Chii chinonzi Blue light uye nei uchifanira kutenga blue blocker light lenses?

Chiedza chebhuruu ndicho chinooneka chiedza chine hupfupi hwewavelength uye chepamusoro-soro simba, uye zvakafanana nemwaranzi yeultraviolet, mwenje webhuruu une zvese zvinobatsira uye njodzi.

Kazhinji, masayendisiti anoti chivheneko chinooneka chinosanganisira mwaranzi yemagetsi ine wavelengths kubva pa380 nanometers (nm) pamucheto webhuruu we spectrum kusvika 700 nm pamucheto mutsvuku.(Nenzira, nanometer ibhirioni imwe yemamita - ndiyo 0.000000001 mita!)

Chiedza chebhuruu kazhinji chinotsanangurwa sechiedza chinooneka kubva pa380 kusvika 500 nm.Chiedza chebhuruu dzimwe nguva chinozoputswa kuita bhuruu-violet mwenje (inenge 380 kusvika 450 nm) uye yebhuruu-turquoise mwenje (inenge 450 kusvika 500 nm).

Saka, chinenge chikamu chimwe muzvitatu chechiedza chinooneka chinonzi high-energy kuonekwa (HEV) kana "blue" chiedza.

Pane humbowo mwenje weblue unogona kutungamira kukuchinja kwekuona zvachose.Chinenge mwenje wese webhuruu unopfuura wakananga kumashure kweretina yako.Imwe tsvakurudzo yakaratidza chiedza chebhuruu chinogona kuwedzera njodzi ye macular degeneration, chirwere che retina.

Tsvagiridzo inoratidza kuratidzwa kwechiedza chebhuruu kunogona kutungamira kune zera-ane hukama macular degeneration, kana AMD.Imwe ongororo yakawana mwenje webhuruu wakakonzera kuburitswa kwemamorekuru ane muchetura mumasero ephotoreceptor.Izvi zvinokonzeresa kukuvara kunogona kutungamira ku AMD.

Makore akati wandei apfuura, takagadzira chizvarwa chekutanga cheblue light blocking lenzi.Nekuvandudza tekinoroji munguva yakapfuura, yedublue blocking lensesdzinovandudzwa sechisikigo sezvinobvira kuti zvisaonekwe.

Yedublue light blockinglenziane masefa anovharira kana kutora chiedza cheblue.Zvinoreva kana ukashandisaizvilenzieskana uchitarisa pachidzitiro, kunyanya kwasviba, vanogona kubatsira kuderedza kuratidzwa kwemafungu ebhuruu emwenje anogona kukuchengeta wakamuka uye zvakare kubatsira kuderedza kushushikana kwemaziso.Nekudaro, vamwe vanhu vanoti mwenje webhuruu kubva kumidziyo yedhijitari haikonzeri maziso.Matambudziko anonyunyuta nevanhu anongokonzerwa nekunyanya kushandiswa kwemidziyo yedhijitari.
