Hi im a man 29 yo from flanders belgium

When i turn my head clockwise towards my right shoulder my right eye's vision jumps xtremely fast when on a certain degree of 45 and focusing at a certain point.
And then it settles.

I first noticed this about 10 month ago or so .. in the evening when watching television. i was creeped out by this.

my left eye does this also when turning to the left counterclockwise. in any other direction nothing happens. I cannot find anything about this on the internet.

When i move my eyes the same direction of the turning nothing realy happens. It only occurs when focusing at 1 point.

Thanks in advance,
