AMENDMENT NO. 6 TO SCHEDULE 13D

             This Amendment No. 6 to Schedule 13D (this “Amendment”) is being filed on behalf of (i) Paragon Associates and Paragon Associates II Joint Venture, a joint venture (“Paragon JV”) formed by Paragon Associates, Ltd., a Texas limited partnership (“Paragon”), Paragon Associates II, Ltd., a Texas limited partnership (“Paragon II”), and Paragon Associates III, Ltd. a Texas limited partnership (“Paragon III”), (ii) Paragon JV Partners, LLC, a Texas limited liability company (“Paragon GP”), and (iii) Bradbury Dyer III (“Mr. Dyer”, and collectively with Paragon JV and Paragon GP, the “Reporting Persons”).  This Amendment further modifies the original Schedule 13D filed with the Securities and Exchange Commission on January 8, 2009 (the “Original 13D), as amended by the Amendment No. 1 to Schedule 13D filed with the Securities and Exchange Commission on February 10, 2009, as amended by the Amendment No. 2 to Schedule 13D filed with the Securities and Exchange Commission on November 4, 2013, as amended by the Amendment No. 3 to Schedule 13D filed with the Securities and Exchange Commission on July 27, 2015, as amended by the Amendment No. 4 to Schedule 13D filed with the Securities and Exchange Commission on August 24, 2015, as amended by the Amendment No. 5 to Schedule 13D filed with the Securities and Exchange Commission on April 13, 2021 (the Original 13D, as so amended, the “Schedule 13D”), relating to shares of common stock, $0.01 par value (the “Common Stock”) of Iridex Corporation, a Delaware corporation (the “Issuer”).

This Amendment relates to Common Stock sold by Mr. Dyer for the account of Paragon JV on behalf of Paragon, Paragon II and Paragon III.  Paragon GP serves as the general partner of each of Paragon, Paragon II and Paragon III and as the investment advisor of Paragon JV and may direct the vote and disposition of the 980,674 shares of Common Stock held by Paragon JV.  As the sole and managing member of Paragon GP, Mr. Dyer may direct Paragon GP to direct, and, as the authorized agent to Paragon JV, may direct, the vote and disposition of the 980,674 shares of Common Stock held by Paragon JV.

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and restated in its entirety to read as follows: 

(a)    As of July 2, 2021, Paragon JV, by virtue of carrying out the purposes of Paragon, Paragon II and Paragon III per the joint venture agreement of Paragon JV, a copy of which was filed as Exhibit 2 to the Original 13D and is incorporated herein by reference, as subsequently amended by the First Amendment thereto, a copy of which was filed as Exhibit 3 to the Original 13D, beneficially owns 980,674 shares of Common Stock, which represents 6.3% of the Issuer’s outstanding shares of Common Stock.

       The percentage of ownership of the Reporting Persons, as reported in this Schedule 13D was calculated by dividing (i) 980,674 shares of Common Stock owned by Paragon JV, by (ii) 15,625,800 shares of Common Stock outstanding as of May 6, 2021 based upon the Form 10-Q filed with the Securities and Exchange Commission on May 12, 2021.

       Paragon GP does not have direct beneficial ownership of the 980,674 shares of the Issuer’s Common Stock; however, Paragon GP, as the general partner of each of Paragon, Paragon II and Paragon III, may be deemed, for purposes of determining beneficial ownership pursuant to Rule 13d-3, to have indirect beneficial ownership of such shares.
