Dear Ms. Veator:

Thank you for our conversation this morning in reviewing your questions and the Company’s draft responses in an effort for the Company to respond fully to you questions.  As a result, I would like to request on behalf of Applied Visual Sciences, Inc. an extension to respond to your July 8, 2010 Comment Letter.  As discussed, the request for an additional week is so that the Company can further review the related guidance on the anti-dilutive provisions, and expand more fully our response related to the convertible debenture warrants.

If you have any question regarding this request, please feel free to contact the undersigned at (703) 464-5495, extension 143.

Respectfully submitted,

/s/ Gregory E. Hare
