A head mounted display system (60, 250) configured to project light to an eye of a user to display augmented reality image content in a vision field of said user, said head-mounted display system comprising: a frame configured to be supported on a head of the user; an eyepiece disposed on the frame, at least a portion of said eyepiece being transparent and disposed at a location in front of the eye of the user when the user wears said head-mounted display such that said transparent portion transmits light from the environment in front of the user to the eye of the user to provide a view of the environment in front of the user; at least one occluder comprising a spatial light modulator configured to receive electrical input to cause one or more pixels of the spatial light modulator to be transmissive while other pixels of the spatial light modulator are opaque, wherein said eyepiece comprises a transparent emissive display comprising a plurality of emitters; and wherein the transparent emissive display is configured to emit light into said eye of the user to display augmented reality image content to the user's vision field, said transparent emissive display being transparent and emissive over an area, said transparent emissive display disposed at a location in front of the eye of the user when the user wears said head-mounted display such that said transparent emissive display transmits light from the environment in front of the user through said transparent emissive area to the eye of the user to provide a view of the environment in front of the user, characterized in that, the head-mounted display system further comprises a proximal lens and a distal lens disposed in an optical path between the transparent emissive display and the environment, wherein the at least one occluder is between the proximal lens and the distal lens; wherein the proximal lens and the distal lens are configured to form an afocal lens pair, and wherein the at least one occluder and the proximal lens are separated from each other by the focal length of the proximal lens. a frame configured to be supported on a head of the user; an eyepiece disposed on the frame, at least a portion of said eyepiece being transparent and disposed at a location in front of the eye of the user when the user wears said head-mounted display such that said transparent portion transmits light from the environment in front of the user to the eye of the user to provide a view of the environment in front of the user; at least one occluder comprising a spatial light modulator configured to receive electrical input to cause one or more pixels of the spatial light modulator to be transmissive while other pixels of the spatial light modulator are opaque, wherein said eyepiece comprises a transparent emissive display comprising a plurality of emitters; and wherein the transparent emissive display is configured to emit light into said eye of the user to display augmented reality image content to the user's vision field, said transparent emissive display being transparent and emissive over an area, said transparent emissive display disposed at a location in front of the eye of the user when the user wears said head-mounted display such that said transparent emissive display transmits light from the environment in front of the user through said transparent emissive area to the eye of the user to provide a view of the environment in front of the user,
