Ixosha izinhlayiya zothuli ukuze zibone kahle futhi kulula ukuwahlanza amalensi
Ixosha ama-smudges akhathazayo ukuze kube nokucaca okubonakalayo kanye namalensi okuhlanza kalula
Ukuqinisekisa umbono ocacile, oqinisekisiwe iminyaka emi-2 (1)
Ivikela amehlo akho emisebeni ye-UVA ne-UVB
Ixosha amaconsi amanzi ukuze amalensi akho ahlale ecacile
Izinto ezingcono kakhulu ezilinganiselayo zelensi ephezulu enesabelo esikhulu kunazo zonke semakethe yezinto ezibonakalayo zelensi ye-refractive 1.60. I-MR-8 ifaneleka kunoma iyiphi ilensi yamehlo yamandla futhi iyindinganiso entsha kumalensi we-ophthalmic.
Inombolo ye-Abbe: Inombolo enquma ukunethezeka kokubuka kwezibuko
UMR-8 | I-Polycarbonate | I-Acrylic | I-CR-39 | Ingilazi yomqhele | |
Inkomba ye-refractive | 1.60 | 1.59 | 1.60 | 1.50 | 1.52 |
Inombolo Abbe | 41 | 28-30 | 32 | 58 | 59 |
-Okukhethwa kukho kwamalensi okugqoka nsuku zonke nokushayela okuphephile
Cishe u-85% wabantu ubhekana nezinkinga zokubuka lapho ushayela, ikakhulukazi endaweni yokukhanya ebuthaka noma izimo zezulu ezimbi njengemvula, inkungu nenkungu, noma kuhwalala noma ebusuku.
1.Ukukhipha izinto ngokushesha lapho ushayela ngaphansi kwezimo zokukhanya okuphansi, njengezinsuku zemvula nezimnyama noma phakathi kwamabili noma ebusuku.
2.Ukuphazamiseka ngokuxhopha okuqhamuka ezimotweni ezizayo noma amalambu omgwaqo ebusuku.
3.Ukugxila kabusha phakathi komgwaqo nedeshibhodi kanye nezibuko ezisemaceleni/ezibonisa ngemuva.
Yahlulela amabanga kanye nezindawo zokushayela kalula nangokushesha ezinsukwini zemvula noma kuhwalala noma ebusuku.
Thola aukubona kahle komgwaqo, ideshibhodi, isibuko esikhombisa ngemuva kanye nezibuko ezisemaceleni.
Ungaphazanyiswa kancane ukukhanya okubenyezelayo ebusuku okuvela ezimotweni ezizayo noma amalambu omgwaqo.
Ilensi ephephile yokushayela imbozwe ngesembozo esikhethekile esithuthukisa ukugqama okubonakalayo futhi sinciphise ukubenyezela okukhishwa ezibanini ezicasulayo, ukukhanya kwelanga okuqinile noma ukukhanya okuvela endaweni ekhanyayo. Ngalo mbono ocacile futhi onethezekile, okumele ukwenze nje ukujabulela ukugibela.
Ukukhanya kwelanga kuhlala kuyinsiza enkulu kakhulu ekhipha ukukhanya okuluhlaza okwesibhakabhaka, ngisho nezinsuku eziguqubele. Ukukhanya okuluhlaza okulimazayo kuzodala Ukuxineka Kwamehlo, ikhanda elibuhlungu, inkinga yokulala, ukungaboni kahle. Ngamandla ayo aphezulu, ukukhanya okuluhlaza okwesibhakabhaka kungangena kwi-windshield yemoto futhi kufinyelele emotweni, okwenza i-eyeglass ibe yibhulokhi eluhlaza okwesibhakabhaka idingeke kakhulu.
I-drivesafe lens yethu ayisizi nje kuphela ukunciphisa ukukhanya, kodwa futhi ivimbela ukukhanya okuluhlaza okwesibhakabhaka. Ngakho-ke akuyona nje uhlobo lokushayela ilensi, kodwa futhi ukusetshenziswa usuku lonke.
Ilensi evimba ukukhanya okuluhlaza okwesibhakabhaka inezihlungi kumalensi awo avimba noma amunce ukukhanya okuluhlaza okwesibhakabhaka, futhi kwezinye izimo ukukhanya kwe-UV, ukuze kungangeni. Lokho kusho ukuthi uma usebenzisa lezi zibuko uma ubuka isikrini, zingasiza ekunciphiseni ukuchayeka kumagagasi okukhanya aluhlaza. Umbono wukuthi lokhu kusiza ukwephula ukugxila kwakho esikrinini sakho, kuvumela imisipha yamehlo akho ukuthi ikhululeke futhi kuvimbele ukucindezelwa kwamehlo.
