She reached up and found the lever on her varp that activated an opaque screen over the lenses: essentially, a blindfold. Her view of the cabin was now blocked. The only things she could see were those being projected into her eyes by the varp. At the same time she activated an application that gave her the ability to see the flivver’s surroundings as if she were floating adrift in space. The same service could have been provided by a bubble of glass on the flivver’s hull, but it wouldn’t have been as good. It would have exposed the user’s head to cosmic radiation, and the contrasty light would have made it difficult to see certain things. The varp, on the other hand, played games with the light’s dynamic range so that bright things were less so while dim things were bright enough to see; it gave everything a luminous warm quality that did not exist in reality. It was so far superior to looking at the world directly that many space suits eschewed transparencies altogether and just encased the wearer’s head in a radiation-shielded dome with a varp on the inside.
