ʻO kahi hōʻuluʻulu pōkole o ka uhi ʻana o nā aniani maka

Ua kamaʻāina nā lens i nā poʻe he nui, a he hana nui lākou i ka hoʻoponopono ʻana i ka myopia ma nā aniani.Loaʻa i nā lens nā ʻāpana ʻokoʻa, e like me ka uhi ʻōmaʻomaʻo, ka uhi uliuli, ka uhi ʻulaʻula-ʻulaʻula, a me ka uhi gula nani.ʻO ka ʻaʻahu a me ka waimaka o nā papa uhi kekahi o nā kumu nui o ka hoʻololi ʻana i nā maka aniani, no laila e aʻo hou aʻe e pili ana i nā papa uhi o nā lens.

ʻO ka hoʻomohala ʻana o ka uhi ʻana o ka lens
Ma mua o ka hiki ʻana mai o nā lens resin, hoʻohana mau ʻia nā aniani aniani.ʻO nā mea maikaʻi o nā lens aniani he kiʻekiʻe refractive index, high light transmittance, a me ka paʻakikī kiʻekiʻe, akā loaʻa iā lākou nā hemahema e like me ka hiki ke haki, kaumaha, a palekana.

No ka hoʻoponopono ʻana i nā hemahema o nā aniani aniani, ua hoʻomohala nā hale hana i nā mea like ʻole e pani i nā aniani aniani, akā ʻaʻohe mea kūpono.Loaʻa i kēlā me kēia mea i kona pono ponoʻī a me nā hemahema, a he paʻakikī ke hoʻokō i kahi kaulike.Pili kēia i nā lens resin o kēia manawa (nā mea resin).
No nā lens resin o kēia manawa, pono ka uhi ʻana.Loaʻa i nā mea Resin nā papa helu he nui, e like me MR-7, MR-8, CR-39, PC, NK-55-C, a me nā mea resin he nui, kēlā me kēia me nā ʻano like ʻole.ʻOiai he lens aniani a he lens resin paha, e hele ana ka mālamalama e hele ana ma ka ʻili o ka lens e loaʻa i nā ʻano hiʻohiʻona like ʻole: ka noʻonoʻo ʻana, ka refraction, absorption, scattering, a me ka lawe ʻana.

E uhi i ka lens me kahi kiʻi anti-reflective
Ma mua o ka hiki ʻana o ka mālamalama i ka ʻili o ka lens, he 100% ka ikehu māmā, akā i ka puka ʻana o ka lens a komo i ka maka, ʻaʻole ia he 100% ka ikehu māmā.ʻOi aku ka kiʻekiʻe o ka pākēneka o ka ikehu māmā, ʻoi aku ka maikaʻi o ka lawe ʻana i ka māmā, a ʻoi aku ka kiʻekiʻe o ka maikaʻi a me ka hoʻonā kiʻi.
No kahi mea lens kiko'ī, ʻo ka hōʻemi ʻana i ka nalowale o ka noʻonoʻo ʻana he ala maʻamau e hoʻonui ai i ka lawe māmā.ʻOi aku ka nui o ka mālamalama, ʻoi aku ka haʻahaʻa o ka transmittance o ka lens, ka hopena i ka maikaʻi ʻole o ke kiʻi.No laila, ua lilo ka hoʻohaʻahaʻa ʻana i ka noʻonoʻo ʻana i pilikia e pono e hoʻonā nā lens resin, a ua hoʻopili ʻia ke kiʻi anti-reflective (AR film) i ka lens (i ka mua, ua hoʻohana ʻia nā uhi anti-reflective ma kekahi mau lens optical).
Hoʻohana ke kiʻi ʻoniʻoni anti-reflective i ka loina interference e loaʻa ai ka pilina ma waena o ka nānā ʻana i ka ikaika o ka māmā o ka lens i uhi ʻia i ka papa kiʻi anti-reflective a me ka lōʻihi o ka hawewe o ka mālamalama hanana, ka mānoanoa o ka papa kiʻiʻoniʻoni, ka kuhikuhina refractive o ka papa kiʻiʻoniʻoni, a ʻO ka helu helu refractive o ka substrate lens, e ʻae ana i ke kukui e hele ana i ka papa kiʻiʻoniʻoni e hoʻopau i kekahi i kekahi, e hōʻemi ana i ka nalowale o ka ikehu māmā ma ka ʻili o ka lens a hoʻomaikaʻi i ka maikaʻi a me ka hoʻonā kiʻi.
Hoʻohana pinepine ʻia nā mea hoʻoheheʻe anti-reflective i nā oxide metala maʻemaʻe kiʻekiʻe e like me ka titanium dioxide a me ka cobalt oxide, i waiho ʻia ma ka ʻili o ka lens ma o ke kaʻina evaporation (vacuum deposition) e loaʻa ai nā hopena anti-reflective maikaʻi.Haʻalele pinepine nā ʻāpana anti-reflective i nā koena, a ʻo ka hapa nui o nā ʻāpana kiʻiʻoniʻoni i ka nui o ke kala ʻōmaʻomaʻo.

