ʻO ka hoʻokaʻawaleʻana o nā mea nuiʻekolu
Nā aniani aniani
I nā lā mua, ʻo ka mea nui no nā lens he aniani optical.ʻO ka mea nui kēia no ka loaʻa ʻana o nā lens aniani optical i ka transmittance māmā, ka mālamalama maikaʻi, a me nā kaʻina hana maʻalahi a maʻalahi.Eia naʻe, ʻo ka pilikia nui loa me nā aniani aniani ko lākou palekana.ʻAʻole maikaʻi ko lākou hopena a maʻalahi loa e haki.Eia kekahi, kaumaha a ʻoluʻolu ʻole lākou e ʻaʻahu, no laila ua kaupalena ʻia kā lākou noi mākeke o kēia manawa.
Nā leki resin
ʻO nā lens Resin he mau lens optical i hana ʻia mai ka resin ma ke ʻano he mea maka, hana ʻia a synthesized ma o nā kaʻina kemika pololei a me ka polishing.I kēia manawa, ʻo ka mea i hoʻohana nui ʻia no nā lens he resin.ʻOi aku ka maʻalahi o nā lens Resin i ke kaumaha i hoʻohālikelike ʻia me nā aniani aniani a ʻoi aku ka ikaika o ka hopena ma mua o nā aniani aniani, ʻoi aku ka liʻiliʻi o ka haki ʻana a no laila palekana ke hoʻohana.Ma ke kumu kūʻai, ʻoi aku ka maʻalahi o nā lens resin.Eia nō naʻe, ʻoi aku ka maikaʻi o ka pale ʻana o nā lens resin, hiki ke hoʻoheheʻe ʻia, a ʻoi aku ka maʻalahi o ka ʻili o ka ʻili.
Nā leka PC
ʻO nā lens PC nā lens i hana ʻia mai ka polycarbonate (thermoplastic material) i hana ʻia e ka hoʻomehana ʻana.Ua hoʻokumu ʻia kēia mea mai ka noiʻi papahana lewa a ua ʻike ʻia hoʻi he lens space a i ʻole lens cosmic.No ka mea ʻo ka resin PC he mea thermoplastic kiʻekiʻe, kūpono ia no ka hana ʻana i nā lens maka aniani.Loaʻa i nā lens PC ka hopena maikaʻi loa, ʻaneʻane ʻaʻole nahā, a palekana loa ke hoʻohana.Ma ke ʻano o ke kaumaha, ʻoi aku ka māmā ma mua o nā lens resin.Eia nō naʻe, hiki ke paʻakikī i ka hana ʻana i nā lens PC, ʻoi aku ka nui o ke kumukūʻai.
Na Mea Kupono no ka Poe kahiko
No nā poʻe ʻelemakule e loaʻa ana i ka presbyopia, pono e koho i nā lens aniani a i ʻole nā lens resin.Pono ka Presbyopia i nā aniani heluhelu haʻahaʻa, no laila ʻaʻole hopohopo nui ke kaumaha o nā lens.Hoʻohui ʻia, ʻaʻole ʻeleʻele ka poʻe ʻelemakule, e hana ana i nā lens aniani a i ʻole nā lens resin paʻakikī ʻoi aku ka pale ʻana, ʻoiai e hōʻoiaʻiʻo ana i ka hana optical lōʻihi.
ʻO nā mea kūpono no nā mākua
He kūpono nā lens resin no nā ʻōpio waena a me nā ʻōpio.Hāʻawi nā lens Resin i kahi ākea o nā koho, me ka ʻokoʻa e pili ana i ka refractive index, functionality, a me nā kiko kikoʻī, no laila e hālāwai ai i nā pono like ʻole o nā hui like ʻole.
ʻO ka mea kūpono no nā keiki a me nā ʻōpio
Ke koho ʻana i nā aniani no nā keiki, ʻōlelo ʻia nā mākua e koho i nā lens i hana ʻia me nā mea PC a i ʻole Trivex.Ke hoʻohālikelike ʻia me nā ʻano lens ʻē aʻe, ʻaʻole maʻalahi wale kēia mau mea akā hāʻawi pū kekahi i ka pale hopena maikaʻi a me ka palekana kiʻekiʻe.Eia kekahi, hiki i nā lens PC a me Trivex ke pale i nā maka mai nā kukuna UV ʻino.
Paʻakikī loa kēia mau lens a ʻaʻole hiki ke haki, no laila ua kapa ʻia lākou he mau lens palekana.ʻO ke kaumaha wale nō 2 grams no ke kenimika cubic, ʻo ia ka mea māmā loa i hoʻohana ʻia no nā lens.ʻAʻole kūpono ka hoʻohana ʻana i nā aniani aniani no nā aniani o nā keiki, no ka mea, ʻeleʻele nā keiki a hiki i nā lens aniani ke haki, hiki ke hōʻeha i nā maka.
Ma ka Manao
ʻO nā hiʻohiʻona huahana o nā lens i hana ʻia mai nā mea like ʻole he ʻokoʻa loa.He kaumaha a he haʻahaʻa haʻahaʻa ko nā aniani aniani, akā he ʻuʻuku lākou a lōʻihi ka hoʻohana ʻana, e kūpono ai i nā poʻe ʻelemakule me nā haʻahaʻa haʻahaʻa o ke kino a me ka presbyopia haʻahaʻa.Hele mai nā lens Resin i nā ʻano like ʻole a hāʻawi i ka hana piha, e kūpono ana ia no nā ʻano noiʻi like ʻole a me nā pono hana o ka poʻe waena a me nā ʻōpio.I ka hiki ʻana i nā maka aniani o nā keiki, koi ʻia ka palekana kiʻekiʻe a me ka māmā, ʻoi aku ka maikaʻi o nā lens PC.
ʻAʻohe mea maikaʻi loa, ʻo ka ʻike loli ʻole o ke olakino maka.Ke koho ʻana i nā lens i hana ʻia i nā mea like ʻole, pono mākou e noʻonoʻo mai ka manaʻo o ka mea kūʻai aku, me ka hoʻomanaʻo ʻana i nā loina ʻekolu o ka pono aniani: ʻoluʻolu, lōʻihi, a me ke kūpaʻa.
