First Of All I Suffer From Anxiety And General Panic

First of all I suffer from anxiety and general panic disorder. twice in the past week I have had an episode where My vision gets distorted for maybe 30 seconds. possible double vision. If I close one eye the vision is ok... if I open my eye and close the other the vision is ok. Lasted for maybe 30 seconds then goes away. Happen once about a year ago. Can this be anxiety? No other symptoms of weakness, fainting, dizzy, numbness or anything but really cranks up my anxiety.
