        Re:    Registration Statement on Form S-3

Ladies and Gentlemen:

        We have acted as counsel to Microvision, Inc., a Washington corporation (the "Company"), in connection with the Registration Statement on Form S-3 (the "Registration Statement") filed by the Company with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Securities Act"), with respect to (i) convertible debt securities of the Company (the "Debt Securities"); (ii) shares of preferred stock, no par value, of the Company (the "Preferred Stock"); (iii) shares of common stock, no par value, of the Company (the "Common Stock"); (iv) warrants for the purchase of Debt Securities, Preferred Stock, Common Stock or other securities of the Company (the "Warrants" and collectively with the Debt Securities, Preferred Stock and Common Stock are the "Offered Securities"); (v) 200,000 shares of common stock of the Company issuable upon the exercise of certain warrants (the "Warrant Shares") and (vi) the issuance of 7,400 shares of common stock to the University of Washington (collectively with the Warrant Shares, the "Selling Shareholder Shares"). The Offered Securities being registered under the Registration Statement will have an aggregate offering price of up to $20,000,000 and will be offered on a continued or delayed basis pursuant to the provisions of Rule 415 under the Securities Act.

        Unless otherwise provided in any prospectus supplement forming a part of the Registration Statement relating to any particular series of Debt Securities, the Debt Securities will be issued under one or more indentures (each, an "Indenture") between the Company and one or more trustees chosen by the Company that are qualified to act as such under the Trust Indenture Act of 1939, as amended (the "Trustee") substantially in the form attached as an exhibit to or incorporated by reference in the Registration Statement. The Preferred Stock will be issued pursuant to one or more Statements of Rights and Preferences (each, a "Statement of Rights") relating to a particular series of Preferred Stock. The Warrants will be issued pursuant to one or more warrant agreements (each, a "Warrant Agreement") relating to particular Debt Securities, shares of Preferred Stock, shares of Common Stock or other securities of the Company issuable upon exercise of the Warrants.

        We have reviewed the corporate action of the Company in connection with the foregoing and have examined such documents, corporate records, and other instruments as we have deemed necessary for the purposes of this opinion. In such examination, we have assumed (i) the authenticity of original documents and the genuineness of all signatures, (ii) the conformity to the originals of all documents submitted to us as copies and (iii) the truth, accuracy, and completeness of the information, representations and warranties contained in the records, documents, instruments and certificates we have reviewed.
