EXHIBIT 10.7

                   EYE DYNAMICS INC. -- HRL LABORATORIES, LLC

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT (this "AGREEMENT") is made as of
November 18, 2002, by and between HRL Laboratories, LLC ("HRL"), having a

principal place of business at 3011 Malibu Canyon Road, Malibu, California
90265, and Eye Dynamics Inc. ("EDI"), located at 2301 West 205th Street, Suite
106, Torrance, CA 90501. HRL and EDI may be referred to individually as a
"Party" or collectively as the "Parties."

         The Parties to this Agreement are Parties to a Technology Development
Agreement of even date herewith (the "TDA"). In order to induce HRL to enter
into the TDA, EDI has agreed to provide the registration rights set forth in
this Agreement. The execution and delivery of this Agreement is a condition to
HRL's obligations under the TDA. Unless otherwise provided in this Agreement,
capitalized terms used herein shall have the meanings set forth in Article 5
hereof.

         The Parties hereto agree as follows:

1.       DEMAND REGISTRATION.

         (a) REQUESTS FOR REGISTRATION. At any time after the 1st anniversary of
the Effective Date under the TDA or such earlier time as EDI has completed a
public offering of its securities under the Securities Act, holders of
Registrable Securities may request registration under the Securities Act of all
or any portion of their Registrable Securities on Form S-1 or any similar
long-form registration ("LONG-FORM REGISTRATIONS"), or Form S-2 or S-3 or any
similar short-form registration ("SHORT-FORM REGISTRATIONS"), if available. All
registrations requested pursuant to this Section 1.1 are referred to herein as
"DEMAND REGISTRATIONS." Holders of Registrable Securities may make up to three
(3) Demand Registrations in any order or combination of Long-Form Registrations
or Short-form Registrations. Each request for a Demand Registration shall
specify the approximate number of Registrable Securities requested to be
registered and the anticipated per share price range for such offering. Within
ten days after receipt of any such request, EDI shall give written notice of
such requested registration to all other holders of Registrable Securities and,
subject to the terms of Section 1.4 hereof, shall include in such registration
all Registrable Securities with respect to which EDI has received written
requests for inclusion therein within 15 days after the receipt of EDI's notice.

         (b) EXPENSES. EDI shall pay all Registration Expenses associated with a
Demand Registration. A registration shall not count as one of the permitted
Demand Registrations until it has become effective and the last or any
subsequent Demand Registration pursuant to Section 1.1 above shall not count as
one of the permitted Demand Registrations unless the holders of Registrable
Securities are able to register and sell at least 90% of the Registrable
Securities they have requested to be included in such registration; provided
that in any event EDI shall pay all Registration Expenses in connection with any
registration initiated whether or not it has become effective and whether or not
such registration has counted as one of the permitted Demand Registrations.



<PAGE>

         (c) PRIORITY ON DEMAND REGISTRATIONS. If a Demand Registration is an
underwritten offering and the managing underwriters advise EDI in writing that
in their opinion the number of Registrable Securities and, if permitted
hereunder, other securities requested to be included in such offering exceeds
the number of Registrable Securities and other securities, if any, which can be
sold in an orderly manner in such offering within a price range acceptable to
HRL (or, if HRL is not participating in such offering, holders of a majority of
the Registrable Securities participating in such offering) without adversely
affecting the marketability of the offering, EDI shall include in such
registration prior to the inclusion of any securities which are not Registrable
Securities the number of Registrable Securities requested to be included which
in the opinion of such underwriters can be sold in an orderly manner within the
price range of such offering without adversely affecting the marketability of
the offering, pro rata among the respective holders thereof on the basis of the
amount of Registrable Securities owned by each such holder.

