Amathiphu okunciphisa izimpawu ezingathandeki
I-Astigmatism yinkinga ebonakalayo yombono, ethinta abantu abaningi okungenani ngezinga elithile. I-Astigmatism iyenzeka uma i- cornea noma i- lens yeso ine-curvature yangaphandle ehlukile kunezinye. Esikhundleni sokuba ngisho noma bushelelezi kuzo zonke izingqikithi, ubuso bungase bube buhle noma bukhulu ezindaweni ezithile. Izimali ezincane ze-astigmatism ngokuvamile aziphazamisi umbono futhi azidingi ukwelashwa.
Kodwa-ke, ezinye iziguli ezine-astigmatism zibonakala zinzima ukushayela ebusuku noma zisebenza ngaphansi kwezimo ezithile zokukhanya. Bavame ukukhalaza ngesithunzi esithinta izinhlamvu, ukuhlanekezela, ukukhanya kwe-glare kanye ne-halos ezungeze izibani. Uma uthola ukuthi une-astigmatism, amathiphu alandelayo angasiza ekuthuthukiseni izimpawu ezingadingeki:
Bheka Udokotela Wamehlo Ngokuvamile
Inani elincane noma eliningi le-astigmatism lingashintsha ngokuhamba kwesikhathi. Kubalulekile ukuthi imishanguzo yakho ivuselelwe ukuqinisekisa ukuthi yonke i-astigmatism yakho ilungiswa ngokugcwele.
Sebenzisa i-Anti-Reflective Coating
Buza ukuthi ukumboza okuphikisayo (noma ukulwa ne-anti-glare) kwengezwe ezibukweni zakho ezilandelayo. Ukugqoka okucatshangelwayo okunciphisa kunciphisa (kanti kwezinye izimo kuphelisa) ama-glare angafuneki, ama-halos nokuzindla okungaqondakali ukuthi ungathola ebusuku. Ngaphezu kwalokho, kuthuthukisa ukubukeka kwezimonyo zezibuko zakho. Linciphisa ukuzindla kwangaphakathi futhi uma une-astigmatism ephakeme kuyokwenza ukuthi ama-lens akho avele abe mncane futhi angabonakali.
Buza Mayelana namalensi okuxhumana
I-lens entsha ye-hybridi yakhela kangcono ekuthuthukiseni umbono kuziguli ezine-astigmatism. Ama-lens angama-hybrid akhiwa isikhungo esinzima esizungezwe isiketi esithambile. Lawa ma-lens ahlanganisa i-optics eqinile yensimbi eqinile ngenduduzo ye-lens elithambile.
Hlela Amehlo Akho
Uma ugqoka ama-lens okuthintana nama-astigmatism, faka amaconsi amaningi okuvuselela kabusha ngenkathi ugxila noma uhamba ushayela ebusuku.
Ukushisa ngeke kuthinte kuphela izinga le-optics lama-lens oxhumana nabo, kodwa amehlo akho angomile kakhulu ngokwanele ukuze enze ukujikeleza kwe-lens ngenkathi ekhanya. Ama-lens astigmatism axhumene nawo ayenzelwe ukuze ukushintshaniswa kuncishiswe.
