   This Proxy Statement is furnished to the shareholders of
Mentor Corporation (the "Company"), in connection with the
solicitation by the Company's Board of Directors of the enclosed
proxy for use at the Annual Meeting of Shareholders to be held
Wednesday, September 16, 1998, at 10:00 a.m. (Central Daylight
Time) at the Minneapolis Hilton and Towers, 1001 Marquette
Avenue, Minneapolis, Minnesota, or at any adjournments or

Common Stock represented by proxies in the form solicited will
be voted in accordance with the instructions indicated therein,
but proxies may be revoked at any time before being exercised by
delivery to the Secretary of the Company of a written notice of
revocation of the proxy's authority or a duly executed proxy
bearing a later date.  You may also revoke your proxy by
attending the Annual Meeting and voting in person.  A
shareholder who attends the Annual Meeting need not revoke his
or her proxy and vote in person, unless he or she wishes to do
so.

   Expenses in connection with the solicitation of proxies will
be paid by the Company.  Proxies are being solicited primarily
by mail, but, in addition, directors, officers and regular
employees of the Company may solicit proxies personally, by
telephone or by special letter.

   So far as the management of the Company is aware, no matters
other than those described in this Proxy Statement will be acted
upon at the meeting.  In the event that any other matters
calling for a vote of shareholders properly come before the
Annual Meeting, the persons named as proxies in the enclosed
form of proxy will vote in accordance with their judgment on
such other matters.

   The Annual Report of the Company, including financial
statements, for the fiscal year ended March 31, 1998 is being
furnished to each shareholder with this Proxy Statement.

   The principal executive offices of the Company are located at
5425 Hollister Avenue, Santa Barbara, California  93111.  The
approximate mailing date of this Proxy Statement and the
accompanying form of proxy is August 12, 1998.

          RECORD DATE, QUORUM AND VOTING OF SECURITIES

   The Common Stock of the Company, par value $.10 per share, is
the only authorized voting security of the Company.  Only the
holders of the Company's Common Stock whose names appear of
record on the Company's books on July 20, 1998 will be entitled
to notice of, and to vote at, the 1998 Annual Meeting.  At the
close of business on July 20, 1998, a total of 25,111,789 shares
of Common Stock were outstanding, each entitled to one vote.
Holders of Common Stock do not have cumulative voting rights.
The presence in person or by proxy of the holders of a majority
of the outstanding shares of Common Stock will constitute a
quorum for the transaction of business at the Annual Meeting.
Abstentions and broker non-votes are each included in the number
of shares present for quorum purposes.  All votes will be
tabulated by the inspector of election appointed for the
meeting, who will separately tabulate affirmative and negative
votes, abstentions and broker non-votes.  Abstentions, which may
be specified on all proposals other than the election of
directors, are counted in tabulations of the votes cast on
proposals presented to shareholders and will have the same
effect as negative votes; whereas broker non-votes are not
counted for purposes of determining whether a proposal has been
approved.  An affirmative vote of a majority of the shares
present and voting at the meeting is required for approval of
all items being submitted to the shareholders for their
consideration.

          DEADLINE FOR RECEIPT OF SHAREHOLDER PROPOSALS

   Proposals of shareholders of the Company that are intended to
be presented by such stockholders at the Company's 1999 Annual
Meeting must be received no later than April 1, 1999, in order
that they may be included in the proxy statement and form of
proxy relating to that meeting.

           MATTERS TO BE CONSIDERED AT ANNUAL MEETING
                                
         PROPOSAL 1:  DESIGNATION OF NUMBER OF DIRECTORS

   The Company's By-Laws provide that the Board of Directors
must consist of not less than three directors, with the number
to be determined by a resolution of the shareholders.  Currently
the Board of Directors consists of seven (7) directors.  The
Board of Directors has recommended that the number of directors
constituting the Board of Directors for the ensuing year be
fixed at six (6).

