The vitreous jelly naturally undergoes some liquefaction, resulting in small pockets of more liquid vitreous lying within the firmer gel. This is called vitreous syneresis. The boundary between each liquid pocket and the gel may be noticeable to the person as one or more eye floaters. In addition, it normal for the collagen fibers that are within the vitreous to become thickened and denser with age, resulting in eye floaters. Any person who is over 50 will have these changes within their eyes. However, the degree of eye floaters produced by these typical changes will vary from person to person.

This shrinkage often leads to the back surface of the vitreous moving forward within that space. The vi
