Rabkin ithebula polychromatic ukuba umbala Umbono test

imibala

Ukuze imibala banesibopho photosensitive yokwamukela amaseli retina - Izigaxa. Zintathu izinhlobo of Izigaxa, le Spectral ukuzwela ngobukhulu okuyizinto zenzeka izingxenye blue, oluhlaza futhi abomvu bohlu. Ngenxa izinhlobo abafanele of Izigaxa kuya eyinhloko imibala abantu abathathu bona izinkulungwane imibala kanye shades. Nge excitation ngesikhathi esisodwa 3 izinhlobo receptor, kukhona lokujabulela emhlophe.

ukwephulwa ka imibala

Uma ukwephula noma buthakathaka bezibona eminye imibala emithathu eyinhloko, umuntu uyayeka ukuba ngiziqonde yimuphi umbala. Umbono kahle obomvu okuthiwa Protanopes, oluhlaza - deuteranopia, blue - acyanopsia. Ukuphulwa imibala kungaba azalwa naso noma bathenga. amaphutha ezingavamile esizalwa nawo wokuhle bezibona blue and umusi igumbi, noma achromatopsia. Abantu abaningi abakwazi ukuhlukanisa abomvu kusuka oluhlaza, njengoba azibonayo lezi imibala like grey. Lokhu sifo ngokuthi umbala ubumpumputhe umbala umbono. Kuyinto isifo esidluliselwa ngofuzo landile kwabesilisa. Ukuze kuhlonzwe izifo usebenzisa polychromatic umbala ukuzwa opticians Rabkin etafuleni.

Yiziphi polychromatic ithebula Rabkin

Lamathebuli aqukethe umbala amachashazi ezahlukene ahlelwe ngendlela ethile ukuthi ezinye zazo ichazwe ngu lamatshwayo izinombolo noma imidwebo yejeyomethri. Endabeni ka ukwephulwa of ukubonakala kombala isiguli ubona izibalo ezifihliwe ayibonakali abavamile. Lamathebuli acabangele izinhlobo owamukelwa iziyaluyalu imibala, okuvumela ukuba nithole zokugula azalwa naso noma bathenga. Ucwaningo kungaba kwenziwe abadala kanye nezingane iminyaka engu-2 ubudala.

Izindlela ukutadisha kombala

• · Isihloko ehlezi ukuze umthombo wokukhanya kuyinto ngemuva komhlane wakho.
• · Amathebula ahlelwe thwi nehlo, at ibanga 1 imitha ukusuka kokuthathwayo.
• Ukuze ukubuyekeza kwethebula eyodwa akuzona ngemizuzwana engaphezu kwengu-10.
• · Uma ukuhlolwa ogqoka izibuko, khona-ke kumelwe kudlule izibuko test.
• · Ukuze ubone ukuthi iziyaluyalu azalwa naso test bacelwa ukuba sicabangele itafula ngamehlo amabili ngesikhathi esisodwa, futhi ukuba bakwazi ukubona izifo atholwe cwaningo eyenziwa iso yanjalo sokunene nesobunxele.
• · Izingane Umenyiwe ubiyela uphawu ibhulashi ukuthi babona etafuleni.

Ukuhlolwa imiphumela yocwaningo

1. umbono ovamile umbala (trihromaziya) - uma sasho 27 amathebula yochungechunge main.
2. umbala umbono okungavamile - uma ngokungalungile okuthiwa 1 - 12 amatafula.
3. Ukwephula okufanayo kombala (dihromaziya) - ngokungalungile okuthiwa amatafula 12 noma ngaphezulu.

ukufunda ongakhetha ithebula:

• lesifanele
• engaqinisekile
• okungafanele ejwayelekile
• okungalungile atypical
• ukufunda

Kukhona 3 amatafula bakwazi ukufunda kuphela labo zokugula kuluthola.
