Ukuhlangabezana neliso: inkcazelo. Sazi njani bona? umsebenzi amehlo

nokwehliswa theory liso amazembe ezibonakalayo ngexesha nitrogen kwi into osenyongweni. Ngexesha le uncipha umfundi. Ukuhlanganiswa reflex eye yenzeka xa umbono binocular. ukuswela kwayo kudale strabismus ezahlukeneyo.

Indima iliso theory

Ukuhlangabezana iliso ludlala indima ebalulekileyo embonweni binocular, lo gama yokudibanisa imifanekiso ebonwayo monocular, ekudaleni iimeko eziyimfuneko ukuze naziphi zabo. Kubantwana, nto idla badlwengulwe.

Ukuphazamiseka Kuhlangana badla kukhokelela inkangeleko kunye nokwanda ukubona, uphuhliso ukubona yezihlunu. Lo mkhuba kakhulu kwaye abaxatyiswanga, ingakumbi abantwana kunye nabazali babo. Ukuze wenze oku, ukuze bangenele ukuhlangabezana iliso diagnostic. Indlela ukuhlola?

1. Abantu abadala kufuneka ukubeka usana nayo, uvale amehlo enye ngokwayo.
2. Ehlabathini phakathi umgama ukubeka ipensile nkqo ngendlela yokuba bambona yokuphatha isiqingatha umntwana iliso abadala evulekileyo ubuso, kwaye isiphelo eliphezulu ibekwe kwinqanaba amehlo.
3. Mkhuthaze umntwana wakho ukuba ukujonga omdala amehlo evulekileyo uze ubone ukuba zingaphi iipensile abone ngexesha elifanayo.
4. Ukuba umntwana ebona intonga "omnye", le nkqubo iphele. Uye uwaphule umbono binocular.
5. Ukuba i "ezimbini" ipensile, kufuneka ukuba ukujonga kuphela phezulu yento ngokucotha ukuba eze kobuso benkwenkwe leyo.
6. Ukuba akukho ukuhlangabezana, njengoko kukuhlangana ipensile nomntu umntwana iliso ngaphezu kwesinye ijonge empumlweni, okwesibini - ukuya etempileni.
7. Ukuba kukho ukuhlangabezana kwamehlo zosana ukuba symmetrically pivoted ukuya impumlo, lo gama i-umgama liye lancitshiswa-5 cm.
8. Emva koko cela umntwana wakho ukuba ukujonga ipensile imizuzu 1-1.5. Ukuba kukuhlangana iliso uzinzile, baya kufuneka ngokulinganayo waguqukela empumlweni.
9. Cebisa umntwana wakho ngaphandle ipensile ukujolisa amehlo zombini empumlweni. Ukuba kuvela ukuba "ukuhlangabezana nkani."

yokuhlukumeza Treatment theory

Ukuba akukho kukuhlangana iliso, kuyimfuneko ukwenza umthambo kwezonyango yonke imihla:

• Beka kumgama 30 ipenisile cm kunye ekhangele idlulileyo kuye. Oku kufuneka kubonwe imifanekiso njengoko ubuncinane ezimbini into.
• Kuqala kufuneka ujonge lo mfanekiso "ekunene" ye ipensile, ukuba abonakale yaye "ekhohlo", ngoko udlulisela jonga kwi "ekhohlo", ngaphandle kokulahlekelwa emehlweni enye.
• nitrogen enjalo ukuqhubeka ukwenza ngakumbi, kuqala ngokucothayo uze ngesantya uqhu-.

Ukuze kuphuculwe indlela yokusebenzisa ukuhlangabezana loqheliso izicelo ukwenza yonke imihla. Njengoko unako mzuzu emini.

Imithambo 1. Beka ipensile nkqo kwi-20 cm ukusuka iliso, malunga 20 imizuzwana ukukhangela kude, ukulungisa ingqalelo kumfanekiso kabini into, kukhangeleka kwi ipensile uze ujonge kuyo imizuzwana 5, ngoko kwakhona khangela kude uphinde intshukumo.

Imithambo 2. Misela ipensile ngokuthe nkqo kwi iingalo ubude, kancinane bangqale amehlo akhe phambi uqhoqhoqho, uze emva koko kancinane ukuyisusa ngokwayo.

Isifundo 3 isicelo convergence volitional. Yimani ejongene window ukuba kunina ebonakalayo. Force iza kunciphisa iliso impumlo, ephethe ekwisikhundla imizuzwana-7, ngoko kunciphisa umgama imbono kunye iliso kwakhona.

Ubume esweni kwabantu

Ngaphezu kwama-80% kolwazi abantu ngoko nendlela sibona. Ubume komzimba optic sinzima kakhulu. Kuxhomekeke imisebenzi iliso.

Apple iliso lomntu imilo sphere ezitenxileyo ezinokwenzeka. Le ibekwe ngaphakathi zisuke ukakayi. Ukususela ekuzalweni ukuya ekufeni, neziseko iliso kabini.

