See Opthalmologist: Any loss or change in your vision can indicate that something serious is going on. You should see an Opthalmologist which is an MD specifically trained in eye diseases. They can do an in depth exam of all the components of your eye to determine what is going on. You should be sure not to drive until you have been treated, as depth perception can be affected and cause you to have an accident.
