An optical system includes an optical system axis, a display, and at least one lens, the optical system forming a virtual image of an image emitted by the display for viewing by an eye having an optical eye axis, such that a first retinal image of the virtual image at a first virtual image position and an associated first angle of view has a first image resolution when the eye axis is substantially coincident with the system axis, the first angle of view being between about 5 degrees and about 30 degrees, and the first retinal image has a second image resolution when the eye rotates such that the eye axis substantially coincides with a first field axis extending at the first field angle between the eye and the virtual image, wherein the second image resolution is greater than the first image resolution. 一种光学系统包括光学系统轴线、显示器和至少一个透镜，该光学系统形成由该显示器发射的图像的虚像以供眼睛观看，该眼睛具有光学眼睛轴线，使得该虚像的在第一虚像位置和相关联的第一视场角处的第一视网膜图像在该眼睛轴线与该系统轴线大致重合时具有第一图像分辨率，该第一视场角在约5度和约30度之间，并且该第一视网膜图像在该眼睛旋转以致于该眼睛轴线与以该第一视场角延伸在该眼睛和该虚像之间延伸的第一视场轴线大致重合时具有第二图像分辨率
