                              SUMMARY

         You should read the entire prospectus, including the section entitled
'Risk Factors,' carefully before making an investment decision.

                            THE COMPANY

     Research Frontiers Incorporated ("Research Frontiers" or the
"Company") develops and licenses its suspended particle technology for
controlling the amount of light passing through a device. Such
suspended particle devices are often referred to as "SPDs," "light
valves," or "SPD-Smart " products.

     SPDs use microscopic light-absorbing particles that are either in
a liquid suspension or a film. The microscopic particles align when an
electrical voltage is applied.  This permits light to pass through the
device, and allows the amount of light to be controlled. Our offices
are located at: 240 Crossways Park Drive, Woodbury, NY 11797
(telephone: 516-364-1902).




















                   RISK FACTORS

         In addition to the other information in this prospectus, you should
carefully consider the following factors in evaluating us and our business
before purchasing the shares of common stock offered hereby. This prospectus
contains, in addition to historical information, forward-looking statements that
involve risks and uncertainties. Our actual results could differ materially.
Factors that could cause or contribute to such differences include, but are not
limited to, those discussed below, as well as those discussed elsewhere in this
prospectus, including the documents incorporated by reference.

There are risks associated with investing in companies such as ours who
are engaged in research and development.  Because of these risks, you
should only invest if you are able to bear the risk of losing your entire
investment.  Before investing, in addition to risks which could apply to
any issuer or offering, you should also consider the business we are in
and the following:

Research Frontiers has a history of operating losses, expects to incur
additional losses in the future, and consequently will need additional
funds in the future to continue its operations.  To date, Research
Frontiers' has lost money, and we expect to lose money in the
foreseeable future.  Because we expect that our future revenues will
consist primarily of license fees (which have not been significant to date),
unless our licensees produce and sell products using our technology,
Research Frontiers will not be profitable. There is no guarantee
that we will ever be profitable. Since Research Frontiers was started
in 1965 through December 31, 2003, its total net loss was $50,922,625.
In 2003 our net loss was $4,772,308 and was $3,951,116 in 2002.

We have funded our operations by selling our common stock to investors.
If we need additional money, there is no guarantee that it will be available
when we need it, or on favorable terms. The Company will need to raise
additional capital no later than the first quarter of 2005 if operations,
including research and development and marketing, are to be maintained
at current levels. If the Company cannot raise additional funds,
it will be required to reduce expenses during 2004. Eventual success
of the Company and generation of positive cash flow will be dependent
upon the extent of  commercialization of products using the
Company's technology by the Company's licensees and payments
of continuing royalties on account thereof.

Research Frontiers depends upon the activities of its licensees in order
to be profitable.  We do not directly manufacture or market products
using SPD technology.  Although a variety of products have been sold by our
licensees, and since it is up to our licensees to decide when and if they
will introduce products using SPD technology, we cannot predict when
and if our licensees will generate substantial sales of such products.
Research Frontiers' SPD technology is currently licensed to 33 companies.
Other companies are also evaluating the technology for use in various
products. In the past, some companies have evaluated our technology
without proceeding further.  Also, we do not intend to manufacture
products using SPD technology.  Instead we intend to continue to
license our technology to manufacturers of end products, films and emulsion.
We expect that our licensees would be primarily responsible for marketing
and manufacturing, but we are also engaging in market development activities.

Products using SPD technology have only recently been introduced into the
marketplace.  Developing products using new technologies can be risky
because problems, expenses and delays frequently occur.  Research
Frontiers cannot control whether or not its licensees will develop SPD
products.  Some of our licensees appear to be more active than others, some
appear to be better capitalized than others, and some licensees appear
to be inactive such as General Electric, Polaroid and Global Mirror.
There is no guarantee when or if our licensees will
successfully produce any commercial product using SPD technology.

SPD technology is the only technology Research Frontiers works with,
so that our success depends upon the viability of SPD technology which
has yet to be proven. We have not fully ascertained the performance and
long-term reliability of our technology, and therefore there is no
guarantee that our technology will successfully be incorporated into all
of the products which we are targeting for use of SPD technology. We
expect that different product applications for SPD technology will have
different performance and reliability specifications.  For example, SPD
eyewear requiring batteries may need to use lower voltages than SPD
windows used in homes or offices, yet may not need to last as long or be
exposed to as harsh an environment. We expect that our licensees will
primarily be responsible for reliability testing, but that we may also
continue to do reliability testing so that we can more effectively focus
our research and development efforts towards constantly improving the
performance characteristics and reliability of products using SPD technology.

                              PART II

            INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 13.  Disclosure of Commission Position on Indemnification for
          Securities Act Liabilities.

As described in Item 15, the Certificate of Incorporation of Research
Frontiers provides for the indemnification of certain persons.  Insofar as
indemnification for liabilities arising under the Securities Act of 1933
(the "Act") may be permitted to directors, officers and controlling
persons of the registrant pursuant to the Certificate of Incorporation or
By-Laws of Research Frontiers, or otherwise, the registrant has been
informed that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

Item 15.  Indemnification of Directors and Officers.

Article EIGHTH of Research Frontiers' Certificate of Incorporation
provides for the indemnification of Research Frontiers' officers and
directors to the fullest extent permitted by Section 145 of the Delaware
General Corporation Law (the "GCL").

