                             CERTIFICATION
                      Certification of Treasurer

I, Andrew Ashton, Treasurer, certify that:

1.  I have reviewed this quarterly report on Form 10-Q 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.
