Icyerekezo cyawe ni ikihe? Reka tubiganireho mu buryo bworoshye!

Twese tubona kandi tugasobanukirwa iyi si nziza n'amaso yacu, si byo se? Tekereza gato, kuva tubyutse mu gitondo kugeza tugiye kuryama nijoro, tubona ibintu bingahe? Ubwo bushobozi bwo kubona no gusobanukirwa ibintu bwitwa kureba . Si ikintu cyoroshye gusa, ni igikorwa gitangaje cyane. None rero uyu munsi, reka tuganire ku kureba icyo ari cyo, uko bibaho, n'uburyo bwo kwita ku maso yacu.

Iyerekwa ni iki mu by'ukuri?

Mu magambo make, kureba ni uburyo amaso yawe n'ubwonko bikorana kugira ngo bikoreshe urumuri rugaragara mu bintu bikukikije kugira ngo bigufashe kubona ibintu. Ni kimwe mu byumviro bitanu by'ingenzi dufite. Abantu benshi basobanukirwa kandi bakamenya isi binyuze muri ubwo buryo bwo kubona.

Iki kintu cyitwa icyerekezo kibaho gite? Biratangaje!

Kureba bitangira iyo amaso yawe abonye urumuri, akaruhindura ibimenyetso by'imitsi, hanyuma akabyohereza mu bwonko bwawe binyuze mu mitsi yawe y'amaso . Ubwonko bufata ibyo bimenyetso, bukabisobanura, hanyuma bukabihindura amashusho ubona. Bisa n'ibigoye, sibyo? Reka tubicemo gato.

Amaso yawe: Ese ameze nk'amakamera abiri mato?

Ushobora kuba warumvise abantu bakunze kugereranya amaso na kamera. Ariko mu by'ukuri ni ibinyuranye. Kamera ni ikoranabuhanga ryakozwe nk'iry'ijisho ry'umuntu.

Tekereza kamera ifite lens ishyira urumuri ku kintu cyihariye kiri muri kamera. Iyo sensor ihindura urumuri mo ibimenyetso by'amashanyarazi. Mudasobwa nto iri muri kamera hanyuma ihindura ibyo bimenyetso mo ishusho. Ushobora kugenzura aho kamera ireba. Muri kamera zimwe na zimwe, ushobora no kugenzura ingano y'urumuri rukubita kuri sensor.

Amaso yawe afite kandi lens. Izi lens zishyira urumuri ku ruhu zikaruyobora kuri retina, iri inyuma y'ijisho. Retina isa n'icyuma gipima muri kamera, ariko iragoye cyane kandi iteye imbere. Umucyo ugwa kuri retina uhinduka ibimenyetso by'imitsi hanyuma woherezwa mu bwonko. Ibi bibaho inshuro nyinshi mu isegonda!

Ubushobozi bwihariye bw'izo kamera, ni ukuvuga kwibanda no kugenzura urumuri, bukorwa n'amaso yawe mu buryo bwikora . Imboni iri mu jisho ryawe ishobora kwaguka no kugabanuka, ibyo bikaba bigenzura ingano y'urumuri rwinjira mu jisho ryawe. Byongeye kandi, hari imitsi igenzura indorerwamo y'ijisho ryawe. Iyi mitsi ni yo ituma imirasire y'urumuri yibanda ku buryo ushobora kubona ibintu mu ntera zitandukanye neza.

Retina: Ahantu heza cyane ho gufata urumuri!

Retina yawe ni ubwoko bw'uturemangingo twihariye cyane kandi tworoheje cyane. Izo selile zitwa photoreceptors., ni ukuvuga "uturemangingo tumenya urumuri." Iyo urumuri ruguye kuri utwo turemangingo, habaho ingaruka za shimi n'amashanyarazi muri utwo turemangingo. Uko ni ko utwo turemangingo tumenya urumuri tukaruhindura ibimenyetso by'imitsi.

Hari ubwoko bubiri bw'ingenzi bw'utu turemangingo tw’urumuri (photoreceptors):

• Inkingi: Izi zishinzwe cyane cyane kumenya impinduka mu bushyuhe bw'urumuri. Inkingi nizo zigufasha kubona ibintu mu rumuri ruto, ni ukuvuga ahantu hijimye.
• Amasafuriya: Izi fotoreceptors zigira ubushobozi bwo kumva no kubona utuntu duto n'amabara atandukanye.

