                Certification of Treasurer

I, Andrew J. Ashton, Treasurer, certify that:

1.  I have reviewed this annual report on Form 10-KSB of
    Lightwave Logic, Inc.;
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 small business issuer as of, and
    for, the periods presented in this report;
4.  The small business issuer's other certifying officer(s) 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)) and internal control over financial
    reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-
    15(f)) for the small business issuer and have:
    (a)  Designed such disclosure controls and procedures, or caused
         such disclosure controls and procedures to be designed under our
         supervision, to ensure that material information relating to the
         small business issuer, 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 small business issuer'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 small business
         issuer's internal control over financial reporting that occurred
         during the small business issuer's most recent fiscal quarter
         (the small business issuer's fourth fiscal quarter in the case of
         an annual report) that has materially affected, or is reasonably
         likely to materially affect, the small business issuer's internal
         control over financial reporting; and
5.  The small business issuer's other certifying officer(s) and I have
    disclosed, based on our most recent evaluation of internal control
    over financial reporting, to the small business issuer's auditors and
    the audit committee of the small business issuer'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 small
         business issuer'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 small
         business issuer's internal control over financial reporting.
