Since April I have experienced when I look left or right and sometimes up and down its as if smoke runs across my eyes. I have also experienced blurry vision, and floaters. I reccently went to the eye doctor and he took a look at my eye with a light and said everything looked fine and didn't seem concerned even though my vision has gotten 3 points worse since my last exam 10 months ago. Also this all started right after I found a spider on my head I got a real bad headache and then a week later I started having problems with my eyes that have continued to get worse. What could be wrong? Should I seek a second opinion?
