Luckiesh and Moss on reading illumination

Abstract

The conclusions of Luckiesh and Moss concerning the optimal intensity of illumination for reading are criticized on several bases. Adoption of the percentage score technique for handling and presenting findings is questioned, and the results of several experiments (Luckiesh and Moss) are reinterpreted in terms of the differences between means. Nervous muscular tension, reading rate, and blinking rate are thus studied with the conclusion that experimental evidence indicates that 15-foot candles should be recommended for ordinary study and reading.
