Never heard of the blurred vision but from things I have read it seems it could be possible. Are you going to keep your root canaled tooth or get rid of it? I have a problem one and have not decided yet. My tooth does not hurt but underneath it does in chin area. Probably bone infection. I been on antibotic's on and off for 18 months now and thinking maybe I should get rid of mine and be done with it but hate to lose a tooth but hate being upset over it all the time also......
