ilensi elungileyo, izinto zibalulekile
Izinto ezisetyenziswa kwiilensi zidlala indima ebalulekileyo ekudluliseleni kwazo, ukuqina kwazo kunye nenani le-Abbe (ipateni yomnyama kumphezulu welensi). Inokwenza uphando olunzulu kunye nophuhliso kwizinto, ngomgangatho olawulekayo kunye nokusebenza okugqwesileyo.
umaleko wefilimu, yenza ilensi ibe lula ukuyinxiba
Umaleko wefilimu yelensi olungileyo unokunika ilensi ukusebenza okugqwesileyo ngakumbi, kungekuphela nje ukusebenza kwe-optical okufana nokudluliselwa kwe-transmittance okuphuculwe kakhulu, ubulukhuni bayo, ukumelana nokuguguleka kwayo, kunye nokuqina kwayo kuya kuphuculwa kakhulu.

Iilensi ze-1.61 Blue Cut Spin Photochromic Gray HMC Optical
I-Resin yi-hydrocarbon (hydrocarbon) exudate evela kwizityalo, ngakumbi ii-conifers, ezixabisa ezinye izakhiwo zeekhemikhali ezikhethekileyo. I-Resin inokwahlulwa ibe ziintlobo ezimbini ze-resin yendalo kunye ne-resin yokwenziwa, kwaye ilensi ye-resin yilensi eyenziwe ngokwenziwa kweekhemikhali kunye nokupolisha nge-resin njengezinto eziluhlaza. Ilensi ye-resin ineenzuzo ezicacileyo, ubunzima bayo bulula, inxibe kakuhle ngakumbi; Okwesibini, ilensi ye-resin inokumelana okunamandla kwempembelelo kwaye ayibuthathaka kwaye ayikhuselekanga; Kwangaxeshanye, ilensi ye-resin ikwanokudluliselwa kokukhanya okuhle; Ukongeza, iilensi ze-resin kulula ukuziphinda zicutshungulwe ukuze zihlangabezane neemfuno ezizodwa. Okokugqibela, kunye nophuhliso kunye nokuphuculwa kwenkqubo yokugquma, iilensi ze-resin nazo zinokuxhathisa ukuguguleka okuhle, ngoko ke ziye zaba yeyona nto iphambili kwiilensi kwimarike.
