Hybrid reflective/refractive head mounted display

A hybrid reflective/refractive head mounted display, comprising:

• a structural frame;
• a plurality of refractive optical lens elements;
• first and second optics housings coupled to the structural frame and respectively positioned at least partially in front of a user's first eye and a user's second eye;
• first and second light-emitting visual sources respectively contained in the first and second optics housings;
• first and second plurality of reflective optical surfaces respectively contained in the first and second optics housings, at least one of each of the first and second plurality of reflective optical surfaces is a concave or convex reflective optical surface;
• wherein visual content is transmitted from the first and second light-emitting visual sources to the first and second plurality of reflective optical surfaces, the visual content is reflected within the plurality of first and second reflective optical surfaces at least four times without passing through a refractive optical lens element, and the visual content is transmitted to the user's first eye or the user's second eye;
• wherein, simultaneous with the transmission of the visual content to the user's first eye or the user's second eye, a real-world view of the outside surrounding environment is transmitted to the user's first eye or the user's second eye;
• wherein the visual content is overlaid onto the real-world view of the outside surrounding environment.
