Hi, new here, dunno how I found this place, simple site name but seems hard to find :P

Anyway it’s the best place I found to ask a few questions.

These are all to do with sight and may seem strange, I have normal vision (I think) but I notice more than most seem to.

When you look at something plain light and bright, do you see these small particles like bright streaks that move about in a random but smooth flowing way?
They’re almost like small atomic particles or something that streak then disappear while new ones reappear and it goes on all the time, though you won’t notice it with lots of different colours in any mess, just plain light surface.

Also I noticed a strange thing when I look through my fingers or any object that has two surfaces close together I see, dark lines, almost like veins or fork lightning, which moves following the surface angle. I did think it was the dark around the light making me see the veins in my eye but that just isn’t the case as it moves following the surface, oh and to see it well you have to move your fingers or object back and forth slightly in a steady motion.

Also I can see when doing the same thing, light bending slightly and sometimes red or blue shifting but that doesn’t seem possible because that’s only possible from a strong gravity.

These are some weird things I have noticed and I have to know if anyone else has noticed anything similar?

Welcome Mart.

I think you're in the wrong section. You need the biology one.

I'm Thor, one of the funny ones here. Hope you enjoy your stay:D

Hi, thx, i wasn't sure which forum this belongs to. :rolleyes:

Hey Mart! Welcome to SciForums! :D I'm Blue. Please keep your hands and feet inside the cart at all times. lol :)

I thought I was the only one going crazy, because I have sort of the same "vision" too!

Sometimes, when I'm lying in bed, I stare at the ceiling and look at the streaks of light coming through between the blinds. If I look hard enough, but not concentrate, I can make the light disappear completely, and put the entire room into total darkness.

Or, if I'm sitting at the public bus terminal, and stare at the tiles on the floor, I can see the illusion of waves and ripples, as if the entire floor were composed of Jello, and someone was bouncing on top. Then, I take the waves and push them into the centre, where it turns into a vortex, and I can actually see the edges of the conical shape lifting up and becoming 3-dimensional!

Or maybe I'm just going crazy http://www.uniquehardware.co.uk/server-smilies/contrib/Bizkit/confused.gif :D

lol, I have seen all the same types of things you have too!

Once when playing some sport in school I had a very dizzy spell and everything went really bright, coz im tall the doctor said it was the blood not getting to my head :P, but anyway when I had to sit down and close my eyes I opened them and looked at the gravely path and some of the stones glowed luminescent blue as if they had light coming from them but not the others.

lol, just another weird thing I seen :P

Oh also try what I said and look through a gap between your fingers and move it back and forth quickly but smoothly and only a little. Tell me if you see the black lines, it happens every time and they stand out really well, I really want to know what’s causing it!

Welcome to sciforums, mart.

The symptoms you describe are common. You need to go to an eye doctor to have it checked. No one here is a medical physician so legally we can not proscribe anything for you. The seeing of bits of light specks is commonly refered to as "floaters".

Hi Mart welcome, you can call me __________ or ____ for short. :).
Anyway I think you can solve your problem by staying away from LSD. :D

If you stare at the a surface with something blocking your vision a little, (i.e. look at the floor behind a table leg) if you try looking through the floor, then after a while, one eye will sort of paste in the information that it sees behind the leg that the other eye doesn't, thus making it look like the leg has disapeared! Or if it is a patterned floor, your brain will fill in the patterned section, but it will look sort of funny... Anyone else try this?

Its not an eye problem of any kind, its just some thing that i noticed when concentrating. Did you try what i said?

Oh also try what I said and look through a gap between your fingers and move it back and forth quickly but smoothly and only a little. Tell me if you see the black lines, it happens every time and they stand out really well, I really want to know what’s causing it!

