Kutheni abafundi bexutywa: izibangela kunye nemiphumo

Umfundi ungumgodi ojikelezayo kwi- iris yeso, uhlobo lwesimbofu esingatshintsha ububanzi balo. I-photoreceptors enesisindo yeso lijongene nokuchaneka okungaqinisekiyo kwiinguqu kwiimitha ezikhanyayo. Ngokuxhomekeke kubukhulu bokukhanya, imisipha ekhethekileyo iyanciphisa okanye ikhulise ubungakanani bomgodi, ngaloo ndlela ilawula inani lokukhanya eliwela kwikhokhongo yangaphakathi - i-retina. Utshintsho kwiqondo lomfundi lenye yezona zibonakaliso ezibalulekileyo zomsebenzi kunye nombuso jikelele wengqondo. Akusiyo into yokuba kukho nawuphi na umboniso wefilimu ozinikezele kwiyeza eliphuthumayo, unokubona ukuba ugqirha ukhanyisa i-flashlight encinane kwiso lesigulane ukwenzela ukuba kubangele ukucutha komfundi kunye nokuvavanya izinga lokuqonda.

Utshintsho kubukhulu bomfundi lungabandakanywa kuphela ngezinga lokukhanya. Umzekelo, xa umntu ebona into ebangela umdla ophakamileyo, umfundi uyatshintsha ubukhulu bayo.

Ukuba abafundi baxutywa, izizathu zezi zinto zilandelayo zilandelayo: iimvakalelo ezinamandla, ukonwaba, ukunyuselwa kwenyameko, intlungu, ukwesaba. Kodwa kukho ukuphuculwa okusisigxina okusisigxina, ekugqibeleni kukukhokelela ekunqothulweni kweentsimbi ze- optic.

Umfundi kunye nezifo

Ukwandiswa okuqhubekayo kwabafundi begqirha kuthiwa i-mydriasis. Le meko ingabangelwa yimichiza okanye iikhemikhali ezinamandla (kubandakanywa neziyobisi).

Nangona kunjalo, oogqirha bathi ukuba ngaba abafundi bayanda, izizathu kufuneka zichongwe ngokukhawuleza. I-Mydriasis inokubangela ingcinezelo (zombini iso kunye nengqondo), kunye nesifo soxinzelelo, ukuhluthwa kunye nezinye izifo zengqondo. Nangona kunjalo, kwiminyaka eyahlukeneyo izizathu zokutshintsha okuqhubekayo ngobukhulu bezingane zihluke. Ukuba abafundi abadala baxutywa, izizathu zolu hlobo zingabhekiswa kwizilonda kunye nezifo zentambo ye-cerebral.

Kodwa ukuba kubonakala kwiintsana kunye nabantwana abancinci, akufanele uhlale uxhalabile. Ukuba ngaba abafundi bahlanjululwe kumntwana baqatshelwe, izizathu zolu hlobo zingabhekiswa kwimpawu zobomi zentsholongwane. Kuyaphawuleka ukuba abafundi beenyawo bahlukeneyo. Kwiimeko ezininzi, akufanele ukhathazeke. Kodwa ukuba umfundi ukhuliswe ngaphezu kwe-1 mm kwaye ngaphantsi kwefuthe lokukhanya ukuya kwisayizi yoqobo ayigodli, ke le sihlandlo sokudibana nodokotela.

U-Midriaz ebusheni uyisibonakaliso sengxaki

Njengoko kuchazwe ngentla, utshintsho kwindinganiso yomfundi kubangelwa iziyobisi ezifana ne-cocaine, i-LSD, i-marijuana, i-amphetamines nezinye izinto ezibulalayo. Ukuba abafundi abahlanjululwayo abaselula, izizathu zezi, njengombandela, azikhethekanga. Utshintsho oluqhubekayo ngobukhulu bomfundi kwinqanaba lokunyuka lithathwa njengophawu lomzimba lwezonyango. Nangona kunjalo, abazali kunye notitshala mabafanele bakhumbule ukuba into echasene nayo (ukunyanzelisa okuqhubekayo komfundi) nayo ibonisa uphawu lokuxhatshazwa kwezidakamizwa zeqela le-opiate. Umfundi unqabile ngokungaqhelekanga kwaye akayi kwandisa konke ebumnyameni obugqibeleleyo. Kodwa kwintsha yabafundi banokudityaniswa ngenxa yokugula. Musa ukulibala malunga ne-mydriasis ikuvumela ukuba ukhankanye isifo senkqubo yesifo okanye imithana yegazi. Ukongezelela, abafundi babukhulu obuhlukeneyo - lo luphawu lokuqala lwesifo seengqondo okanye intsholongwane enkulu.

Ukuba uqaphela ukuba wena okanye amalungu omndeni wakho ahlanjululwa, izizathu mazibekwe ngokukhawuleza. Abafundi abaninzi banika ubuhle emehlweni, kodwa banokubonisa ngentsingiselo nokugula.
