It : It is difficult to tell you exactly, but trauma to the head can injury your cranial nerves. Some people are born with weak 4th cranial nerve that can be worsened after head trauma.

Possible CN 4 palsy: You may have a partial cranial nerve four palsy which causes superior oblique weakness and resultant double vision. See an eye doctor.

Double vision: Many conditions can cause double vision, some of them can be related to a car accident. A bad injury can affect one of the nerves that controls vertical eye movement. This is common after an orbital bone fracture. There are also some medical conditions that cause double vision. Some of these are neurological, some are related to high blood pressure or diabetes. Hard to make a diagnosis here.
