1）Ka Pono o nā Lens Bifocal

Koho kekahi mau presbyopes i nā lens multifocal holomua, e hoʻololi mālie i nā mana mai ka ʻaoʻao luna a i lalo o ka lens, me nā laina ʻole e hoʻokaʻawale iā lākou.Eia naʻe, hāʻawi nā bifocals maʻamau i kekahi pono ma mua o nā lens holomua, e like me ka hāʻawi ʻana i nā lens ākea no ka hana kamepiula a me ka heluhelu ʻana i hoʻohālikelike ʻia me nā lens holomua.Loaʻa ʻia nā bifocal kumu kūikawā no ka hana kamepiula a me nā hana ʻē aʻe e koi ana i ka ʻike maka kokoke a waena.
ʻOiai ke hana maikaʻi nei nā bifocals no nā hana e like me ka hoʻokele a me ka heluhelu ʻana, ua kaupalena ʻia ko lākou hiki ke hāʻawi i ka ʻike maopopo ma nā wahi ma waena, e like me ka mamao i kahi nānā kamepiula.
Ke hoʻohālikelike ʻia me nā lens holomua, ʻo ka maikaʻi o nā bifocals ʻo ia ka hilinaʻi a ʻoi aku ka liʻiliʻi ma mua o nā lens holomua.

2） Nā hiʻohiʻona o CR39 Lens:

① Ke hoʻohana nei i ka monomer CR39 me ka maikaʻi paʻa a me ka mana hana nui.i loaʻa pū i loko o ka home monomer CR39 lens production, nā huahana i hoʻokipa ʻia ma ʻAmelika Hema a me ʻAsia, hāʻawi pū i ka lawelawe HMC a me HC.
ʻOi aku ka maikaʻi o ka ②CR39 ma mua o ka Polycarbonate, ʻoi aku ka maikaʻi o ka ʻoni, a paʻa i ka ʻoni ma mua o nā mea lens ʻē aʻe.
③ ʻO kā mākou huahana CR39 he poepoe-luna, pālahalaha-luna, lens holomua, lens keʻokeʻo piha a me ka lenticular Lenticular.paʻa, lahilahi, māmā, kiʻekiʻe transmittance, paʻa kala, a me ka pololei hoʻolālā, hoʻolako pū i nā lens semi-hoʻopau.
④Me ke kumu kūʻai hoʻokūkū a me ka maikaʻi maikaʻi, ʻo Aogang optical e ʻimi mau ana i ka hui ʻoihana lōʻihi.
⑤He mau mea maikaʻi loa ia no nā makaaniani a me nā aniani kuhikuhi.
