What are these unusual floating objects that appear in our line of sight?

Where does this vision of strange floating bodies come from?

These floating bodies, which have shapes of filament or small balls, may make people think of bacteria. But these forms are actually shadows of compounds of the glass mood. These floating bodies have a name: myodesopsies.

These are proteins in the shape of filaments that are found in the vitreous mood, this transparent and gelatinous substance that makes up 80 % of the eyeball and which is between the lens and the retina. Observing these myodesopsies is a very natural and harmless phenomenon. These proteins affect around 70 % of the world's population. Myosedopsies will project their shadows on the retina during the passage of light. To be able to observe them, you have to look at a light source like the sky or a lamp.

Myodeopsies: an increase with age

As said before, this phenomenon is completely natural and affects a large part of the population. However, these myosedopsia increase considerably with age. The glass mood is retracted throughout life, this will cause the appearance of micro-debris. A sudden increase in the phenomenon can be linked to the appearance of hemorrhage, a tear of the retina or even an eye infection. In this case an operation is necessary.
