Smog Helmet (Sep, 1949)

The lady under this plastic headpiece is getting a dose of smog, made up of smoke and fog. Photoelectric cells attached to glassless goggles record blinks due to eye irritation. She reads a book to produce uniform reactions. The test is part of a study being made by Stanford Research Institute to find out more about the smog that often blots out Los Angeles’ sunshine.
