Hi Sophie, I started having vision problems after I started my meds. They would get blurrly alot, always had to blink. They also seemed a little strained. At one point my vision went to like a grey color, and that was all I could see. It lasted for like 10 sec. then would be fine. I had a feeling it was from my meds, so I have stopped taking them. but I do think you can have problems with vision from Lyme.
