Hoʻohana ʻia ke ʻano hana wiliwili no ka hana ʻana i kahi uhi lahilahi ma luna o nā substrate palahalaha. ʻO ka hopena o nā mea e uhi ʻia e waiho ʻia ma luna o ka substrate i wili ʻia me ka wikiwiki kiʻekiʻe ma kahi ākea o 1000-8000 rpm a waiho i kahi ʻāpana like.
Hana ka ʻenehana hoʻowili ʻana i ka uhi photochromic ma ka ʻili o ka lens, no laila e hoʻololi wale ke kala ma ka ʻili o nā lens, ʻoiai ʻo ka ʻenehana nui e hoʻololi i ke kala holoʻokoʻa.
Me ka hoʻololi ʻana o ka manawa a me ka hiki ʻana mai o ka pūnāwai, hoʻonui kā mākou mau hola o ka lā. No laila pono ke kūʻai ʻana i nā makaaniani e pale pono iā ʻoe iho i nā kukuna UV. Eia naʻe, ʻo ka huki ʻana i ʻelua mau aniani a puni hiki ke hoʻonāukiuki. ʻO ia ke kumu i loaʻa ai nā lens photochromic!
He kūpono kēia ʻano lens no nā pae like ʻole o ka mālamalama ma loko a ma waho. ʻO nā lens Photochromic nā lens akaka e pane ana i nā kukuna ultraviolet. No laila, loaʻa iā lākou ka hiki ke hoʻololi i nā kala ma muli o ke kukui
ʻO ke kukui polū he kukui ʻike ʻia me ka ikehu kiʻekiʻe ma ka laulā o 380 nanometers a 495 nanometers. Hoʻolālā ʻia kēia ʻano lens e ʻae i ke kukui polū maikaʻi e hele mai e kōkua iā ʻoe, a ma ka manawa like e pale aku i nā kukui polū pōʻino mai ka hele ʻana i kou mau maka.
Hiki i nā lens kukui anti-blue ke hōʻemi koke i nā hōʻailona o ka pilikia o ka maka kikohoʻe, ʻoi loa ke hana i ka pō. I ka hala ʻana o ka manawa, hiki ke hoʻohana ʻia nā mea pale polū i ka wā e hana ana i nā polokalamu kamepiula e hoʻomaʻamaʻa i kāu circadian rhythm a me ka pilikia o ka macular degeneration.
He mea maikaʻi loa nā lens ʻike kiʻekiʻe 1.67 no ka mea ʻoi aku ka wiwi a māmā ma mua o ka mānoanoa a me ka nui. ʻO ka 1.67 kiʻekiʻe-index lens mea he koho maikaʻi loa no nā kuhikuhi ma waena o +/-6.00 a me +/-8.00 sphere a ma luna o 3.00 cylinder. Hāʻawi kēia mau lens i nā optics maikaʻi, ʻoi aku ka ʻiʻo a me kahi hiʻohiʻona lahilahi, a hana maikaʻi lākou no nā papa drill-mauna ke ikaika loa ke kau ʻana no ka lens kuhikuhi waena.
