Have you ever looked up at the sky and seen worm-like things floating in your eyes?
Yes, it’s like worms, worms or other weird shapes… but in the end, when you’re trying to look at it, it moves and returns to its original position when your eyes return to its original position, so so you will feel it moving in your eyes.
What you see is a phenomenon called “ephemeral”, whose scientific name is Muscae volitantes, in Latin it means “flying fly”, maybe they find this ephemeral phenomenon very unpleasant like flies are flying in front.
In fact, Muscae volitantes are not animals floating in your eye, but rather tiny objects that are floating and when light passes through, it also casts shadows on the retina of your eye.
In your eye there is vitreous fluid, which is like a gel to fill the eye, what floats is usually a piece of tissue, red blood cells or some protein in the vitreous.
Since they float with the eye movement, they move slightly when the eye stops.
These are very subtle, we can only see them when they are close to the retina.
You just imagine there is a light bulb (light source) shining straight down on a table (retina), and your hand (things floating in the eye) is hovering between the table top and the bulb…
At this time, when your hand is close to the table, the shadow of your hand will appear clearly on the table, and when your hand is near the light bulb, the black shadow on the table will be very dim.
To be able to see these easily, you should look at bright and uniform scenes such as the sky, blank screen, etc. With color uniformity and few objects appearing, it will be easy to see. these floating things.
There is another phenomenon that looks similar to Muscae volitantes, but is actually unrelated.
That’s when you look up at the sky and see small spots of light that are constantly moving, a phenomenon called “flashes”.
With this phenomenon you can understand as follows, in your eyes there are capillaries to conduct blood and to facilitate the passage of light, these capillaries are transparent.
The white spots you see are white blood cells moving inside these capillaries, the size of the white blood cells is quite large so often the red blood cells will be bunched up behind, in some convenient cases, you even This red blood cell can even be seen because it is the dark streaks behind the path of the white blood cells.
In the eyes of most of us, these phenomena occur.
The phenomenon of floating ephemeral we usually won’t notice it too much because in the course of evolution, our brains have ignored it to focus on more real things.
However, in some cases, with the size of the objects being quite large and making you feel uncomfortable, you should go to the hospital for treatment.