Iyo ibyo bimenyetso by’imitsi bihinduwe amashusho, retina yohereza ibyo bimenyetso ku mitsi yawe y’amaso.

Imitsi y'amaso: Insinga zijyana ubutumwa mu bwonko!

Imitsi yawe y'amaso imeze nk'insinga zitwara amakuru. Ihuza retina yawe n'ibice bitandukanye by'ubwonko bwawe. Ibyo bimenyetso bigenda mu mitsi y'amaso bikagera mu bice bitandukanye by'ubwonko bwawe, aho bisobanuka kandi bigatunganywa.

Ubwonko: Aho ifoto ikorewe!

Intambwe ya nyuma kandi y'ingenzi cyane iba mu bwonko bwawe. Ubwonko bufata ibimenyetso byanditseho amakuru biza mu mitsi y'amaso bukabisesengura. Hanyuma bukoresha ayo makuru yanditseho amakuru kugira ngo bukore "ishusho" ya buri jisho.

Bitewe n'ibyo ubona, ibice bitandukanye by'ubwonko bikorana kugira ngo bisobanukirwe neza iyo shusho. Urugero, iyo usomye iyi nteruro, ibice by'ubwonko bigufasha gusobanukirwa ururimi no kwibuka nabyo birakora. Uko ni ko ushobora gusobanukirwa aya magambo, ukibuka icyo asobanura, ndetse no kwibuka ibintu bifitanye isano nayo. Tekereza, niba ubona inshuti yawe mu muhanda, amaso yawe amaze gufata ishusho ye akayishyira mu bwonko bwawe, ubwonko bwawe burabimenya bugavuga buti "Oh, uyu ni Amal, sibyo?" kandi bigahura n'ibyo wibuka byose bifitanye isano (ibyo wavuganye na we, ibyo wasekanye na byo).

Ni izihe ndwara zishobora kugira ingaruka ku bushobozi bwacu bwo kureba?

Kugira ngo umuntu arebe neza bisaba ibice bitandukanye by'umubiri n'imiterere yawo kugira ngo bifatanye. Bityo, imiterere itandukanye ishobora kugira ingaruka kuri buri gice. Hari imiterere ishobora kugira ingaruka ku bice birenze kimwe.

Dore ingero zimwe na zimwe z'indwara zishobora kugira ingaruka ku bushobozi bwo kureba:

• Indwara ziterwa n'amaso: Urugero, indwara ya katarakte, glaucoma.
• Indwara zifitanye isano na retina n'imitsi y'amaso: Urugero, retinopathy ya diyabete na optic neuritis.
• Indwara ziterwa n'ubwonko: Urugero, kutabona neza bitewe no gucika intege mu bwonko, kutabona neza bitewe n'ibibyimba byo mu bwonko.

Ntugatinye ibi, ni ngombwa kubimenya. Niba ubonye impinduka, ni byiza gushaka inama kwa muganga.

Ese "Kureba" na "Kureba" ni ibintu bitandukanye?

Abantu benshi, ndetse n'inzobere n'abahanga mu bya siyansi, bakoresha amagambo "kureba" na "kureba" mu buryo bumwe. Ariko si ikintu kimwe. Tekereza ko ushobora gukoresha ubushobozi bwawe bwo kureba utabonye ikintu runaka (urugero, gukora amashusho mu mutwe wawe). Nanone, hari imimerere y'ubwonko aho ubwonko bwawe budashobora gutunganya ibyo amaso yawe abona.

Kugira ngo tubisobanureho gato:

Tekereza kubona nk'ubushobozi bufatika gusa . Ni ukuvuga ko amaso yawe abona urumuri, akaruhinduramo ibimenyetso by'amashanyarazi n'ibinyabutabire, hanyuma akarwohereza mu bwonko bwawe.

Kureba bisaba ubushobozi bwo gutunganya ibimenyetso biva mu maso yawe. Iyo udakoresheje ubwo buryo, ibimenyetso amaso yawe yohereza mu bwonko bwawe ntacyo bimaze.

Nubwo bishobora gusa n'ibitangaje gutekereza kuri ibi byombi ukwabyo, hari indwara z'ubwonko zigira ingaruka ku kureba ariko ntizigire ingaruka ku kureba. Urugero ni indwara yitwa imbonankubone . Umuntu ufite imbonankubone ashobora kubona, bivuze ko kureba kwe ari byiza, ariko ubwonko bwe ntibushobora gusobanukirwa cyangwa kumenya icyo abona. Urugero, iyo abonye igitoki, ashobora kutamenya ko ari igitoki. Indi ndwara yihariye ni Prosopagnosia . Abantu bafite iyi ndwara bashobora kubona amasura y'abantu, ariko ntibashobora kumenya abo ari bo. Bashobora kutamenya amasura y'umuryango wabo cyangwa inshuti zabo. Ese si igitangaza?

