Sizuze umbono. Elisebenzayo bekhubazekile

Sizuze umbono - yintoni na le nto? Impendulo yalo mbuzo, uya kufunda evela manqaku thaca. Ukongeza, uya kufumana inkcazelo malunga nendlela, noko ingxaki eye abantu nazo amaxesha amaninzi, nendlela yokuzifumana.

ulwazi jikelele

Xa yezonyango, elikholisa ukubizwa ngokuba isiphako esiphoso of refraction. mgaqweni ezifana - iingxaki iliso ixhaphakileyo. Umongo weli qela kwezifo kukuba inkqubo woqondo ye iliso akakwazi kukugxininisa kwimitha ukukhanya retina, leyo nokushukunyiswa zethu ukukhanya Umbhalisi. Uphawu engundoqo kunye ngenxa yale meko zophendlo lwezifo na umbono olihlwempu.

Vision iphutha nesakhiwo sayo

Oku kuphambuka ingase ibe uphawu eyahlukileyo. iziphene ezininzi eziqhelekileyo namhlanje edulusele ngaphandle, ezizezi:

• astigmatism;
• ukubona okanye ukubona kuthiwa;
• ezikude okanye hyperopia;
• blindness umbala okanye imibala;
• Agnosia umbala.

Ukuze siqonde isizathu sokuba kukho umbono isiphako esithile kufuneka siqwalasele iimpawu izinxaxhi thaca iinkcukacha ezingaphezulu.

astigmatism

Isizathu sokuba uphuhliso imeko zophendlo lwezifo olunjalo ngokungachanekanga ezimilise umzimba optic inwebu. Kufuneka kuqatshelwe ukuba uphuhliso astigmatism kuchaphazela ngqo iliso lens ukubana xa kuthelekiswa esqwini of refraction. Zombini zikhankanywe izizathu kubandakanya umahluko kwimigama ukuba kubalulekile ukuba bajolise "imifanekiso".

Loo sizuze umbono unaliso linye esinokudibanisa iimpembelelo hyperopia, ukubona kunye nombono eqhelekileyo.

Ukubona, okanye ekuthiwa ukubona

Ukubona kunokwenzeka ngenxa yezizathu eziliqela. Eyokuqala ukwandiswa iliso, lo gama kugcinwe i index echanekileyo. Njengoko ku isizathu lesibini, refraction enombala enamandla kakhulu nto leyo diopters mkhulu kuno-60, lo gama ubude umzimba optic kuluhlu yesiqhelo. Zombini ezinxaxhileyo thaca kuchaphazela ngokungalunganga yokwamkela kumfanekiso yesiqhelo. Ngamanye amazwi, umfanekiso akanako ingqalelo retina, kwaye ibekwe ngaphakathi lweliso lakho. Ngenxa yoko, retina ufumana kuphela umfanekiso ejolise kuzo naziphi na izinto ukuba umgama omfutshane kude umntu.

Ukuze kulungiswe le sizuze mbono, izigulane badla amisele iindondo ezikhethekileyo ezinceda ukwakha umfanekiso yechaneke ngaphezulu. Kulo mzekelo, umntu kuqwalaselwa izinto umgama ungakhange ukhwaze. Ukuba isigulane myopic zibonwa ngokucacileyo, esebenzisa lenses thabatha okubangela izinto ezikude.

Ezikude, okanye hyperopia

Loo isiphako kuphuhlisa ngenxa refraction enombala buthathaka kakhulu kwi amalungu ezibonwayo lo gama kugcinwe ubude eqhelekileyo lweliso lakho. Kufuneka kuqatshelwe ukuba isizathu hyperopia kunye kunciphisa eba ukhozo lweliso ekulondolozweni amandla zokunganyangeki.

Ngenxa yokuba iliso hyperopic ayikho nako ukwenza eyona retina, izihlunu kwempixano kwandisa kakhulu. Le meko kuxhaphaka ukutshintsha ugobile lens, nto leyo ikhokelela kwingcamango welungu olubonakalayo phantsi kweemeko ezikhoyo. Nangona kunjalo, oku akwanelanga ukuba ugxininiso eqhelekileyo mfanekiso.

Xa ucinga izinto kufuphi ijwabu, izihlunu umzimba sentetha phezulu ngakumbi. Ngamanye amazwi, le nwebu into, kokukhona kubonakala phezu umfanekiso retina.

Zeziphi iindlela ukuphelisa zamehlo, hayi kanye mandithi, ukuzeka kade bisayo? Ukuze kulungiswe ukutenxa kwindlela enjalo iindondo ukusetyenziswa plus ne lenses. Bancedisa ekwakheni umfanekiso kakuhle ngokwaneleyo.

Njengoko usazi, xa kuzalwa usana, amehlo akhe zixinaniswe kancinci tye. Yiyo loo nto bonke abantwana abancinane ezithile ezikude. Nangona kunjalo, kwinkqubo yokuphuhliswa kombono abo zibuyela esiqhelweni.

Ukuba iqondo ezikude ebantwini lincinane, kude kufuphi umbono inokuba eqhelekileyo. Kodwa kwangaxeshanye abantu baya ezikhala yintloko kakhulu nokudinwa amehlo. Ukuba iqondo umyinge ezikude, kubonakala kufuphi umbono amahlwempu.

Umbala blindness, okanye imibala

Loo isiphako a yesifo awazalwa enaso, nto leyo eyenzeka ngokufuthi abantu. Umongo noku kutenxa kokumiselweyo kukuba izigulane baphazamiseke echanekileyo umbala imbono, iiseli zephotoreceptor adjustable (cone) kwiretina emehlweni. Ukuba ezinye iintlobo cone abantu akwanelanga, ngoko ke ngoku umbala ziimfama.

umbala Agnosia

Agnosia Umbala - uhlobo zokutenxa ezifana Agnosia olubonakalayo. Xa enjalo isigulane sifo nombono umbala yayinjalo ukuze ukwahlula imibala. Kukho kwakhona Agnosia Ngokuhambelana kunye neleta. Uxilongo lwala makhwiniba lufuna uviwo ngenyameko yi luvo. Ukumisela uhlobo Agnosia kunokwenzeka ngokusebenzisa iimvavanyo ezizodwa.

Unyango lwesi sifo na nothomalaliso esebenzayo zokutenxa, nto leyo eyakhokelela ekubeni ngokoyiswa amacandelo zobuchopho ngamnye. Amaxesha amaninzi Agnosia asinyangeki, nto leyo nobunzima kakhulu kumguli.

yeziphene imifuziselo le migraine lakudala

Migraine ne aura eqhelekileyo ixhaphake kakhulu into eyindoda. Kulo mzekelo, izigulane zinokuba ukuphazamiseka ezibonwayo. Bona ngesiqhelo ukukhanyisa iingongoma kubaneka molniepodobnyh, zigzags, iibhola, waza waba yintloko entle kakhulu. Ubunzulu la waphawula ukuba imizuzu embalwa okanye kwimizuzwana. Lidla le mifanekiso indawo abengezelayo ilahleko amanye amacandelo yasendle olubonakalayo. Kufuneka kuqatshelwe ukuba komgomo ezinjalo ngamanye amaxesha kudityaniswe antsi kobuso, isiqingatha umzimba kunye nolwimi, kunye ubuthathaka imilenze kuchasene intetho eqhelekileyo.
