Kodi khungu khungu ndi chiyani?

Khungu lakhungu limachitika mavuto amtundu wa diso m'maso amabweretsa zovuta kapena kulephera kusiyanitsa mitundu.

Anthu ambiri omwe ali obiriwira samatha kusiyanitsa pakati pa ofiira ndi obiriwira. Kusiyanitsa zachikasu ndi blues kungakhalenso kovuta, ngakhale mtundu wamtundu wakhunguwu siwofala.

Chikhalidwechi chimakhala chofatsa mpaka choopsa. Ngati ndinu wakuda kwathunthu, womwe ndi matenda otchedwa achromatopsia, mumangowona mwa imvi kapena wakuda ndi woyera. Komabe, matendawa ndi osowa kwambiri.

Anthu ambiri omwe ali ndi khungu losawona amawona mitundu yotsatirayi m'matundu amtundu m'malo mwa reds, amadyera, ndi tiyi omwe ena amawona:

  • wachikasu
  • imvi
  • beige
  • buluu

Kodi khungu lodziwika bwino ndilofala motani?

Khungu lakhungu ndilofala kwambiri mwa amuna.Amayi amatha kunyamula chromosome yolakwika yomwe imayambitsa kufalitsa khungu, koma amuna nthawi zambiri amakhala olowa.


Malinga ndi American Optometric Association, pafupifupi 8% ya azungu azungu amabadwa ndi vuto lakuwona mitundu poyerekeza ndi 0,5% ya akazi amitundu yonse.

2014 yokhudzana ndi khungu kumamwera kwa ana asukulu yakumwera kwa California idapeza kuti kusowa kwamaso kumafala kwambiri mwa ana omwe si Azungu komanso osafala kwambiri mwa ana akuda.

Achromatopsia imakhudza munthu m'modzi mwa anthu 30,000 padziko lonse lapansi. Mwa awa, mpaka 10 peresenti sazindikira mtundu uliwonse.

Kodi zizindikiro zakhungu khungu ndi ziti?

Chizindikiro chodziwika kwambiri chakhungu lakhungu ndikusintha kwamasomphenya anu. Mwachitsanzo, kungakhale kovuta kusiyanitsa pakati pa ofiira ndi obiriwira a magetsi. Mitundu imatha kuwoneka yosawala kuposa kale. Mitundu yosiyanasiyana yamitundu imatha kuwoneka yofanana.

Khungu lakhungu nthawi zambiri limawoneka ali aang'ono pomwe ana akuphunzira mitundu yawo. Kwa anthu ena, vutoli silimadziwika chifukwa aphunzira kuyanjanitsa mitundu inayake ndi zinthu zina.


Mwachitsanzo, amadziwa kuti udzu ndi wobiriwira, motero amatcha utoto womwe amawona wobiriwira. Ngati zizindikiro ndizofatsa kwambiri, munthu sangazindikire kuti samawona mitundu ina.

Muyenera kufunsa adotolo ngati mukukayikira kuti inu kapena mwana wanu ndinu wakhungu. Adzatha kutsimikizira kuti ali ndi matendawa ndikuchotsanso mavuto ena azaumoyo.

Kodi mitundu yakhungu yakhungu ndi iti?

Pali mitundu itatu yayikulu yakhungu lakhungu.

Mu mtundu umodzi, munthuyo amavutika kusiyanitsa zofiira ndi zobiriwira. Mu mtundu wina, munthuyo amavutika kusiyanitsa chikaso ndi buluu.

Mtundu wachitatu umatchedwa achromatopsia. Munthu amene ali ndi mawonekedwewa sangathe kuzindikira mtundu uliwonse - chilichonse chikuwoneka chotuwa kapena chakuda komanso choyera. Achromatopsia ndiye mtundu wodziwika kwambiri wakhungu.

Khungu lakhungu limatha kutengera kapena kutengera.

Khungu lobadwa nalo

Khungu lobadwa nalo ndilofala kwambiri. Ndi chifukwa cha vuto la chibadwa. Izi zikutanthauza kuti vutoli limadutsa m'banja. Wina yemwe ali ndi abale ake apamtima omwe ali obiriwira amatha kukhala ndi vutoli.


Khungu losawoneka bwino

Khungu lodziwika bwino limayamba pambuyo pake ndipo limatha kukhudza amuna ndi akazi chimodzimodzi.

Matenda omwe amawononga mitsempha ya optic kapena diso la diso amatha kuyambitsa khungu. Pachifukwachi, muyenera kuchenjeza dokotala wanu ngati masomphenya anu asintha. Zitha kuwonetsa vuto lalikulu.

Nchiyani chimayambitsa khungu khungu?

Maso amakhala ndi timitsempha ta minyewa timene timathandiza kuti diso, lomwe ndi chingwe chosawalira pang'ono kumbuyo kwa diso lako, lizitha kuona mitundu.

Mitundu itatu yosiyanasiyana ya ma cones imatenga kuwala kwa mitundu yosiyanasiyana, ndipo mtundu uliwonse umachita ngati wofiira, wobiriwira, kapena wabuluu. Ma cones amatumiza chidziwitso kuubongo kuti adziwe mitundu.

