Can head injury cause floaters?

Not by definition. The common term "floater" refers to defects in the gelatinous substance contained in the eye ; occurs due to aging . Floaters have not been described as secondary to head injury. This is not to say that something could not be forcefully detached or traumatized inside the eye after a head injury giving a visual perception of a problem but it wouldn't be called a "floater.".
