Ezi glasi zidibanisa imisebenzi emininzi kunye neempawu zoyilo ukuze zikubonelele ngokukhululeka, okunesitayile, kunye namava aguquguqukayo.

Okokuqala, makhe sijonge kwiimpawu zokuyila iiglasi. Ngoyilo lwesakhelo esinesitayile, i-classical kwaye iguquguqukayo, nokuba inxibe ngokunxiba ngokungaqhelekanga okanye ngokusesikweni, inokubonisa ubuntu bakho kunye nencasa. Isakhelo senziwe nge-acetate, engeyona nje into ephakamileyo yokuthungwa, kodwa iphinde ibe yinto ehlala ihleli kwaye inokugcina inkangeleko entsha ixesha elide.

Ukongezelela, iiglasi nazo zixhotyiswe nge-lens zelanga zemagneti, ezilula kwaye zilula ukuthwala kwaye zinokufakwa ngokukhawuleza kwaye zisuswe, zibenze ziguquguquke kakhulu. Oku kuthetha ukuba unako ukufaka okanye ukususa iilensi zelanga kwiiglasi zokuqala nangaliphi na ixesha njengoko kufuneka, ngaphandle kokuthwala iiperesi ezininzi ezongezelelweyo zeeglasi, ezilungele kakhulu.

Ukongeza, sikwabonelela ngemibala eyahlukeneyo yeelensi zelanga zemagneti onokuthi ukhethe kuzo, nokuba ukhetha imibala yakudala enezitshixo ezisezantsi okanye imibala eqaqambileyo eqaqambileyo, uya kukufumana isitayile esifanelekileyo.

Ukongeza kwezi mpawu zingentla, sikwaxhasa uhlengahlengiso lwe-LOGO kunye nokupakishwa kweglasi ngokwezifiso, unokongeza i-LOGO yakho kwiiglasi ngokweemfuno zomntu okanye zeshishini, okanye wenze ngokwezifiso ukupakishwa kweeglasi ezikhethekileyo ukuze iiglasi zibe zezomntu ngakumbi.

Lilonke, ezi glasi zamehlo azinayo nje inkangeleko enesitayile kunye nemathiriyeli eyomeleleyo kodwa zinemisebenzi eyahlukeneyo yokusebenza ukuhlangabezana neemfuno zakho ezahlukeneyo kubomi bemihla ngemihla. Nokuba kukwimisebenzi yangaphandle okanye kwimisebenzi yemihla ngemihla, ezi glasi zimbini zinokuba ngumntu osekunene, zikuzisela amava okusebenzisa ngokukhululekileyo nafanelekileyo.
