Causes of flashes in your vision. As the vitreous âgelâ within your eye shrinks, it may pull on the retina (the focusing surface at the back of your eye). If the retina is peeled away from the back of the eye, it can cause flashes of light in your vision to occur. A retinal tear or detached retina is a serious and potentially sight-threatening condition.
Not very bright at all. The process of becoming blinded by light is because the iris contracts when the light level increases. The reverse process of dilation is slow for humans, so the return to darkness leaves your eye with insufficient light coming in to see in the environment you suggest. This isn't a binary factor.
