Kutheni kufuneka ukhethe iilensi zeCR-39 eziOptical?

Imitha ye-UV ekukhanyeni kwelanga inokuba yingozi emehlweni.
Iilensi ezivala i-100% ye-UVA kunye ne-UVB zinceda ekuthinteleni iziphumo ezinobungozi zemitha ye-UV.
Iilensi zefotochromic kunye nezona glasi zisemgangathweni zibonelela ngokhuseleko lwe-UV.

Kutheni kufuneka ukhethe iilensi zeCR-39 eziOptical?

ICrystal Vision (CR) ziilensi ezikumgangatho ophezulu ezenziwe yenye yeenkampani ezinkulu zehlabathi.
I-CR-39, okanye i-allyl diglycol carbonate (ADC), i-polymer yeplastiki esetyenziswa ngokuqhelekileyo ekwenzeni iilensi zeglasi.

Isishunqulelo simele "iColumbia Resin #39", eyayiyifomula yama-39 yeplastiki yokubeka thermosetting eyaphuhliswa yiprojekthi yeColumbia Resins ngo-1940.
Eyeye-PPG, le mathiriyeli iguqula ukwenziwa kweelensi.

Isiqingatha sobunzima njengeglasi, mancinci kakhulu amathuba okuba sibe nokuqhekeka, kwaye umgangatho wokukhanya uphantse ulingane neglasi.
I-CR-39 iyafudunyezwa kwaye igalelwe kwiimolds zeglasi ezisemgangathweni - ukulungelelanisa iimpawu zeglasi ngokusondeleyo kakhulu.
