The visual effects of repeated exposure to CO2 at levels commonly regarded as innocuous were investigated. Exposure to CO2 varied cyclically from .03 air to 3.0, at 1 atmosphere pressure, every 24 hours for a period of 6 days. A battery of visual tests was administered during this period and in control periods both before and after the CO2 exposure. Among the various tests, night vision sensitivity and color sensitivity for green were the only ones which repeatedly detected impairment of efficiency during the period of exposure. All other visual functions remained normal.
