Abstract

Head-mounted display (HMD) technologies are improving in resolution and brightness, but are not generally solving three key issues of prescription, accommodation and presbyopia. Eyeglasses worn within head-mounted devices reduce their optical quality, eyetracking efficacy, and comfort, they add stray light/reflections and increase bulk. Fixed inserts are more compact, but require many stock keeping units (SKU's), are incompatible with shareability, and have achieved a low market share. Adjustable lenses present a low SKU, integrated, on-demand solution to these issues, but with some remaining technology challenges. We show how the spherical optics adjustable non-round fluid-filled lens may be extended to general ophthalmic prescriptions by the inclusion of astigmatism correction on an arbitrary axis. We also describe methods to produce the long lifetime fluid-filled lens with an anti-reflective surface. Finally, we define the rules for building a minimal thickness and weight liquid lens.