         (d) RESTRICTIONS ON DEMAND REGISTRATIONS. EDI shall not be obligated to
effect any Demand Registration within 180 days after the effective date of a
previous Demand Registration. EDI may postpone for up to 90 days the filing or
the effectiveness of a registration statement for a Demand Registration if EDI
and HRL (or, if HRL is not participating in such offering, holders of a majority
of the Registrable Securities participating in such offering) agree that such
Demand Registration would reasonably be expected to have a material adverse
effect on any proposal or plan by EDI to engage in any acquisition of assets
(other than in the ordinary course of business) or any merger, consolidation,
tender offer, reorganization or similar transaction; provided that in such
event, shall be entitled to withdraw such request and, if such request is
withdrawn, such Demand Registration shall not count as one of the permitted
Demand Registrations hereunder and EDI shall pay all Registration Expenses in
connection with such registration.

         (e) SELECTION OF UNDERWRITERS. The holders of a majority of the
Registrable Securities included in any Demand Registration shall have the right
to select the investment banker(s) and manager(s) to administer the offering,
subject to EDI's approval which shall not be unreasonably withheld or delayed.

2.       PIGGYBACK REGISTRATIONS.

         (a) RIGHT TO PIGGYBACK. Whenever EDI proposes to register any of its
securities under the Securities Act (other than pursuant to a Demand
Registration which shall be governed by Section 1 above) and the registration
form to be used may be used for the registration of Registrable Securities (a
"PIGGYBACK REGISTRATION"), EDI shall give prompt written notice (in any event
within three business days after its receipt of notice of any exercise of demand
registration rights other than under this Agreement) to all holders of
Registrable Securities of its intention to effect such a registration and,
subject to the terms of Sections 2(c) and 2(d) hereof, shall include in such
registration all Registrable Securities with respect to which EDI has received
written requests for inclusion therein within 20 days after the receipt of EDI's
notice.

         (b) PIGGYBACK EXPENSES. The Registration Expenses of the holders of
Registrable Securities shall be paid by EDI in all Piggyback Registrations.

         (c) PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback Registration is
an underwritten primary registration on behalf of EDI, and the managing
underwriters advise EDI in writing that in their opinion the number of
securities requested to be included in such registration exceeds the number

                                       2


<PAGE>

which can be sold in an orderly manner in such offering within a price range
acceptable to EDI, in such offering without adversely affecting the
marketability of the offering, EDI shall include in such registration (i) first,
the securities EDI proposes to sell, (ii) second, the Registrable Securities HRL
requested to be included in such registration, (iii) third, the Registrable
Securities requested to be included in such registration by other holders of
Registrable Securities, pro rata among the holders of such Registrable
Securities on the basis of the number of shares owned by each such holder, and
(iii) fourth, other securities requested to be included in such registration.

         (d) PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration is
an underwritten secondary registration on behalf of holders of EDI's securities,
and the managing underwriters advise EDI in writing that in their opinion the
number of securities requested to be included in such registration exceeds the
number which can be sold in an orderly manner in such offering within a price
range acceptable to the holders initially requesting such registration, in such
offering without adversely affecting the marketability of the offering, EDI
shall include in such registration (i) first, the securities requested to be
included therein by the holders requesting such registration, (ii) second, the
Registrable Securities HRL requested to be included in such registration, (iii)
third, the Registrable Securities requested to be included in such registration
by other holders of Registrable Securities, pro rata among the holders of such
Registrable Securities on the basis of the number of shares owned by each such
holder, and (iii) fourth, other securities requested to be included in such
registration.

         (e) SELECTION OF UNDERWRITERS. If any Piggyback Registration is an
underwritten offering, the selection of investment banker(s) and manager(s) for
the offering must be approved by the holders of a majority of the Registrable
Securities included in such Piggyback Registration. Such approval shall not be
unreasonably withheld or delayed.

3.       HOLDBACK AGREEMENTS.

         (a) HOLDBACK AGREEMENTS.

