Some people suffer from a
hereditary eye condition known as Retinitis Pigmentosa. It makes them debilitating
near-sighted and requires them to use a blind cane at night or in dark spaces. The
unique technical design of a VR headset can provide the illusion of depth
through special lenses, but in physical reality the screens they are employing
are mere centimetres away from a user’s face.
This, coupled with the
dual-screen projection method of the Vive — in which every single image a user
sees is actually two images relayed to separate screens in front of each
eyeball — can end up being the perfect storm of factors to judo-flip user’s
typical visual impairments and render their vision closer to normal than they
had experienced in decades.
