ʻO nā lens maʻemaʻe ka mea maʻamau i hoʻohana ʻia no nā aniani hoʻoponopono.Ke hāʻawi nei i ka mālamalama kiʻekiʻe, hoʻemi i ka noʻonoʻo māmā, hoʻomaikaʻi i ka ʻokoʻa a me ka hoʻonui ʻana i ka hana ʻike, ʻo kā lākou hana ka hāʻawi ʻana i ka ʻike aniani me ka ʻoluʻolu.He kūpono nā lens maʻemaʻe no ka poʻe e hoʻohana i nā aniani i nā lā a pau.He mea maikaʻi nō hoʻi lākou no ka poʻe makemake i ka nānā ʻana i nā makaaniani e hāʻawi iā lākou, ʻoiai inā maikaʻi ko lākou mau maka.Ma kahi huaʻōlelo, maikaʻi nā lens māmā no kēlā me kēia
Hāʻawi ʻo Hopesun i kekahi o nā koho maikaʻi loa o nā lens maʻemaʻe i nā mea āpau mai ka 1.50 index a i 1.74 index.Hana ʻia nā lens a pau i nā mea maikaʻi maikaʻi loa o ka honua, e like me CR-39 mai PPG, MR series mai Mitsui Chemicals e hōʻoia i ka mālamalama o ka lens, palekana, paʻa.Hoʻopaʻa ʻo Hopesun i kahi ʻano nui a me ka nui o nā lens i hoʻopau ʻia i ka hihiʻo hoʻokahi, bifocal a me ka holomua.

Inā mahalo ʻoe i ka maikaʻi, ka hana a me ka hana hou ua hele mai ʻoe i kahi kūpono.

CR39(1.50 kuhikuhipuʻuone):Hōʻike ʻia ʻo CR39 e ka helu Abbe kiʻekiʻe, ke aniani kiʻekiʻe, ke kūpaʻa ʻaʻahu ikaika (me ka ʻole o ka uhi ʻana), ka haʻahaʻa haʻahaʻa (e pili ana i ka hapalua liʻiliʻi ma mua o ke aniani aniani), ka hana hoʻoluʻu maikaʻi, ka pale ʻana i ka solvent, ke kūʻē kemika a me ka pale wela.A no ka mea oo ke kaʻina hana, haʻahaʻa ke kumu kūʻai, a hiki i kēia manawa, ʻo ia kekahi o nā mea nui i ka ʻoihana lens.Eia nō naʻe, ʻoi aku ka liʻiliʻi o CR39 ma mua o nā mea ʻē aʻe e pili ana i ka hopena o ka hopena a me ka ikaika tensile, no laila, ʻaʻole kūpono ia no nā aniani rimless (ʻoi aku ka haki ʻana o nā lens i ka wā e wili ʻia ai), a loaʻa nō hoʻi iā ia ka ʻōlelo kuhikuhi refractive haʻahaʻa, e ʻoi aku ka mānoanoa o nā lens ma nā degere kiʻekiʻe.

1.56 Hōʻike hōʻike hoʻohālikelike:ʻO NK55 ka mea maka, ka mea i kapa pinepine ʻia he acrylic.He haʻahaʻa ke kumukūʻai a he kiʻekiʻe ka hoʻohana ʻana, akā nāwaliwali ka manaʻo māmā.He palupalu ka lens, a he maʻalahi ke haki i ka wā e wili ai i ke kiʻi.

1.59 mau mea PC:ʻO ka mea PC he Polycarbonate, he plastic thermoplastic me ka index refractive o 1.59 a me ke kūpaʻa ikaika.Hiki ke hoʻohana ʻia e like me nā aniani pōkā a me nā mahiole ma ke kahua kaua.Hiki ke hoʻohana ʻia i nā aniani me ka hopohopo ʻole i ka haki ʻana o nā lens.He kūpono ia no nā aniani rimless.A ʻoi aku ka kiʻekiʻe o ka index refractive ma mua o CR39, hiki ke hoʻonui ʻia ka lens.Akā ma ke ʻano he thermoplastic, ʻaʻole maikaʻi kāna hana ʻana a me ke kūpaʻa kemika, ʻaʻole i uhi ʻia ka ʻili i maʻalahi hoʻi e ʻoki, ʻaʻahu i ke kūpaʻa.Eia kekahi, ʻo kāna helu Abbe he 30, ʻo ia ka 28 ʻokoʻa mai CR39.

Mea MR (1.60MR-8, 1.67MR-7, 1.74MR-174):ʻO MR™ kahi pūʻulu o nā mea resin index refractive kiʻekiʻe a i hoʻomohala ʻia e Mitsui Chemical Company ma Iapana.Ma waho aʻe o MR174, hana ʻia ka moʻo holoʻokoʻa me ka polyurethane material (MR174 he mea sulfur ring me ka hoʻopuehu maikaʻi ʻana).ʻOiai ʻaʻole maikaʻi ka hopena o ka hopena e like me PC a me Trivex, loaʻa iā ia nā pōmaikaʻi ma mua o CR39.Eia kekahi, ʻoi aku ka maʻalahi o ka helu abbe o kēia moʻo o nā mea, ke kū ʻana i ka wela, ka pale ʻana i ka wā a me ke kūpaʻa kemika maikaʻi, no laila he hana piha maikaʻi.