Ok, I'm doing it right now...noope, sorry dude, I can't see any black lines. http://www.uniquehardware.co.uk/server-smilies/contrib/dvv/sconf.gif All I see are my fingers getting blurry, because I'm moving them quickly. :D I think it may be your eyes (don't get mad! :eek: ). Or maybe it's my eyes, since I have one near-sighted and one far-sighted. (I'm weeeird) http://216.40.241.68/contrib/corky/smilies27.gif

Me too, :D It's like a light-headed, woozy feeling, eh? Sometimes, I black out for a fraction of a second too, like my eyes are wide open, but I see pitch black. It was scary, I blacked out while walking once, just for a second, but it felt like an eternity. :eek:

Yep, and I think there's a scientific explanation behind it too. I think it's because each eye sees a slightly different image than the other, because they are set apart. Therefore, we have periphial vision, and can see depth. I've tried it before, when I'm lying down and one eye can see the top of the blanket and the other one can't, so the images meld and fuse into this strange transparent image. From one eye's point of view, I can touch the blanket, but in the "layered" point of view, the other eye thinks there is nothing there.

Ok try looking through the same gap between your fingers and move it about a hands distance away from your nose and look at the monitor, move it and you should see the light bend almost like it’s being magnified (focus at the monitor) and also I can just about see the thin dark lines as well. :)

Apparently you guys are able to manage the filtering mechanism of your hippocampus and hence the results...

have fun...there may not be any value other than having fun...like double joints etc. I used to filter out sound in a crowded place, it helped me to zero in to voices from a distance....may be you can find some application that is useful...

Oh my, quite odd. Guess what I can do? If i'm lying in bed and close one of my eyes then the pillow is close, but if i close the other eye, its far away!

Oh my god!



j/k

lol :)

I have seen some odd things when staring at bright lights though.

*tries again and again* Sorry, Mart, I can't see what you're describing...all I see are blurry shapes that are my fingers and the monitor. :D

i have a good idea what you are experiencing it is simply defocusing your eyes. For example staring at a candle and concentrate long enough and everything seems to disappear for you or with waving your hand in front of the moniter like you describe I bet it doesn't work if you try focusing on your hand and not behind it cause when you focus behind your hand the two eyes see two seperate images of your hand and as they move back and forth it blurs two images so that you see black lines which are really just the transparent appear images of your hands from your eyes being defocused that is pretty much it. Looks like vibrating strings right?

I can see into the ultraviolet spectrum to the extent that flowers in daylight look quite different to me than to an average person.

for example dark centers in flowers are visible to me but few others.

When you look at something plain light and bright, do you see these small particles like bright streaks that move about in a random but smooth flowing way?

I think I know what you're talking about. When I look up at a clear blue sky on a sunny day I see tiny, translucent, dougnut-like figures floating about. Also, I can somehow make my room appear totally dark at night, like %BlueSoulRobot% mentioned, but I think it's just my brain involuntarily focusing my eyes, and, WOAH! When I look at the spaces between the wood on the desk, everything goes all wobbly.

Hey! I saw the black lines, there at the tips of your fingers, %BlueSoulRobot%

Nah, I can't stare directly at a candle. I'm no superman. :D

Making the room darker than void black is awesome, eh? It makes me feel like I have a "power", how the darkness is so absolute. I don't see things wobbly when I look between the grains of wood though...

HoLy MaCkErEl! I see the lines! I see the lines!

Wicked....:D

Cool, you see em :D

Yeah they are very close to any object, im not sure what causes it but it might be something to do with interference patterns.

Someone said the particles are dust getting very close to the eye but I don't think that’s the case because of the way they look and move.

Those floaters are pieces that have broken of of some part of your eye. They float around in in the fluid stuff. (as you can here, I now my eye science :) :) )

But really, they're something like that.

Seeing colors around objects when staring at them: James Redfield would tell you that you can see the energy surrounding the object.

You could call it an aura.

I also heard a scientific reason for these colors. It would translate into 'afterimages', but I don't know if that means anything in English.

There are drawings at which you can stare for a few minutes, and if you look at a white wall afterwards, you can see the image on the wall: 'afterimage'.

When you look out of focus at your hand, the image of your hand floats away, cause your brain is not updating what is seen right.

I don't know why some scientific mind did not yet jump in to explain these things right.

Yeah I know about most of the things you mean, floaters are another one to add to the list but not the cause of anything I’ve described so far.