Section 145 of the GCL provides as follows:

     145 Indemnification of Officers, Directors, Employees and Agents;
Insurance

     (a) A corporation shall have power to indemnify any person who
was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of
the corporation) by reason of the fact that the person is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by the
person  in connection with such action, suit or proceeding if the person
acted in good faith and in a manner the person reasonably believed to be
in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe the person's conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself,
create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that the person's conduct
was unlawful.

     (b) A corporation shall have the power to indemnify any person
who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that
the person is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust, or other enterprise against expenses (including
attorneys' fees) actually and reasonably incurred by the person in
connection with the defense or settlement of such action or suit if the
person acted in good faith and in a manner the person reasonably
believed to be in or not opposed to the best interests of the corporation
and except that no indemnification shall be made in respect of any claim,
issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Court of
Chancery or such other court shall deem proper.

     (c) To the extent that a present or former director or officer of a
corporation has been successful on the merits or otherwise in defense of
any action, suit or proceeding referred to in subsections (a) and (b) of
this section, or in defense of any claim, issue or matter therein, such
person shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by such person in connection therewith.

     (d) Any indemnification under subsections (a) and (b) of this
section (unless ordered by a court) shall be made by the corporation only
as authorized in the specific case upon a determination that
indemnification of the present or former director, officer, employee or
agent is proper in the circumstances because the person has met the
applicable standard of conduct set forth in subsections (a) and (b) of this
section. Such determination shall be made with respect to a person who
is a director or officer at the time of such determination, (1) by a
majority vote of the directors who are not parties to such action, suit or
proceeding, or (2) by a committee of such directors designated by a
majority vote of such directors, even though less than a quorum, or (3) if
there are no such directors, or if such directors so direct, by independent
legal counsel in a written opinion, or (4) by the stockholders.

     (e) Expenses (including attorneys' fees) incurred by an officer or
director in defending any civil, criminal, administrative or investigative
action, suit or proceeding may be paid by the corporation in advance of
the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such
amount if it shall ultimately be determined that such person is not
entitled to be indemnified by the corporation as authorized in this
section. Such expenses (including attorneys' fees) incurred by former
directors and officers or other employees and agents may be so paid
upon such terms and conditions, if any, as the corporation deems
appropriate.

     (f) The indemnification and advancement of expenses provided by,
or granted pursuant to, the other subsections of this section shall not be
deemed exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in such person's official capacity and as to
action in another capacity while holding such office.

     (g) A corporation shall have power to purchase and maintain
insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request
of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
any liability asserted against such person and incurred by such person in
any such capacity, or arising out of such person's status as such, whether
or not the corporation would have the power to indemnify such person
against such liability under this section.

     (h) For purposes of this section, references to "the corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued,
would have had power and authority to indemnify its directors, officers,
and employees or agents, so that any person who is or was a director,
officer, employee or agent of such constituent corporation, or is or was
serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, shall stand in the same position under
this section with respect to the resulting or surviving corporation as such
person would have with respect to such constituent corporation if its
separate existence had continued.

     (i) For purposes of this section, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include
any excise taxes assessed on a person with respect to any employee
benefit plan; and references to "serving at the request of the corporation"
shall include any service as a director, officer, employee or agent of the
corporation which imposes duties on, or involves services by, such
director, officer, employee, or agent with respect to an employee benefit
plan, its participants or beneficiaries; and a person who acted in good
faith and in a manner such person reasonably believed to be in the
interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best
interests of the corporation" as referred to in this section.

     (j) The indemnification and advancement of expenses provided by,
or granted pursuant to, this section shall, unless otherwise provided
when authorized or ratified, continue as to a person who has ceased to be
a director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

     (k) The Court of Chancery is hereby vested with exclusive
jurisdiction to hear and determine all actions for advancement of
expenses or indemnification brought under this section or under any
bylaw, agreement, vote of stockholders or disinterested directors, or
otherwise.  The Court of Chancery may summarily determine a
corporation' obligation to advance expenses (including attorneys' fees).

     Article NINTH of Research Frontiers' Certificate of Incorporation
provides for the elimination of any personal liability for monetary
damages of directors to the Corporation or its stockholders for breach of
fiduciary duty, for negligence or for taking or omitting to take any action
to the fullest extent permitted by Section 102(b) (7) of the GCL.

     Section 102(b) (7) of the GCL provides as follows:

     (b) In addition to the matters required to be set forth in the
certificate of incorporation by subsection (a) of this section, the
certificate of incorporation may also contain any or all of the following
matters:

     (7) A provision eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for
breach of fiduciary duty as a director, provided that such provision shall
not eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under section 174 of this
Title, or (iv) for any transaction from which the director derived an
improper personal benefit. No such provision shall eliminate or limit the
liability of a director for any act or omission occurring prior to the date
when such provision becomes effective. All references in this paragraph
to a director shall also be deemed to refer (x) to a member of the
governing body of a corporation which is not authorized to issue capital
stock, and (y) to such other person or persons, if any, who, pursuant to a
provision of the certificate of incorporation in accordance with section
141(a) of this title, exercise or perform any of the powers or duties
otherwise conferred or imposed upon the board of directors by this title.
