Me ka ʻoi aku ka lōʻihi o nā hola o ke ao a ʻoi aku ka ikaika o ka lā, e hele ana ma nā alanui, ʻaʻole paʻakikī ke ʻike i ka nui o nā poʻe e hoʻohana ana i nā lens photochromic ma mua.Ke ulu nui nei nā makaaniani lāʻau i ka ʻoihana kūʻai maka maka i nā makahiki i hala iho nei, a ʻo nā lens photochromic e mau ana i ke kumu kūʻai kūʻai kauwela.ʻO ka mākeke a me ka ʻae ʻana o nā mea kūʻai aku i nā lens photochromic mai ko lākou ʻano, pale māmā, a me nā pono e pili ana i ka hoʻokele.
I kēia mau lā, ʻoi aku ka nui o ka poʻe i ʻike i ka pōʻino o nā kukuna ultraviolet i ka ʻili.ʻO ka pale lā, nā pālule, nā pāpale baseball, a me nā uhi lima silika hau i lilo i mau mea pono no nā huakaʻi kauwela.ʻAʻole ʻike koke ʻia ka pōʻino o nā kukuna UV i nā maka, akā i ka wā lōʻihi, hiki i ka ʻike nui ke alakaʻi i nā hopena ʻoi aku ka koʻikoʻi.Ua hōʻike ʻia nā maʻi o ka maka e like me ka cataracts a me ka macular degeneration e pili ana i ka makahiki i ka loaʻa ʻana o nā loulou pololei a i ʻole nā loulou i ka ʻike UV.I kēia manawa, ʻaʻohe manaʻo o ka poʻe Kina i ka manaʻo o "ka wā e hoʻohana ai i nā aniani" e pili ana i nā kūlana o ka lā.ʻO ka manawa pinepine, ʻo ke kaiapuni o waho e pono ai i ka pale māmā, akā manaʻo ka hapa nui o nā mea kūʻai aku he "pono ʻole" a koho ʻaʻole e ʻaʻahu iā lākou.E kūʻē i kēia kāʻei kua, nā lens photochromic, e hāʻawi ana i ka hoʻoponopono ʻana i ka ʻike a me ka pale māmā me ka pono ʻole o ka wehe ʻana e like me nā makaaniani maʻamau i nā wahi like ʻole, e ʻae ʻia i waena o nā poʻe he nui.
ʻO ke kumu o ka hoʻololi kala i nā lens photochromic ma muli o "photochromism."Ma nā hoʻonohonoho o waho, ʻeleʻele kēia mau lens e like me nā makaaniani a hoʻi hou i ka akaka a me ka akaka i loko o ka hale.Hoʻopili ʻia kēia ʻano i kahi mea i kapa ʻia ʻo ka halide kālā.I ka wā o ka hana ʻana, hoʻokomo nā mea hana lens i ke kumu a i ʻole ka papa kiʻiʻoniʻoni o nā lens me nā microcrystals halide kālā.Ke hōʻike ʻia i ke kukui ikaika, hoʻoheheʻe ʻia ka halide kālā i loko o nā ion kālā a me nā ion halide, e komo i ka hapa nui o ke kukui ultraviolet a me kekahi kukui ʻike ʻia.Ke pōʻeleʻele ke kukui i loko o ke kaiapuni, hui hou nā ion kālā a me nā ion halide i loko o ka halide kālā ma lalo o ka hana hoʻohaʻahaʻa o ka copper oxide, e hoʻomāmā ai ka waihoʻoluʻu a hiki i ka lilo ʻana i akaka hou.
ʻO ka hoʻololi ʻana o ka waihoʻoluʻu i nā lens photochromic ka hopena o ke ʻano o nā hopena kemika hiki ke hoʻohuli ʻia, me ka māmā (me ka ʻike ʻike a me ke kukui ultraviolet) e pāʻani ana i kahi kuleana koʻikoʻi i kēia mau hopena.ʻO ka mea maʻamau, ʻo ka maikaʻi o ke kaʻina hoʻololi kala e hoʻopili ʻia e nā kau a me nā kūlana o ka wā, no laila ʻaʻole ia e mālama mau i ka hopena paʻa a paʻa.
