Is it normal to see blue spots?

The blood flow in your eye can absorb the blue light from the sky, causing the appearance of a moving white light. These strange spots should disappear quickly, leaving you with your normal vision.

Why do I see blue dots in the dark?

Can anxiety cause spots in vision?

Anxiety can cause tunnel vision and visual snow; and perhaps other visual spots as well. In addition, floaters, tunnel vision and visual snow can cause you to become worried, anxious and hypervigilant because you think they are a symptom of a serious eye problem.

Is it normal to see colored spots?

The colored streaks that you see after accidentally looking at the sun or other bright light source are not the same as flashes and floaters. This effect happens when the photosensitive cells of your retina are overwhelmed by the intense light coming through the front of the eye.

Is visual snow serious?

Initial functional brain imaging research suggests visual snow is a brain disorder. Visual snow is a chronic condition, sometimes highly disabling, uncommon condition that is in need of collaborative research and lateral thinking to make progress towards understanding, treatment and cure.

Can dehydration cause eye flashes?

Dehydration, stress, lack of sleep, caffeine and certain foods are typical triggers for ocular migraines. When someone describes their flash stemming from only one eye and it is a quick flash usually only seen in the dark almost like a flash from a camera then I often attribute this to the vitreous gel.
