1.60 Lens optique ifunga urumuri rwubururu rwangiza hamwe na AR

Itara ry'ubururu rishobora kuba ingirakamaro kandi ryangiza amaso yacu.
Iyo ihuye nayo kumunsi, ifasha kongera kuba maso, no kunoza kwibuka. Iyo bigaragaye nijoro, bihagarika ibitotsi byacu.
Itara ry'ubururu rigizwe n'ibice bibiri - 'Nziza' ubururu-turquoise, uburebure bwumuraba uri hagati ya 450 - 500 nm, na 'Bad' ubururu-violet, buva kuri 380 - 440 nm.

Itara ry'ubururu-turquoise rirashobora kugirira akamaro ubuzima bwacu. Igenga injyana ya circadian (imbere 'isaha yumubiri' imbere), igenzura ukwezi kwacu-gukanguka, kubwibyo, ni ngombwa kugirango dusinzire neza.

Itara ry'ubururu-turquoise rishobora kandi kongera ibikorwa byubwonko, kunoza kwibuka, kumererwa neza, kuba maso no gukora mumutwe.

Kimwe nimirasire ya UV, guhura cyane nurumuri rwubururu-Violet birashobora kwangiza amaso. Irashobora kwangiza retina, kandi irashobora kongera ibyago byindwara zamaso nko guhindagurika kwimyaka (AMD), cataracte na Photokeratitis (cornea yaka izuba), bishobora gutera ubuhumyi bwigihe gito.

Ubushakashatsi bwerekanye ko guhura n’umucyo ukungahaye cyane ku bururu ku manywa biteza imbere imbaraga no kuba maso, bikongera umutima kandi bikanazamura umusaruro w'abakozi bo mu biro ndetse n'imikorere y'abanyeshuri. Ku rundi ruhande, nijoro, kutagira urumuri rukungahaye ku bururu birashobora gutuma umusaruro wa Melatonin, ari ubwoko bwa hormone bufasha kugenga ukwezi kwacu. Umusaruro no kurekura melatonine bifasha kugabanya umuvuduko wa metabolism.

Ibi bidufasha kuruhuka no gusinzira neza. Byongeye kandi, kutagira urumuri rwubururu nijoro binatera inzira zo kugarura umubiri nko gusana ingirabuzimafatizo zikenewe kugirango ubuzima bwiza kandi neza.
