In some implementations, the clip-on accessory includes an oval or a rounded opening centered in a frontal portion of the clip-on accessory. In some implementations, the clip-on accessory includes attachment arms with particular curvatures and various lengths to enable attachment to see-through head-mounted devices of various sizes, as illustrated in FIGS. 9 and 18 . In some implementations, sections of the clip-on accessory that are configured to cover eyepieces of the head-mounted devices, to which it attaches, are made of opaque material, semi-transparent material (e.g., to block or enable transmission of a particular wavelength), or substantially transparent material.
