Claim:
1. A hybrid optical system for a head wearable display, comprising: a central vision lens to approximately align with a cornea of a user and to provide lensing to a central vision of the user when the user is looking straight forward; and a peripheral vision lens, different than the central vision lens, to provide lensing having optical power to an extended field of view (“FOV”) that extends angularly beyond the central vision lensed by the central vision lens when the user is looking straight forward, wherein the peripheral vision lens is disposed around the central vision lens, wherein the peripheral vision lens has a co-incident optical center with the central vision lens but the central vision lens is offset from a physical center of the peripheral vision lens, wherein the central vision lens comprises a refractive lens having two opposing sides that are both curved surfaces and the two opposing sides along with the peripheral vision lens are molded into a single piece of plastic.
