What are those floaty things in your eye Michael Mauser

Have you ever noticed something swimmingin your field of visioné It may look like a tiny wormor a transparent blob, and whenever you try to geta closer look, it disappears, only to reappearas soon as you shift your glance. But don't go rinsing out your eyes! What you are seeing is a common phenomenon known as a floater. The scientific name for these objectsis Muscae volitantes,

Latin for quot;flying flies,quot; and true to their name,they can be somewhat annoying. But they're not actually bugsor any kind of external objects at all. Rather, they exist inside your eyeball. Floaters may seem to be alive,since they move and change shape, but they are not alive. Floaters are tiny objectsthat cast shadows on the retina, the lightsensitive tissueat the back of your eye.

They might be bits of tissue, red blood cells, or clumps of protein. And because they're suspendedwithin the vitreous humor, the gellike liquidthat fills the inside of your eye, floaters drift alongwith your eye movements, and seem to bounce a littlewhen your eye stops. Floaters may be onlybarely distinguishable most of the time.

They become more visiblethe closer they are to the retina, just as holding your hand closerto a table with an overhead light will result in a moresharply defined shadow. And floaters are particularly noticeable when you are lookingat a uniform bright surface, like a blank computer screen, snow, or a clear sky,

where the consistency of the backgroundmakes them easier to distinguish. The brighter the light is,the more your pupil contracts. This has an effect similarto replacing a large diffuse light fixture with a single overhead light bulb, which also makesthe shadow appear clearer. There is another visual phenomenonthat looks similar to floaters but is in fact unrelated. If you've seen tiny dots of lightdarting about

when looking at a bright blue sky, you've experienced what is knownas the blue field entoptic phenomenon. In some ways,this is the opposite of seeing floaters. Here, you are not seeing shadows but little moving windowsletting light through to your retina. The windows are actually causedby white blood cells moving through the capillariesalong your retina's surface. These leukocytes can be so largethat they nearly fill a capillary

Why Do We See Stars

Hey there. I'm Josh Clark and this is BrainStuff,and this is the BrainStuff where I talk to you about seeing stars. So have you ever seen some lights appear inyour field of visioné And you were kind of certain they weren't really thereéAnd insteadof coming closer and eventually landing and kicking off a really weird experience whereyou ended up abducted and probed and then dumped in the woods. that didn't happené And instead these lights went away, they wereprobably phantomsé Well then you, my friend, saw what are called 'phosphenes.'

Phosphenes are lights that aren't really there.They're the result of your visual system being fooled in some shape or fashion. And yourvisual system itself consists of about three main parts. You've got your retina, which are the lightsensitive cells in the back of your eye that pick up photons from the environment. You've got the optic nerve, that takes theelectrochemical signal that your retina translates the photons into, and carries it up to yourbrain. Then you've got the occipital lobe, whichis the first initial sorting center for visual

stimulation. You put all these things together and somethinggoes from, quot;I see a blob of color,quot; to quot;I see pizza!quot; So phosphenes again, these phantom lights can be produced any time any part of your visual system is manipulated. And there'stwo main ways they can be manipulated: mechanical and electrical. Electrical stimulation is basically where,say, you take an electromagnet and run it past your occipital lobe you can producephosphenes. It's also been shown to produce

phosphenes when you take electrodes and implantthem near your optic nerve. You can actually produce phosphenes in people who are blindbecause of a retinal malfunction. That means that the rest of their visual system is working,and if you stimulate it electrically, you can produce these phantom lights. Which ispretty awesome. There's also mechanical stimulation, whichis like when your rub your eyes like Tom or Jerry. You can also produce it when you pressthe side of your eye very gently and slowly toward your nose. It will eventually producephosphenes. You can go ahead and do it just do it gently.

Mechanical stimulation can also be inducedin the occipital lobe itself, specifically if somebody hits you over the back of yourhead with a guitar and your brain slaps around your skull in that area. The neurons, stimulatedsuddenly, are fooled into thinking that they are sensing something, and maybe getting anelectrochemical signal from the optic nerve. You can also see stars from things like sneezing,which is pressure induced, kind of like pressing on your eye. There's also something that hasto do with blood pressure, although it's not quite clear why. Where if you stand up quickly,you feel a little faint and you start to see starsé It's probably from a change in theoxygen available to either your retinal cells,

optic nerve, or your neurons. And there's other ways phosphenes can be producedtoo, like, for example, drugs. Or if you lack any kind of visual stimulation, like you'rea long distance trucker or a pilot flying at night. You can start to hallucinate phosphenes. So should you be worried if you see starséWell, if you've just been pressing your eye or you just sneezed and the stars come andgo pretty quickly, probably not. But if somebody did hit you over the backof the head and you're seeing stars, you should probably go to the ER, because you may havejust suffered a concussion.
