I don't know this because I have been short-sighted for as long as I have the ability to remember.
Answer:
Sorry Xerxes but if you turn your eye in either direction without moving your head, the fovea centeralis moves with the eyeball and the result is no matter how much you turn your eyes AS LONG as that fovea in in line with the object viewed it is sharp and clear.
Of course if you’re looking through your glasses, it is quite likely that the extreme periphery or edge of the lens might not be as clear as the center of the lens but with the precision optical manufacturing devices this day the edge of lenses are extremely accurate.
Theoretically, if you stared straight ahead and put a book 40 or 50 degrees away from straight on and THEN turned your eyes that 50 degrees you could still read the book.
I think that is the question the asked wanted to know.
Even as we speak here I’ve placed a letter far off to the left as I type. Now without any movement of my head but only turning my eyes far left I am reading that letter perfectly.
I think you meant that too but some how it got blended up in the wording or you would not have stated NO to the asker.
Hope I didn't offend Xerxes or anyone else.
Answer:
No. In fact even you can't see clearly through all points of your glasses at any given moment.
As I'm sure you know, visual scenes are first taken in by the retina, on the back your eye. There's a spot on the retina called the fovea. The fovea accounts for about 2% of the total space of the retina, but has about 98% of the photoreceptors (rods and cones). Anything outside of the angle of acuity of the fovea is much less distinct.
Basically, you can only see something clearly if you're staring right at it.
