Namuhla, ukusetshenziswa kwamalensi okuxhumana kuyindlela evamile yokulungiswa kombono , okufanelwe ukuncintisana nokusetshenziswa kwezibuko. Ama-lense ahlukaniswa ngokuvumelana nezici ezithile, kufaka phakathi isikhathi sokuhlelwa kwawo okuhlelwe (indlela yokugqoka): usuku olulodwa, isonto elibili, inyangazonke, isigamu sonyaka, njll. Ngokuphathelene nama-lens okuphi okudingekayo ukunikeza impilo, ukuphikisana okuningi kuyaqhubeka, Ama-lens anabo abathandayo. Ake sizame ukubona ukuthi yiziphi izinhlobo ezimbili ezivamile zama-lensi okungcono - usuku olulodwa noma ngenyanga.
Yini ehlukanisa amalensi amalanga owodwa kusukela esikhathini sokuya esikhathini?
Ama-lens wokugqoka njalo ngenyanga amalensi othintana nabo abathintekayo bokusetshenziswa okuvuselelwa ngokuphila kwezinsizakalo kwezinsuku ezingu-30. Ngemuva kwalesi sikhathi, ama-lens adinga ukufakwa esikhundleni esisha. Njengomthetho, lezo zeso zeso zigqoke ekuseni, futhi ngaphambi kokulala, zisuswe ngokuzifaka esitsheni ngesisombululo esikhethekile sokugcina. Futhi kukhona ama-lensi okugqoke isikhathi eside, okungahle kugqoke ngaphandle kokuphazanyiswa ubusuku. Kodwa kubalulekile ukucabangela ukuthi akuzona zonke izilonda futhi akuzona zonke iziguli ezingagqoka njalo ngenyanga - kwezinye izimo kunconywa ukuthatha ikhefu ngobusuku obunye emva kwezinsuku eziyisithupha noma elinye igama.
Zenziwe ngezinto ezihlinzeka ngobuso obushelelezi, izinga elanele lomswakama, ukushintshaniswa kwe-oxygen, futhi nokuvimbela ukungcola okusheshayo kwamalensi ngamaprotheni amadiphozi. Ngakho-ke, ama-lenti anezinsiza zokusebenza zenyanga zonke akhululekile, akhululekile amehlo futhi awadingi ukuhlanza okujulile kwe-enzymatic. I-lens yokuxhumana yenyanga yindlela ekhethiwe yokonga kulabo abanezinkinga zombono abazisebenzisa njalo, nsuku zonke.
Amalensi amalanga owodwa adinga ukuguqulwa njalo amahora angu-24. Zithengiswa emaphaketheni amakhulu ama-30-90 izingcezu futhi zenziwe ngamanye izinto eziningana ezingafani nokuqina. Ngesikhathi esifanayo, amadivaysi anjalo asebenza ngokugcwele nemisebenzi yawo. Ngokungafani nenyanga zonke, ilensi eyodwa yosuku lunezimo eziguquguqukayo, ezithambile futhi ezincane. Ngaphezu kwalokho, zibhekene nezinga eliphakeme lokuphefumula kwe-oxygen, okwenza kube lula ukuwasebenzisa ngisho nasesweni elibucayi kakhulu. Ezinye izinzuzo ezihlukile zamalensi ezinesikhathi esisodwa sokusetshenziswa yizi:
- Ukuthobeka - uma usebenzisa amalensi anjalo ufake i-pair entsha, oyinyumba nsuku zonke, ngakho-ke ingozi yokuhlukunyezwa kwamehlo iyancipha kakhulu;
- Asikho isidingo sokunakekelwa okukhethekile - ilensi yelanga elilodwa liphonswa ngaphandle kokuphila komsebenzi wabo futhi akudingi ukusetshenziswa kwezihlungi ezikhethekile, izifo ezibulala amagciwane, izixazululo zokugcina, ezenza kube lula ukusetshenziswa kwazo;
- Ukuqeda ukusetshenziswa okuphoqelelwe kwama-lens abonakalisiwe - ukungabi namalenze okungahlali njalo okungenzeka ngisho nangemva kwezinsuku ezimbalwa zokugqoka, kungabonakala, ngakho-ke ngezinye izikhathi iziguli zisebenzisa amadivaysi abonakalisiwe,
ekwazi ukulimaza ngokungaqondakali i-cornea, futhi uma ugqoke ama-lens we-day-day lokhu kukhishwe.
Yiqiniso, zonke lezi zinzuzo ziboniswa izindleko zosuku olulodwa olugqoke ama-lens. Kodwa nokho akuyona ephakeme kakhulu kunamanani lensenti yenyanga, enikezwe ukuthi lokhu okudinga ukuthenga kwemikhiqizo yokwengamela eyengeziwe.
Ngingakwazi ukulala ngamalensi amalanga owodwa?
Ochwepheshe abaningi bayavuma ukuthi kuyadingeka ukususa amalensi ebusuku, ngisho nosuku olulodwa. Uma kungenjalo ekuseni ngeke uthole nje ukuzwa okungazwakalayo njengokumisa noma ukugcoba kwamehlo, umbono obonakele, kodwa futhi nokuzibandakanya nezinye izifo.