                  (i) Each holder of Registrable Securities shall not effect any
         public sale or distribution (including sales pursuant to Rule 144) of
         equity securities of EDI, or any securities convertible into or
         exchangeable or exercisable for such securities, during a period not to
         exceed the seven days prior to and the 90-day period (or 180-day period
         with respect to any initial public offering) beginning on the effective
         date of any underwritten Demand Registration or any underwritten
         Piggyback Registration in which Registrable Securities are included
         (except as part of such underwritten registration) or such lesser
         period made available to directors, officers or 85% stockholders of
         EDI, unless the underwriters managing the registered public offering
         otherwise agree.

                  (ii) EDI (i) shall not effect any public sale or distribution
         of its equity securities, or any securities convertible into or
         exchangeable or exercisable for such securities, during the seven days
         prior to and during the 90-day period (or 180-day period with respect
         to any initial public offering) beginning on the effective date of any
         underwritten Demand Registration or any underwritten Piggyback
         Registration (except as part of such underwritten registration or

                                       3


<PAGE>

         pursuant to registrations on Form S-8 or any successor form), unless
         the underwriters managing the registered public offering otherwise
         agree, and (ii) shall cause each holder of its Common Stock, or any
         securities convertible into or exchangeable or exercisable for Common
         Stock, purchased from EDI at any time after the date of this Agreement
         (other than in a registered public offering) to agree not to effect any
         public sale or distribution (including sales pursuant to Rule 144) of
         any such securities during such period (except as part of such
         underwritten registration, if otherwise permitted), unless the
         underwriters managing the registered public offering otherwise agree.

4.       REGISTRATION PROCEDURES.

         (a) Whenever the holders of Registrable Securities have requested that
any Registrable Securities be registered pursuant to this Agreement, EDI shall
use its best efforts to effect the registration and the sale of such Registrable
Securities in accordance with the intended method of disposition thereof and
pursuant thereto EDI shall as expeditiously as possible:

                  (i) prepare and file with the Securities and Exchange
         Commission a registration statement with respect to such Registrable
         Securities and use its best efforts to cause such registration
         statement to become effective (provided that before filing a
         registration statement or prospectus or any amendments or supplements
         thereto, EDI shall furnish to the counsel selected by the holders of a
         majority of the Registrable Securities covered by such registration
         statement copies of all such documents proposed to be filed, which
         documents shall be subject to the review and comment of such counsel);

                  (ii) notify each holder of Registrable Securities of the
         effectiveness of each registration statement filed hereunder and
         prepare and file with the Securities and Exchange Commission such
         amendments and supplements to such registration statement and the
         prospectus used in connection therewith as may be necessary to keep
         such registration statement effective for a period of not less than 180
         days and comply with the provisions of the Securities Act with respect
         to the disposition of all securities covered by such registration
         statement during such period in accordance with the intended methods of
         disposition by the sellers thereof set forth in such registration
         statement;

                  (iii) furnish to each seller of Registrable Securities such
         number of copies of such registration statement, each amendment and
         supplement thereto, the prospectus included in such registration
         statement (including each preliminary prospectus) and such other
         documents as such seller may reasonably request in order to facilitate
         the disposition of the Registrable Securities owned by such seller;

                  (iv) use its best efforts to register or qualify such
         Registrable Securities under such other securities or blue sky laws of
         such jurisdictions as any seller reasonably requests and do any and all
         other acts and things which may be reasonably necessary or advisable to
         enable such seller to consummate the disposition in such jurisdictions
         of the Registrable Securities owned by such seller (provided that EDI
         shall not be required to (i) qualify generally to do business in any
         jurisdiction where it would not otherwise be required to qualify but
         for this subSection, (ii) subject itself to taxation in any such
         jurisdiction or (iii) consent to general service of process in any such
         jurisdiction);

                                       4


<PAGE>

                  (v) notify each seller of such Registrable Securities, at any
         time when a prospectus relating thereto is required to be delivered
         under the Securities Act, of the happening of any event as a result of
         which the prospectus included in such registration statement contains
         an untrue statement of a material fact or omits any fact necessary to
         make the statements therein not misleading, and, at the request of any
         such seller, EDI shall prepare a supplement or amendment to such
         prospectus so that, as thereafter delivered to the purchasers of such
         Registrable Securities, such prospectus shall not contain an untrue
         statement of a material fact or omit to state any fact necessary to
         make the statements therein not misleading;

