Abstract
In some embodiments, a head-mounted display device includes an optics block and a varifocal actuation system coupled to the optics block.

In some embodiments, the tandem retaining configuration includes a hooking structure or a washer-based structure, the tandem guidance system includes an anti-creep system, and the tandem preload configuration includes a preload magnet and a preload target.