   APPROVAL OF THIS PROPOSAL 1 IS A CONDITION TO THE ELECTION OF
THE DIRECTORS SET FORTH IN PROPOSAL 2 BELOW.  FAILURE OF THE
SHAREHOLDERS TO APPROVE THIS PROPOSAL 1 AT THE ANNUAL MEETING
WILL RESULT IN EACH OF THE CURRENT DIRECTORS HOLDING OFFICE
UNTIL HIS SUCCESSOR HAS BEEN ELECTED AND QUALIFIED.

   If proxies representing sufficient votes to approve Proposal
1 have not been received by the scheduled date of the Annual
Meeting, the chairman of the Annual Meeting may adjourn the
Annual Meeting to a later date and time, or the individuals
named as proxies may vote to so adjourn the Annual Meeting, for
the purpose of soliciting additional proxies.

   The Board of Directors recommends that the shareholders vote
FOR Proposal 1, fixing at six (6)  the number of directors on
the Board of Directors.


               PROPOSAL 2:  ELECTION OF DIRECTORS

   Provided that the shareholders approve Proposal 1, six
directors are to be elected at the Annual Meeting.  Unless
specifically directed otherwise, it is the intention of the
proxy holders named in the enclosed proxy to vote such proxies
for the six nominees first named below, all of which are
currently directors, to hold office until the 1999 Annual
Meeting of Directors and until their successors are elected and
qualified.

   There are currently seven directors on the Company's Board of
Directors.  Byron Shaffer is not standing for re-election.

   Each nominee has indicated a willingness to serve, but in
case any nominee is not a candidate at the meeting, for reasons
not now known to the Company, the proxies named in the enclosed
form of proxy may vote for a substitute nominee in their
discretion.  Information regarding these nominees is set forth
in the table below.

Board Meetings and Committees

     During the fiscal year ended March 31, 1998, the Board of
Directors met or adopted resolutions by unanimous written
consent on 12 occasions.  No director attended less than 75% of
the aggregate number of Board of Directors meetings and meetings
of committees on which he served (including actions taken by
written consent).

     The Company has an Audit Committee, currently consisting of
Messrs. Faster, Glover, Nakonechny, Shaffer and Young.  The
principal functions of the audit committee are to (i) recommend
to the Board of Directors the independent public accountants to
act as the Company's independent auditors; (ii) discuss with the
independent auditors the scope of their audit; (iii) discuss
with the independent auditors and the Company's executive
officers the Company's accounting principles, policies and
practices; (iv) discuss with the independent auditors the
adequacy of the Company's accounting, financial and operating
controls, and (v) approve the internal audit department annual
audit schedule and review with the internal audit department the
results and recommendations of those audits.

     The Audit Committee has adopted procedures providing for
its prior review and consideration of the effect of non-audit
services on the independence of Ernst & Young LLP and the
approval of the types of, and estimated fees for, professional
services which are expected to be performed by Ernst & Young LLP
during the forthcoming fiscal year.

     The Audit Committee met once during the fiscal year ended
March 31, 1998 with all committee members present.

     The Company has a standing Compensation Committee,
currently consisting of Messrs. Faster, Glover, Nakonechny,

to administer the Company's stock option plans.  The Stock
Option Committee met twice during the fiscal year ended March
31, 1998 with all members present.

Nominating Procedures

     The Company does not have a separately constituted
committee to nominate candidates for election to the Board of
Directors of the Company.  Such candidates are chosen by the
existing Board after taking into consideration the
recommendations of the Company's executive officers and
shareholders.  Shareholders wishing to submit recommendations
for nomination should send them in writing to the attention of
the Company's Chairman at the Company's principal executive
office within sixty days after the end of the Company's fiscal
year.

