Perhaps they could do like what is done when using certain types of medical equipment and ave the part that is in contact with the person wearing it switched out between each use.

The problem is that the body and lenses of the VR set are also likely to come into contact with your face/eyes. This is amplified by the fact that the lenses are really optimized to be right against your eyes. As you go farther and farther out, the field of view gets narrower and the picture gets softer. So most VR users will prefer to play with them cranked in as far as they can go (while still fitting eye-glasses, etc). The "thin"/"wide-FoV" VR covers I posted above actually put you even closer than would normally be possible. Disposable pads would probably be nice in a commercial setting like a theater, but you would also really need to spray down the body and lenses of the headset with a sanitizer because some contact with the lenses is nearly inevitable. AFAIK this is similar to how 3D glasses are processed for reuse. I would just like to note that it is an extremely difficult optical problem to get what amounts to a smartphone a half inch from your face with no screen curvature to present an image that covers your field of view adequately, focused at optical infinity, at a relatively constant magnification factor (pixels are the same size), and without such excessive levels of distortion that the rendering cannot be corrected in software. The closest analogy is really the old superwide Nikon lenses that needed to have the mirror flipped up so they could go deep into the camera and perform corrections right up to the film plane. Really it's a testament to modern manufacturing and lens design that this is possible at any sort of a price that would be reasonable for consumers to own. Molded plastic lenses with aspheric surfaces are amazing compared to what you could do with regular spherical glass surfaces. http://www.mir.com.my/rb/photography/companies/nikon/nikkoresources/6070nikkor/fisheyes/75mm56.htm http://www.mir.com.my/rb/photography/companies/nikon/nikkore...