Ngati imodzi kapena zingapo zamtunduwu mu diso lanu zawonongeka kapena kulibe, mudzakhala ovuta kuwona mitundu moyenera.

Chibadwa

Zambiri zakusowa kwamitundu ndizotengera. Nthawi zambiri zimachokera kwa mayi kupita kwa mwana. Khungu lobadwa nalo silimayambitsa khungu kapena kutayika kwina.

Matenda

Muthanso kukhala ndi khungu chifukwa cha matenda kapena kuvulala kwa diso lanu.

Ndi glaucoma, kuthamanga kwamkati kwa diso, kapena kuthamanga kwa intraocular, ndikokwera kwambiri. Kupanikizika kumawononga mitsempha ya optic, yomwe imanyamula zisonyezo kuchokera m'diso kupita ku ubongo kuti mutha kuwona. Zotsatira zake, kuthekera kwanu kusiyanitsa mitundu kumatha kuchepa.

Malinga ndi magazini ya Investigative Ophthalmology & Visual Science, kulephera kwa anthu omwe ali ndi glaucoma kusiyanitsa buluu ndi chikaso kwadziwika kuyambira kumapeto kwa zaka za zana la 19.

Kuperewera kwamatenda ndi matenda ashuga retinopathy kumawononga diso, komwe kumakhala ma cones. Izi zitha kuyambitsa khungu khungu. Nthawi zina, zimayambitsa khungu.

Ngati muli ndi ng'ala, diso la diso lanu limasintha pang'onopang'ono kuchoka poyera kupita pa opaque. Maso anu amatha kuchepa chifukwa cha izi.

Matenda ena omwe angakhudze masomphenya ndi monga:

  • matenda ashuga
  • Matenda a Parkinson
  • Matenda a Alzheimer
  • matenda ofoola ziwalo

Mankhwala

Mankhwala ena amatha kusintha mawonekedwe. Izi zimaphatikizapo mankhwala a antipsychotic chlorpromazine ndi thioridazine.

Maantibayotiki ethambutol (Myambutol), omwe amachiza chifuwa chachikulu, amatha kuyambitsa mavuto amitsempha yamagetsi ndikuwona zovuta mitundu ina.

Zinthu zina

Khungu khungu mwina chifukwa cha zinthu zina. Chimodzi mwa zinthu ndi ukalamba. Kutaya masomphenya ndi kuchepa kwa utoto kumatha kuchitika pang'onopang'ono ndi ukalamba. Kuphatikiza apo, mankhwala owopsa monga styrene, omwe amapezeka m'mapulasitiki ena, amalumikizidwa ndikulephera kuwona utoto.

Kodi khungu lakuda limapezeka bwanji?

Kuwona mitundu ndiyodalira. Ndizosatheka kudziwa ngati mumawona ofiira, amadyera, ndi mitundu ina chimodzimodzi ndi anthu omwe ali ndi masomphenya abwino. Komabe, dokotala wanu wamaso amatha kuyesa ngati ali ndi vuto loyesedwa.

Kuyesedwa kudzaphatikizapo kugwiritsa ntchito zithunzi zapadera zotchedwa mbale za pseudoisochromatic. Zithunzizi ndizopangidwa ndimadontho achikuda omwe ali ndi manambala kapena zizindikilo zolowetsedwa mkati mwake. Anthu okha omwe ali ndi masomphenya abwinobwino amatha kuwona manambala ndi zizindikilozi.

Ngati ndinu akhungu, mwina simungawone nambala kapena mutha kuwona nambala ina.

Ndikofunika kuti ana ayesedwe asanayambe sukulu chifukwa zida zambiri zamaphunziro aubwana zimaphatikizapo kuzindikira mitundu.

Kodi anthu akhungu lakhungu ndi otani?

Ngati khungu lakhungu limachitika chifukwa chodwala kapena kuvulala, kuthana ndi chomwe chimayambitsa kungathandize kukonza utoto.

Komabe, palibe mankhwala ochiritsira khungu khungu. Dokotala wanu wa diso angakupatseni magalasi achikuda kapena magalasi omwe angakuthandizeni kusiyanitsa mitundu.

Anthu omwe amakonda khungu nthawi zambiri amagwiritsa ntchito njira zina kapena amagwiritsa ntchito zida zina kuti moyo ukhale wosavuta. Mwachitsanzo, kuloŵeza dongosolo la magetsi kuchokera pamwamba mpaka pansi pamaloboti kumachotsa kufunika kosiyanitsa mitundu yake.

Kulemba zovala kumatha kuthandizanso mitundu yofananira. Mapulogalamu ena amasintha mitundu ya makompyuta kukhala ija yomwe anthu obala khungu amatha kuwona.

Khungu lobadwa nalo ndilovuta kwa moyo wanu wonse. Ngakhale zimatha kuchepetsa chiyembekezo cha ntchito zina, monga kugwira ntchito yamagetsi yemwe amayenera kusiyanitsa mawaya okhala ndi utoto, anthu ambiri amapeza njira zothetsera vutoli.