Compensation of Directors

     Board members who are employees of the Company do not
receive compensation for their services as directors.  During
the Company's fiscal year ended March 31, 1998 and currently,
individual non-employee Board members received an annual fee of
$20,000.  In addition, each person who is a non-employee
director on the date of an annual meeting of shareholders is
entitled to receive an automatic option grant under the
Company's 1991 Stock Option Plan (the "Option Plan") of options
to purchase 6,000 shares of Common Stock at an exercise price
equal to the fair market value per share of the Common Stock on
the date of such grant.  These options have a term of ten years
and become exercisable in four equal annual installments over
the optionee's period of Board service, beginning one year after
the grant date.  Under the Option Plan, each person who is newly
elected or appointed as a non-employee director will receive, on
the date of election or appointment, an automatic option grant
to purchase 20,000 shares of Common Stock.  The maximum number
of shares of Common Stock that a non-employee director currently
may receive under the Option Plan is 60,000, plus 60,000 to the
extent the non-employee director received options to purchase
30,000 shares on May 17, 1994 and 30,000 shares on May 15, 1997,
less the number of shares granted to the director under any
prior option plan of the Company, taking into account adjustment
for the Company's 2 for 1 stock split effectuated in September
1995.  Currently, all non-employee directors have received such
maximum number of shares.

        PROPOSAL 3:  RATIFICATION OF INDEPENDENT AUDITORS

   Pursuant to authority delegated to the Audit Committee by the
Board of Directors, the Audit Committee has appointed the firm
of Ernst & Young LLP to act as principal independent auditors
for the Company for the fiscal year ending March 31, 1999.  This
appointment will be submitted to the Company's shareholders for
ratification.  This firm has audited the financial statements of
the Company for the fiscal year ended March, 31, 1998, and for
prior years, and has advised the Company that neither the firm
nor any of its partners has any direct or indirect material
financial interests in the Company or its subsidiaries, nor have
they had any connection during the past three years with the
Company or its subsidiaries, in any capacity other than that of
independent accountants and auditors.  Ernst & Young LLP will
have representatives at the 1998 Annual Meeting who will have an
opportunity to make a statement and will be available to respond
to appropriate questions.

   In the event the shareholders do not ratify the appointment
of Ernst & Young LLP, the selection of other independent
auditors will be considered by the Board of Directors.

   The Board of Directors recommends that shareholders vote FOR
ratification of the appointment of Ernst & Young LLP to serve as
the Company's independent auditors for the fiscal year ending
March 31, 1999.


                          OTHER MATTERS

     The Company knows of no other matters that will be
presented for consideration at the Annual Meeting.  If any other
matters properly come before the Annual Meeting, it is the
intention of the persons named in the enclosed form of Proxy to
vote the shares they represent as the Board of Directors may
recommend.  Discretionary authority with respect to such other
matters is granted by the execution of the enclosed Proxy.

(1)  All of these options were granted under the 1991 Stock Option Plan on May
     15, 1997.  Each option will become exercisable for the option shares in
     four equal and successive annual installments over the optionee's period of
     service with the Company, beginning one year after the grant date.  Each
     option has a maximum term of ten years, subject to earlier termination
     immediately prior to a Change in Control (as defined in the 1991 Stock
     Option Plan); alternatively, the administrator of the 1991 Stock Option
     Plan may provide for replacement of outstanding options with options to
     purchase shares of the surviving corporation, or for a cash payment in
     exchange for the cancellation of outstanding options.

(2)  The exercise price of each option is equal to the market value of the
     Common Stock on the date of grant.  The exercise price may be paid in cash,
     in Common Stock or pursuant to a cashless exercise procedure under which
     the optionee provides irrevocable instructions to a brokerage firm to sell
     the purchased shares and to remit to the Company, out of the sale proceeds,
     an amount equal to the exercise price plus all applicable withholding
     taxes.  The administrator of the 1991 Stock Option Plan may authorize a
     loan or loan guarantee from the Company to help the optionee pay the
     exercise price or the administrator may permit the optionee to pay the
     option price in installments.

