Hi, I have been taking 50 mg seratalin for the past few months. Particularly when I read news or books in my iphone, I find it hard to discern the letters like if you shake the book when you read. It is not really blurred. and I need high contrast for me to be able to read comfortably. I never had this problem before this medication. It did not start straight away. It took several weeks before I noticed. What I need to know is that will my eye sight go bad gradually or it will just stop at that side effect? Thank you Mani
