1. He aha ka lens PC?
ʻO ka PC kahi hana maikaʻi o nā plastics ʻenekinia thermoplastic, ʻelima ʻenehana ʻenekinia i loko o ka ʻike maikaʻi o ka huahana, akā i nā makahiki i hala iho nei ka ulu wikiwiki ʻana o nā plastic engineering maʻamau.I kēia manawa, hoʻohana nui ʻia ia i ka optics, electronics, architecture, automobile, healthcare and other fields, especially for the production of eyeglasses.

2. No ke aha i kapa ʻia ai lākou he lens lewa?
ʻO POLYCARBONATE (PC) kahi mea i hoʻomohala ʻia e nā ʻepekema e hana i nā lako ʻimi ākea kūpono no ke kaiapuni kūikawā o ka lewa, no laila ua kapa ʻia ʻo ia he lens lewa.

3. He aha ka maikaʻi o ia mea?
Loaʻa i nā mea PC nā mea maikaʻi o ka ultra-thin, ultra-light, high collision resistance, UV protection and good light transmittance, hoʻohana nui ʻia i ka ʻenekinia plastics transparent material, He kūpaʻa maikaʻi a ʻaʻohe conductivity uila, no laila ākea loa ka laulā noi, a hana ʻia me nā pono o luna, kūpono i ka helu kiʻekiʻe, e hoʻolohe i ka poʻe nani, nā mea haʻuki, nā keiki, nā keiki, nā keiki, nā makahiki 1 e ʻaʻahu ʻia e nā keiki o ʻAmelika Hui Pū ʻIa. Nā leka PC.
ʻO nā lens resin maʻamau he mau mea paʻa wela, ʻo ia hoʻi, he wai ka mea maka, wela e hana i nā lens paʻa.ʻO ka ʻāpana PC he mea thermoplastic, ʻo ia hoʻi, paʻa ka mea maka, ma hope o ka hoʻomehana ʻana, hoʻohālikelike ʻia no ka lens, no laila e hoʻopau ʻia kēia huahana lens, ʻaʻole kūpono no ka haʻahaʻa kiʻekiʻe a me nā manawa wela.He paʻakikī ikaika ka lens PC, ʻaʻole i haki (hiki ke hoʻohana ʻia ka 2cm no ke aniani pale), no laila ua kapa ʻia ʻo ia he lens palekana.ʻO ka umekaumaha kikoʻī he 2 grams wale nō kēlā me ke kenimika cubic, e lilo ia i mea māmā loa i hoʻohana ʻia i kēia manawa no nā lens.ʻO ka mea hana lens PC ka mea alakaʻi honua ʻo Esilu, ʻike ʻia kāna mau mea maikaʻi i ka mālama aspheric lens a me ka mālama paʻakikī.
Hana ʻia nā lens space PC me nā lens polycarbonate, a he ʻokoʻa koʻikoʻi nā lens resin maʻamau (CR-39)!ʻIke pinepine ʻia ʻo PC ma ke aniani bulletproof, no laila nā lens PC e pili ana i nā hiʻohiʻona maikaʻi loa o nā mea maka i ka hopena super impact resistance, a ma muli o ke kiʻekiʻe refractive index a me ke kaumaha māmā, hoʻemi nui i ke kaumaha o ka lens, ʻoi aku ka maikaʻi e like me: 100% UV pale, 3-5 mau makahiki ʻaʻole e melemele.Inā ʻaʻohe pilikia i ke kaʻina hana, ʻoi aku ka māmā o ke kaumaha ma mua o ka pepa resin maʻamau, a ʻo ka hopena o ka hopena a hiki i 12 mau manawa o ka resin maʻamau!

4. Ka mōʻaukala o nā lens PC
I ka makahiki 1957,
Ua alakaʻi ka hui ʻAmelika GE (General Electric) i ka hoʻomohala ʻana i ka plastic PC(polycarbonate), a kapa ʻia ʻo Lexan.Ua hahai ka hui Kelemania ʻo Bayer me kā lākou PC plastic Makrolen.
I ka makahiki 1960
Ua pau ke kenekulia ʻelua.Ua hoʻololi ʻo PPG i ka mea resin CR-39 mai ka pūʻali koa e hana i nā lens no ka hoʻohana kīwila.
I ka makahiki 1970
I ka hoʻomaka ʻana o nā makahiki 1970, hoʻomaka nā mea maʻi e loaʻa nā lens CR-39.
I ka makahiki 1973,
85% mau aniani aniani a me 15% CR-39.
I ka makahiki 1978,
Me ka pono o ka pūʻali koa a me nā papahana aerospace, ua hoʻohana mua ʻo Gentex i ka PC e hana i nā lens palekana.
I ka makahiki 1979,
I nā ʻāina i kūkulu ʻia, hoʻololi ʻia ka mea lens mai ke aniani i ka resin CR-39.E hoʻopau ana i ka noho aliʻi ʻana o 600 makahiki o ka lens aniani.
I ka makahiki 1985,
Ua hoʻolauna ʻo Vision-ease Lenses Inc. i ka hoʻokomo ʻana i nā lens prescription PC.
I ka makahiki 1991,
Hoʻokuʻu ʻo Transitions, Inc. i ka hanauna mua o nā lens resin hoʻololi kala.
I ka makahiki 1994,
ʻO nā lens PC he 10% o ka mākeke US.
I ka makahiki 1995,
Ua hānau ʻia ka lens PC polarizing.
I ka makahiki 2002,
Loaʻa nā lens PC no 35% o ka mākeke US, aʻo nā lens aniani ma lalo o 3%
