Hi Phil
It is an optical issue unfortunately, the FOV is so massive that the very edges - at the extremes - tend to suffer a little distortion. Something to do with the laws of optics and eye position, TBH I forget about it as I tend to use the edges only to detect movement and the distortion is such a small % in that it's seldom noticable and never affects function
