Aia ke kauwela, ua lōʻihi nā hola o ka lā a ikaika ka lā. Ke hele nei ma ke alanui, ʻaʻole paʻakikī ka ʻike ʻana i ka nui o ka poʻe e hoʻohana i nā lens photochromic ma mua. ʻO nā makaaniani Myopia ka piʻi nui o ka loaʻa kālā o ka ʻoihana kūʻai maka maka i nā makahiki i hala iho nei, a ʻo nā lens photochromic ka mea e hōʻoiaʻiʻo ai i ke kūʻai aku i ke kauwela. ʻO ka ʻae ʻia ʻana o nā lens photochromic e ka mākeke a me nā mea kūʻai mai mai nā pono like ʻole e like me ke kāʻei, pale māmā a me ka hoʻokele.
I kēia mau lā, nui aʻe ka poʻe i ʻike i ka pōʻino o nā kukuna ultraviolet i ka ʻili. ʻO ka pale lā, nā parasol, nā pāpale kiʻekiʻe, a me nā lima silika hau i lilo i mea pono no ka hele ʻana i ke kauwela. ʻO ka pōʻino o nā kukuna ultraviolet i nā maka, ʻaʻole paha e like me ka ʻili o ka ʻili, akā i ka wā lōʻihi, ʻoi aku ka nui o ka hōʻike pololei ʻana i nā hopena koʻikoʻi ma nā maka.
KE KUMU O KA HOOLOLI WAI: PHOTOCHROMISM
ʻO ka waihoʻoluʻu o ka lens photochromic e lilo i ʻeleʻele ma waho, a hiki i kahi kūlana e like me nā aniani, a ʻo ka hiʻohiʻona o ka hoʻi ʻana i loko o ka waihoʻoluʻu ʻole a me ke aniani e pili ana i ka manaʻo o "photochromic", e pili ana i kahi mea i kapa ʻia ʻo silver halide. I ka wā o ke kaʻina hana, hoʻohui nā mea hana lens i nā ʻāpana microcrystalline halide kālā i ka substrate a i ʻole ka papa kiʻiʻoniʻoni o ka lens. Ke hoʻomālamalama ʻia 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 kahi hapa o ka mālamalama ʻike ʻia; i ka wā e pōʻeleʻele ai ka mālamalama a puni, e hoʻāla hou nā iona kālā a me nā iona halide i ka halide kālā ma lalo o ka hoʻemi ʻana o ke keleawe oxide, a ʻoi aku ka māmā o ka waihoʻoluʻu o ka lens a hiki i ka hoʻi ʻana i ka waihoʻoluʻu ʻole a me ke aniani.
ʻO ka hoʻololi ʻana o ka waihoʻoluʻu o nā lens photochromic ma muli o ke ʻano o nā hopena kemika hiki ke hoʻohuli. ʻO ke kukui (me ka mālamalama ʻike ʻia a me ke kukui ultraviolet) kekahi hana koʻikoʻi i ka hopena. Ma keʻano maʻamau, pili pū ʻia e nā kau a me ke aniau, a ʻaʻole mālama mau i ka hopena paʻa a paʻa mau.
ʻO ka ʻōlelo maʻamau, i ka wā lā, ʻoi aku ka ikaika o nā kukuna ultraviolet, a ʻoi aku ka ikaika o ka hopena photochromic, a ʻoi aku ka hohonu o ka hohonu o ka wehe ʻana o nā lens. I nā lā ʻeleʻele, ʻoi aku ka nāwaliwali o nā kukuna ultraviolet, a ʻaʻole ikaika ka mālamalama, a ʻoi aku ka māmā o ke kala o ka lens. Eia kekahi, i ka piʻi ʻana o ka mahana, e maʻalahi ke kala o ka lens photochromic; ʻo ka mea ʻē aʻe, i ka wā e emi ai ka mahana, e lilo mālie ke kala o ka lens photochromic. ʻO kēia no ka mea ke kiʻekiʻe ka mahana, e hoʻemi hou ʻia nā ion kālā decomposed a me nā ion halide ma lalo o ka hana o ka ikehu kiʻekiʻe e hana i ka halide kālā, a e māmā ke kala o ka lens.
E pili ana i nā lens photochromic, aia nā nīnau maʻamau a me nā wahi ʻike:
1. E LOA AKU NEI NA LENSA PHOTOCHROMIC I KA MAMALAMA/MAKAMA MAI NA LENSA MAU?
ʻO nā lens photochromic o ka ʻenehana photochromic kiʻekiʻe me ka ʻole o ka waihoʻoluʻu hope, a ʻaʻole e ʻoi aku ka hewa o ka lawe ʻana i ka māmā ma mua o nā lens maʻamau.
2. No ke aha e hoʻololi ʻole ai nā lens PHOTOCHROMIC i ke kala?
ʻO ka hoʻololi ʻana o ka waihoʻoluʻu o nā lens photochromic e pili ana i nā mea ʻelua, ʻo ke kūlana māmā kekahi, a ʻo kekahi ke kumu hoʻololi kala (silver halide). Inā ʻaʻole ia e hoʻololi i ka waihoʻoluʻu ma lalo o ke kukui ikaika a me ke kukui ultraviolet, no ka mea paha ua luku ʻia kona kumu hoʻololi kala.
3. E NUI AKU NEI KA PALAPALA O NA LENO PHOTOCHROMIC MA muli o ka hoohana loihi ana?
E like me nā lens maʻamau, loaʻa i nā lens photochromic ke ola. Inā ʻoe e hoʻolohe i ka mālama ʻana, ʻoi aku ka nui o ka manawa hoʻohana ma mua o 2 a 3 mau makahiki.
4. No ke aha e poʻeleʻele ai nā lens PHOTOCHROMIC ma hope o ke komo ʻana iā lākou no ka manawa lōʻihi?
He ʻeleʻele nā lens Photochromic ma hope o ka ʻaʻahu ʻia ʻana no ka manawa lōʻihi, a ʻaʻole hiki ke hoʻihoʻi ʻia i ke aniani no ka mea ʻaʻole hiki i nā mea hoʻololi kala i loko o ia mau mea ke hoʻi i ko lākou kūlana mua ma hope o ka wehe ʻana, e hopena i ke kala hope. Loaʻa pinepine kēia ʻano i nā lens photochromic maikaʻi ʻole, akā ʻaʻole ia e loaʻa i nā lens photochromic maikaʻi.
5. No ke aha ka mea maʻamau i nā lens hina ma ka mākeke?
Hoʻopili nā lens hina i ka IR a me 98% o nā kukuna UV. ʻO ka pōmaikaʻi nui loa o ka lens hina, ʻaʻole ia e hoʻololi i ke kala kumu o ka hiʻohiʻona ma muli o ka lens, e hōʻemi pono ana i ka ikaika o ka māmā. Hiki i nā lens hina ke hoʻopaʻa like i kēlā me kēia ʻano kala, no laila e ʻeleʻele wale ka hiʻohiʻona nānā, akā ʻaʻole e ʻike ʻia ka chromatic aberration, e hōʻike ana i kahi manaʻo maoli a kūlohelohe. Eia kekahi, ʻo ka hina hina he kala kūʻokoʻa, kūpono i nā hui āpau o nā kānaka, a ʻoi aku ka kaulana i ka mākeke.
Inā makemake ʻoe e ʻike hou aʻe e pili ana i nā ʻano aniani a me nā kūkākūkā ʻoihana, e ʻoluʻolu e kipa i kā mākou pūnaewele a e kelepona mai iā mākou i kēlā me kēia manawa.
