I recently have had some trouble with my vision where I feel as if my eye is floating. I did have lazy eye in my left eye as a child and did have one surgery at age 2. I did not have many problems as a child, some mild headaches but vision was checked and everything was OK. I di just have an eye exam because of this problem about 3 months ago. I got contacts because I never wore my glasses. These did help for the past few months, now I get this feeling constantly. I do notice when I look in the mirror sometimes, when I get the feeling of movement that my left eyes goes upwards. As a child my eye went in. I did the patching for a while and now I know my eyes do not work together becuase of this problem. I just do not know why all of sudden agian this is happening. I can see fine it just gives me a headache when this happens. I should say that I work at a desk in front of a computer for 7 hours a day. Could this be a cause. When I am looking at the screen I do have trouble looing at it sometimes. I get a sensation by my eyes as if something were up close to my face. That is bothersome. Any recommendations would be helpful. Thank you