Hiki ke hoʻomaluʻia ke kala o ke kiʻi anti-reflective, no ka laʻana, e hana i nā kiʻi polū, kiʻi blue-violet, kiʻi violet, kiʻi hina, a pēlā aku.Loaʻa nā ʻokoʻa o nā papa kiʻiʻoniʻoni kala like ʻole i ka hana hana.ʻO kahi laʻana, ʻo ke kiʻi ʻoniʻoni polū ʻo ia ka mea e pono ke hoʻomalu ʻia ka nānā ʻana haʻahaʻa, a ʻoi aku ka paʻakikī o ka uhi ʻana ma mua o ke kiʻi ʻōmaʻomaʻo.Eia naʻe, hiki ke emi ma lalo o 1% ka ʻokoʻa o ka hoʻouna māmā ʻana ma waena o nā kiʻiʻoniʻoni uliuli a me ka ʻōmaʻomaʻo.
I nā huahana lens, ʻoi aku ka maʻamau o nā kiʻiʻoniʻoni polū ma waena o nā lens kiʻekiʻe.Ma ke kumu, ʻoi aku ka kiʻekiʻe o ka lawe māmā ʻana o nā kiʻiʻoniʻoni polū ma mua o nā kiʻi ʻoniʻoni ʻōmaʻomaʻo (e hoʻomanaʻo ʻo ia ke kumu) no ka mea, ʻo ka māmā he hui pū ʻana o nā nalu ʻokoʻa, a ʻokoʻa nā kūlana kiʻi ʻokoʻa o nā nalu ʻokoʻa ma ka retina.Ma lalo o nā kūlana maʻamau, kiʻi pololei ʻia ke kukui melemele-'ōmaʻomaʻo ma ka retina, a ʻoi aku ka kiʻekiʻe o ka ʻike ʻike i hāʻawi ʻia e ke kukui ʻōmaʻomaʻo, no laila ua maʻalahi ka maka o ke kanaka i ke kukui ʻōmaʻomaʻo.

E uhi i ka lens me kahi kiʻiʻoniʻoni paʻa
Ma waho aʻe o ka hoʻouna ʻana i ka māmā, ʻoi aku ka nui o ka resin a me nā mea aniani: ʻaʻole paʻakikī nā lens.
ʻO ka hoʻonā e hoʻoponopono i kēia ma ka hoʻohui ʻana i kahi uhi kiʻiʻoniʻoni paʻakikī.
He kiʻekiʻe loa ka paʻakikī o ka ʻili o nā aniani aniani (ma ka maʻamau e waiho ʻia nā ʻili liʻiliʻi ke ʻoki ʻia e nā mea maʻamau), akā ʻaʻole kēia ka hihia no nā lens resin.Hiki ke ʻohi ʻia nā lens resin e nā mea paʻakikī, e hōʻike ana ʻaʻole hiki ke ʻaʻahu.
No ka hoʻomaikaʻi ʻana i ke kūpaʻa ʻana o ka lens, pono e hoʻohui i kahi uhi kiʻiʻoniʻoni paʻakikī i ka ʻili o ka lens.Hoʻohana pinepine ka uhi kiʻiʻoniʻoni paʻa i nā ʻātoma silika no ka mālama ʻana i ka paʻakikī, me ka hoʻohana ʻana i ka hopena paʻakikī i loaʻa kahi matrix organik a me nā ʻāpana ultrafine inorganic me nā mea silika.Loaʻa i ka kiʻiʻoniʻoni paʻakikī ka paʻakikī a me ka paʻakikī i ka manawa like (ʻo ka papa kiʻiʻoniʻoni ma ka ʻili o ka lens he paʻakikī, a ʻoi aku ka palupalu o ka substrate lens, ʻaʻole like me ke aniani hiki ke haki).
ʻO ka ʻenehana nui hou no ka uhi kiʻiʻoniʻoni paʻakikī ʻo ka hoʻoinu ʻana.ʻO ka uhi kiʻi paʻakikī he mānoanoa, ma kahi o 3-5μm.No nā lens resin me nā uhi kiʻiʻoniʻoni paʻakikī, hiki ke ʻike ʻia lākou ma ke kani ʻana o ka paʻi ʻana i ka pākaukau a me ka ʻōlinolino o ke kala lens.ʻO nā leki e hoʻopuka ana i kahi leo akaka a loaʻa nā ʻaoʻao ʻālohilohi i hoʻopaʻa ʻia.

