1.59 PC Bifocal Invisible Photochromic Grey HMC Optical lens Kiʻi ʻia

ʻO ka wehewehe pōkole:

I kēia manawa, ʻelua ʻano mea lens ma ka mākeke, hoʻokahi mea aniani, ʻo kekahi mea resin. Hoʻokaʻawale ʻia nā mea resin i CR-39 a me polycarbonate (mea PC).

ʻO nā lens bifocal a i ʻole nā lens bifocal nā lens i loaʻa ʻelua mau wahi hoʻoponopono i ka manawa like a hoʻohana nui ʻia e hoʻoponopono i ka presbyopia. ʻO ka ʻāpana mamao i hoʻoponopono ʻia e ka lens bifocal ua kapa ʻia ka ʻāpana mamao, a ʻo ka wahi kokoke i kapa ʻia ʻo ka wahi kokoke a me ka wahi heluhelu. ʻO ka mea maʻamau, nui ka ʻāina mamao, no laila ua kapa ʻia ʻo ia ke kiʻi nui, a liʻiliʻi ka ʻāina proximal, no laila ua kapa ʻia ʻo ia ka sub-film.

He aha nā hiʻohiʻona o nā aniani aniani? ʻO ka paʻakikī kiʻekiʻe, ʻaʻohe paʻakikī, maʻalahi ke haki i ka wā e paʻi ai. He kiʻekiʻe ka transparency a me ka māmā transmittance o 92 pakeneka. Paʻa kemika a me ke kino, hiki ke pale i ka mana o nā ʻano ʻano like ʻole, ʻaʻole kala, ʻaʻole e mae. Ma muli o kona kaumaha kaumaha, ʻaʻole kūpono ia no nā ʻōpio.

He aha nā pōmaikaʻi o ka lens resin? Hana ʻia nā lens resin me diethylene glycol a me propylene glycol lipid reaction polymerization. ʻO ke kaumaha māmā, ke kūpaʻa hopena maikaʻi, ke kūpaʻa wela kiʻekiʻe, ka transmittance māmā maikaʻi, kokoke i ka hana o nā aniani aniani, hiki ke pale i nā kukui ultraviolet.

He aha nā pōmaikaʻi o nā lens PC? ʻO ka lens PC i ʻike ʻia ʻo: kahi ʻāpana a i ʻole ʻāpana ākea, i hana ʻia me nā mea PC mākaʻikaʻi ma o ka hana ʻana i ka hoʻoheheʻe ʻana. Loaʻa iā ia ka paona māmā, ka ikaika hopena kiʻekiʻe, ke kūpaʻa maikaʻi o ka wā, ka transmittance māmā maikaʻi, 100% ultraviolet absorption, non-toxic, a me ka palekana o ke kaiapuni, me kahi ākea o nā manaʻo hoʻomohala.

Hoʻohana ʻia ka hapa nui o nā bifocals e hoʻololi i ʻelua mau bifocals i hoʻohana ʻia e ʻike i kahi mamao a ʻike kokoke, no laila, ʻo ke kūlana a me ka nui o ka wahi nānā mamao a me nā wahi nānā kokoke e kūpono i nā maka aniani ʻelua. Inā ʻoi aku ka mana o ka ʻike kokoke, hiki i nā subslices ke ʻoi aku ka nui a me ke kūlana kiʻekiʻe; Ma ka ʻaoʻao ʻē aʻe, inā ʻoi aku ka nui o ka manawa i ka nānā ʻana i kahi mamao, ʻoi aku ka liʻiliʻi o nā sub-slices a haʻahaʻa i ke kūlana. ʻAʻohe ʻano hoʻolālā e hiki ke hoʻokō i nā pono o nā kūlana like ʻole. Pono e koho ʻia a hoʻohālikelike ʻia e like me nā pono ʻike maoli o nā mea hoʻohana, a i kekahi manawa pono e hoʻohana ʻia nā hoʻolālā like ʻole e hoʻokō i nā pono ʻike o nā kūlana like ʻole me nā ʻokoʻa nui.
