Kodi lens ingagwiritse ntchito chiyani, mwachitsanzo: kuteteza kuwala kwa buluu, kulamulira myopia, kuchepetsa kutopa ndi zina zotero, zonsezi ndi za ntchitoyo.
Ntchito zina za lens zimatha kuzindikirika ndi gawo la nembanemba, monga kuwala kwa buluu, anti-glare ndi zina zotero;
Zina zitha kupezedwa kudzera mu kapangidwe ka mandala, monga kukana kutopa kumapangidwira pang'onopang'ono, strabismus yolondola ndi prism yowonjezera, etc.;
Ena amafunikira kusintha mawonekedwe a gawo lapansi la lens kuti akwaniritse, monga kusintha kwa mtundu, utoto, kukana mphamvu, ndi zina.
Nthawi zambiri, mandala ogwira ntchito, mtengo ndi wokwera, ayenera kusankha A malinga ndi zomwe akufuna. Sankhani mbali yomwe mukufuna. Kuti mupewe kuwala kwa buluu, musayang'ane kusinthika. Kusankha magalasi molingana ndi ntchito yawo sikudzasokera.
Kuphatikiza apo, magwiridwe antchito amatha kukhala apamwamba, monga ma anti-blue color progressive lens, komanso ena.

Refractive index:
Ichi ndi chimodzi mwazinthu zodziwika bwino za lens, refractive index, mwa tanthawuzo, ndikutha kwa lens kupindika kuwala.
Pansi pazikhalidwe zomwezo, kuchuluka kwa refractive index, kumachepetsa mandala.
Chiwerengero cha refractive index ndi 1.50 (1.49, 1.51), 1.56 (1.55), 1.61 (1.60, 1.59), 1.67 (1.66), 1.71, 1.74 (1.73). Mlozera wa refractive wa zinthu zina m'makoloko udzapatuka pamtengo wokhazikika wa refractive index, womwe ulinso wagulu labwinobwino.
Zonsezi ndi refractive index of resin lens (palibe njira, onse ndi ma lens a utomoni tsopano), omwe amacheperako pang'ono m'tsogolomu, ndiye kuti, 1.67 refractive index lens ndiyoonda kuposa 1.56, ndipo 1.74 ndiyoonda kwambiri. ..
