Ma ke ʻano o ka hana hou optical, ua hoʻokaʻawale ʻia ka hoʻolālā lens i ʻelua ʻano: spherical a me aspheric.ʻO nā lens Aspheric, i alakaʻi ʻia e ka ʻimi ʻana i ka slimness, pono e hoʻololi i ka curvature lens, e hoʻokaʻawale loa mai ka curvature spherical lens maʻamau.ʻO ka hoʻolālā spherical, kahi maʻamau ma mua, ua hoʻopilikia ʻia e ka hoʻonui ʻana i nā aberrations a me nā distortions.ʻO kēia ka hopena pinepine i nā pilikia i haʻi ʻia e like me nā kiʻi polū, ʻike maka, a me kahi kahua o ka ʻike.
I kēia manawa, ua puka mai ka hoʻolālā aspheric ma ke ʻano he ikaika hoʻoponopono, e hoʻoponopono pono i kēia mau hiʻohiʻona hiʻohiʻona a hāʻawi i kahi hopena e hāʻawi ai i nā lens ʻaʻole ʻoi aku ka māmā a me ka lahilahi akā ua palahalaha hoʻi.ʻO ka mea nui, ʻaʻole e hoʻohālikelike kēia mau holomua i ka hopena koʻikoʻi o ka lens, e hōʻoiaʻiʻo ana i kahi ʻike palekana.
Loaʻa ka ʻaoʻao haʻahaʻa o nā lens spherical kuʻuna - ʻike ʻia nā mea i nānā ʻia a puni ka ʻaoʻao o ka lens, e hoʻopaʻa ʻia ana ka ʻike o ka mea hoʻohana.I kahi makahiki e ulu mau ai ka ʻenehana, nā lens aspheric - he mea kupanaha maoli - e hōʻemi i nā aberrations ma ka ʻaoʻao o ka lens, e hoʻonui nui i ke kahua o ka ʻike e hoʻokō i nā koi o ka mea kūʻai aku.Hōʻike ʻia nā lens Aspheric i kahi kāwele kumu pālahalaha a ʻoi aku ka māmā, e hoʻonui ana i ka hoʻopiʻi kūlohelohe a me ka nani.ʻOi loa i nā hihia o ka mana refractive kiʻekiʻe, hoʻemi maikaʻi lākou i ka distortion o ka maka, e hoʻolilo iā lākou i koho maikaʻi loa no nā mea kūʻai aku me nā koi ʻoi aku ka nui.
ʻO ka hiʻohiʻona wehewehe o nā lens aspheric ko lākou curvature ili kūikawā.Hāʻawi kēia hoʻolālā aspheric i nā pono he nui ma mua o nā lens spherical kuʻuna:
1.Clarity: Hana ʻia me kahi kaʻina hana uhi kūikawā, hāʻawi nā lens aspheric i nā hiʻohiʻona hiʻohiʻona hiʻohiʻona, e hōʻoiaʻiʻo ana i kahi ʻike ʻike a ʻoluʻolu.
2. Hōʻoluʻolu: No laila ka māmā ua aneane hiki ʻole ke ʻike ʻia, nā lens aspheric e hoʻemi i ka 'kaumaha' i kou mau maka, e ʻae ai i kahi lole hoʻomaha a me ka hana ʻole.
3.Natural Vision: ʻO kā lākou hoʻolālā aspheric e hoʻemi i ka distortion hiʻohiʻona, e alakaʻi ana i kahi ʻike maoli a pololei.
ʻO ka hoʻohālikelike ʻana i nā lens spherical a me aspheric o nā mea like a me ka ʻōlelo kuhikuhi, ʻoi aku ka maikaʻi o nā lens aspheric ma ke ʻano he palahalaha, ʻoi aku ka lahilahi, a hāʻawi i nā ʻike ʻike maoli a ʻoluʻolu.ʻO ka nānā ʻana i ke ʻano o ka uhi ʻana o kahi lens i kahi kumu māmā e hōʻike ana i ka ʻoi aku o ka pololei o ka noʻonoʻo ʻana mai nā lens spherical (koe naʻe nā lens mana refractive kiʻekiʻe);ʻO nā lens aspheric, akā naʻe, hōʻike i ka curvature nui aʻe ma muli o nā ʻano curvatures ma luna o ko lākou ʻili.
ʻAʻole ʻoi aku ka mānoanoa o nā ʻaoʻao ʻaoʻao o nā lens spherical kuʻuna akā hoʻololi a wili i ka ʻike o nā mea, kahi ʻano i kapa ʻia ʻo ke kiʻi aberration.No ka hoʻokō ʻana i kahi hoʻolālā māmā, ua hoʻohana ʻia nā mea kiʻekiʻe refractive index i ka hana ʻana i nā lens.Eia kekahi, ke nānā ʻia ma o nā lens spherical, ʻike ʻia ke ʻano o ka helehelena o ka mea hoʻohana.ʻO nā lens Aspheric, ʻokoʻa, e hōʻemi i ke kikowaena a me ka mānoanoa o ka ʻaoʻao, e hopena i kahi lens slimmer e hoʻopau i nā aberrations peripheral, no laila e hāʻawi ana i kahi ʻike ʻike kūlohelohe.
Hāʻawi nā lens Aspheric i kahi ākea ākea a ʻike ʻole ʻia ma nā ʻaoʻao, me ka liʻiliʻi o ke kiʻi aberration, e hoʻolilo i nā kiʻi i mea kūlohelohe maoli.ʻO kēia mau lens he ʻekolu manawa ʻoi aku ka paʻakikī ma mua o ko lākou mau hoa spherical, no laila kūpono lākou i nā mea ʻōpio.Me ka like -5.00DS prescription, ʻoi aku ka māmā o nā lens aspheric 26% ma mua o nā lens spherical.ʻO ko lākou ʻili palahalaha e hōʻoiaʻiʻo i ka ʻike kūlohelohe, ʻike ʻole ʻia o ka honua, kokoke a mamao, e hōʻemi ana i ka luhi o ka maka i nā manawa lōʻihi.
He kūpono no nā mea hoʻohana maka aniani mua, ʻoi aku ka nui o nā haumāna a me nā limahana o ke keʻena, nā lens aspheric e hōʻoluʻolu nui i ka ʻeha mua e pili ana i ke komo ʻana i nā aniani.He mea koho maikaʻi loa ia no nā mea hoʻohana lens contact, e lawelawe ana ma ke ʻano he pale maka ma ka home.Hoʻohālikelike nā lens Aspheric i ka ʻike kūlohelohe, e like me ka ʻike me nā lens pili.He kūpono lākou no ka poʻe makemake e hoʻohaʻahaʻa i kā lākou ʻōlelo kuhikuhi kiʻekiʻe, makemake e pale i ke ʻano o nā maka liʻiliʻi me nā aniani myopia, e ʻimi e hoʻomāmā i ke kaumaha o kā lākou mau lens, a i ʻole nā pono refractive o kēlā me kēia maka.
Hiki i nā lens Aspheric ke hāʻawi i nā lens refractive index medium i ka hiʻohiʻona liʻiliʻi a me ka palahalaha e like me nā lens refractive index kiʻekiʻe, e hōʻemi ana i nā aberrations lihi a mālama i kahi ākea ākea e hoʻokō i nā pono āpau.
