Ukubuka konke

Uma uke washaywa ekhanda lakho futhi "wabona izinkanyezi," lezo zibani zazingekho emcabangweni wakho.

Imigqa noma ukukhanya kokukhanya kumbono wakho kuchazwa njengokukhanya. Kungenzeka uma ushaya ikhanda lakho noma ushaywa esweni. Zingavela futhi kumbono wakho ngoba i-retina yakho idonswa yi-gel esweni lakho leso.

• amahlule egazi emithanjeni yegazi e-retina, okuyimithambo yegazi ehambisa igazi kwi-retina yakho
• ukutheleleka ngegciwane esweni lakho
• izinkinga ezijwayelekile kusukela ekuhlinzweni kweso
• izifo ezizimele njenge-lupus
• izimila ezinamehlo

I-lobe yomsebenzi

Ingqondo yakho yakhiwe izingxenye ezine eziyinhloko, noma ama-lobes. I-lobe ye-occipital ingemuva kobuchopho bakho. Inesibopho sokuhumusha izimpawu zezinzwa ezisuka esweni lakho.

Uma ubheka isihlahla, i-retina yakho iguqula leso sithombe sesihlahla sibe amasignali ezinzwa asuka ku-retina adlule emsipheni we-optical siye ebuchosheni. I-lobe yakho ye-occipital icubungula lezo zimpawu ukuze ubuchopho bakho buqaphele leso sithombe njengomuthi.

Uma ushaywa ekhanda, izicubu ezise-lobe yakho ye-occipital ziyanyakaziswa. Amaseli obuchopho abe esethumela imizwa kagesi engahleliwe, ubuchopho bakho obukuhumusha njengokukhanya kokukhanya okungabonakala njengezinkanyezi.

I-anatomy yeso

Akuthathi njalo iqhubu ekhanda ukufaka izinkanyezi emkhakheni wakho wokubona. Ukuqonda ukuthi kungani, kuyasiza ukwazi okwengeziwe mayelana nokwakheka kweso lakho.

I-retina iyisendlalelo somzimba esincanyana esingemuva kweso lakho esizwela kalula. Ingxenye yeso lakho lemehlo ngqo phambi kwe-retina iqukethe i-vitreous, into efana ne-gel esiza iso lakho ukuthi ligcine isimo salo. Kukhona nemicu emincane, emincane kakhulu ku-vitreous. Lapho le micu idonsa ku-retina yakho noma i-gel ihlikihla i-retina yakho, ungabona izinkanyezi.

Uma i-retina yakho idonswa kanzima kakhulu noma isuka endaweni yayo ejwayelekile, umphumela ungaba yi-retina detachment. Lokhu kungadala ukuthi ubone izinkanyezi. Kungadala nokuthi ulahlekelwe yikho konke noma ingxenye yombono wakho kulelihlo. I-retina ethintekile ingahle iphathwe ngempumelelo ngokuhlinzwa.

Ikhanda le-Migraine

Enye imbangela yezinkanyezi kumbono wakho ukuphathwa yikhanda elibuhlungu. Akuwona wonke umuntu one-migraines obona izinkanyezi noma izibani ezimibalabala (ezaziwa nangokuthi i-aura), kepha abaningi bayazibona.
