Ladies and Gentlemen:

We have acted as a counsel to Second Sight Medical Products, Inc., a California corporation (the “Company” or “Registrant”) in connection with the Registration Statement on Form S-8 (the “Registration Statement”) to be filed by the Company with the Securities and Exchange Commission on or about the date hereof, in connection with the registration under the Securities Act of 1933, as amended (the “Act”), of an aggregate of 2,500,000 shares of common stock (the “Shares”) of Second Sight Medical Products, Inc. (the “Company”), no par value, consisting of (i) 2,000,000 additional shares of common stock of the Company, issuable under the Registrant’s 2011 Equity Incentive Plan, as amended (the “Option Shares”), and (ii) 500,000 shares of common stock of the Company (the “Plan Shares”), issuable under the Registrant’s 2015 Employee Stock Purchase Plan, as amended (the “ESPP”).

You have requested our opinion as to the matters set forth below in connection with the Registration Statement.  For purposes of rendering that opinion, we have examined the Plan, the ESPP, the Registration Statement, the Company’s Restated Articles of Incorporation, Amended and Restated Bylaws, and the corporate actions of the Company that provide for the issuance of the Shares, and we have made such other investigation as we have deemed appropriate. We have examined and relied upon certificates of public officials and, as to certain matters of fact that are material to our opinion we have also relied on a certificate of an officer of the Company. 

For the purposes of this opinion letter, we have assumed that: (a) each document submitted to us is accurate and complete; (b) each such document that is an original is authentic; (c) each such document that is a copy conforms to an authentic original; (d) all signatures on each such document are genuine; and that (e) the Company is and shall remain at all times a corporation duly incorporated, validly existing and in good standing under the laws of the State of California. We have further assumed the legal capacity of natural persons, and we have assumed that each party to the documents we have examined or relied on has the legal capacity or authority and has satisfied all legal requirements that are applicable to that party to the extent necessary to make such documents enforceable against that party. We have not verified any of those assumptions.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Shares, when acquired, issued and sold in the manner referred to in the Plan and/or in the ESPP and pursuant to the agreements that accompany the Plan and the ESPP, will be legally and validly issued, fully paid, and nonassessable and have been authorized by all necessary corporate actions of the Company.

The opinion expressed herein is limited to the California Corporations Code, including the applicable provisions of the California Constitution and the reported judicial decisions interpreting such law, in each case as currently in effect, and we express no opinion as to the effect of the laws of any other jurisdiction.

The opinion expressed herein is limited to the matters specifically set forth herein and no other opinion should be inferred or implied beyond the matters expressly stated. We assume no obligation to supplement this opinion if any applicable law changes after the date hereof or if we become aware of any fact that might change the opinion expressed herein after the date hereof.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement to effect registration of the Shares under the Act. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Act or the rules and regulations promulgated thereunder.