Ni gute narinda kandi ngakomeza kubona neza?

Hari ibintu byinshi ushobora gukora kugira ngo urinde kandi ukomeze kubona neza. Dore bimwe muri byo:

• Suzuma amaso yawe buri gihe: Buri wese agomba gusuzumwa amaso ye buri gihe , ndetse n'abafite ubushobozi bwo kureba busanzwe (20/20) . Gusuzuma amaso bishobora kugaragaza ibibazo ushobora kuba utazi cyangwa utabona. Amakosa yo kureba kure , nko kureba hafi (Myopia) cyangwa kureba kure (Hyperopia), ashobora gutera ububabare bwo kureba uko igihe kigenda. Rero ushobora kutabibona mbere na mbere. Gusuzuma amaso bishobora gufata ibi bibazo mbere yuko ubimenya.

• Rinda amaso yawe: Ni ngombwa kwambara ubwirinzi bw'amaso mu gihe hari ibyago byo kwangirika kw'amaso. Indorerwamo z'indorerwamo cyangwa indorerwamo , udupfukamunwa two mu maso cyangwa udukingirizo bishobora gufasha muri ibi. Urugero, niba urimo gusudira, ukata ibiti, cyangwa ukoresha ifu mu rugo, ibi ni ingenzi cyane. Indorerwamo z'izuba nazo ni uburyo bwiza bwo kurinda amaso yawe. Zirinda amaso yawe imirasire ya UV yangiza.Irinda. Kubera ko izuba muri Sri Lanka rikaze cyane, ni byiza cyane gukoresha indorerwamo z'izuba.

• Wite ku mirire yawe: Amaso yawe akeneye vitamine n'intungamubiri zimwe na zimwe kugira ngo akore neza. Niba ufite ikibazo kuri ibi, ushobora kugisha inama muganga w'umuryango wawe cyangwa inzobere mu by'amaso. Kurya indyo yuzuye ni ingenzi cyane.

• Shyira imbere imyitozo ngororamubiri: Ubuzima bw'amaso yawe ni ikimenyetso cy'ubuzima bwawe muri rusange. Imyitozo ngororamubiri ihoraho no gukomeza gukora siporo bishobora gufasha amaso yawe (n'umubiri wawe wose) kugira ubuzima bwiza.

• Irinde kunywa itabi: Kunywa itabi, kunywa itabi rya vape, no gukoresha itabi ridafite umwotsi bishobora kugira ingaruka mbi ku buzima bwawe no ku maso yawe. Kureka ibi bintu, cyangwa kutabitangira burundu, bishobora kugira ingaruka zikomeye.

• Niba uhuye n'impinduka zitunguranye mu kureba kwawe cyangwa kutabona neza, shaka ubufasha bwa muganga ako kanya, ntutinde: Ibi bishobora kuba ibimenyetso by'ikibazo gikomeye. Gutakaza ubushobozi bwo kureba butunguranye ni impamvu yo gushaka ubufasha kwa muganga. Niba ufite ikibazo gishobora gutuma ubona ibintu mu buryo butunguranye, muganga wawe cyangwa umuganga w'amaso azakubwira igihe ugomba gushaka ubuvuzi bwihariye.

Igikuru ni ukwita ku maso yawe. Nubona impinduka nto, ntuzirengagize.

Incamake: Ibintu byo kwibuka

Ku bantu benshi, kureba ni bwo buryo bw'ingenzi bakoresha buri munsi. Nubwo bishobora gusa n'aho ari ubushobozi bworoshye, mu by'ukuri ni kimwe mu bintu bigoye cyane mu mibiri yacu. Kugira ngo amaso yawe akore neza, buri gice cy'ijisho ryawe, harimo retina, imitsi y'amaso, n'ubwonko, byose bigomba gukorana neza.

Ku bw'amahirwe, hari ibintu byinshi ushobora gukora kugira ngo urinde kandi ukomeze aya maso y'agaciro. Hanyuma, aho guhangayikishwa n'ibyo ubona cyangwa utabona, ushobora kwishimira kureba ibintu wifuza kubona. Noneho, tangira kwita ku maso yawe uyu munsi!
