I have always had good vision, never had a problem reading small text from far distances or anything like that.. but today I noticed that when I close my right eye and try to read text with only my left, it is blurry and kind of goes in and out of focus but gets better when I move closer, everything is normal with my right eye. Has anyone ever experienced this? could it just be something temporary? I didn't poke my eye or anything, it doesn't hurt and i'm not getting any headaches or anything from it.
