FutureVision™ is a "glass eyeball" sold at The Astronomy Tower. The device costs sixteen Lions (or $320 Muggle), and allows the wearer to see what a person will look like as they age. Using such an eyeball, David Washington saw that Dylan Weitzner is "gonna go bald." When he looked at Alexandra Quick, however, she "only got a little older" due to the fact that, several months prior, Quick had struck a deal with the Generous Ones that gave her only seven years to live.
