A head mounted display (HMD) incorporates lenses that operate as pass-through optics for most wavelengths, but for incident light at certain wavelength(s), the lenses operate to effectively magnify such light. As such, when a user wearing the HMD device looks at a display device configured to display certain content using light having the specified wavelength, the displayed content is magnified and superimposed on the rest of the scene in the field of view. As such, the HMD device enables smaller screens to effectively present as much larger screens to the user, without requiring optics that magnify everything within the field of view indiscriminately.
