ʻAʻole e like me nā aniani maka maʻamau a i ʻole nā aniani photochromic e hōʻemi wale i ka ʻōlinolino, kānana nā aniani UV400 i nā kukuna mālamalama āpau me nā nalu a hiki i 400 nanometers. Hoʻokomo pū kēia me UVA, UVB a me ke kukui polū ʻike ʻia me ka ikehu kiʻekiʻe (HEV).
I mea e noʻonoʻo ʻia ai he mau aniani UV, pono nā aniani e ālai i 75% a 90% o ka mālamalama ʻike ʻia a pono e hāʻawi i ka pale UVA a me UVB e ālai i 99% o ka radiation ultraviolet.
ʻO ke kūpono, makemake ʻoe i nā aniani lā e hāʻawi ana i ka palekana UV 400 no ka mea hāʻawi lākou i ka palekana 100% mai nā kukuna UV.
E hoʻomaopopo ʻaʻole i manaʻo ʻia nā aniani maka āpau he mau aniani pale UV. Loaʻa paha i kahi pālua o nā aniani maka he mau aniani ʻeleʻele, kahi mea hiki ke manaʻo ʻia e ālai i nā kukuna, akā ʻaʻole ia manaʻo e hāʻawi nā aka i ka pale UV kūpono.
Inā ʻaʻole i komo kēlā mau aniani maka me nā aniani ʻeleʻele i ka pale UV, ʻoi aku ka ʻino o kēlā mau aka ʻeleʻele no kou mau maka ma mua o ka ʻaʻahu ʻole ʻana i kekahi mau aniani pale. No ke aha mai? No ka mea, hiki i ke kala ʻeleʻele ke hoʻonui i kāu mau haumāna, e hōʻike ana i kou mau maka i ka mālamalama UV hou aku.
Pehea e hiki ai iaʻu ke ʻike inā loaʻa i kaʻu mau aniani ka palekana UV?
ʻO ka mea pōʻino, ʻaʻole maʻalahi ke ʻike inā he mau aniani pale UV kāu mau maka aniani a i ʻole nā aniani photochromic ma ka nānā wale ʻana iā lākou.
ʻAʻole hiki iā ʻoe ke hoʻokaʻawale i ka nui o ka pale ma muli o ke kala o ka lens, ʻoiai ʻaʻohe pili o nā kala lens a i ʻole ka pouli me ka pale UV.
ʻO kāu koho maikaʻi loa, ʻo ia ke lawe i kāu mau aniani i kahi hale kūʻai maka a i ʻole kahi ʻoihana hoʻāʻo loea. Hiki iā lākou ke hana i kahi hoʻāʻo maʻalahi ma kāu mau aniani e hoʻoholo ai i ka pae o ka pale UV.
A i ʻole ke koho maʻalahi ma ke kau ʻana i kāu ʻimi ma kahi mea hana kaulana a ʻoihana hoʻi e like me UNIVERSE OPTICAL, a koho i nā aniani maka UV400 maoli a i ʻole nā aniani photochromic UV400 mai ka ʻaoʻao.https://www.universeoptical.com/1-56-aspherical-uv400-q-active-material-photochromic-lens-product/.
