VariGuard to Exhibit Its SPD-SmartGlass Products a

CHICAGO, IL--(Marketwired - May 30, 2017) - This week VariGuard, a business unit of Research Frontiers Inc. ( NASDAQ : REFR ), showcases its SPD-SmartGlass products at the 45 ^th annual meeting of the American Institute for Conservation of Historic and Artistic Works (AIC) in Chicago at booth #107.

The theme of the AIC meeting is Treatment 2017: Innovation in Conservation and Collection Care . Seth Van Voorhees, President of VariGuard, commented, "Conservators constantly face the dilemma of how to protect light-sensitive artifacts from damage. While VariGuard display systems provide protection against UV exposure, they are unique in their ability to also control visible light to dramatically limit the amount of damaging exposure from these wavelengths."

VariGuard's display panels instantly change the tint of glass, from optically clear to dark, automatically using motion or other sensors, or at the touch of a button. As a result, exposure to visible light is limited to when the artifact or document is actually being viewed. For example, the Smithsonian National Postal Museum reported that when using VariGuard display panels "...artifacts in the case were receiving over 90% less light then the exterior of the case."

VariGuard products are available for use in the design of new display cases and frames. In addition, existing displays can be upgraded to provide VariGuard's light-protection features at a fraction of the cost of a new system.