E uhi i ka lens me kahi kiʻi anti-fouling.
ʻO ke kiʻiʻoniʻoni anti-reflective a me ke kiʻiʻoniʻoni paʻakikī nā ʻāpana kumu ʻelua no nā lens resin i kēia manawa.ʻO ka mea maʻamau, ua uhi mua ʻia ke kiʻi paʻakikī, a ma hope o ke kiʻi anti-reflective.Ma muli o nā palena o kēia manawa o nā mea kiʻiʻoniʻoni anti-reflective, aia kahi kū'ē ma waena o nā mana anti-reflective a me anti-fouling.No ka mea aia ke kiʻi anti-reflective i loko o kahi kūlana porous, ʻoi aku ka maʻalahi o ka hana ʻana i nā stains ma ka ʻili o ka lens.
ʻO ka hoʻonā e hoʻohui i kahi papa hou o ke kiʻi anti-fouling ma luna o ke kiʻi anti-reflective.ʻO ke kiʻi anti-fouling ka mea nui i nā fluorides, hiki ke uhi i ka porous anti-reflective film layer, hoʻemi i ka wahi pili ma waena o ka wai, ka aila, a me ka lens, ʻoiai ʻaʻole e hoʻololi i ka hana optical o ke kiʻi anti-reflective.
Me ka hoʻonui nui ʻana o nā koi, ua hoʻomohala ʻia nā papa kiʻiʻoniʻoni e like me ka polarizing film, anti-static film, blue light protection film, anti-fog film, a me nā papa kiʻiʻoniʻoni ʻē aʻe.ʻO nā mea lens hoʻokahi, ka helu kuhikuhi refractive lens like, nā mana like ʻole, a i loko o ka pahu like, me ka mea like, nā ʻano like ʻole o nā lens he ʻokoʻa kumu kūʻai, a ʻo nā uhi lens kekahi o nā kumu.Aia nā ʻokoʻa i ka ʻenehana a me ka maikaʻi o nā uhi.
No ka hapa nui o nā ʻano uhi kiʻiʻoniʻoni, paʻakikī i ka poʻe maʻamau ke ʻike i nā ʻokoʻa.Eia nō naʻe, hoʻokahi ʻano o ka uhi kahi e ʻike maʻalahi ʻia ai nā hopena: nā aniani pale ʻulaʻula uliuli (he ʻenehana i hoʻohana mau ʻia i nā lens pale kukui polū kiʻekiʻe).
Hoʻomaʻamaʻa kahi lens pale kukui polū maikaʻi i nā kukui polū pōʻino ma ka laulā 380-460nm ma o ka papa kiʻiʻoniʻoni pale kukui polū.Eia nō naʻe, aia nā ʻokoʻa i ka hana maoli ma waena o nā huahana mai nā mea hana like ʻole.Hōʻike nā huahana like ʻole i ka ʻokoʻa o ka pale ʻana i ke kukui polū, ka waihoʻoluʻu kumu, a me ka hoʻouna ʻana i nā māmā, e alakaʻi maoli ana i nā kumukūʻai like ʻole.

 