ʻO ka mea maʻamau, i ka wā lā, ʻoi aku ka ikaika o nā kukuna ultraviolet, e alakaʻi ana i kahi hopena photochromic ikaika loa, a ʻeleʻele nui nā lens.ʻO ka ʻokoʻa, i nā lā ʻeleʻele, ke nāwaliwali nā kukuna UV a me ka ikaika o ka māmā, ʻike ʻia nā lens.Eia kekahi, ke piʻi aʻe ka mahana, e māmā mālie ke kala o nā lens photochromic.ʻO ka mea ʻē aʻe, ke hāʻule ka mahana, e pōʻeleʻele mālie nā lens.ʻO kēia no ka mea ma nā mahana kiʻekiʻe, ua hoʻemi ʻia nā ion kālā a me nā halide i hoʻoheheʻe ʻia ma mua i ka halide kālā ma lalo o ka ikehu kiʻekiʻe, e hoʻomālamalama ana i ke kala o nā lens.
E pili ana i nā lens photochromic, aia kekahi mau nīnau maʻamau a me nā wahi o ka ʻike:
He haʻahaʻa haʻahaʻa ka transmittance/mālamalama māmā o nā lens photochromic i hoʻohālikelike ʻia me nā lens maʻamau?
ʻAʻole waihoʻoluʻu loa nā lens photochromic kiʻekiʻe ke hoʻāla ʻole ʻia a ʻaʻohe haʻahaʻa haʻahaʻa o ka uila ma mua o nā lens maʻamau.
No ke aha e loli ʻole ai nā lens photochromic?
ʻO ka nele o ka hoʻololi kala i nā lens photochromic e pili ana i nā kumu ʻelua: nā kūlana kukui a me ka mea hana photochromic (silver halide).Inā ʻaʻole lākou e hoʻololi i ka waihoʻoluʻu me ka mālamalama ikaika a me ka hoʻoheheʻe ʻana o UV, ua pōʻino paha ka mea hana photochromic.
E piʻi aʻe paha ka hopena hoʻololi kala o nā lens photochromic i ka manawa?
E like me nā lens maʻamau, loaʻa ke ola o nā lens photochromic.Me ka mālama pono, mau lākou ma mua o 2-3 mau makahiki.
No ke aha e ʻeleʻele mau ai nā lens photochromic i ka manawa?
Inā pōʻeleʻele nā lens photochromic i ka wā lōʻihi a ʻaʻole hiki ke hoʻi hou i ke aniani, no ka mea ʻaʻole hiki i kā lākou mea hana photochromic ke hoʻi i kona kūlana mua ma hope o ka hoʻololi ʻana i ka waihoʻoluʻu.ʻOi aku ka maʻamau o kēia ʻano i nā lens haʻahaʻa, ʻoiai ʻaʻole e loaʻa kēia pilikia i nā lens photochromic maikaʻi.
No ke aha i maʻa mau ai nā lens hina ma ka mākeke?
Hiki i nā lens hina ke komo i ka infrared a me 98% o nā kukuna UV.ʻO ka pōmaikaʻi nui loa o nā lens hina, ʻaʻole lākou e hoʻololi i nā kala kumu o nā mea, e hōʻemi pono i ka ikaika māmā.Hoʻopili like lākou i ka mālamalama ma nā ʻano kikoʻī a pau, no laila ʻoi aku ka ʻeleʻele o nā mea akā ʻaʻole me ka ʻokoʻa o ka waihoʻoluʻu, hāʻawi i kahi ʻike maoli a kūlohelohe.Eia kekahi, ʻo ka hina hina he kala kū ʻole, kūpono i nā mea a pau, e ʻoi aku ka kaulana i ka mākeke.
