    The original finding aid described this as: Description: STS-44 Pilot Terence T. Henricks tests his visual acuity with the Visual Function Tester 1 (VFT-1) on the middeck of Atlantis, Orbiter Vehicle (OV) 104. VFT-1 measures changes in the vision of an astronaut in microgravity. It is a hand-held, battery-powered device with a binocular eyepiece that uses controlled illumination to present a variety of visual targets for testing primarily visual acuity and eye interaction effects, such as stereopsis and eye dominance. This experiment is being conducted in conjunction with the Military Man in Space activities.
