This page is meant to list HMDs that can be purchased. Most of these HMDs could serve as an alternative to building your own, however as most of them are opaque masks that cover both eyes and do not incorporate cameras, they are generally unsuitable for Augmented Reality. Note: This list is incomplete. If you are considering purchasing an HMD, please also look at the pages in the Links section and do your own search for other brands of HMD. Please also add/link to products if you find any others.
