Chii chinonzi bhuruu mwenje uye nei uchifanira kutenga bhuruu blocker mwenje lens?

Chiedza chebhuruu ndiyo inoonekwa spectrum ine mapfupi ekuona uye wepamusoro-soro simba, uye zvakafanana neiyo ultraviolet rays, mwenje webhuruu une zvese zvakanaka uye nengozi.

Kazhinji, masayendisiti anoti spectrum inoonekwa seye Electromagnetic radiation ne wavelengthes kubva muna 380 Nanometers (NM) mugumo webhuruu kune anenge 700 nm pamazana manomwe emugumo. (Nenzira, nanometer ndeye bhiriyoni imwe yemamita - iyo 0.000000001 metres!)

Chiedza chebhuruu kazhinji chinotsanangurwa sechiitiko chinoonekwa kubva pamakumi matatu neshanu kusvika mazana mashanu nm. Chiedza chebhuruu dzimwe nguva chinoputswa mubhuruu-violet mwenje (yakajeka 380 kusvika 450 nm) uye yebhuruu-turquoise mwenje (yakaenzana 450 kusvika 500 nm).

Saka, anenge chikamu chimwe chete muzvitatu chemwenje yese inoonekwa inoonekwa seyakakwirira-simba inoonekwa (Hev) kana "Blue" mwenje.

Pane humbowo hwebhuruu mwenje unogona kutungamira kune zvisingagumi zvisviniro. Zvinenge zvese zvebhuruu mwenje unopfuura zvakananga kumashure kusvika kumashure kweako retina. Kumwe kutsvagisa kwakaratidza mwenje webhuruu kunogona kuwedzera njodzi ye macular kuderera, chirwere cheRetina.
