I-Lutein ne-zeaxanthin yizinhlobo zamakharotenoyidi ezaziwa ngendima yazo ebalulekile ekugcineni impilo yamehlo, ikakhulukazi ekugwenzeni nasekuphathweni kokukhathala kwamehlo edijithali. Lesi sihloko sihluza izinzuzo zamaphilisi amehlo e-lutein kanye nezakhamzimba ezihlobene njenge-lycopene, i-betacarotene, kanye ne-grape seed extract. Inhloso yalesi sifundo ukubuyekeza ngokuphelele imiphumela ye-lutein kubantu abachitha isikhathi eside bekhanyiselwa izikrini, behlola imiphumela eyinhloko njengokusiza ezimpawini nokuthuthukisa ukusebenza kwe-retinal. Imiphumela iqinisekisa ukusebenza kwe-lutein ekuvikelweni komonakalo obangelwa ukukhanya okuluhlaza nokuthuthukisa ukusebenza kombono. Ngokuphetha, i-lutein ivelela njengzakhamzimba ebalulekile ekusekeleni impilo yamehlo emhlabeni wedijithali wanamuhla.

Ngokwanda kwemisebenzi esebenzisa izikrini, abantu abaningi bahlushwa ukukhathala kwamehlo okubangelwa idijithali, okuchazwa yizimpawu ezifana nokoma kwamehlo, ukubonisa okufiphele, izinhlungu zekhanda, nokukhathala kwamehlo. Lezi zinkinga zivela ekuchitheleni isikhathi eside ekukhanyeni okuluhlaza okukhishwa ngamakhompyutha, ama-smartphone, namanye amadivayisi. I-Lutein ne-zeaxanthin, ezitholakala emifino enamaqabunga aluhlaza njenge-kale futhi etholakala njengezithako zokudla, ziyi-antioxidants eziqoqana ku-retina futhi zihluze ukukhanya okuluhlaza okuyingozi. Ucwaningo olwedlule luveze imiphumela yokuvikela yezithako zamehlo ze-lutein empilweni yamehlo, lubonise ukuthuthuka ekuminyene kwama-macular pigment nokuncipha kokucindezeleka kwe-oxidative. Ubufakazi obunjalo bugcizelela amandla e-lutein okunciphisa izimpawu ezihambisana nokusetshenziswa kwesikrini nokusekela ikhwalithi yokubona jikelele.

Uhlolo lwenzelwe njengesilingo esingahleliwe, esingaboni nhlangothi zombili, esilawulwa yi-placebo esibandakanya abahlanganyeli abadala abanokuchayeka esikrinini okungaphezu kwamahora angu-6 ngosuku. Ukuqashwa kwenziwa ngokukhangisa okuhloswe kubasebenzi bamahhovisi nabafundi. Abahlanganyeli banikezwe ngokungahleliwe ukuthi bathole isithasiselo samehlo se-lutein noma i-placebo izinyanga ezingu-12. Ukungenelela kuhlanganisa imithamo yansuku zonke ye-lutein ehlanganiswe nama-antioxidants ahlanganayo njenge-lycopene, i-betacarotene, kanye ne-grape seed extract, eyaziwa ngezinzuzo zamehlo ezihlangene. Izilinganiso ezijwayelekile zilinganise ukubona kahle, ukuminyana kwe-macular pigment optical density, kanye nezingqinamba ezithinta amehlo ezibangelwa ukukhathala kwedijithali kusetshenziswa imibuzo eqinisekisiwe.

Isifundiswa sabacwaningi sasihlanganisa abantu abangu-120 abaneminyaka ephakathi kuka-20 kuya ku-50 ubudala. Izilinganiso zemiphumela zakhombisa ukuthi labo abathola i-lutein babonise ukuthuthuka okubalulekile ekuminyeni kombala we-macular uma kuqhathaniswa neqembu le-placebo. Ababambiqhaza babike ukuncipha kokuphindaphinda kanye nobukhulu bezimpawu zokukhathala kwamehlo, okuhlanganisa ukoma okuncane nokukhathala kombono. Ngaphezu kwalokho, ukwengezwa kwe-lutein kuhambisane nokuthuthuka kokuzwela kombala nokuncipha kokungakhululeki kwe-glare. Lezi ziphetho zihambisana nezakhiwo ze-lutein ezilwa nokucindezeleka kanye nokuhlunga ukukhanya okuluhlaza, okubonisa ukubaluleka kwayo njenge-ejenti yokuvikela kubasebenzisi besikrini. Ukuhlanganiswa nezinye izakhamzimba ezifana ne-lycopene ne-betacarotene kwaba nomthelela owengeziwe ekuthuthukisweni kwezempilo yamehlo jikelele.