(3)  Potential realizable value is based on an assumption that the market price
     of the stock appreciates at the stated rate, compounded annually, from the
     date of grant until the end of the ten year option term.  These values are
     calculated based on regulations promulgated by the Securities and Exchange
     Commission and do not reflect the Company's estimate of future stock price
     appreciation.  There is no assurance that the actual stock price
     appreciation over the ten year option term will be at the assumed 5% or 10%
     levels, or at any other defined level.

     Common Stock which is lower than the fair market value of the Common Stock
     on a specified date.  The fair market value of the Company's Common Stock
     at March 31, 1998 was $27.63 per share.


Employment Contracts and Severance Arrangements

   The Company has entered into an Employment Agreement with
Malcolm Boddy, the President of Mentor Manufacturing Operations
Division. The agreement provided for Mr. Boddy to receive in
fiscal 1998 (i) a base salary of $200,000, prorated from the
date of employment, (ii) a bonus of up to 40% of such base
salary based on attainment of mutually designated objectives,
(iii) options to purchase 25,000 shares of Common Stock, with a
vesting period of five years, and (iv) a relocation package to
defray his costs of moving to Santa Barbara, California.
Beginning in fiscal 1999, Mr. Boddy's compensation is fixed
annually by the Compensation Committee. The agreement also
provides that upon termination of Mr. Boddy's employment by the
Company without cause (as defined therein), Mr. Boddy will be
entitled to severance compensation equal to three months of base
salary plus one month of base salary for each complete year of
service with the Company.


     COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

   The Company's Compensation Committee (the "Committee") was
established in 1980 and is composed entirely of independent,
outside members of the Company's Board of Directors.  The
Committee reviews and approves each of the elements of the
executive compensation program and assesses the effectiveness
and competitiveness of the overall program.

   Mentor's executive compensation program is designed to
accomplish several goals, including:

- -To attract, retain, and motivate employees of outstanding ability
- -To link changes in employee compensation to individual and
corporate performance
- -To align the interests of management with the interests of the
Company's shareholders
- -To provide levels of compensation that are competitive with
those provided in the markets in which the Company competes for
executives.

Key Provisions of the Executive Compensation Program

   The Company's executive compensation plan consists of three
components:  base salary, annual incentive bonus, and long-term
incentive in the form of stock options.  The Company has
established a strong link between pay and performance by
emphasizing variable components of the plan, that is, annual
incentive bonus and stock options.

Base Salary

   The Committee determines base salaries for executive officers
on the basis of a number of factors, including an assessment of
competitive compensation levels for similar-size manufacturing
companies performed by an independent consulting firm, the
Company's financial condition, any changes in job
responsibilities, and the performance of each executive.
Executive officer base salaries generally are set to correspond
to the 60th percentile of the comparable competitive
compensation data.

Annual Incentive Bonus

   Executive officers are eligible to receive annual incentive
compensation equivalent to a specified percentage of their
salaries under the Company's bonus plan.  The Company
establishes bonus payout targets (ranging from 30% to 60% of
base salary) that are designed to bring the level of total
annual cash compensation (base salary plus annual incentive
bonus) to the 75th percentile for comparable positions at
similar-size manufacturing companies when superior performance
is achieved.  Performance is measured at the corporate, business
unit, and individual level.  The total potential bonus for each
executive is broken down into several factors as appropriate for
that executive's area of responsibility.  Each factor is then
weighted with emphasis placed on profitability measures.  These
factors, and the relative weight given to each factor, vary with
each executive officer in the Committee's sole discretion.  For
each factor, the Committee establishes a threshold, target and
outstanding goal.  No bonus is paid for performance below
threshold levels.  Bonuses for threshold performance are paid at
50% of the targeted levels.  Bonuses for outstanding performance
are paid at 200% of targeted levels for the Chief Executive
Officer and President, and 150% of targeted levels for all other
executive officers. The total bonus paid each executive is thus
a weighted average of each factor, adjusted for performance
against a predefined target for that factor.

