A Pacific University research study of 36 participants did in fact find significant differences in irritation or burning of the eyes, tearing, or watery eyes, dry eyes, and tired eyes, that were each improved by Gunnar lenses versus placebo lenses, however there was no significant difference in glare reduction or contrast improvement versus the placebo lenses.[9]The study also never tested the alternative method of simulating the effect of Gunnar lenses by simply adjusting the computer monitor's parameters such as brightness, contrast and color temperature.
