I am worried about my deteriorating vision. Am tapering between 3 and 4 mgs successfully but am getting double vision ( very noticeable when driving) and blurred vision at times. As a graphic designer, looking at a screen all day with this is frustrating. Changed my optician who told me I had variable vision and slight cataract or something and gave me herbal pills for the floaters. Not worked. Is this pred effect and will my normal vision return when off it?