Long-term Incentive (Stock Options)

   Generally, the Company awards stock options to executive
officers on an annual basis.  Each grant is designed to align
the interests of executive officer with those of the
shareholders and provide each individual with a significant
incentive to manage the Company from the perspective of an owner
with an equity stake in the business.  Awards to specific
employees, including the Chief Executive Officer, are made on
the basis of each employee's job responsibilities and
recommendations of the executive officers of the Company
concerning the individual's contributions (both historical and
potential) to the success of the Company, without regard to
prior awards of stock option grants.  These recommendations also
take into consideration competitive practice for stock option
grants as determined by an independent compensation consultant
from survey information.  The survey information encompasses
data on both competitive grant levels for individual executives
and total options granted as a percentage of shares outstanding.

Compensation of Chief Executive Officer

   Mr. Conway is a founder of the Company and has served as its
Chief Executive Officer and Chairman of the Board since its
incorporation in 1969. Mr. Conway's base salary and annual
incentive bonus are set by the Committee using the same policies
and criteria used for other executive officers.  In setting Mr.
Conway's salary for fiscal 1998, the Committee considered
competitive information for similar sized manufacturing
companies provided by an independent compensation consultant and
the Company's financial performance.  Mr. Conway is currently
paid at the targeted competitive position base salary, which has
been set by the Committee at the 60th percentile of the
comparable competitive compensation data.

   Mr. Conway's bonus potential is designed to bring his total
annual cash compensation to the 75th percentile for comparable
positions at similar sized manufacturing companies.  For Mr.
Conway, this targeted bonus equated to 60% of his base salary in
fiscal 1998.  Mr. Conway's fiscal 1998 bonus was based on the
achievement of two separate corporate goals:  net sales
(weighted 30%) and corporate profitability (weighted 70%).  The
compensation plan for fiscal 1998 was designed to encourage
aggressive operating profit growth over the prior year. The
Company performed below its threshold performance level in
fiscal 1998. As a result, Mr. Conway received no bonus in fiscal
1998.

Tax Limitation

   As a result of federal tax legislation enacted in 1993, a
publicly-held company such as the Company will not be allowed a
federal income tax deduction for compensation paid to certain
executive officers, to the extent that compensation exceeds $1
million per officer in any year.  It is not expected that the
compensation to be paid to the Company's executive officers for
the 1999 fiscal year will exceed the $1 million limit per
officer. Compensation which qualifies as performance-based
compensation will not have to be taken into account for purposes
of this limitation.  At the 1994 Annual Meeting, the Company
obtained shareholder approval for certain amendments to the
Company's Option Plan which were designed to assure that any
compensation deemed paid in connection with the exercise of
stock options granted under that plan will qualify as
performance-based compensation. As a result, the Company
believes that stock options granted to its executives qualify
for the performance-based exception to the deduction limit.
However, there can be no assurance that the options will so
qualify. In addition, future amendments to the Company's Option
Plan may be necessary to preserve such qualification in the
future.

   The cash compensation paid to the Company's executive
officers for the fiscal 1998 year did not exceed the $1 million
limit per officer, nor is the cash compensation to be paid to
the Company's executive officers for the 1999 fiscal year
expected to reach that level.  Because it is very unlikely that
the cash compensation payable to any of the Company's executive
officers in the foreseeable future will approach the $1 million
limitation, the Compensation Committee has decided not to take
action at this time to limit or restructure the elements of cash
compensation payable to the Company's executive officers.  The
Compensation Committee will reconsider this decision should the
individual compensation of any executive officer ever approach
the $1 million level.

equity securities of the Company.  Officers, directors and
greater than ten-percent shareholders are required by SEC
regulation to furnish the Company with copies of all Section
16(a) forms they file.

     To the Company's knowledge, based solely on review of the

representations that no other reports were required, during the
fiscal year ended March 31, 1998, all Section 16(a) filing
requirements applicable to its officers, directors and greater
than ten-percent beneficial owners were complied with, except
that, due to an administrative error, Mr. Purkait filed a Form 4
