Kuhihewa 1:
ʻO nā makaanianianiani a pau he 100% pale UV
E hoʻomaopopo mua kākou i ke kukui ultraviolet.Aia ka hawewe o ke kukui ultraviolet ma lalo o 400 uv.Ma hope o ka ʻike ʻia ʻana o ka maka, e hoʻopōʻino ia i ka cornea a me retina, e hopena i ka keratitis solar a me ka corneal endothelial pōʻino. Pono nā aniani kiʻekiʻe kiʻekiʻe e hiki ke komo a hōʻike paha i nā kukuna ultraviolet e pale i ka ʻike ʻana i nā maka.
ʻO nā aniani me ka hana anti-ultraviolet ma ke ʻano he nui nā ʻano kikoʻī:
1. E kaha “UV400″:
ʻO ia hoʻi, ʻo 400nm ka nalu kaʻawale o ka lens i nā kukuna ultraviolet, ʻo ia hoʻi, ʻo ka nui o ka nui o kāna transmittance spectral ma kahi hawewe ma lalo o 400nm ʻaʻole hiki ke ʻoi aku ma mua o 2%.
2. E kaha “UV”, “UV pale”:
E hōʻike ana he 380nm ka lōʻihi o ka hawewe pale o ka lens i nā kukuna ultraviolet.
3. E kaha “100% UV absorption”:
'O ia ho'i, 'o ka lens he 100% absorption o nā kukuna ultraviolet, 'o ia ho'i, 'a'ole i oi aku ka 'awelika o ka transmittance ma ka laulā ultraviolet ma mua o 0,5%. he hana pale i na kukuna ultraviolet ma ke ano maoli.
Kuhihewa 2:
ʻOi aku ka maikaʻi o nā makaaniani polarized ma mua o nā makaaniani maʻamau
ʻO ka mea i kapa ʻia nā makaaniani polarized, ma kahi o nā hana o nā aniani, hiki ke hoʻonāwaliwali a hoʻopaʻa i ka pōʻino.
ʻike ʻia ka mālamalama, ka ʻālohilohi, ka noʻonoʻo pono ʻole o nā mea, a me nā mea ʻē aʻe, a hāʻawi i ke koʻi hoʻouna o ke ala pololei i ka
maka e nānā a hoʻolilo i ka ʻike i waiwai Nā pae, ʻoi aku ka maʻalahi o ka ʻike a ʻoi aku ka kūlohelohe.ʻO nā polarizer maʻamau
kūpono no nā hana o waho e like me ke kaʻa ʻana, ka lawaiʻa, ka holo ʻana, ka wai keʻokeʻo, a me ka ski.
ʻOi aku ka pōʻeleʻele o nā lens polarizer, ʻaʻole pono e ʻaʻahu iā lākou i nā lā ao a i loko paha.Pono ʻoe e koho
kekahi mau makaaniani maʻamau e pale i kou mau maka mai nā kukuna ultraviolet.
