Hello, I am not a doctor but in my opinion if you are having any changes to your vision or symptoms please do see an eye md (ophthalmologist). It probably is nothing but you will worry about it needlessly until you do. If you have never had your eyes examined thoroughly by an eye md, perhaps now would be a good time to start anyway.....get a baseline on things and start annual checkups. I put it off too long and a simple laser repair to fix a tear in my retina resulted in a much more invasive surgery to fix. Good luck, Jim