Pale i ka uhi ʻana o nā leki
Hoʻopili ʻia nā pale lens i nā wela kiʻekiʻe.Hoʻopili ʻia nā uhi ma nā lens resin ma hope a ua like lākou a pau i kahi nāwaliwali maʻamau: ua maʻalahi lākou i nā wela kiʻekiʻe.ʻO ka pale ʻana i nā uhi aniani mai ka pohā ʻana hiki ke hoʻolōʻihi i ke ola o nā lens.ʻO nā kaiapuni kikoʻī e pili ana i ka pōʻino i nā uhi lens:
1. Ke kau ʻana i nā makaaniani ma ka dashboard o ke kaʻa i ke awakea o ke kauwela.
2. Ke hoʻohana ʻana i nā makaaniani a i ʻole ke kau ʻana iā lākou ma kahi kokoke i ka wā e hoʻohana ana i ka sauna, e ʻauʻau ai, a i ʻole e hoʻopaʻa ʻia i kahi pūnāwai wela.
3.Cooking i loko o ka lumi kuke i ke kiʻekiʻe o ka aila wela;inā paʻi ka aila wela ma luna o nā aniani, hiki ke pohā koke.
4. I ka ʻai ʻana i ka ipu wela, inā paʻi ka sopa wela ma luna o nā lens, hiki ke naha.
5. Ka waiho ʻana i nā aniani kokoke i nā mea hana hale e hoʻoulu ai i ka wela no ka manawa lōʻihi, e like me nā kukui pākaukau, televise, etc.
Ma waho aʻe o nā helu i luna, he mea nui nō hoʻi e haʻalele i ka wai ʻakika ikaika a i ʻole ka wai alkaline e pale ai i nā kiʻi a i ʻole nā ​​lens mai ka ʻino.
He ʻokoʻa ke ʻano o ka ʻāʻī ʻana o nā uhi lens a me nā ʻōpala.Ma muli o ka ʻike ʻana i nā wela kiʻekiʻe a i ʻole nā ​​wai kemika, ʻo nā ʻōpala ka hopena ma muli o ka hoʻomaʻemaʻe kūpono ʻole a i ʻole ka hopena o waho.
ʻO ka ʻoiaʻiʻo, he huahana maʻalahi nā aniani.Pili lākou i ke kaomi, hāʻule, kulou, wela kiʻekiʻe, a me nā wai corrosive.

No ka pale ʻana i ka hana optical o ka papa kiʻiʻoniʻoni, pono e:
1. I ka wehe ʻana i kāu mau aniani, e hoʻokomo iā lākou i loko o kahi pahu pale a mālama iā lākou i kahi i hiki ʻole i nā keiki ke hiki.
2. E hoʻomaʻemaʻe i nā aniani me kahi mea hoʻomaʻemaʻe kūʻokoʻa i hoʻoheheʻe ʻia me ka wai anuanu.ʻAʻole ʻōlelo ʻia e hoʻohana i kekahi wai ʻē aʻe e hoʻomaʻemaʻe i nā aniani.
3. Ma nā wahi wela kiʻekiʻe (ʻoi loa i ka wā ʻauʻau a i ʻole ka kuke ʻana), pono e komo i nā aniani kahiko e pale ai i ka hōʻino ʻana i nā lens o nā aniani hou.
Hiki i kekahi poʻe ke holoi i ko lākou mau aniani me ka wai mahana i ka wā e holoi ana i ko lākou lauoho, maka, a ʻauʻau paha i mea e maʻemaʻe ai nā aniani.Eia nō naʻe, hiki i kēia ke hoʻopōʻino nui i nā uhi aniani a hiki ke hoʻohana ʻole ʻia nā lens.He mea nui ia e hoʻomaʻemaʻe wale ʻia nā aniani me kahi mea hoʻomaʻemaʻe kūʻokoʻa i hoʻoheheʻe ʻia me ka wai anuanu!

I ka hopena
me ka hoʻomau mau ʻana o ka ʻenehana uhi, ua holomua nui nā huahana maka maka i ka hoʻouna ʻana i ka māmā, ka pale ʻana, a me nā waiwai anti-fouling.ʻO ka hapa nui o nā lens resin, nā lens PC, a me nā lens acrylic hiki ke hoʻokō i nā pono o kēlā me kēia lā e pili ana i ka hoʻolālā uhi.
E like me ka mea i ʻōlelo ʻia ma luna, ʻo nā maka aniani nā huahana maʻalahi loa, e pili ana i ka ʻenehana uhi o ka papa kiʻiʻoniʻoni, ʻoi aku nā koi kiʻekiʻe no ka hoʻohana ʻana i ka mahana.ʻO ka hope, makemake wau e hoʻomanaʻo iā ʻoe: ke ʻike ʻoe i ka pōʻino i ka papa kiʻiʻoniʻoni o kāu mau aniani maka, e hoʻololi koke iā lākou.Mai hoʻomau i ka hoʻohana pono ʻole.Hiki i ka poino i ka papa ki'i'oni'oni ke ho'ololi i ka hana optical o nā lens.ʻOiai he mea liʻiliʻi ka lua o nā lens, he mea nui ke olakino o ka maka.
