The Useful Field of View (UFOV)


The UFOV – first introduced in 1993 through an article in the Journal of the American Optometric Association, has received more attention lately in the context of driving safety for senior citizens.  It is clear that our traditional clinical tests don’t do a very good job in addressing increased visual risk factors for driving mishaps.  Optometrists engaged in vision therapy have become increasingly involved with tests and measures involving UFOV and Visual Processing Speed in a wide range of populations, including children.  UFOV can be conveniently conceived as a combination of visual field measurement coupled with peripheral awareness – in other words, how objects are processed within the window of attention rather than just points of light.
