ʻO Polycarbonate (PC), i ʻike ʻia ʻo PC plastic;He polymer ia i loko o ka hui carbonate i loko o ke kaulahao mole.Wahi a ke ʻano o ka pūʻulu ester, hiki ke hoʻokaʻawale ʻia i ka hui aliphatic, pūʻulu aromatic, pūʻulu aliphatic - pūʻulu aromatic a me nā ʻano ʻē aʻe.
ʻO ka lens PC i hana ʻia me ka diaphragm PC ʻo ia ka lens palekana loa i koi ʻia no nā haumāna kula haʻahaʻa a me ke kula kiʻekiʻe ma ʻEulopa a me ʻAmelika Hui Pū ʻIa, ʻo 70% o nā haumāna.

1, ʻaʻohe pilikia o loko
ʻO ke kikowaena o ka lens PC a hiki i ka lihi 2.5-5.0cm, ʻaʻohe hanana anuenue, ʻaʻole e hoʻonāwaliwali ka mea hoʻohana, pehu ka maka, luhi maka a me nā hopena ʻino ʻē aʻe.

2, ʻaʻahu-kū pale pua
ʻO ka ʻenehana paʻakikī hou o ka lens PC, i loaʻa i ka lens PC kahi hana anti-flower paʻakikī a paʻa, ikaika ka hopena hopena, hiki ke hoʻemi pono i ka hiki ke komo i ka lens, mālama lōʻihi i ka lens a maʻemaʻe.

3, anti-noʻonoʻo
PC lens vacuum coating, i hiki i ka transmittance o 99.8% a i ʻole, hiki ke hoʻopau pono i nā kuhikuhi āpau o ka noʻonoʻo ʻana, kūpono no ka hoʻokele pō, ʻoiai e hōʻemi ana i ka hoʻopuehu ʻana o ka mālamalama.

4, uhi paa
ʻO ka lens PC ma muli o ka hoʻohana ʻana i ka ʻenehana paʻakikī kūikawā, i mea e hōʻoia ai i ka paʻa ʻana o ke kiʻi ʻoniʻoni, ikaika overlaying ikaika, ʻaʻole maʻalahi e hāʻule.

5, lepo, wai a me ka noe
ʻO ka lepo, ka makū a me ka noe kekahi mau mea nui e pili ana i ka hoʻomaʻemaʻe ʻana o ka lens.Hoʻohana ka lens PC i ka ʻenehana paʻakikī kūikawā, kahi e hoʻomaikaʻi nui ai i ka hana lepo lepo, wai a me ka noe-proof o ka lens.

6, pale UV maoli
ʻAʻole i loaʻa i ka mea o ka resin sheet ka hana o ka pale UV, akā hilinaʻi i ka uhi ʻana ma luna o kona ʻili e pale ai i ka UV, a ʻo ka mea PC ponoʻī ka hana o ka pale UV, no laila, ʻo ka lens PC, inā he ʻāpana keʻokeʻo a i ʻole he kiʻiʻoniʻoni, he lōʻihi ka lōʻihi kaʻawale o UV 397mm ma lalo.

7，Ai-alohilohi
ʻO ka ili o ka lens PC he maʻalahi a palahalaha, i hoʻemi ʻia ka lūlū ʻana i loko o ka lens, i mea e hōʻemi ai i ka pōʻino o ka mālamalama i ka retina, a hoʻonui i ka ʻokoʻa kala o ka mea hoʻohana.

8, pono absorption o electromagnetic radiation hawewe
ʻO ke kaiapuni o nā hana kanaka ke kū nei me ka radiation electromagnetic, ʻoi aku ka hoʻohana pinepine ʻana i nā kamepiula.Hiki i nā lens PC ke komo pono i ka radiation i hoʻokomo ʻia e nā kamepiula.

9, māmā loa, lahilahi
Hana ʻia ka lens PC me nā mea māmā a me nā mea kiʻekiʻe, i hui pū ʻia me nā hopena o nā makahiki he nui o ka hoʻolālā optical a me ka noiʻi.Māmā nui, ʻoi aku ka lahilahi, hiki ke hoʻemi pono i ke kaomi o nā aniani ma ke alahaka o ka ihu.

10，Ai-impact
ʻO ka lens PC he 10 mau manawa ʻoi aku ka ikaika ma mua o ka hopena lens resin kuʻuna, 60 mau manawa ʻoi aku ka ikaika ma mua o ke aniani, ʻo ia ka lens kūpaʻa ʻoi loa i ka hopena o ka honua, ʻike ʻia kēia mea he aniani pōkā ma hope o ka mānoanoa.
