Eyesight problems and pins and needles in had? :S?

PinkFairy I get these as well specifically flashing lights and floaters and sometimes sensitivity. I have to ask do you wear contacts? I feel my contacts cause this for me. Now on to the problem. Its probably nothing. If it is something, the range of things it could be is somewhat great. I read that if you wear contacts you can get fungus buildup in the eyes that can cause these symptoms. Again i am having these symptoms also and think its nothing. I am wondering to myself if it could mean too much time spent looking at tv or a computer.
