Get the fit overs and stop all this foolish fussing about nothing will ya? Yer wasting valuable

Well, it's
possible, but that means cutting the lens to have the optical center way out towards the side. Looking straight ahead, however, would be just plain blurry (and, for us high-refractive types, with nice rainbow colors, too).
[trivial tangent]Firearms hobbyists get shooting glasses cut with the optical center raised higher than normal so that they can see the gunsight more clearly; in boot camp, we raised our issued glasses with a foam earplug and a piece of tape to get the same result. [/trivial tangent]
