i had a eye examine in sept. got a new prescription because a change in right eye, left eye was same. 2 weeks later started having a blurr in left eye that feels like something in it. went back to eye doctor he said he thought it was a floater or cobweb , well its worst ,sometimes it pulsates with my heartbeat , it moves and is causing me trouble seeing period. what else could it be, a second opinion would be helpful because he didnt seem to understand.
