Floaters can damage the retina by tugging on it, sometimes producing a tear. If that happens, you have very little time to get it fixed before it effectively dies and you go blind from that eye. There is a chance (1 in 7) that your retina is about to detach from the back of your eye. If you ever see a ton of floaters appear out of no where, possibly with some light flashes, you should get to an eye doctor immediately. Entoptic phenomena are things we see where the source is within the eye itself. Eye floaters are examples of entoptic phenomena. So as you try to look at them, they will appear to drift with your eye movement. The reason the floating specs never seem to stay still is because floaters, being suspended in the vitreous humor, move when your eye moves. The perception of eye floaters is known as myodesopsia. Individual floaters often won’t change much throughout your lifetime, typically retaining their basic shape and size. The reason you can see floaters better when looking at, for instance, a bright blue sky, is because your pupils contract to a very small size, thus reducing the aperture, which in turn makes floaters more apparent and focused. One example of this inside your eye are blood vessels in the eye which obstruct light because they are fixed in location, relative to the retina, your brain tunes them out completely and you don’t consciously perceive them. Your brain does this all the time with things both in and outside of your eyes. Interestingly, if the eye floaters would just stay still instead of floating around, your brain would automatically tune them out and you’d never consciously see them.

These floaters are microscopic in size and only appear as big as they do because of their proximity to the retina. Instead, they are found in the Premacular Bursa area, right on top of the retina. These floaters aren’t found in the vitreous humor like the above floaters. However, they do still sometimes experience a certain type of eye floater that often appears more like a crystallized web across their vision. This shadow is actually what you are seeing when you see the eye floaters.Ĭhildren and teenagers almost never experience these types of eye floaters as there must first be some deterioration of the gel-like substance in their eye, creating the watery core, for these floaters to appear. When light passes through this area, it creates a shadow on your retina. When this happens, it forms a watery core in your vitreous body.Īs you age then, pieces of the still gel-like collagen/hyaluronic acid network will break off and float around in this watery center. Over time though, this network breaks down which results in the hyaluronic acid releasing its trapped water molecules. Hyaluronic acid ends up retaining water molecules. This gel is about 99% water and 1% other elements the latter of which consists mostly of a network of hyaluronic acid and collagen. The vitreous humor, or often just “vitreous”, is a clear gel that fills the gap between your retina and lens, helping maintain the round shape of your eye in the process. There are a few different things that can cause this, but in most cases these eye floaters are caused by pieces of the gel-like vitreous breaking off from the back portion of your eye and then floating about in your eye ball. 
These are not optical illusions, but rather something your eyes are actually perceiving. Their shapes vary greatly, but will often appear as spots, cobwebs, or randomly shaped stringy objects. Today I found out what causes “eye floaters”.įor those who’ve never experienced this phenomenon, eye floaters are little oddly shaped objects that appear in your vision, often when one looks at bright light such as a blue sky.