Hmm..On second thought, do you mean black lines around the fingers? Because if you do, then those are just from the fact that your eyes are defocused because of the proximity of the fingers to the face and to the screen...


heh heh heh...It looks like there are strands of glue between my fingertips, when I'm doing the "thing". :D

Hmm im not sure, it possible could be but it does look odd.

. I don't see things wobbly when I look between the grains of wood though...

That's not what I meant, I was looking at two pices of wood joined together.

Well, mart, at least you can take comfort in the fact that you're perfectly normal. :)


That's not what I meant, I was looking at two pieces of wood joined together.
Ohh, ok. :D

Yeah it’s nice to know that others can see these things. A friend said I must be very observant to even notice some of this stuff but I was also hoping to have super human vision :D

They’re almost like small atomic particles or something that streak then disappear while new ones reappear and it goes on all the time, though you won’t notice it with lots of different colours in any mess, just plain light surface.




Floaters

*** According to the health book I study......... the small particles are bits of cellular debris floating within the eye which are commonly referred to as floaters. Because these floaters cast shadows over the retina, the individual sees small specks that move slowly before the eyes, exspecially in certain lights and against certain backgrounds. Eldery and nearsighted people are most likely to complain of floaters. Most floaters eventually become less noticable and are considered benign.


Recommendation

***It is normal to see a few floaters at times, but if you suddenly see a large number of them, consult an ophthalmologist. This may be a sign of developing retinal detachment . Delaying treatment can result in a detached retina requiring lenghty surgery.








Also I noticed a strange thing when I look through my fingers or any object that has two surfaces close together I see, dark lines, almost like veins or fork lightning, which moves following the surface angle. I did think it was the dark around the light making me see the veins in my eye but that just isn’t the case as it moves following the surface, oh and to see it well you have to move your fingers or object back and forth slightly in a steady motion.








Dimness Or Loss OF Vision




Many different conditions can lead to a dimming or loss of vision. Among the most common are cataracts, glaucoma, and diabetic retinopathy. Macular degeneration and retinitis pigmentosa are less common, but do occur with some frequency. There are others as well. Retinal detactment causes a loss of vision often compared to having a curtain drawn across one's field of vision. Loss of vision may be preceded by a shower of "sparks" or lightning-like flashing of light, or by a dramatic increase in the number of black floaters in the field of vision.

Yeah, I hear you, man. :D Sometimes I'd like to be more than just a human, y'know? :)

Holey Crucifix, Lady's post is so scary! Detached retinAs?! :eek: "cataracts, glaucoma, and diabetic retinopathy..." *starts to hyperventilate*

Sparks? As in blueish small things in front of your eye at times?

lol thx for the info but as i said before the thing im explaining here is not them. I can at times see a few which is probably common and nothing to worry me about. :)

lol my eyesight is fine (im sure :confused: ) and none of that is what im trying to explain here either. Vision stays normal yet when i move an object i can see a faint outline which looks like fork lightning, branching out but following the outline of the object, it can be seen alot better when 2 objects are close together with a small gap as it merges.

Hey when I'm in a pitch dark room I see little bubbles floating if I relax my eyes. Anybody else do that?:eek:

Yes! :D Lowefly, dude, it's freaky, eh? It's supposed to be completely dark, but then there are these phantom rings/bubbles...apparitions almost, only they go away if you blink a lot or close your eyes.

Hey Mart,

It's good to see that I'm not the only one with these problems (or gifts, curses, whatever...). I know EXACTLY what you are talking about with what you are seeing, and no, they are not floaters. I can distincly tell the difference between floaters and these phosphmenes (psych terminology - documented), and these are definately not floaters. Floaters are non-voluntary and I ALWAYS see them, whereas the specks I have to WANT to perceive them. As for the brain lacking oxygen, when I focus my mind to see these specks, I have deep controlled breathing for relaxation, so lacking oxygen is certainly not causing this. I was also able to get my roomate to see them as well, you really need a mind of nothingless (think of a blank slate) and then focus on trying to percieve these things. Another note, I don't do drugs (aside from alcohol) nor have any medications, I party on weekends with friends, work hard at my studies during the week, overall, an average guy.

