What is ‘flying eyes’? Does flying eyes affect eyes? Muscae Volitantes

Have you ever noticed something swimming in your field of vision? It may look like a tiny worm or a blob, and whenever you try to get a closer look, it disappears, only to reappear as soon as you shift your glance. But don’t go rinsing out your eyes! These are called eye floaters or flying eyes.

Eye Floaters

What you are seeing is a common phenomenon known as a floater. The scientific name for these objects is Muscae Volitantes, Latin for “flying eyes,” and true to their name, they can be somewhat annoying. But they aren’t actually bugs or any kind of external objects at all. Rather, they exist inside your eyeballs. Floaters may seem to be alive, since they move and change shape, but they are not alive. 

Floaters are tiny objects that cast shadows on the retina, the light-sensitive tissue at the back of your eye. They might be bits of tissue, red blood cells, or clumps of protein. Suspended in the vitreous humor, the gel-like liquid in your eye, floaters drift with movements and bounce when your eye stops.

Have you ever noticed tiny floating shapes in your vision? These are called eye floaters or flying eyes (muscae volitantes), and they can affect your overall vision health.

3S which causes eye floaters. 

Floaters may be only barely distinguishable most of the time. They become more visible as they are nearer to the retina, like a hand casting a sharper shadow under overhead light. Floaters stand out on uniform bright surfaces like a computer screen, snow, or clear sky, where backgrounds are consistent. The brighter the light is, the more your pupil contracts. This mimics replacing a diffuse light with a single bulb, which makes the shadow appear sharper.

Another Phenomenon 

Another visual phenomenon looks like floaters but is unrelated. Tiny dots of light in blue sky are the blue field entoptic phenomenon. In some ways this is the opposite of seeing floaters. Here you are not seeing shadows but little moving windows letting light through to your retina. 

The windows are actually caused by white blood cells moving through the capillaries along your retina’s surface. These leukocytes can be so large that they nearly fill a capillary causing a plasma space to open up in front of them. Because the space and the white blood cells are both more transparent to blue light than the red blood cells normally present in capillaries, we see a moving dot of light wherever this happens, following the paths of your capillaries and moving in time with your pulse.

Under ideal viewing conditions, you might even see what looks like a dark tail following the dot. There are the red blood cells that have bunched up behind the leukocyte. Some science museums have an exhibit which consists of a screen of blue light, allowing you to see these blue sky sprites much more clear than you normally would. 

Conclusion

While everybody’s eyes experience these sort of effects, the number and type vary greatly. In the case of floaters, they often go unnoticed as our brain learns to ignore them. But too many or very large floaters that affect vision may signal a serious condition needing quick medical care. But the majority of time entoptic phenomenon, such as floaters and blue sky sprites, are just a gentle reminder that what we think we see depends just as much on our biology and minds as it does on the external world. However, if eye floaters suddenly increase in number or interfere with your vision, you should consult an eye specialist, as protecting your eyes is essential for long-term health.
