Re: Tunnel vision babbu5508 - 08-30-10 03:16 My answer is: a.
Tunnel vision can be caused by:
Blood loss (hypovolemia)
Alcohol consumption causes tunnel vision [2]. In addition, the vision becomes blurred or double since eye muscles lose their precision causing them to be unable to focus on the same object.
Retinitis pigmentosa, a disease of the eye.
Sustained (1 second or more) high accelerations
