Imizimba yethu ihlala ezinkulungwaneni zezigidi zezinhlobo zemithi. Ama-microorganisms athola imizimba yethu ekhululekile, futhi sinemifino evamile yebhaktheriya, i-fungus, kanye nama-virusi, okuyinhloko, okwandisa ikhwalithi yethu yokuphila nempilo. Nokho, ngezinye izikhathi, ukunqwabelana kwamagciwane noma ukuhlasela kwegciwane ukuthi imizimba yethu ayithandi ngokudala izifo ezingasongela empilweni yethu futhi zingalimaza umbono wethu kanye nempilo yeso.
Siyazi isikhathi esithile ukuthi abathwali be- lens abathintekayo banengozi engaba ngu-15 engozini yokuthola izifo zesohlo kunabathwali be-lens abangekho othintana nabo. Ngaphandle kokuxhaphazwa kwe-lensi ngeminwe yethu, abacwaningi babengacacile ngaso sonke isikhathi ukuthi isimo se-bacterial esweni sishintsha kanjani lapho sigqoka amalensi oxhumana nabo. Kodwa-ke, abacwaningi base-NYU baqedela ucwaningo olwenziwe emhlanganweni waminyaka yonke we-American Society for Microbiology ngoMeyi 2015 okwenza kube lula ukuhlukana kwezinhlobo namanani ezincane ezincane ezingase zikhona kulabo abathintekayo be-lens ngokubhekelana no-non-contact lens abathwali.
Isifundo SeBactterial
Amakhulu ama-swabs ezinxenyeni ezihlukene zeso athathwa ngesikhathi sokutadisha. Ukuhlaziywa kwalezi swabs kwavumela ithimba ukuthi lifunde ukuthi yiziphi izinhlobo zama-bacterium akhona. Ucwaningo luhlanganisa nabantu abangu-20. Abayisishiyagalolunye kulabo ababambiqhaza babegqoke ama-lensi okuxhumana nabo futhi abasele babengenzi. Ososayensi bathatha amakhulu ama-swabs esikhumba eseduze kweso , izingxenye zeso ngokwalo futhi basebenzisa amalensi othintana nabo.
Lezi swabs zahlaziywa ebhokisithri ukuze zibale ukuthi zingaki ama-bacterium ahlukene ekhona.
Ngemva kokuhlaziya imiphumela, abacwaningi bathola kathathu inombolo evamile yamabhaktheriya i- Methylobacterium , i- Lactobacillus , i- Acinetobacter ne- Pseudomonas emehlweni alabo abathintekayo be-lens. Babonisa ukuthi i-microbiome iso ifana ne-microbiome yesikhumba kunokuba yeso elijwayelekile.
Lolu lwazi lungabalulekile ekusizeni ososayensi baqonde ukuthi kungani abathwali be-lens abathintana nabo bengabhekana nokutheleleka kwamehlo kunabathwali bokungena othintana nabo. Kungasiza futhi ososayensi banqume ukuthi ukwanda kwezifo ezithinta amehlo kubantu abagqoke amalensi okuxhumana kungenxa yeminwe ethinta iso noma amalensi oxhumana nabo ngokuqondile axhumane naso.
Kodwa-ke, abacwaningi bakhomba okuthile ababengalindele ukuthola. Ngenkathi i-microbiome ye-eye emithwaleni ye-lens yokuxhumana ihlanganisa amabhaktheriya angabungozi esingabajwayele kakhudlwana esikhumbeni sethu, ucwaningo lwabonisa ukuthi izinhlobo ezingu-5 245 zama-bacterium kanye nama-subtypes zitholakala emehlweni abathwali be-lens. Futhi kutholakale izinhlobo ezingu-2 133 esikhumbeni ngqo ngaphansi kwabathwali be-lens, kanti izinkinga ezihlukahlukene ezingu-3,839 zitholakale kubathwali abangenawo oxhumana nabo. Ngokuthakazelisayo, abacwaningi babala futhi amabhaktheriya amaningi aseStaphylococcus , ahlobene nokutheleleka kwamehlo futhi akhombisa ngokweqile esikhumbeni sethu, emehlweni abathwali bezinsimbi ezingathintana nabo. Bavuma ukuthi kwakumangalisa ukubona lokhu kungalingani. Ngokufingqa, abathwali be-lens abathintekayo babe nama-bacteria ambalwa, kodwa uhlobo lwamabhaktheriya olutholakala lungaba yingozi kakhulu empilweni yamehlo .
Amathiphu Okuvimbela Ukutheleleka
Njengazo zonke izifundo, ucwaningo olwengeziwe luyadingeka ukuze kucacise idatha. Kodwa-ke, kugcizelela ukuthi abathintekayo be-lens kumele baqaphele amehlo abo kanye nokuhlanza izandla . Umuntu anganciphisa kalula ingozi yokutheleleka yilokhu okulandelayo:
- Geza izandla zakho ngesepha namanzi. Yima izandla zakho ngokuphelele ngaphambi kokuthinta amalensi akho oxhumana naye.
- Ngisho noma ngabe kunqunywe i-lens e-FDA-evunyelwe ukulala kuyo, nciphisa inani lezinsuku olala ngazo kuma-lensi oxhumana nabo.
- Gwema ukubhukuda ngama-contact lens kanye nokufaka ama-tubs okushisayo nama-contact lens. Futhi, gwema ukugqoka ama-lens angama-contact uma uthola emanzini anamaqabunga noma ama-brackish.
