Weird Visual Effects When Viewing Patterns

Hello all, I have noticed the strangest thing about my vision. We have a couch pillo with some weird colors and horizontal stripes. When I look at it, it looks b;lurry. Then I looked at some drapes that have gingham...they look like there was heat on them....you know the way heat looks on the road ahead?I don't notice vision issues except when looking at something with a pattern....but it is really freakin me out. i had an MRI a few weeks ago and it was normal. But this issue certanly is not. Anyone else ever had anythin like that?
 
Hi thereI have recently been in email correspondence with someone in the UK who has BFS and who also described visual symptoms too. RegardsSunib
 
I totally get this. One minute my left eye will be fine, then all of a sudden it will have like a haze in it. Then it will go away and won't happen again for 3 or 4 days. And blurriness comes and goes along with the twitches. No way the two things can't be related.
 
Wow! I thought I was the only one with vision issues accompanying whatever is happening to my body as far as the twitching goes!About a month before the twitching began, my right eye started having a small black dot that would follow my line of vision. It's pretty much constant, though it's worse in bright light and especially when I'm at work and staring at my computer screen.The other day I was looking at the horizontal blinds in my bedroom and they kind of looked like they were moving.Also, about a month into my twitching, my right eyeball, not my eyelid, felt like it was twitching constantly, or something. A very strange sensation. Of course when this was going on, the twitching in my body seemed to stop, probably because I was freaking about something else! :D) Also my right eye feels "numb" and tired sometimes, and I also had an episode where I thought my retina might be detaching.Crazy stuff. I'd love to feel normal again :(
 
Well, thank you. I am still quite concerned about it. I have only noticed that my vision is "odd" when I am looking at a pattern...and staring at my computer screen..which now seems to be very bright. I wish all I had was twitching!!!!!
 
Count me in 100% for eye issues that accompany my twitching issues. Looking at patterns always messes with my vision a bit. It seems to be some type of negative-after image, because the pattern distorts my vision for a short period of time. However, lights tend to flicker when I go from dark to light or vice versa, or when I watch a movie in the theater. I have floaters, temporary blind spots, small "lines of light", visual snow, etc. Like twitching, I've learned to live with the non-painful, non-debilitating, but potentially annoying symptoms.
 
Believe it or not, the lens in the eye is a pretty poor piece of kit.What happens when we see something is not as simple as we might think, there is no image on a screen in the back of the head like a cinema screen, what actually happens is that the optic nerve carries the signal to various specialised arrays of neurones that detect particular features of vision such as contrast, colour, movement, outline etc. the eye is also in constant motion we don't see the whole picture at once, only parts of it. What we percieve to be the complete picture in front of us is actually an illusion, it is a reconstruction and the brain is easily tricked, that is where all the optical illusions come from.Looking at patterns causes a lot of work, there is a lot of confusing detail there, the brain fills in some of it's own and doesn't get it quite right.It is not particularly unusual.
 
I started getting vision issues when my BFS started in 2005. The wavy line thing really bothers me. If I look at an American Flag the lines seem to be waving. Looking at siding on a house can do the same thing...anywhere there are a lot of straight lines close together. My eye Dr.'s explanation is dry eye syndrome. Actually 2 eye docs have told me that. It's definitely worse in the summer when my allergies are bad (therefore making my eyes drier). Do you have floaters? I also got those with my BFS, and they are also much worse when my eyes are drier.
 
Linda....Yes, yes and yes. I already had a few floaters. I had my vision tested, with pictures taken of my eyes and everything. Bottom line was I have 20/15 vision...maybe even 20/10 but they didn't test for that. Of course I am guilty of constantly self testing...and my allergies are terrible right now. The things I have noticed are that really b usy patterns give me trouble, and not even all the time. But they do look like they are moving, especially horizontal lines together.Also, and maybe this is anxiety or just me being crazy, but I could swear my low light vision is "off" . I get up in the middle of the night and, besides having balance issues (which don't bother me during the say), I almost feel like my visison is bad. Turn the lights on, and I'm fine. I don't know...this is all really weird but the day I saw couch pillows literally moving when I looked at them was a bad day. Thanks...
 
Don't know if any of this applies as well, but my eyes get worse as they get tired. Black and white checked tile is a nightmare! And if I look at a light in the darkness (headlights, stadium lights, etc.) the "burn" of the light seems to stay in my vision after the light goes away. And my eyes don't focus together as they used to. That one could be astigmatism or because I'm over 40, which the docs seem to think is when eyes get "older." My vision has been terrible since 2nd grade, so the fact that my hyper nervous system is affecting that isn't a shock, I guess. Just like my hyper nervous system is messing with my messed up left foot with the old injury.Funny thing is that i went gluten free 7 months ago and really haven't twitched. But this other stuff remains.
 
Hello everybody, apparently some migraine sufferers will develop what's called persistent positive visual phenomena, here's a link please check if the symptoms correlate with what you have, i know they do in my case, they appeared after the onset of migraine headaches which was probably triggered by bfs ...
 
I also have vision issues. I really wonder if this is all an auto-immune response. As an extreme example people with MS have optic neuritis and also complain of visual snow.thosewithvisualsnow.yuku.com
 
It actually might be the lack of something, maybe minute changes in the blood perfusion in the brain can starve the neurons of nutrients/oxygen and make them fire off randomly, some people with visual snow manifest abnormal spect scans, with reduced perfusion in the visual cortex, so structurally nothing is wrong but functionally (sodium, oxygen metabolism) there is. autoimmune disease sufferers get migraines with aura much more than the standard population, so maybe in our case it's a mild borderline rheumatic condition that has no name that manifests differently in everybody, i for example have 0 weakness or muscle pain but i get lots of visual stuff.
 
Something to do with the blood flow very possibly, but in me nothing that shows up in an MRI scan.I also have very interesting low vision abilities. I was in a mine museum recently where the darkness of the mine, ie no light at all was being demonstrated but I could see a very little by the flourescence from my watch. I used to be able to work in a photographic darkroom wearing tinted lenses, I guess I am wierd.
 
Blood flow doesn't show on MRI, it shows on SPECT and PET but those are mostly research tools and very harmful to your health, you must have a very good reason to take one of those.
 
Big yes here from me. I Have them all, the floaters, the dots, scotomas the stripes and-most scaring- eye migraines where one eye goes completely blind for about 20min-half hour.
