Have your ever seen this floating thing on your vision? It look likes a worm shape but in blur and i have seen this biggest mystery of my life. Is it an eyes defect? Actually the eye floaters are little oddly shaped objects that appear in your vision, often when one looks at bright light such as a blue sky. The reason why this mysterious floating on our vision is because of 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.
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. This gel is about 99% water and 1% other elements; the latter of which consists mostly of a network of hyaluronic acid and collagen. Hyaluronic acid ends up retaining water molecules. Over time though, this network breaks down which results in the hyaluronic acid releasing its trapped water molecules. When this happens, it forms a watery core in your vitreous body.
As you age then, pieces of the still gel-like collagen/hyaluronic acid network will break off and float around in this watery center. When light passes through this area, it creates a shadow on your retina. This shadow is actually what you are seeing when you see the eye floaters. Other optometrists assume this problem is a normal thing not a defect. The perception of eye floaters is known as myodesopsia (myopia actually refer to nearsightedness) mean people of having this defect have a much higher chance of experiencing vitreous detachment due to their often elongated eyes shape and eye floaters are examples of entoptic phenomena. Entoptic phenomena are things we see where the source is within the eye itself. So, surgeries do exist for getting rid of eye floaters, if they seriously hamper your vision. This is typically done by replacing the gel-like substance in your eye with a saline liquid.