Enye indawo ebalulekileyo yile luvo optic. It edlulisela ulwazi neuron Occipital, uze emva koko zihlalutywe.

Ngenxa lacrimal ndlala phezu iliso uhlala ufumile. Iinyembezi lubricated kakuhle conjunctiva.

Indlela emayenziwe ngayo iliso ukhozo lweliso yabantu izihlunu gqolo ukwenza kunye. Le ezineziciko egubungele iliso, ngokukhuselwa izinto ezimbi. A umsebenzi ofanayo lwenziwa yi ngeenkophe.

Ubudlelwane lwesakhiwo kunye umsebenzi yamehlo

Ukuze siqonde isakhiwo welungu olubonakalayo kufuneka uthelekise lwecamera. Oku kudala umfanekiso ngokwenza ujoliso wakho esihlokweni nangokuvumela isixa esithile lokukhanya ucanda uvalo.

Xa umqadi engena iliso, udlula i inwebu, nto leyo kufikelelwe yi-75% ukukhanya ugxile. Emva koko ke uya umfundi, apho isixa-hlengiswe apha.

Lens - amehlo se yesibini. imilo balo buyahluka kunye ombane okanye nokuphumla kwezihlunu. Ukukhanya ejolise egqitha retina, nto leyo uguqulwe azilawule luvo. Emva kokuba afike umfanekiso ingqondo iisenta ithuba lokonwabela ihlabathi, ubukele imibala kunye izinto. Ngamanye amazwi, sonke sibona ebomini.

Isakhiwo ibonisa indlela esimbaxa iliso. Ochwepheshe Awukwazi ukufumana indlela lokususa izihlunu lweliso lakho, kuba luvo optic inovakalelo kakhulu.

umbono central

Got igama layo kuba inika ngundoqo retina kunye fossa central. Lo mbono ivumela umntu ukwahlula iimilo kunye neenkcukacha ezincinane izinto.

Nokuba yawa kancinane, umntu xa kube buqapheleke.

Uphawu ezingundoqo central umbono acuity na. ukufunda kubaluleke ekuvavanyeni izixhobo ezibonwayo abantu luphela, ukuba ukulandelela ezahlukeneyo iinkqubo zophendlo lwezifo.

acuity Visual - ukukwazi iliso ukubona iingongoma ezimbini, ezithi zibekwe kufutshane omnye komnye, kude elithile.

Kwakhona, kukho engile ingqiqo imbono emele angle oluthi luqokelelane phakathi iziphelo into uphononongwayo kwaye ndawo ifanelekileyo umzimba optic.

umbono neuropathy

Ngenxa kuye, abantu hlengisa ngokwabo kwISithuba ubone ebumnyameni.

Kuyimfuneko ukuba intloko ekunene nizithele amehlo nasiphi na isifundo, makube umfanekiso phezu kodonga, kwaye silungise inkangeleko ethile ye sezulu. Ukuba uyakwazi ukubona kakuhle, ithetha mbono engundoqo. Nangona kunjalo, ngaphandle kweli into entsimini lwembono owayo kunye nezinye izinto ezinkulu. Umzekelo, emnyango kwigumbi, ngubo, inja ehleli ecaleni komnye umgangatho. Ezi zinto ngokucacileyo ezibonakalayo, kodwa emehlweni, yaye kusenokwenzeka ukuba zifake isindululo. Lo mbono zomzimba.

amehlo abantu, kungekhona ukuhamba, unako kukugubungela 180 degrees ze kolundi kunye abanganeno kancinci (malunga ¹³⁰⁾ kwi ithe cwaka nkqo.

Le kabukhali kombono engundlunkulu ngakumbi xa kuthelekiswa neuropathy. Oku kungenxa yokuba inani cone ukusuka embindini ukuya kwezona engabalulekanga retina incinane kakhulu.

Yintoni kubhekwa umbono oluqhelekileyo

umbono oqhelekileyo abantu kungenxa refraction le umqadi kukhanya iliso, kungekhona kushenxwe kulo mmiselo. Ngenxa yoko, ilens, i inwebu, ilens nokudlulisela umfanekiso umfanekiso kwi retina kwi macula.

Umntu ngamnye umbono yakhe eqhelekileyo. Ixhomekeka ukuba uhlobo lwendawo isigulane ubona phezu kwetafile Golovin-Sivtseva. Eyaziwa unit kuthetha ukuba afunde kumgca-10. Kuyinto umbono eqhelekileyo.

ukuhlukunyezwa refraction

Refraction kuthiwa refraction ukukhanya emehlweni.

Ukuba Iplanga refracted ngokuchanekileyo, umfanekiso swi ngqo kwi retina. Imeko malungana (imposiso zokunganyangeki) kuphakamisa uphuhliso kunye ukuvela hyperopia kunye ukubona. Ukuba nawuphi na umfanekiso elivelayo ifiphale, bamphefumlo umbaxa. Kuba ukulungiswa isicelo iindondo zonyango kunye lens ezibangela umqadi ukukhanya ukuba baqwalasele kwiretina.
