1.56 Nā Lens Optical Semi-Finished Single Vision

ʻO ka wehewehe pōkole:

Hoʻohana ʻia nā lens o nā aniani semi-finished e kali no ka hana ʻana. Hele mai nā ʻāpana like ʻole me nā lens like ʻole, pono e hoʻomaʻamaʻa ʻia a hoʻoponopono ʻia ma mua o ke komo ʻana i ke kiʻi.

ʻO ka mea lens

1. Nā leka uila. Hoʻokaʻawale ʻia nā lens plastik i ʻekolu ʻano: nā lens resin, nā lens PC, nā lens acrylic. Loaʻa iā ia nā pōmaikaʻi o ka māmā a me ka hiki ʻole ke haki. Ke hoʻohālikelike ʻia me nā aniani aniani, ʻoi aku ka maikaʻi o ka hana anti-ultraviolet. Akā ʻilihune ka hana ʻana o ka lens plastic, makaʻu i ka hopena, i ka wā e hoʻihoʻi hou ai, pono e hoʻolohe.

2. Maka aniani. Paʻa ka hana optical o ka lens aniani, ʻaʻole maʻalahi ke deform, akā he palupalu, ʻaʻole lawa ka hana palekana, i kēia hihia, ʻoi aku ka kiʻekiʻe o ka hana palekana o ka lens aniani i hoʻomohala ʻia.
3. Polarizing lens. ʻO ka lens polarized ka mea nui i hana ʻia me ka hoʻohana ʻana i ke kumu polarization o ka māmā. Hiki iā ia ke hoʻomaʻamaʻa i ka ʻike a ʻoki i ka ʻālohilohi ma waho o ka lens. He lens ia i hoʻohana nui ʻia ma ka mākeke i kēia lā.

4. Nā leka hoʻololi kala. ʻO nā lens hoʻololi kala nā lens e hana i nā kala like ʻole ma muli o ke ʻano o ka hoʻololi ʻana o ka mālamalama. Hāʻawi ia i nā maka e hoʻololi i nā ʻano māmā like ʻole, a ʻo nā aniani me nā lens hoʻololi kala e ʻike pū ʻia ʻo ia ka mea kūpono loa no ka myopia.

ʻO ka ʻōlelo kuhikuhi refractive e pili ana i ka helu refractive o ka lens, a ʻoi aku ka kiʻekiʻe o ka refractive index, ʻoi aku ka lahilahi o ka lens. ʻO ka helu helu refractive maʻamau he 1.49, 1.56, 1.61, 1.67, 1.74.

Pono e noʻonoʻo piha ʻia ka helu kuhikuhi refractive kūpono e like me ke degere, ka mamao o ka haumāna a me ka nui o ke kiʻi. Ma keʻano laulā, ʻoi aku ka kiʻekiʻe o ke degere, ʻoi aku ka kiʻekiʻe o ka ʻōlelo kuhikuhi refractive o ka lens, e ʻike ʻia ka lahilahi. Pēlā nō, inā liʻiliʻi ka lōʻihi o ka haumāna a nui ke kiʻi, pono ʻoe e koho i kahi aniani kuhikuhi refractive kiʻekiʻe e ʻoi aku ka lahilahi o ka lens. Ma ka ʻaoʻao ʻē aʻe, inā liʻiliʻi ke kiʻi a nui ka mamao o ka haumāna, ʻaʻohe pono e alualu i kahi lens kiʻekiʻe.
