Re:         Second Sight Medical Products, Inc. - Registration Statement on Form S-1

Ladies and Gentlemen:

We have acted as counsel for Second Sight Medical Products, Inc., a California corporation (the "Company"), in connection with the Registration Statement on Form S-1 (the “Registration Statement”) relating to the registration under the Securities Act of 1933 of (i)  non-transferable subscription rights (the “Rights”) to be distributed by the Company without consideration in connection with a rights offering (the “Rights Offering”) to holders of record of common stock, no par value, of the Company (the “Common Stock”), owned on the record date, as more fully set forth within the Registration Statement, including amendments thereto, (ii) units (“Units”) issuable upon exercise of the Rights, each Unit entitling the holder thereof to purchase one share of Common Stock and a warrant (each a “Warrant,” and collectively, the “Warrants”) representing the right to purchase one share of Common Stock, (iii) shares of Common Stock, all of which are authorized but heretofore unissued shares to be offered and sold by the Company, underlying the Units (the “Rights Shares”), and (iv) the Warrants; and (v)  shares of Common Stock, all of which are authorized but heretofore unissued to be offered and sold by the Company, issuable upon exercise of the Warrants (the “Warrant Shares”).

In connection with rendering this opinion letter, we have reviewed (i) the Registration Statement, (ii) the Articles of Incorporation of the Company, as amended to the date hereof, (iii) the Bylaws of the Company, as amended to the date hereof, (iv) certain resolutions adopted by the board of directors of the Company relating to the registration of the Rights, the Units, the Rights Shares, Warrants and Warrant Shares, (v) the terms of the Rights Offering and related matters, (vi) a specimen certificate representing the Rights; and (viii) such other documents as we have considered appropriate for the purposes of this opinion.

For purposes of this opinion, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity of the text of each document filed with the Securities and Exchange Commission (the “Commission”) through the Commission’s Electronic Data Gathering, Analysis and Retrieval System, the conformity to original documents of all documents submitted to us as certified or copies, and the accuracy and the authenticity of the originals of such copies. As to any facts material to the opinions expressed herein which we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others. Except as expressly set forth herein, we have not undertaken any independent investigation (including, without limitation, conducting any review, search or investigation of any public files, records or dockets) to determine the existence or absence of the facts that are material to our opinions, and no inference as to our knowledge concerning such facts should be drawn from our reliance on the representations of the Company in connection with the preparation and delivery of this letter.

We have not examined the laws of any state other than California and we express no opinion as to the laws of any jurisdiction other than the laws of the State of California and, to the extent specifically referred to herein, the federal laws of the United States of America, insofar as those laws are in effect as of the date hereof.

Based upon the foregoing and subject to the limitations, qualifications and assumptions set forth herein, we are of the opinion that:

1.          The Rights have been duly authorized and, when issued, will be the valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except to the extent that enforcement thereof may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium, receivership or other laws relating to or affecting creditors’ rights generally, and to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity).

2.          The Units have been duly authorized and, when issued upon exercise of the Rights in accordance with the terms of the Rights, will be validly issued, fully paid and nonassessable.

3.          The Rights Shares have been duly authorized and, if issued on the date hereof upon exercise of the Rights in accordance with the terms of the Rights, would be validly issued, fully paid and nonassessable.

4.          The Warrants have been duly authorized and, if issued on the date hereof upon exercise of the Rights in accordance with the terms of the Rights, and when duly executed and delivered by the Company in the manner described in the Registration Statement and in accordance with the resolutions adopted by the Board of Directors of the Company, will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent transfer and similar laws affecting or relating to the rights of creditors generally, by general principles of equity (regardless of whether considered in a proceeding in equity or at law), and by requirements of reasonableness, good faith and fair dealing.

5.          The Warrant Shares have been duly authorized and, if duly issued and sold against the payment therefor on the date hereof in accordance with the terms of the Warrants, would be validly issued, fully paid and nonassessable.

We hereby consent to the filing of this letter as an exhibit to the Registration Statement and to the reference to this firm under the caption “Legal Matters” in the Registration Statement. In giving this consent, we do not hereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Securities and Exchange Commission promulgated thereunder. This opinion is expressed as of the date of effectiveness of the Registration Statement unless otherwise expressly stated, and we disclaim any undertaking to advise you of any subsequent changes in the facts stated or assumed herein or of any subsequent changes in applicable laws after that date.

Very truly yours,
