My Dad Is A Truck Driver With Type 2 Diabetes.

My dad is a truck driver with type 2 diabetes. He mentioned to me that yesterday morning he has been having trouble with his vision. He described the symptom as a double vision and only able to see correct with one eye open. He also mentioned that he has been skipping meals or having trouble finding a place to eat at his eating hours. Is there something he can do to improve his vision?
