Abstract
The disclosure describes artificial reality (AR) systems and techniques that enable a change in focus of virtual image content without substantially changing magnification of real-world content. For example, an AR system includes a virtual image content output device, a first tunable lens on a real-world side of the virtual image content output device, a second tunable lens on an eye side of the virtual image content output device, and at least one compensating lens. The at least one compensating lens is configured to substantially eliminate magnification changes of real-world light between a real-world end of the optical system and an eye-side end of the optical system as a focal power of at least one of the first tunable lens or the second tunable lens changes.
