Thanks stealthycat. I was also told to cover one eye with a patch. Will this help. The problem I have is when I have both eyes open I see 2 targets. I don't really know how to tell because when I do the eye tests for dominance, I do the put your hands in a triangle and aim at something and pull back. Which ever eye you touch is your dominant eye. test. I end up seeing 2 sets of hands. I just don't know.
