Hi marie, i have the same eye problems and more. I see after images of things, words, and lines, especially if they are against a light background or if its a fashing or blinking light. For example, i can see an after image of a blinking car light when i look away. I also see the halo, which is worse at night and seem to have a slight astigmatism as well. In addition, my eyes are light sensitive - i have to wear sunglasses wherever i go and fluorescent lights hurt my eyes alot. I am seeing tiny specks of light zipping across light backgrounds and developed floaters. All of my symptoms developed very suddenly. I have never had eye problems before and in fact do not even wear glasses. I have had other symptoms - anxiety, depression in the past, neck pain, numbness and tingling, tremors (hands would shake for no reason), buzzing in the ears, sometimes ear pain, sometimes a gritty sandy feeling in the eyes, bubbling feeling under the skin. I went to see a lyme literate doctor and although my bloodwork came back negative for lyme, he is treating me for it based on clinical symptoms. I have not seen much improvement in vision since being on the antibiotics but i have only started treatment. That is my story. I would be interested to know if you ever figure out the cause of your eye problems.
