Decentred lenses have been used for decades. They were developed by still and video camera lens manufacturers in the 80s. All high curve / wrap around sunglasses should use decentred lenses to move the optical centre of the lens in front of your eye where you need it. This reduces distortions in the periphery to below the limits of the eye. A high wrap lens that is not decentred, would give you a seasickness type effect.
