ʻO ka High Index (1.74 index) lens material ka mea ʻoi aku ka lahilahi a me ka māmā loa o ka lens ma ka honua, a ʻo ia ka koho maikaʻi loa no nā ʻōlelo kuhikuhi mana kiʻekiʻe, a i ʻole ka mea makemake i ka lens thinnest no kā lākou noi. Loaʻa iā lākou ka pale 100% UV a hana maikaʻi me ka hapa nui o nā ʻano kiʻi ma waho o ka rimless drilled.
No ka ʻike maikaʻi a me ka hiʻohiʻona maikaʻi, he manaʻo maikaʻi e loaʻa i kahi uhi aniani anti-reflective (AR coating) i hoʻopili ʻia i nā lens kiʻekiʻe. Hoʻouna nā lens kiʻekiʻe i uhi ʻia e AR i ka 99.5 pakeneka o ka mālamalama i ka maka no ka ʻike maikaʻi loa.
A ma muli o ka hoʻopau ʻana o ka uhi ʻana o AR i nā noʻonoʻo ʻana o ka lens, ʻike ʻia nā lens-index kiʻekiʻe i ʻike ʻole ʻia, no laila ʻike nā poʻe ʻē aʻe i kou mau maka, ʻaʻole i kou mau lens.
Loaʻa ka nalu a me ka ikehu mai ka 380 nm (ka ikehu kiʻekiʻe a hiki i ka 500 nm (ka ikehu haʻahaʻa).
No laila, ʻo kahi hapakolu o nā kukui ʻike ʻia he kukui polū
Hoʻokaʻawale hou ʻia ke kukui polū i kēia mau pūʻulu (kiʻekiʻe i ka ikehu haʻahaʻa):
· Māmā ʻulaʻula (ma kahi o 380-410 nm)
· Māmā ʻulaʻula-ʻulaʻula (ma kahi o 410-455 nm)
· Māmā polū-turquoise (ma kahi o 455-500 nm)
Ma muli o ko lākou ikaika kiʻekiʻe, ʻoi aku ka maikaʻi o nā kukuna violet a me ka uliuli-violet e hōʻino i ka maka. No kēia kumu, ua kapa ʻia kēia mau kukuna (380-455 nm) he "kukui polū pōʻino."
ʻO nā kukui kukui polū-turquoise, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka liʻiliʻi o ka ikehu a ʻike ʻia e kōkua i ka mālama ʻana i kahi pōʻai hiamoe maikaʻi. No kēia kumu, ua kapa ʻia kēia mau kukuna (455-500 nm) i kekahi manawa he "mālamalama polū maikaʻi."
Aia nā kukuna ultraviolet ʻike ʻole ʻia (UV) ma mua o ka hopena kiʻekiʻe (violet) o ke kukui ʻulaʻula uliuli ʻO nā kukuna UV he mau lōʻihi hawewe pōkole a ʻoi aku ka ikaika ma mua o ke kukui uliuli ʻike ʻia. Ua hōʻike ʻia ka radiation UV i ka pōʻino i nā maka a me ka ʻili.
Hana ʻia nā lens hōʻemi kukui polū me ka hoʻohana ʻana i kahi puaʻa patent i hoʻohui pololei ʻia i ka lens ma mua o ke kaʻina hoʻolei. ʻO ia hoʻi, ʻo ka mea hoʻohaʻahaʻa kukui polū kekahi ʻāpana o nā mea lens holoʻokoʻa, ʻaʻole wale i kahi kala a i ʻole ka uhi. ʻO kēia kaʻina hana patent e hiki ai i nā kukui polū e hōʻemi ana i nā lens e kānana i ka nui o nā kukui polū a me nā kukui UV.
1. Aia ke kukui uliuli ma na wahi a pau.
2. He uliuli nā kukuna HEV.
3. ʻAʻole maikaʻi ka maka i ka pale ʻana i ke kukui uliuli.
4. Hiki ke hoʻonui i ka pōʻino o ka macular degeneration i ka ʻike ʻana i nā kukui polū.
5. Hāʻawi ke kukui polū i ka pilikia o ka maka.
6. ʻOi aku ka nui o ka pale ʻana i nā kukui polū ma hope o ka ʻoki ʻana i ka cataract.
7. ʻAʻole maikaʻi nā kukui uliuli a pau.
