Guhuza amaso n'ikiganza bivuga ubushobozi bwo gutunganya amakuru yakirwa binyuze mu maso kugira ngo ugenzure, uyobore kandi uyobore ingendo z'intoki.
Astaxanthin, lutein na zeaxanthin ni intungamubiri za carotenoid zizwiho kugira akamaro ku buzima bw'amaso.
Kugira ngo hakorwe ubushakashatsi ku ngaruka zo kongeramo izi ntungamubiri eshatu ku mirire ku guhuza amaso n'intoki no gukurikirana neza amaso nyuma y'ibikorwa bya VDT, hakozwe igerageza rya muganga ryakozwe ku buryo bworoshye kandi bugenzurwa na placebo.
Kuva ku ya 28 Werurwe kugeza ku ya 2 Nyakanga 2022, Ishyirahamwe ry’Ubuyapani rishinzwe Siporo muri Tokyo ryakoze ubushakashatsi ku bagabo n’abagore b’Abayapani bafite ubuzima bwiza bari hagati y’imyaka 20 na 60. Abakoreweho ubushakashatsi bari bafite amaso areba kure ya 0.6 cyangwa irenga mu maso yombi kandi bakinaga imikino ya videwo buri gihe, bakoreshaga mudasobwa, cyangwa bakoreshaga VDT mu kazi.
Abantu 28 na 29 bose hamwe bashyizwe mu matsinda yakozwe n’abahawe imiti igabanya ubukana bw’indwara (placebo) n’abahawe imiti igabanya ubukana bw’indwara (allergy).
Itsinda ryakoze ryahawe imiti igabanya ubukana irimo astaxanthin 6mg, lutein 10mg, na zeaxanthin 2mg, mu gihe itsinda rya placebo ryahawe imiti igabanya ubukana irimo amavuta y’umuceri. Abarwayi bo mu matsinda yombi bafashe iyi miti inshuro imwe ku munsi mu gihe cy’ibyumweru umunani.
Imikorere y'amaso n'ubucucike bw'amabara ya macular pigment optical (MAP) byapimwe ku ikubitiro no mu byumweru bibiri, bine, n'umunani nyuma yo kongerwamo.
Igikorwa cy'abitabiriye VDT cyari kigizwe no gukina umukino wa videwo kuri telefoni igendanwa mu gihe cy'iminota 30.
Nyuma y'ibyumweru umunani, itsinda ry'ibikorwa ryagize igihe gito cyo guhuza amaso n'intoki (amasegonda 21.45 ± 1.59) ugereranije n'itsinda rya placebo (amasegonda 22.53 ± 1.76). googletag.cmd.push(function () { googletag.display('text-ad1′); });
Byongeye kandi, uburyo bwo guhuza intoki n'amaso nyuma ya VDT mu itsinda ryakoraga (83.72±6.51%) bwari hejuru cyane ugereranyije n'itsinda ryakoreweho placebo (77.30±8.55%).
Byongeye kandi, habayeho ukwiyongera gukomeye kwa MPOD, ipima ubucucike bwa retina (MP), mu itsinda rikora. MP igizwe na lutein na zeaxanthin, bikura urumuri rw'ubururu rwangiza. Uko irushaho kuba nini, niko ingaruka zayo zo kuyirinda zirushaho gukomera.
Impinduka mu rugero rwa MPOD uhereye ku ntangiriro no nyuma y'ibyumweru umunani zari hejuru cyane mu itsinda ryari rikora (0.015 ± 0.052) ugereranije n'itsinda rya placebo (-0.016 ± 0.052).
Igihe cyo gusubiza ku bintu bitera visuo-motor, nk'uko byapimwe no gukurikirana neza ingendo z'amaso, ntabwo cyagaragaje iterambere rigaragara nyuma yo kongerwamo muri buri tsinda.
Umwanditsi yagize ati: “Ubu bushakashatsi bushyigikira igitekerezo cy’uko imikorere ya VDT ibangamira by’igihe gito imikorere y’amaso n’intoki ndetse no gukurikirana neza amaso, kandi ko kongeramo astaxanthin, lutein, na zeaxanthin bifasha kugabanya imikorere y’amaso n’intoki bitewe na VDT.”
Gukoresha VDTs (harimo mudasobwa, telefoni zigendanwa na tableti) byahindutse igice gisanzwe cy'ubuzima bwa none.
Nubwo ibi bikoresho bitanga uburyo bworoshye, byongera imikorere, kandi bikagabanya kwigunga mu bandi, cyane cyane mu gihe cy'icyorezo, ubushakashatsi butandukanye bwagaragaje ko gukora VDT igihe kirekire bishobora kugira ingaruka mbi ku mikorere y'amaso.
Abanditsi bongeyeho bati: “Bityo rero, dutekereza ko imikorere y’umubiri idakora neza bitewe n’imikorere ya VDT ishobora kugabanya imikoranire y’amaso n’amaboko, kuko ubusanzwe ibyo bifitanye isano n’ingendo z’umubiri.”
Dukurikije ubushakashatsi bwakozwe mbere, astaxanthin yo mu kanwa ishobora kugarura aho amaso ahagaze no kunoza ibimenyetso by'imitsi n'amagufwa, mu gihe lutein na zeaxanthin byavuzwe ko byongera umuvuduko wo gutunganya amashusho no kugaragaza itandukaniro ry'imiterere y'umubiri, byose bigira ingaruka ku mikorere ya visuomotor.
Byongeye kandi, hari ibimenyetso bigaragaza ko imyitozo ngororamubiri ikomeye ibangamira ubushobozi bwo kubona ibintu mu mpande z'umubiri binyuze mu kugabanya umwuka wa ogisijeni mu bwonko, ibi bikaba bishobora kwangiza uburyo amaso n'amaboko bikorana.
Abanditsi basobanura bati: “Kubera iyo mpamvu, gufata astaxanthin, lutein, na zeaxanthin bishobora no gufasha kunoza imikorere y’abakinnyi nka tennis, baseball, na esports.”
Byari bikwiye kumenyekana ko ubushakashatsi bwari bufite imbogamizi zimwe na zimwe, harimo no kutagira imirire ibuza abitabiriye. Ibi bivuze ko bashobora kurya intungamubiri mu gihe cyo kurya buri munsi.
Byongeye kandi, ntibiramenyekana neza niba ibisubizo ari inyongeramusaruro cyangwa ingaruka zihuriweho z’intungamubiri zose uko ari eshatu aho kuba ingaruka z’intungamubiri imwe.
Abanditsi basoje bagira bati: “Twizera ko guhuza izi ntungamubiri ari ingenzi cyane mu kugira ingaruka ku mikoranire y’amaso n’intoki bitewe n’uburyo butandukanye bwo gukora. Ariko, hakenewe ubundi bushakashatsi kugira ngo hamenyekane uburyo bw’ingaruka nziza ziterwa n’izi ntungamubiri.”
"Ingaruka za astaxanthin, lutein, na zeaxanthin ku guhuza amaso n'ibiganza no gukurikirana amaso neza nyuma yo gukora isuzuma ry'amaso ku bantu bazima: igerageza ryakozwe ku buryo butunguranye, ritabona kabiri, rigenzurwa na placebo".
