1. ʻO ka wikiwiki wikiwiki o ka hoʻololi ʻana, mai keʻokeʻo a i ka pōʻeleʻele a me ka hope.
2. Maikaʻi maikaʻi i loko o ka hale a i ka pō, e hoʻololi wale i nā kūlana māmā.
3. Ke kala hohonu loa ma hope o ka hoʻololi ʻana, hiki i ke kala hohonu ke piʻi i ka 75 ~ 85%.
4. Maika'i kala like 'ole ma mua a ma hope o ka ho'ololi.
ʻO ka palekana o ka lens PC.
Ke hopohopo nei ka palekana o ka maka, ʻo nā lens polycarbonate ka mea maikaʻi loa no kāu aniani.
ʻOi aku ka lahilahi a me ka māmā o nā lens polycarbonate a me Trivex ma mua o nā lens plastik maʻamau.Hāʻawi pū lākou i ka pale 100 pakeneka mai ke kukui UV ʻino o ka lā a hiki i ka 10 mau manawa ʻoi aku ka pale ʻana ma mua o nā aniani a i ʻole nā aniani.
ʻO kēia hui pū ʻana o ka hōʻoluʻolu māmā, ka pale UV a me ka pale ʻana i ka hopena e hoʻolilo i kēia mau lens i koho maikaʻi loa no nā aniani keiki.
Ka uhi AR.
--HC (ka uhi paʻa): No ka pale ʻana i nā lens i uhi ʻole ʻia mai ka pale ʻana
--HMC (paʻa paʻa paʻa / AR coating): E pale pono i ka lens mai ka noʻonoʻo ʻana, hoʻomaikaʻi i ka hana a me ke aloha o kāu ʻike.
--SHMC (super hydrophobic coating): E hana i ka lens i wai ʻole, antistatic, anti slip a me ka pale ʻana i ka aila.
