He aha ka Blue Light a no ke aha ʻoe e kūʻai ai i nā lens kukui blocker blue？

ʻO ke kukui polū ke kukui ʻike ʻia me ka lōʻihi hawewe pōkole a me ka ikehu kiʻekiʻe, a like me nā kukuna ultraviolet, loaʻa i ka kukui uliuli nā pōmaikaʻi a me nā pōʻino.

ʻO ka mea maʻamau, ʻōlelo ka poʻe ʻepekema ʻo ka spectrum māmā ʻike ʻia i loko o ka radiation electromagnetic me nā lōʻihi hawewe mai 380 nanometers (nm) ma ka hope polū o ka spectrum a ma kahi o 700 nm ma ka hopena ʻulaʻula.(Ma ke ala, ʻo ka nanometer he hoʻokahi piliona piliona o ka mika - ʻo ia ka 0.000000001 mika!)

ʻO ke kukui polū ma ke ʻano he kukui ʻike ʻia mai 380 a 500 nm.ʻO ke kukui polū i kekahi manawa ua hoʻohiolo hou ʻia i ke kukui uliuli-violet (ma kahi o 380 a 450 nm) a me ke kukui uliuli-turquoise (ma kahi o 450 a 500 nm).

No laila, ma kahi o ka hapakolu o nā kukui ʻike ʻia a pau i manaʻo ʻia ʻo ke kukui ʻike kiʻekiʻe (HEV) a i ʻole "uliuli".

Loaʻa nā hōʻike e hiki i ke kukui polū ke alakaʻi i nā loli mau.Aneane e hele pololei nā kukui polū a pau i ke kua o kou retina.Ua hōʻike ʻia kekahi mau noiʻi e hiki ke hoʻonui ʻia ke kukui polū i ka macular degeneration, kahi maʻi o ka retina.

Hōʻike ka noiʻi e alakaʻi i ka macular degeneration pili i ka makahiki, a i ʻole AMD.Ua ʻike ʻia kekahi noiʻi ʻana ua hoʻokuʻu ʻia ke kukui polū i ka hoʻokuʻu ʻia ʻana o nā molekala ʻona i nā cell photoreceptor.Hoʻopilikia kēia i ka hiki ke alakaʻi iā AMD.

I kekahi mau makahiki aku nei, ua kūkulu mākou i ka hanauna mua onā lens pale kukui uliuli.Me ka hana hou o ka ʻenehana i ka wā i hala, kā mākounā aniani pale uliulihoʻomaikaʻi ʻia e like me ka hiki ke ʻike ʻole ʻia.

ʻO kā mākoubpale kukui luenā leka uilaloaʻa i nā kānana e ālai a hoʻopaʻa i ke kukui polū.ʻO ia hoʻi inā hoʻohana ʻoekeia mau mealekiōesi ka nānā ʻana i kahi pale, ʻoi aku ka nui ma hope o ka pōʻeleʻele, hiki iā lākou ke kōkua i ka hōʻemi ʻana i ka ʻike ʻana i nā nalu ʻulaʻula uliuli e hiki ke mālama iā ʻoe a kōkua pū i ka hōʻemi ʻana i ke kaumaha o ka maka.Eia nō naʻe, ke koi nei kekahi poʻe i ke kukui polū mai nā polokalamu kikohoʻe ʻaʻole ke kumu o ka luhi maka.ʻO nā pilikia i hoʻopiʻi ʻia e ka poʻe ma muli o ka hoʻohana nui ʻana i nā polokalamu kamepiula.
