ʻO Resin kahi hydrocarbon (hydrocarbon) exudate mai nā ʻano mea kanu like ʻole, ʻoi aku ka conifers. Ma muli o kona ʻano kemika kūikawā a hiki ke hoʻohana ʻia e like me ka waiwai o kēia pena latex a me ka hoʻopili. He hui ia o nā pūhui molekala kiʻekiʻe, no laila, loaʻa nā wahi heheʻe ʻokoʻa. Hiki ke hoʻokaʻawale ʻia nā resins i nā resins maoli a me nā resins synthetic. Nui nā ʻano resin, hoʻohana nui ʻia i ka ʻoihana māmā a me ka ʻoihana kaumaha, i ke ola o kēlā me kēia lā hiki ke ʻike ʻia, e like me ka plastic, resin glasses, pena a pēlā aku. ʻO ka lens Resin ka lens ma hope o ka hoʻoili ʻana a me ka poli ʻana me ka resin ma ke ʻano he mea maka.

ʻO 1.56 ka hōʻailona refractive o ka lens
ʻOi aku ka kiʻekiʻe o ka helu refractive o ka lens, ʻoi aku ka lahilahi o ka lens o ke degere like. Hoʻohana ka hapa nui o ka poʻe i nā lens me kahi kuhikuhi refractive o 1.56. Inā kiʻekiʻe loa ke degere, ʻo nā lens me ka index refractive o 1.56 e mānoanoa loa, no laila pono mākou e koho i nā lens me kahi kuhikuhi refractive nui aʻe. ʻO ka uhi ʻana ka uhi ʻana i ka lens me kahi papa o nā mea i loaʻa nā hana like ʻole. kekahi
ʻO ke kiʻi anti-ultraviolet, hiki i kekahi ke pāʻani i ka hopena o ka hoʻonui ʻana i ka transmittance o ka lens, ʻoi aku ka maʻalahi o nā aniani.
ʻO ka mea maʻamau, i ke koho ʻana i nā lens, ʻōlelo ʻia ʻaʻole i kiʻekiʻe a haʻahaʻa paha ka helu refractive, no ka mea, ʻo nā lens me nā kuhikuhi refractive kūpono ʻole e hoʻonui i ke kaumaha o nā maka o nā maʻi. ʻO nā leki me ka 1.56 he haʻahaʻa refractive index, kūpono i nā poʻe maʻi me ka myopia haʻahaʻa a i ʻole myopia haʻahaʻa. Manaʻo ʻia ka poʻe me ka myopia haʻahaʻa a haʻahaʻa e koho i nā lens me ka index refractive ma waena o 1.50 a me 1.60.
Hoʻopili ʻia ka helu refractive i ka mānoanoa lahilahi o ka lens, akā i ke koho ʻana i ka lens, ʻaʻole pono ʻoe e nānā wale i ka refractive index, akā e hoʻohālikelike pū i ka gravity kikoʻī o ka lens, ka transmittance māmā, ka pale UV a me nā mea ʻē aʻe no ka noʻonoʻo piha.
