujonga imibala, ndimele ndenze ntoni?
Ukuba ugqirha wakho ukuxelela ukuba unengxaki yokubona imibala, ungakhathazeki okanye woyike. Le yimeko eqhelekileyo echaphazela izigidi zabantu kwihlabathi liphela.
Le meko idla ngokubangelwa zizinto ezibangela ufuzo. Oko kukuthi, yinto edluliselwa kwizizukulwana ngezizukulwana. Ke ngoko, akukho "nyango" lwale meko okwangoku. Nangona kunjalo, zininzi iindlela zokukunceda uphile ubomi obuqhelekileyo, obungenazo iingxaki ngayo. Ugqirha wakho uza kukucebisa ngokwemeko yakho.
Ukunika imizekelo embalwa:
- Iiglasi okanye iilensi ezikhethekileyo:Kwezinye iintlobo zokungaboni imibala, kukho iintlobo ezikhethekileyo zeelensi ezinceda ukwahlula imibala.
- Itekhnoloji iyanceda: Ungasebenzisa ii-apps ezikwiifowuni ukukunceda ubone imibala ekunzima ukuba uyibone.
- Kubomi bemihla ngemihla: Izinto ezilula ezifana nokubhala iilebheli kwiimpahla nokukhumbula indlela ezibekwe ngayo phezulu, phakathi, nasezantsi kwizibane zendlela zinokwenza ubomi bube lula.
- Kubantwana: Ukuba umntwana wakho unale meko, kubaluleke kakhulu ukuxelela utitshala esikolweni ngayo. Emva koko utitshala angasebenzisa imibala elula ukuba umntwana ayiqonde xa efundisa izifundo.
Eyona nto ibalulekileyo kukwazi le meko kwaye ulungise ubomi bakho ngokufanelekileyo. Ugqirha wakho uza kukunika lonke ulwalathiso olufunekayo koku.
Umyalezo Wokuya Ekhaya
- Ukungaboni imibala asinto yokoyika njengoko unokucinga. Yimeko eqhelekileyo kubantu abaninzi kwihlabathi liphela.
- Nangona kuyinto entle ukwenza uvavanyo kwi-intanethi, musa ukuthembela kuphela kwiziphumo. Soloko ubona ugqirha wamehlo ukuze ufumane uxilongo olufanelekileyo.
- Uvavanyo lokujonga imibala luvavanyo olulula kakhulu, olukhawulezayo, nolungenabuhlungu.
- Olu asilovavanyo. Ngoko ke xelela ugqirha ngokunyaniseka nangokuchanekileyo oko ukubonayo ngexesha lovavanyo.
- Nokuba ufunyaniswe ukuba unesifo sokungaboni imibala, ungaphila ngempumelelo nangolonwabo naso. Kukho iindlela ezininzi kunye netekhnoloji ekhoyo namhlanje ukukunceda wenze njalo.
