Simulated low vision
Low vision comes in many forms, involving combinations of loss of acuity, contrast sensitivity, and visual field. This is an example of a “normal” office scene (the Perception and Graphics Laboratory at the University of Utah), which should be compared with several examples of visual deficits shown below.
Loss of acuity
A simulation of reduced acuity, in which detail is no longer discriminable
Reduced contrast sensitivity
A simulation of loss of contrast sensitivity. Many low vision defects involve a loss of both acuity and contrast sensitivity.
Peripheral field loss
A simulation of peripheral field loss, often called tunnel vision.
Central field loss
A simulation of central field loss. The simulation combines a loss of foveal vision with the normal reduction in acuity for off-fovea vision.
This is a multi-disciplinary project involving personnel from the University of Minnesota, the University of Utah, and Indiana University, and supported by the National Eye Institute of the National Institutes of Health grant 1 R01 EY017835-01.