                  (vi) provide a transfer agent and registrar for all such
         Registrable Securities not later than the effective date of such
         registration statement;

                  (vii) enter into such customary agreements (including
         underwriting agreements in customary form) and take all such other
         actions as the holders of a majority of the Registrable Securities
         being sold or the underwriters, if any, reasonably request in order to
         expedite or facilitate the disposition of such Registrable Securities
         (including effecting a stock split or a combination of shares);

                  (viii) make available for inspection by any seller of
         Registrable Securities, any underwriter participating in any
         disposition pursuant to such registration statement and any attorney,
         accountant or other agent retained by any such seller or underwriter,
         all financial and other records, pertinent corporate documents and
         properties of EDI, and cause EDI's officers, directors, employees and
         independent accountants to supply all information reasonably requested
         by any such seller, underwriter, attorney, accountant or agent in
         connection with such registration statement; and

                  (ix) otherwise use its best efforts to comply with all
         applicable rules and regulations of the Securities and Exchange
         Commission, and make available to its security holders, as soon as
         reasonably practicable, an earnings statement covering the period of at
         least twelve months beginning with the first day of EDI's first full
         calendar quarter after the effective date of the registration
         statement, which earnings statement shall satisfy the provisions of
         Section 11(a) of the Securities Act and Rule 158 thereunder.

         (b) REGISTRATION EXPENSES.

                  (i) All expenses incident to EDI's performance of or
         compliance with this Agreement, including without limitation all
         registration and filing fees, fees and expenses of compliance with
         securities or blue sky laws, printing expenses, messenger and delivery
         expenses, fees and disbursements of custodians, and fees and
         disbursements of counsel for EDI and all independent certified public
         accountants, underwriters (excluding discounts and commissions) and
         other Persons retained by EDI (all such expenses being herein called
         "REGISTRATION EXPENSES"), shall be borne as provided in this Agreement,

                                       5


<PAGE>

         except that EDI shall, in any event, pay its internal expenses
         (including, without limitation, all salaries and expenses of its
         officers and employees performing legal or accounting duties), the
         expense of any annual audit or quarterly review, the expense of any
         liability insurance and the expenses and fees for listing the
         securities to be registered on each securities exchange on which
         similar securities issued by EDI are then listed or on the NASD
         automated quotation system.

                  (ii) In connection with each Demand Registration and each
         Piggyback Registration, EDI shall reimburse the holders of Registrable
         Securities included in such registration for the reasonable fees and
         expenses and disbursements of one counsel chosen by the holders of a
         majority of the Registrable Securities included in such registration.

                  (iii) To the extent Registration Expenses are not required to
         be paid by EDI, each holder of securities included in any registration
         hereunder shall pay those Registration Expenses allocable to the
         registration of such holder's securities so included, and any
         Registration Expenses not so allocable shall be borne by all sellers of
         securities included in such registration in proportion to the aggregate
         selling price of the securities to be so registered.

         (c) INDEMNIFICATION.

                  (i) EDI agrees to indemnify, to the extent permitted by law,
         each holder of Registrable Securities, its officers and directors and
         each Person who controls such holder (within the meaning of the
         Securities Act) against all losses, claims, damages, liabilities and
         expenses caused by any untrue or alleged untrue statement of material
         fact contained in any registration statement, prospectus or preliminary
         prospectus or any amendment thereof or supplement thereto or any
         omission or alleged omission of a material fact required to be stated
         therein or necessary to make the statements therein not misleading,
         except insofar as the same are caused by or contained in any
         information furnished in writing to EDI by such holder expressly for
         use therein or by such holder's failure to deliver a copy of the
         registration statement or prospectus or any amendments or supplements
         thereto after EDI has furnished such holder with a sufficient number of
         copies of the same. In connection with an underwritten offering, EDI
         shall indemnify such underwriters, their officers and directors and
         each Person who controls such underwriters (within the meaning of the
         Securities Act) to the same extent as provided above with respect to
         the indemnification of the holders of Registrable Securities.

