Has never lasted more that 30 minutes to and hour and once gone.
Looks like ceiling fan in peripheral vision.
When i un focus my eyes when looking at lights i can see it as well.
Mainly artificial light would seem to shimmer a bit.
Starting 4 years ago when i took a very bad buck from a 3yo horse i was training i have experienced what seems like pinwheels ceiling fans kaleidoscope colors in my vision.
I ll explain a little more just in case if you have an idea what s going on and need more information.
Like if someome lit somepaper on fire and it was bowing in the wind.
This seems silly to bring up but otoh who knows maybe others have experienced this.
I occasionally have this flickering in my peripheral vision that is just like the shadow that a ceiling fan with a light on it throws on the ceiling.
Sometimes its peripheral sometimes the effect is in a shape like a circle directly in my line of sight.
I m not going insane i think out of the corner of my right eye i can see something that appears to be a spinning color blob my mind registers it as a ceiling fan but when i look at it it moves and there s no reflective surface that could reflect it.
I only had the wavy water like vision in part of my vision in my left eye it was as if the center of my vision was fine and that was circled by the wavy vision i could see color and light but it was like i was under water looking up and someone was making the water ripple but only an outer circle.
It is something like viewing things through a rotating fan blade which would be revolving about 150 rpm.
I had an occurence a few years back when it seemed i was being swarmed by a bunch of black ash.
When my eyes are in this condition it is very difficult to read because i must slow my rate of comprehension while my brain makes out words behind the flashings.
I also have static look on the periphery of my vision on the entire right half of my left eye toward my nose.
Sometimes it s just a blotch.
Then when i look in the way of the shimmering it usually stops.
It was wierd then faded.
I have 20 20 vision and can even see in the pitch black darkness.
The first time it happened i went to the er but they said i just had a headache i did have one the worst i had ever had they.
I had laser for a retinal hole almost 3 weeks ago and i have a black blind spot 4 black dots but i don t see them all of the time.
What do you mean by ceiling fan effect.
Does anyone else see flickering in their peripheral vision.
The thing is that sometimes my vision seems to vibrate a little mostly in my peripheral vision it seems to be happening mainly when coming from a dark area and entering a bright one but this isn t always the case.
