Iilensi zeglasi zelanga ezenziwe kwinayiloni, iCR39 kunye nemathiriyeli yePC zineenzuzo zazo kunye nezingeloncedo zazo.Inayiloni yipolymer eyenziweyo ekhaphukhaphu, ihlala ixesha elide kwaye ibhetyebhetye.Inokumelana okuphezulu kwimpembelelo kwaye inokumelana namaqondo okushisa aphezulu.Iilensi zenayiloni zilula ukuvelisa ngokusebenzisa inkqubo yokubumba kwaye zifumaneka ngokubanzi kuluhlu lwemibala kunye neetinti.
I-CR39 luhlobo lweplastiki eyaziwa ngokucaca kwayo kunye nokumelana nokukrala.Ezi lens zikhaphukhaphu, zomelele kwaye azibizi kakhulu xa zithelekiswa nezinye izinto.Zenziwa ngokusebenzisa inkqubo yokuphosa evumela ukuba umgangatho ophezulu wokuchaneka kunye nokulawula umgangatho.Iilensi zeCR39 zikwalula ukwenza i-tint kwaye ziyafumaneka kuluhlu lwemibala kunye nemibala.
I-PC (i-polycarbonate) luhlobo lwe-thermoplastic eyaziwa ngokuxhathisa impembelelo kunye nokuqina.Ezi lens zikhaphukhaphu kwaye zisoloko zisetyenziswa kwiindondo zezemidlalo nezokhuseleko.Zenziwa ngokusebenzisa inkqubo yokubumba i-injection evumela ukuba umgangatho ophezulu wokuchaneka kunye nokuhambelana.Iilensi zePC zikwafumaneka kuluhlu lwemibala kunye neetinti, kodwa azikwazi ukumelana nomkrwelo njengeelensi zeCR39.
Ngokubhekiselele kwiinzuzo zabo, iilensi zenayiloni ziguquguqukayo, zihlala zihlala kwaye zixhathisa impembelelo.Iilensi zeCR39 zicacile kwaye azikwazi kukrweleka.Iilensi zePC azinampembelelo kwaye ziqinile.
Nangona kunjalo, kukwakho nezinye izinto ezingeloncedo ekufuneka ziqwalaselwe.Iilensi zenayiloni zinokuthambekela ngakumbi ekubeni tyheli kwaye zibe nombala ngokuhamba kwexesha.Iilensi zeCR39 zinokumelana nempembelelo encinci xa kuthelekiswa nezinye izinto.Iilensi zePC zisenokungacaci njengee-CR39 lens kwaye zithande ukukrwela.
Ukuqukumbela, ukukhethwa kwezinto eziphathekayo kwiilensi zelanga kuya kuxhomekeka kusetyenziso olucetywayo kunye nokukhethwa komntu.Iilensi zenayiloni zifanelekile kwabo bafuna ukuguquguquka kunye nokuqina, iilensi zeCR39 zifanelekile kwabo babeka phambili ukucaca kunye nokumelana nokukrweleka, kwaye iilensi zePC zilungele abo bafuna ukuchasana nokuqina kunye nokuqina.