As for the black lines between fingers, I don't see that at all. Instead I see something that I can only explain as light 'bending' around my finger (like heat will bend light on the surface of the road on a hot day). As my finger moves across a backdrop, the images near the finger will get sucked closer to it as I move them around, much like how the sun's gravity well will change the path of light from a distant star to make the star seem like it has changed position when the sun's gravity has only altered it's course (einstein's relativity, smart bast'd).

Also, I found a similar anomaly with sound, preferrably white noise (or the sound of a fan or moving air...) when going to sleep. I found the sound would start to change from what I was hearing to something else. Some cases it would be parts of a conversation, ambient sounds you would hear on the street, pretty much anything. The only ticker was that when I had become aware the sound was no longer the sound of the static 'white noise', I would lose focus on it and I would revert hearing white noise again. To try this, simply put on some white noise or pink noise with some headphones and hit the hay. Try to clear your mind and wait... when your mind seems to drift away from this plane, you may notice strange things happening all around you.

However, I cannot perceive any of these strange occurrences randomly like I can with my floaters, I can pick those out anywhere, anytime. It's only when I focus my mind that I can see them. I think it's more of a state of consciousness than a physical problem, after all, look at what Einstein or Tesla came up with when they were able to focus the mind.

It may not be a scientific answer, but rather one of those theories that can remain a theory because there's no way of disproving it, or even proving it for that matter. Science does tell us that we do use some small percentage of our brains (~5%?), maybe concentration and focus is like working the brain muscle, allowing us to greater sensitivity or feeling to the world around us. After all, we know that there's a greater spectrum beyond visible light (ROYGBV) that we can't see, but some insects do.

I dont know i have been lookin for this issue on the net and cant find anything about it pretty rare? i dont know. anyho my issue is my eys i think. If i stare across the road say at a house? or someone that i am talking to and a vehicle passes in front of me i get a trailing effect from the car! its not massive but its grey in color like a comet trail but its like 1inch around the vehicle if its on stop its cool.

I get the same thing if i am stretching my hand out in front of me to pick something up its like a trail delay but the trail is grey in color and it allways stays close to the object within 1inch at the most its weird. I cant say i have ever suffered with this and nor does it happen 24/7 I find it does when im tired.

But i have been using computers since i was 10 and spend well in excess of 10hrs in front of the screen my vision has degraded im not blind and i do wear glasses as i can not see distant objects.

mart its just particles of dust flowing on retina of the eye

Oh dear god.. :rolleyes:

Edit: You got it Draqon :)
And dead cells etc..

There is fluid flowing around on top of your eyes which can distort the picture somewhat. Also, "mart" is correct about the lines, they are interference patterns caused when light cancels itself out.

I take it you were not referring to me?

Anyone who moves their fingers in front of the CRT based monitor will see a trailing effect. I just checked it and that happens...that is called the persistence vision. But, that is because of the refresh rate of the CRT. You should not see the same effect in day light as the sunlight does not turn off and on. Perhaps your cells are turning on and off and somehow synchronized to the CRT rate like 75 Hz. I doubt an Optometrist will understand what you are talking about. You may have to find a medical school and become a test subject.

Use a high refresh rate on the monitor like 80 or 85 HZ and see what happens. Spend 20 minutes a day blindfolded to rebalance your eyes....take some Billberries....

I see floaters too. Damn, I thought it was something more.
I can see the squigly lines that look like molecules that have been described as floaters, but if I concentrate I can see tiny dots of lights almost dancing in the sky, and these tiny dots of light appear to be much farther away then the floaters.
I thought the floaters were molecules that only I could see, but it seems I ain't so special, lmao.
I'm guessing the tiny dots of light are related to the floaters I see, although I do not know.
I have 20/20 vision, however I had laser surgery to obtain 20/20 vision. I never noticed my floaters until after laser surgey. Although I am much more aware of many things than I ever use to be, so I can not say I never had floaters before, I just never noticed. I only see floaters when I try to!

