Abstract
An optical see-through (OST) near-eye display (NED) system is presented, integrating ophthalmic correction for an eye of a user, comprising a partially transmissive partially reflective lens, including an inner surface characterized by an inner surface radius of curvature exhibiting a first optical power, and an outer surface characterized by an outer surface radius of curvature exhibiting a second optical power, said partially transmissive partially reflective lens is configured to be facing said eye, and to at least partially transmit incoming light of an outward scene to said eye; and an electro-optical unit, configured to be optically coupled with said partially transmissive partially reflective lens, and including a light display configured to project a light beam image onto said inner surface, so to enable reflection of said light beam image toward said eye, said electro-optical unit is configured to be located at a glabellar region of said user.