                  (ii) In connection with any registration statement in which a
         holder of Registrable Securities is participating, each such holder
         shall furnish to EDI in writing such information and affidavits as EDI
         reasonably requests for use in connection with any such registration
         statement or prospectus and, to the extent permitted by law, shall
         indemnify EDI, its directors and officers and each Person who controls
         EDI (within the meaning of the Securities Act) against any losses,
         claims, damages, liabilities and expenses resulting from any untrue or
         alleged untrue statement of material fact contained in the registration

                                       6


<PAGE>

         statement, prospectus or preliminary prospectus or any amendment
         thereof or supplement thereto or any omission or alleged omission of a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, but only to the extent that such
         untrue statement or omission is contained in any information or
         affidavit so furnished in writing by such holder; provided that the
         obligation to indemnify shall be individual, not joint and several, for
         each holder and shall be limited to the net amount of proceeds received
         by such holder from the sale of Registrable Securities pursuant to such
         registration statement.

                  (iii) Any Person entitled to indemnification hereunder shall
         (i) give prompt written notice to the indemnifying Party of any claim
         with respect to which it seeks indemnification (provided that the
         failure to give prompt notice shall not impair any Person's right to
         indemnification hereunder to the extent such failure has not prejudiced
         the indemnifying Party) and (ii) unless in such indemnified Party's
         reasonable judgment a conflict of interest between such indemnified and
         indemnifying Parties may exist with respect to such claim, permit such
         indemnifying Party to assume the defense of such claim with counsel
         reasonably satisfactory to the indemnified Party. If such defense is
         assumed, the indemnifying Party shall not be subject to any liability
         for any settlement made by the indemnified Party without its consent
         (but such consent shall not be unreasonably withheld). An indemnifying
         Party who is not entitled to, or elects not to, assume the defense of a
         claim shall not be obligated to pay the fees and expenses of more than
         one counsel for all Parties indemnified by such indemnifying Party with
         respect to such claim, unless in the reasonable judgment of any
         indemnified Party a conflict of interest may exist between such
         indemnified Party and any other of such indemnified Parties with
         respect to such claim.

                  (iv) The indemnification provided for under this Agreement
         shall remain in full force and effect regardless of any investigation
         made by or on behalf of the indemnified Party or any officer, director
         or controlling Person of such indemnified Party and shall survive the
         transfer of securities. EDI also agrees to make such provisions, as are
         reasonably requested by any indemnified Party, for contribution to such
         Party in the event EDI's indemnification is unavailable for any reason.

         (d) PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Person may
participate in any registration hereunder which is underwritten unless such
Person (i) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Person or Persons entitled hereunder
to approve such arrangements and (ii) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
required under the terms of such underwriting arrangements; PROVIDED THAT no
holder of Registrable Securities included in any underwritten registration shall
be required to make any representations or warranties to EDI or the underwriters
(other than representations and warranties regarding such holder and such
holder's intended method of distribution) or to undertake any indemnification
obligations to EDI or the underwriters with respect thereto, except as otherwise
provided in Section 4.3 hereof.

exercise all other rights granted by law. The Parties hereto agree and
acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that, in addition to any other rights and
remedies existing in its favor, any Party shall be entitled to specific
performance and/or other injunctive relief from any court of law or equity of
competent jurisdiction (without posting any bond or other security) in order to
enforce or prevent violation of the provisions of this Agreement.

         (d) AMENDMENTS AND WAIVERS. Except as otherwise provided herein, the
provisions of this Agreement may be amended or waived only upon the prior
written consent of EDI and HRL.

