Blue light in vision
 

Its now more than two years since I had my concussion. Many of my symptoms have got better, but I still have many of them just at little less. There is however one symptom that hasnt changed at all, I see blue light in my vision. The light is like a glow, kind of like lights from a neon sign. They occure only when its dark and when I am outside and in conjunction with other bright lights such as car lights and street lights. They only last for less than a second, but I can have several with a few seconds between. I see them frequently when I am driving at night. I have tried to cover one of my eyes to see which eye is affected, but it seems like I only see it when I use both my eyes. Does anyone have something like this or know what is wrong?

Hello troublehead: I'm sorry I probably don't have much to offer with regard to this. My poor head has taken a beating over the years. (I'll spare you the details.) But I have not had the experience you describe. One thing I have had, though (which I think may have been caused by some of the beating my head has taken) is a detached retina in one eye. It caused quite a few odd visual abnormalities. So, when I read your post, I wondered if you've had your eyes examined by an ophthalmologist. You probably have. But, if not, you might consider doing so. My best wishes to you... :)

There are lots of cars with halogen headlights that appear blue for moments with just the right angle through the headlight lens. I would suspect that some streetlights use the same halogen technology to reduce energy consumption.

I have had my eyes examined, not by a Ophthalmologist though, but by a Optometrist. He didnt find anything wrong. Thanks for your input.

Its not an issue with colored lights from headlights or other sources and I did not have this before my accident. In fact the blue light I see can occure without any strong lights as well, but headlights and street lights are usually what trigges it. The lights I see are in different shapes, they can på smaller dots or they can be bigger like a smear across a portion of my field of vision. On rare occasions I also see something similier in bright daylight, but the color is then either pink or yellow.

You could be having a visual migraine without pain but I doubt it.
There are many things we notice after a concussion that we think are from the concussion but are really just something that we did not notice before the concussion. The changes in how the brain filters out aberrations and distractions in our senses can cause us to NOTICE things that we never noticed before.

Many will notice floaters and become alarmed. But, 999 times out of 1000, those floaters are normal and it is just that we never paid attention to them because our brain was better at ignoring them.

Strongly recommend an appt with a behavioural optometrist - their testing and questioning will be comprehensive and more importantly they understand our problems. Well worth networking to find one.
Best of.

TH,

I see a series of blue lines running from center to lower outside corner of my eyes when I close my eyes at night, it happens when I close my eyes to go to sleep, including when I lay back down after peeing which is aplenty since my accident.

They do not stay, just a flash and only since my accident.

Yes, but if the brain, after a concussion, fails to filter out these things, then there is a damage some place caused by the concussion. Its not normal to see things like this.

Thank you, I'll try to find one.
