Glare is defined by the International Commission o n Illumination (CIE) as a “ condition of vision in which there is discomfort or a reduction in the ability to see details or objects caused by an unsuitable distribution or range of luminance or by extreme contrasts ”

Disability glare: loss and recovery • Onset of peripheral glare source produces large initial visibility loss (threshold elevation) • If glare source left on sensitivity improves (threshold decreases) until a steady state (continuous) glare sensitivity level is reached • Disability glare formulas generally refer to

• Test each eye separately by holding a clean tissue over one eye at a time Cover the left eye and tes t the right eye first • View the Reading Near Chart 14 inches from your eyes Use the diagonal of letter-size paper to measure 14 inches (see illustration to the left)

for Lasting Glare Control? 6 Maximum glare control and optimal comfort require 1 T vis or lower that remains stable over time Based on knowledge gained through installing electrochromic glass in over 50 million square feet of building space View knows true glare control and occupant comfort require visible light transmittance of 1 T
