Ukuvavanywa kokusebenza kwemisipha engaphezulu

Umsebenzi wokuvavanywa kwemisipha owongezelelweyo uvavanya ukusebenza kwezihlunu zamehlo. Umboneleli wezempilo ujonga ukuhamba kwamehlo kumacala amathandathu athile.

Uyacelwa ukuba uhlale okanye ume ngentloko ujonge phambili. Umboneleli wakho uya kubamba usiba okanye enye into malunga nee-intshi ezili-16 okanye iisentimitha ezingama-40 phambi kobuso bakho. Umboneleli uya kuthi emva koko ahambise into kwiindlela ezininzi kwaye akucele ukuba uyilandele ngamehlo, ngaphandle kokuhambisa intloko.

Uvavanyo olubizwa ngokuba luvavanyo / lutyhile uvavanyo lunokwenziwa. Uya kujonga into ekude kwaye umntu owenza uvavanyo uya kugubungela iliso lethoni, emva kwemizuzwana embalwa, uyityhile. Uya kucelwa ukuba uqhubeke ujonge kude. Indlela iso elihamba ngayo emva kokuvezwa kwayo kunokubonisa iingxaki. Emva koko uvavanyo lwenziwa ngelinye iliso.

Uvavanyo olufanayo olubizwa ngokuba lolunye uvavanyo lwe-inshorensi lunokwenziwa. Uya kujonga kwinto ekude efanayo kwaye umntu owenza uvavanyo uya kugubungela iliso elinye, kwaye emva kwemizuzwana embalwa, shenxisela isiciko kwelinye iliso. Ke emva kweminye imizuzwana embalwa, buyisela kwakhona kwiliso lokuqala, njalo-njalo kwimijikelo emi-3 ukuya kwezi-4. Uya kuhlala ujonga kwinto enye nokuba yeyiphi iliso eligutyungelweyo.

Akukho lungiselelo lukhethekileyo luyimfuneko kolu vavanyo.

Uvavanyo lubandakanya ukuhamba okuqhelekileyo kwamehlo.

Olu vavanyo lwenziwa ukuvavanya ubuthathaka okanye ezinye iingxaki kwiimisipha ezingaphaya. Ezi ngxaki zinokubangela umbono ophindwe kabini okanye ukuhamba ngokukhawuleza, okungalawulekiyo kwamehlo.

Ukuhamba okuqhelekileyo kwamehlo kuwo onke amacala.

Ukuphazamiseka kwentshukumo yamehlo kunokuba ngenxa yokungaqheleki kwezihlunu ngokwazo. Zingakho ngenxa yeengxaki kumacandelo engqondo alawula ezi zihlunu. Umboneleli wakho uyakuthetha nawe malunga nokungaqhelekanga okunokufumaneka.

Akukho bungozi buhambelana nolu vavanyo.

Unokuba nenani elincinci lokungalawulwa kwamehlo okungalawulwayo (nystagmus) xa ujonge kwindawo esekhohlo okanye esekunene. Oku kuqhelekile.
