Blue light from digital devices speeds blindness

Blue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo. Photoreceptor cells in the retina need molecules called retinal to sense light and trigger a cascade of signaling to the brain. You need a continuous supply of retinal molecules if you want to see. blue light exposure causes retinal to trigger reactions that generate poisonous chemical molecules in photoreceptor cells. It’s toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves. Photoreceptor cells do not regenerate in the eye.

does all blue light has this problem? if we live in a blue painted house does it affect our eyes? please stop using digital equipments in dark.
