ʻO ke aniani photochromic kahi aniani e loli koke ke kala me ka loli ʻana o ke kukui o waho. Hiki iā ia ke lilo i pouli koke ma lalo o ka lā, a emi nui kona transmittance. ʻO ka ikaika o ke kukui, ʻoi aku ka pouli o ke kala o ke aniani, a ʻo ka hope. Ke hoʻihoʻi ʻia ke aniani i loko o ka hale, hiki i ke kala o ke aniani ke mae koke i ke ʻano moakaka mua.
ʻO ke kumu nui o ka hoʻololi ʻana o ke kala i loko o ke aniani e kuhikuhi ʻia ana ka loli ʻana o ke kala. He hopena hoʻohuli kemika ia.
Ma keʻano laulā, aia ʻekolu ʻano ʻenehana hana lens photochromic: in-mass, spin coating, a me dip coating.
ʻO ka aniani i hana ʻia ma ke ʻano o ka hana nui ʻana he mōʻaukala hana lōʻihi a paʻa. I kēia manawa, hana nui ʻia me ka index 1.56, loaʻa me ka ʻike hoʻokahi, bifocal a me multi-focal.
ʻO ka uhi ʻana o ka wili ka hoʻololi nui ʻana i ka hana ʻana o nā aniani photochromic, ka loaʻa ʻana o nā aniani like ʻole mai 1.499 a i 1.74. ʻOi aku ka māmā o ke kala kumu o ka uhi ʻana o ka wili photochromic, ʻoi aku ka wikiwiki, a ʻoi aku ka ʻeleʻele a me ke kala like ma hope o ka hoʻololi ʻana.
ʻO ke uhi ʻana i ka lens ke hoʻokomo ʻana i ka lens i loko o ka wai o ka mea photochromic, i mea e uhi ai i ka lens me kahi papa photochromic ma nā ʻaoʻao ʻelua.
Ua hoʻolaʻa ʻia ʻo Universe Optical i ka ʻimi ʻana i nā aniani photochromic maikaʻi loa. Me ka hale hana R&D ikaika, ua loaʻa kekahi mau moʻo o nā aniani photochromic me ka hana maikaʻi loa. Mai ke ʻano photochromic in-mass 1.56 kuʻuna me ka hana hoʻololi kala hoʻokahi, i kēia manawa ua hoʻomohala mākou i kekahi mau aniani photochromic hou, e like me nā aniani photochromic blueblock a me nā aniani photochromic spin coating.
