    I, Joseph M. Harary, President, Chief Operating Officer, Treasurer and
Chief Accounting Officer of Research Frontiers Incorporated ("RFI"
or the "Registrant") certify that:

1.  I have reviewed this annual report on Form 10-K/A of RFI;

2. Based on my knowledge, this report does not contain
any untrue statement of a material fact or omit to state a material
fact necessary to make the statements made, in light of the
circumstances under which such statements were made, not
misleading with respect to the period covered by this report;

3.    Based on my knowledge, the financial statements, and
other financial information included in this report, fairly present
in all material respects the financial condition, results of
operations and cash flows of the registrant as of, and for, the
periods presented in this report;

4.    The registrant's other certifying officer and I are
responsible for establishing and maintaining disclosure controls
and procedures (as defined in Exchange Act Rules 13a-15(e)
and 15d-15(e)) for the registrant and have:

(a)   Designed such disclosure controls and procedures, or
caused such disclosure controls and procedures
to be designed under my supervision, to ensure that material
information relating to the registrant, including its consolidated
subsidiaries, is made known to us by others within those entities,
particularly during the period in which this report is being
prepared;

(b)   Evaluated the effectiveness of the registrant's disclosure
controls and procedures and presented in this report
our conclusions about the effectiveness of the disclosure
controls and procedures, as of the end of the period covered by
this report based on such evaluation; and

(c)   Disclosed in this report any change in the registrant's  internal
control over financial reporting that occurred
during the registrant's  most recent fiscal quarter (the registrant's
fourth fiscal quarter in the case of an annual report) that has
materially affected, or is reasonably likely to materially affect,
the registrant's  internal control over financial reporting; and

5.    The registrant's other certifying officer and I have
disclosed, based on my most recent evaluation of internal
control over financial reporting, to the registrant's  auditors and
the audit committee of the registrant's  board of directors (or
persons performing the equivalent functions):

(a)   All significant deficiencies and material weaknesses in
the design or operation of internal control over
financial reporting which are reasonably likely to adversely
affect the registrant's  ability to record, process, summarize and
report financial information; and

(b)   Any fraud, whether or not material, that involves
management or other employees who have a significant role in
the registrant's  internal control over financial reporting.
