Have you ever wondered what those bacterialike things that you see sometimes in your visual field areé And thought that you're a super human withsenses that allow you to see micro creaturesé Well we sure did and we weren't alone. They are actually called floaters.Because. Well. They float. If you ever listened to your biology class,You would probably know that the eye is a complex structure that has many layers. The retina is the screen for your image andin front of that is a jelly like fluid called
vitreous humour. When you are young the vitreous is homogenous (fancyspeak for clear all over) But as you age. This vitreous starts toliquify. Just like gelatin. And these areas cause a shadow to be formed onthe retina. And the so called floaters are formed Although they are seen in normal eyes, floaterscan be observed extensively in some conditions like blood in the vitreous as in Diabetesor in trauma. They are also seen in people with shortsightedness,usually referred to as *quot;muscae volitantisquot;.
I know that sounds like a game of thronesreference. .but well it isn't! Why would you think it is! I just guess that it's nature's way of saying that you're getting old.
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
