I had the nicotine patch on all day...had no problems....took it off at 10pm...them maybe 45 minutes later my eyes got real blurry...couldn't read my Facebook comments or text's on my new touch screen phone. Could a touch screen phone do that to your eyes or most likely was it the patch. Don't understand...had it on all day...it was only after I had it off for awhile that my eyes got real blurry. I could see everything else alright but not when I had to read something. I've used the patch in the past a few times n had no problems. My vision has cleared up some but when I look at my touch tone phone at my texts my eyes are still blurry but yet now I can read my Facebook comments.
