               SMART GLASS COMPANY RESEARCH FRONTIERS
            RAISES $2.5 MILLION IN NEW CAPITAL FOR EXPANSION


Woodbury, New York - September 17, 2010. A group of accredited investors
has invested $2.5 million in Research Frontiers Inc. (Nasdaq: REFR), the
developer and licensor of patented SPD-Smart(tm) light-control film technology.
The investors received 641,026 shares of Research Frontiers common stock at
a price of $3.90 per share, which was the average market price of Research
Frontiers stock on September 15, 2010, the day the transaction was priced.
In addition, the investors in this stock offering received 128,205 five-year
warrants to purchase Research Frontiers common stock at a price of $6.25 per
share. These securities were sold pursuant to Research Frontiers' effective
shelf-registration statement filed with the SEC.

Joseph M. Harary, President and CEO of Research Frontiers, noted: "This
investment and its timing make perfect sense to those that follow the smart
glass industry in general, and Research Frontiers and our leading SPD-Smart
light-control technology in particular. With business activity in the SPD
industry expanding at Research Frontiers and especially at our larger
licensees, more projects being announced or recently completed using our
SPD-SmartGlass technology, and some very highly visible products using our
technology currently planned to be launched internationally, we are adding
resources and people, especially in the sales, marketing, and business
development areas. We are moving at light speed."

Mr. Harary continued: "I also thank our shareholders and the investors in
this round of financing for their continued support as we grow our business
and the SPD-Smart products industry. These investors include people who
participated in our prior financing rounds, and internationally-known
architects, and owners, operators and developers of some of the world's
largest and most prestigious buildings. Their participation is part of a
growing awareness of the benefits that SPD-SmartGlass technology brings.
Independent data shows that SPD-SmartGlass technology can be used to make
the highest-performing and most energy-efficient windows in the world.
Architects, engineers, designers and new product developers are also
beginning to utilize these and other benefits including energy savings
from solar heat gain control and management, reduction of interior
lighting costs due to enhanced daylight harvesting, and increased comfort,
safety, functionality, protection from harmful UV radiation, and security."

SPD-Smart light-control film technology transforms widely used products -
windows, skylights, curtainwalls, partitions, sunroofs and more - into
products that allow users to instantly and precisely control the light,
glare and heat entering a building or vehicle. SPD-SmartGlass is instantly
tunable to an infinite number of light transmission states regardless of
window size, and easily adapts to individual preferences using control
devices ranging from basic dimmer switches and photosensors to those that
are integrated into a building's or vehicle's intelligent control system.
These unequalled performance characteristics help optimize energy-savings
and human comfort, and they offer many other desired benefits such as
increased security, noise reduction, protection from harmful ultraviolet
light and the potential for aesthetically distinctive designs. Additional
information about SPD technology and SPD-Smart windows and other products
can be found at www.SmartGlass.com.
