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.
WHEN TO WORRY: 'If you stare at a n very bright light, such as the sun or a welding torch, for long enough, those images can burn into your retina, damaging your long-term sight, ' says Mr Constantine-Smith. If the multi-coloured lights last for longer than 30 minutes, it could signify a detached retina.
