There are things they can do and just living with it by squinting, covering an eye, can even create more strain on your eyes. If it is a muscle affecting your vision, there is a surgery they can do to correct it, and they can also add prisms to your glasses [whether it be Rx glasses or reading glasses], and there is probably more things they can do. This is just what I have learned from my experiences. I'm not trying to be a "know it all", just offering up some info. Mine cannot be helped because I have so many other eye conditions, but trust me, if there were something I could do about it, I woould. I have lived with this too many years. Hope this helps!
