Carbon Monoxide and Night Vision
The presence of carbon monoxide results in hypoxia which will affect
night vision in the same manner and extent as hypoxia from high
altitudes. Even small levels of carbon monoxide have the same effect
as an altitude increase of 8,000 to 10,000 ft. Smoking several
cigarettes can result in a carbon monoxide saturation sufficient to
affect visual sensitivity equal to an increase of 8,000 ft. of altitude.
