          Research Frontiers Licenses SmartGlass International
           to Make SPD-Smart Architectural Window Products

United Kingdom, Ireland and Woodbury, NY-March 19, 2007. Research Frontiers
Incorporated (Nasdaq: REFR) and SmartGlass International Ltd. announced
today that SmartGlass International Ltd. has acquired a non-exclusive
license to use Research Frontiers' patented SPD-Smart(tm) light-control
technology for architectural smart windows, skylights and similar products
in the United Kingdom and Republic of Ireland. The minimum annual royalties
and other license terms were not disclosed.

SmartGlass International's SPD-Smart products can be manually or automatically
"tuned" to precisely control the amount of light, glare and heat passing
through glass or plastic. These products foster innovative building design
opportunities never before available.

Glass facades using patented SPD light-control technology reduce the need
for air conditioning during the summer months and heating during winter.
The ability to instantly switch the glass to maximize daylight when it's
really needed and to provide controllable solar shading during peak light
conditions is unique.

John Browne, Executive Director of SmartGlass International, noted: "The use
of intelligent glass provides added value and increased flexibility in new
building design, improves working environments and buildings ergonomics, saves
energy, and increases the well being of building occupants. As a company
dedicated to bringing environmentally friendly "green" building products and
unique design abilities to our customers, we are pleased to now have the
expanded resources through the merger of the smartglass businesses of
SmartGlass Ireland and Vision (Environmental Innovation) Ltd. Under license
from Research Frontiers, we can now offer SPD-Smart products over a wider
geographic area, and we plan continued expansion of this very attractive
line of our business. SmartGlass International believes with the recent
announcement of stringent legislation on the reduction of CO2 emissions,
and the availability of wide-width SPD-Smart film, the architectural smart
glass market is set to grow at a significant rate over the next five
years." Further details can be found at www.smartglassinternational.com