         (e) SUCCESSORS AND ASSIGNS. All covenants and agreements in this
Agreement by or on behalf of any of the Parties hereto shall bind and inure to
the benefit of the respective successors and assigns of the Parties hereto
whether so expressed or not. In addition, whether or not any express assignment
has been made, the provisions of this Agreement which are for the benefit of
purchasers or holders of Registrable Securities are also for the benefit of, and
enforceable by, HRAI, HRL's owner and any subsequent holder of Registrable
Securities.

         (f) SEVERABILITY. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision shall be ineffective only to
the extent of such prohibition or invalidity, without invalidating the remainder
of this Agreement.

         (g) DESCRIPTIVE HEADINGS. The descriptive headings of this Agreement
are inserted for convenience only and do not constitute a part of this
Agreement.

         (h) GOVERNING LAW. All issues and questions concerning the
construction, validity, interpretation and enforcement of this Agreement and the
exhibits and schedules hereto shall be governed by, and construed in accordance
with, the laws of the State of California, without giving effect to any choice
of law or conflict of law rules or provisions (whether of the State of
California or any other jurisdiction) that would cause the application of the
laws of any jurisdiction other than the State of California. In furtherance of
the foregoing, the internal law of the State of California shall control the
interpretation and construction of this Agreement (and all schedules and
exhibits hereto), even though under that jurisdiction's choice of law or
conflict of law analysis, the substantive law of some other jurisdiction would
ordinarily apply.

         (i) NOTICES. All notices, demands or other communications to be given
or delivered under or by reason of the provisions of this Agreement shall be in

                                   APPENDIX I

         If the holders of Registrable Securities request a Demand Registration,
EDI may avoid such registration if all of the following conditions are met:

         A. either (i) EDI has Common Stock registered pursuant to Section 12 of
the Securities Exchange Act, has been subject to the reporting requirements of
Section 13 of the Securities Exchange Act for a period of at least 90 days
immediately preceding the proposed sale of the Registrable Securities and has
filed all reports required to be filed thereunder during the 12 months preceding
such proposed sale (or for such shorter period that EDI has been required to
file such reports) or (ii) EDI has Common Stock registered pursuant to the
Securities Act, has been subject to the reporting requirements of Section 15(d)
of the Securities Exchange Act for a period of at least 90 days immediately
preceding the proposed sale of the Registrable Securities and has filed all
reports required to be filed thereunder during the 12 months preceding such
proposed sale (or for such shorter period that EDI has been required to file
such reports),

         B. counsel for EDI delivers an opinion, satisfactory to a majority of
the holders of Registrable Securities requesting such registration and such
holders' underwriter, broker, dealer, market maker or agent ("Underwriter"), to
the effect that (i) the sale of such securities does not require registration
pursuant to the Securities Act and (ii) the sale of such shares may be effected
without any restrictions on the amount or manner of such sale,

         C. EDI delivers to the selling holder a prospectus or selling document,
satisfactory to a majority of the holders of Registrable Securities and such
holders' Underwriter, to enable such holders to sell their Registrable
Securities,

         D. EDI pays the expenses incurred in preparing the printing of such
prospectus or selling document, the fees and expenses of compliance with
applicable blue sky or state securities laws, the fees and disbursements of
counsel for EDI and all independent certified public accountants and other
Persons retained by EDI, the fees and disbursements of one counsel for the
selling holders, EDI's internal expenses and fees for listing the securities to
be sold on each securities exchange on which similar securities issued by EDI
are then listed and all expenses of the Underwriter (excluding discounts and
commissions), and

         E. such holders receive an opinion from the Underwriter that, despite
the lack of registration under the Securities Act, the sale of such securities
may be effected without (i) any decrease in the price received for such
securities, (ii) any increase in the discount or commission of the Underwriter
or (iii) any decrease in the amount of securities which the Underwriter believes
can practically be sold.

If an offering of Registrable Securities occurs pursuant to this Appendix I, the
provisions of Sections 1.4, 3, 4.1(d) through 4.1(i), 4.2(c), 4.3 and 4.4 shall
apply to such offering as if it were an offering registered by EDI with the
Securities and Exchange Commission.