Damn, I really thought I was seeing molecules! My next eye check up, I'll mention the floaters and see what they tell me at the eye place.

PS - Sorry I'm late, I'm new here ;)

PSS - My perception on the world is quite different from the general populations percepective of the world too, but that has nothing to do with my floaters, lmao. That will be for a future discussion ;).

There is actually a name for this phenomena...seeing the little squiggly things moving in the field of vision, when looking at something bright, mainly the sky. I found it once and am having trouble finding it again, I will post it when I do.

But basically only some people actually notice it, some more than others.

Apparently you guys are able to manage the filtering mechanism of your hippocampus and hence the results...

Don't knock the filtering.

We'd all go insane without it.

These are all to do with sight and may seem strange, I have normal vision (I think) but I notice more than most seem to.

Welcome to SciForums. I am a Doctor of Optometry (eye doctor). Most of what you're describing are common examples of what's called entoptic phenomina. These are images created by the various structures within the eye itself. They generally can only be seen under certain conditions and by a person who is looking for them.

I would advise that you see your local eye doctor for a dilated exam to ensure that there is nothing physically wrong with your eyes, particularly you'd want to be checked for any evidence of a retinal tear and/or detachment
(http://en.wikipedia.org/wiki/Retinal_detachment).

Here is a nice description of entoptic phenomina:

Entoptic phenomena are visual effects whose source is within the eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake; see entopic.) In Helmholtz's words:

"Under suitable conditions light falling on the eye may render visible certain objects within the eye itself. These perceptions are called entoptical."

Entoptic images have a physical basis in the image cast upon the retina. Hence, they are different from optical illusions, which are perceptual effects that arise from interpretations of the image by the brain. Because entoptic images are caused by phenomena within the observer's own eye, they share one feature with optical illusions and hallucinations: the observer cannot share a direct and specific view of the phenomenon with others.

Helmholtz[1] comments on phenomena which could be seen easily by some observers, but could not be seen at all by others. This variance is not surprising because the specific aspects of the eye that produce these images are unique to each individual. Because of the variation between individuals, and the inability for two observers to share a nearly identical stimulus, these phenomena are unlike most visual sensations. They are also unlike most optical illusions which are produced by viewing a common stimulus. Yet, there is enough commonality between the main entoptic phenomena (see below) that their physical origin is now well-understood.

During the 1920s, some theosophists, unaware of the physical explanation, maintained that the moving spots seen in the blue field entoptic phenomenon were "vitality globules" related to the concept of prana in yoga.[2]

Some examples of entoptical effects include:
Floaters against a blue sky with cloud.
Floaters depiction
First person view of a Purkinje Tree while sitting in a slit lamp/biomicroscope
Purkinje Tree depiction