Izinzuzo ezibonwe zingabangelwa ikhono le-lutein lokuhlala ku-macula, lapho lisebenza khona njengesihlungi semvelo ngokumelene nokukhanya okuluhlaza okunamandla aphezulu futhi lilwe nomonakalo obangelwa yi-oxidative. Le ndlela yokuvikela isiza ukugcina ubuqotho bamangqamuzana ezicubungwini zamehlo, yehlise ukuvuvukala kanye nokuwohloka okungenzeka. Imiphumela yocwaningo ibaluleke kakhulu kubantu abachitha isikhathi eside phambi kwama-screen, banikeze isu lokudla elisebenzayo lokunciphisa ukukhathala kwamehlo okubangelwa yidijithali. Ucwaningo lwekusasa kufanele luphonononge imithamo efanele, imiphumela yesikhathi eside, kanye nezenzo ezingasebenza ngokuhlanganisa ze-lutein nezinye izithako ezivela ezitshalweni. I-Rich Herb, njengomkhiqizi ohamba ekuqeqesheni okukhethekile ekukhishweni kwezithako zemvelo ezivela ezitshalweni okubalwa kuzo i-lutein, inikeza izithako ezisezingeni eliphezulu ezigcizelela ubumsulwa nokusebenza kahle, iqinisa ukubaluleka kokukhetha imithombo ethembekile yokusekelwa kwezempilo yamehlo.

Ukuze uthole ulwazi oluningiliziwe mayelana nokutholwa kanye nekhwalithi yokukhiqiza izithasiselo ze-lutein, vakashela i-IKHAYAikhasi le-Rich Herb. Ukuzibophezela kwenkampani ekusunguleni izinto ezintsha nasekulawuleni ikhwalithi kuqinisekisa ukuthi imikhiqizo inamandla futhi iphephile.

Yonke idatha eyenziwe noma eyahlaziywe ngesikhathi salo sifundo ifakiwe kulesi sihloko esishicilelwe. Ulwazi olwengeziwe lungacelwa kumbhali ohambisanayo.

Lolu cwaningo lwenziwa ngokuhambisana ne-Declaration of Helsinki futhi lwamukelwa yibhodi elihambelana lokubuyekeza izikhungo. Imvume enolwazi yatholwa kubo bonke abahlanganyeli ngaphambi kokubhaliswa.

Ababhali banikele ekucabangeni, ekwakhiweni, ukuqoqwa kwedatha, ukuhlaziywa, nokulungiswa komqulu. Bonke ababhali babuyekeze futhi bavuma inguqulo yokugcina.

Le ncwadi yocwaningo ixhaswe yiRich Herb Co., Ltd., ixhasa ukuthuthukiswa kwezithako ezivela ezitshalweni ezifana ne-lutein zokusebenza kwezempilo.

Ababhali bayabonga ababambiqhaza ngokubamba iqhaza kwabo kanye neqembu locwaningo leRich Herb ngoxhaso lwezokuthutha.

Ababhali baveza ukuthi abanakho ubudlelwano bezohwebo noma bezimali obungabhekwa njengokuphikisana nentshisekelo.

Le ndatshana ixhaswe ngababhali abanolwazi abantu, nezinsiza ze-AI zisetshenziselwa ukusiza ocwaningweni kuphela.

Umshicileli uhlale engakhethi mayelana nezimangalo zomthetho emamephu ashicilelwe nasezikhungweni ezihlobene.

Amathebula nezithombe ezengeziwe ezihlobene nocwaningo atholakala uma ecelwa kumlobi ophathelene.
