Abstract:

Preflight, in-flight, and postflight tests of the visual acuity of both members of the Gemini V and Gemini VII crews showed no statistically significant change in their visual capability. Observations of a prepared and monitored pattern of rectangles made at a ground site near Laredo, Texas confirmed that the visual performance of the astronauts in space was within the statistical range of their respective preflight thresholds, and that laboratory visual acuity data can be combined with environmental optical data to predict correctly mans limiting visual capability to discriminate small objects on the surface of the earth in daytime.
