Tried both tennisparent and jtreed's suggestions. JTReed is correct - the eye that is OPEN when the object does NOT appear to move is dominant.
And what a startling result! My right eye is way more dominant, with or without glasses. I am right handed so that theory does not apply to me.
And I have astigmatism too.
If right eye is dominant and I am a right-hander, I assume forehands will be easier for me than backhands, correct? That is the case with me. I just don't see the ball well on the BH even with a good shoulder turn. I have a good excuse now.
Are there any exercises to make the non-dominant eye more dominant?
