I've had diplopia (double vision) since at least last summer.

When I look to the right without moving my head, or if I try to look back towards the right when I'm backing my car out of a space, I get the double vision.

It's a bit irritating at times, but I've adjusted to it. The double image on the right is always the correct image for me, and I've pretty much trained my eye to not look too far to the right, I tend to turn my head more instead now.

Some days are worse than others. When I had ON earlier this spring, it was a lot more noticeable.

You should probably go visit your opthalmologist to make sure there's nothing else wacky going on in your eyes. He might be able to get you a new glasses Rx with a prism in it to correct the diplopia.