* Floaters or muscae volitantes are slowly-drifting blobs of varying size, shape, and transparency, which are particularly noticeable when viewing a bright, featureless background (such as the sky) or a point source of diffuse light very close to the eye. They are all shadow images of objects suspended just above the retina. Some may be individual red blood cells swollen due to osmotic pressure or chains of these cells stuck together and diffraction patterns can be seen around these [3]. They may also be "coagula of the proteins of the vitreous gel, to embryonic remnants, or the condensation round the walls of Cloquet’s canal" [4]. Floaters may collect over the fovea (the center of vision) and therefore be more visible when lying on your back looking upwards.
* The blue field entoptic phenomenon has the appearance of tiny bright dots moving rapidly along squiggly lines in the visual field. It is much more noticeable when viewed against a field of pure blue light and is caused by white blood cells moving in the capillaries in front of the retina. The white cells are larger than the red cells and must deform to fit. As they go through a capillary, an open space opens up in front of them and red blood cells pile up behind. This makes the dots of light appear slightly elongated with dark tails[5][6].
* Haidinger's brush is a very subtle bowtie or hourglass shaped pattern that is seen when viewing a field with a component of blue light that is plain or circularly polarized and rotating with respect to the observer's eye. If the light is all blue, it will appear as a dark shadow, if the light is full spectrum, it will appear yellow. It is due to the preferential absorption of blue polarized light by pigment molecules in the fovea [7][8].
* The Purkinje images are the reflections from the anterior and posterior surfaces of the cornea and the anterior and posterior surfaces of the lens. While these first four reflections are not entoptic, Becker [9]described how light can reflect from the posterior surface of the lens and then again from the anterior surface of the cornea to focus a second image on the retina, this one much fainter and inverted. Tscherning [10] referred to this as the sixth image (the fifth image being formed by reflections from the anterior surfaces of the lens and cornea to form an image too far in front of the retina to be visible) and noted it was much fainter and best seen with a relaxed emmetropic eye. In a dark room, with one eye closed and looking ahead with the other eye, move a light back and forth under your gaze - you should see a dimmer image moving the opposite direction.
* The Purkinje tree is an image of the retinal blood vessels in one's own eye. It can be seen by shining the beam of a small bright light penlight through the pupil from the periphery of a subject's vision. This results in an image of the light being focused on the periphery of the retina. Light from this spot then casts shadows of the blood vessels (which lie on top of the retina) onto unadapted portions of the retina. Normally the image of the retinal blood vessels is invisible because of adaptation. Unless the light moves, the image disappears within a second or so. If the light is moved at about 1 Hz, adaptation is defeated, and a clear image can be seen indefinitely. The vascular figure is often seen by patients during an ophthalmic examination when the doctor is using an ophthalmoscope. Another way in which the shadows of blood vessels may be seen is by holding a bright light against the eye lid at the corner of the eye. The light penetrates the eye and casts a shadow on the blood vessesl as described previously. The light must be jiggled to defeat adaptation. Viewing in both cases is improved in a dark room while looking at a featureless background. This topic is discussed in more detail by Helmholtz.
* Purkinje's blue arcs are associated with the activity of the nerves sending signals from where a spot of light is focussed on the retina near the fovea to the optic disk. Look at the right edge of a small red light in a dark room with your right eye (left eye closed) after dark-accommodating your eye for about 30 seconds and you should see two faint blue arcs starting at the light and heading towards the blind spot. Look at the left edge and you will see a faint blue spike going from the light to the right[11].
* A phosphene is the perception of light without light actually entering the eye, for instance caused by pressure applied to the closed eyes.

A phenomenon that could be entoptical if the eyelashes are considered to be part of the eye is seeing light diffracted through the eyelashes. The phenomenon appears as one or more light disks crossed by dark blurry lines (the shadows of the lashes) each having fringes of spectral colour. The disk shape is given by the circular aperture of the pupil.

Hi, new here, dunno how I found this place, simple site name but seems hard to find :P

Anyway it’s the best place I found to ask a few questions.

These are all to do with sight and may seem strange, I have normal vision (I think) but I notice more than most seem to.

When you look at something plain light and bright, do you see these small particles like bright streaks that move about in a random but smooth flowing way?

They’re almost like small atomic particles or something that streak then disappear while new ones reappear and it goes on all the time, though you won’t notice it with lots of different colours in any mess, just plain light surface.

Also I noticed a strange thing when I look through my fingers or any object that has two surfaces close together I see, dark lines, almost like veins or fork lightning, which moves following the surface angle. I did think it was the dark around the light making me see the veins in my eye but that just isn’t the case as it moves following the surface, oh and to see it well you have to move your fingers or object back and forth slightly in a steady motion.

Also I can see when doing the same thing, light bending slightly and sometimes red or blue shifting but that doesn’t seem possible because that’s only possible from a strong gravity.

These are some weird things I have noticed and I have to know if anyone else has noticed anything similar?

One thing you'll notice if you concentrate your vision for any particular spell is the potential for eye strain which in turn could generate some of the results you've observed. I'd also question if you have a high blood pressure, high blood pressure can effect observation. (It is possible to increase blood pressure through worrying which might be a side effect if you observe something you don't understand and perhaps worry about)

To be perfectly honest it's something that you shouldn't choose to concentrate on too deeply, unless of course it becomes too constant and interferes with your vision. At this point I'd suggest seeking medical advice from an expert.
