Abstract

A method for ordering a corrective clip having corrective lenses. The clip corrects a wearer's view of a head mounted video display. When customers purchase an HMD, they are provided with clip ordering information. This includes information allowing the users to determine if a clip is required for their personal use. By providing at least SV and PD data customers can place their own orders which are transmitted to the lab. The completed corrective clip is delivered directly to the customer. Since the clip mounts on the viewer, a fitting session is not required. In use, the corrective clip reside between the user's eyes and an HMD display, without contacting the user.
