Anthony C. Vickerson, Secretary                   Robert M. Long, ChairmanOctober 9, 2000

Mr. Carl E. Sassano
42 Sunrise Park
Pittsford, NY  14534

Dear Carl:

The purpose of this letter is to summarize the terms and
conditions of your separation of employment from Bausch & Lomb
Incorporated ("Bausch & Lomb" or "the Company") and your
resignation as an officer of the Company.

1.   You will be considered a full time active employee through
     October 31, 2000, at which point your position will have been
     eliminated and you will have resigned as an officer of the
     Company. We are confirming that between the date of notice of
     your separation (August 23, 2000) and October 31, 2000, we
     advised you it would not be necessary for you to report to work.
     However, during the remainder of this period, you will be
     required to make yourself available on an as-needed basis to
     assist in transitioning your duties, as directed by the Chairman
     and Chief Executive Officer. Starting November 1, 2000, we have
     agreed that you will take a three (3) month leave of absence
     without pay, which leave of absence will end on January 31, 2001.
     At that point, you will have accrued your five weeks of 2001 paid
     vacation, which you will take beginning February 1, 2001 and
     ending on March 7, 2001 ("Separation Date"). Beginning the day
     after the Separation Date, your status will be changed to that of
     an inactive employee, subject to the terms and conditions hereof,
     and Bausch & Lomb will pay you an amount equal to your current
     monthly base salary each month for twenty-four (24) consecutive
     months (the "Severance Period"). As you are aware, this amount
     is twice that provided for in the Officer Separation Plan.
     During this period, you will continue to receive those current
     benefits and perquisites detailed below.  Additionally, although
     you will receive a lump sum payment for your unused 2000 vacation
     time, if any, you will not accrue or be paid for vacation time
     during the Severance Period.

2.   Officer perquisites will continue as follows:

     A. Company Car. You may purchase your company car by May 1,
        2001 for a reasonable depreciated value determined by Bausch &
        Lomb. If not purchased, the car must be returned to Bausch &
        Lomb by May 1, 2001.

     B. Financial Counseling. Bausch & Lomb will continue to
        reimburse you for reasonable financial planning expenses through
        October 31, 2002 in an amount up to two (2) percent of your base
        salary, which may include legal services sought in connection
        with the negotiation and finalization of this letter.

     C. Other. Bausch & Lomb will continue to reimburse or pay
        existing regular dues associated with a country, social, luncheon
        or airline club through October 31, 2002.

3.   During the unpaid leave of absence, you will not be
     considered an active employee. However, you will continue to
     receive your current medical, dental and life insurance benefits
     at active employee rates and the premiums will be deducted from
     your first paycheck after the leave of absence ends. While using
     your vacation time in 2001, you will continue to receive medical,
     dental and life insurance coverage at the then-current active
     employee rates, which amounts shall continue to be deducted from
     your paychecks. In addition, during the Severance Period, you
     may elect to continue your medical, dental and life insurance at
     the then-current active employee rates. At the end of the
     Severance Period, you will be eligible for COBRA coverage that
     allows you to continue your current medical and dental insurance
     at the full premium rates for up to an additional 18 months. At
     the end of the Severance Period, you will qualify to receive
     medical coverage, but not retiree dental or life insurance, under
     the Company's retiree medical insurance plan once you reach the
     age of 55. This coverage will not be available to you if other
     coverage is available to you under another employer's plan or
     through a spouse's plan when you turn 55.  You will need to
     contact Corporate Benefits to apply for this coverage.

4.   There is no COBRA eligibility for life insurance. However,
     within 31 days following the end of your Severance Period, you
     may elect (without providing evidence of insurability) an Aetna
     conversion policy to replace some or all of your coverage.

5.   Disability coverage ceases on October 31, 2000. There are
     limited conversion rights for long term disability. Upon your
     request, HR will provide you with more information.

6.   You are fully vested in the Bausch & Lomb Retirement Plan
     and the Supplemental Executive Retirement Plan III.
     Participation in the plans continues during the Severance Period
     and you retain through this Period the full rights and privileges
     under the plans you would have as an active employee (e.g., your
     participation continues, and benefit accruals continue). Within
     three (3) months of the end of your active plan participation,
     you will receive details on pension options from our Corporate
     Benefits Department.

7.   Participation in the Bausch & Lomb 401(k) plan continues
     during the Severance Period and you retain through this period
     the full rights and privileges under the plan you would have as
     an active employee (e.g. as applicable, you may continue
     contributing, associated Company matching contributions continue
     to be deposited on your behalf, etc.).  At the end of your active
     plan participation, you may leave your money in the Bausch & Lomb
     401(k) Plan or elect a distribution.  Contact InfoExpress at 1-
     800-479-0557 for account information or to make any future
     transactions.

8.   You may have elected to receive distribution from the Bausch
     & Lomb Deferred Compensation Plan under the terms of that Plan.
     The investment mix can be changed at any time prior to payout by
     completing the attached form and returning it to Corporate
     Compensation. You will continue to receive quarterly statements.
     Please advise Corporate Compensation (Cheryl Cody) of any address
     changes.

9.   As a participant in the Stock Option Plan, you have ninety
     (90) days from the end of the Severance Period to exercise vested
     stock options granted on or after January 27, 1997. For vested
     stock options granted prior to January 27, 1997, you have ninety
     (90) days from the Separation Date in which to exercise these
     options. If, prior to the expiration of the ninety (90) day post
     Separation Date exercise period available to you to exercise your
     pre-January 1997 vested stock options, the Company extends the
     exercise period for vested stock options granted prior to January
     27, 1997 for any or all employees participating in the Stock
     Option Plan, the Company will provide the benefit of the same
     extension to you. As of October 31, 2000, you will not be
     eligible for any future vesting in stock options or restricted
     stock, nor will you be eligible for company loans in connection
     with the exercise of vested or restricted options. Any
     outstanding stock option loans must be repaid within ninety (90)
     days of the end of the Severance Period. A listing of your
     options is attached.

10.  You will be eligible for an EVA bonus, prorated and
     attributable to the months of service performed through October
     31, 2000, payable in early 2001, as soon as practicable after EVA
     bonuses are approved by the Committee on Management of the Board
     of Directors, based on the actual performance of Bausch & Lomb.
     Pursuant to the terms of the EVA Plan, you will also receive any
     remaining amounts contained in the bank from prior years. You
     will not vest in Cycle I or in any additional Cycles under the
     Cumulative EVA Long Term Incentive Plan.

11.  Bausch & Lomb will assist you in your search for new
     employment by providing you with outplacement services in
     accordance with the Officer Separation Plan. You will be provided
     the names of two approved service providers from which you may
     choose the one you prefer. In the alternative, you may propose
     your own outplacement service provider, which will be subject to
     Bausch & Lomb's reasonable approval. Payment for outplacement
     services will be made directly by Bausch & Lomb.

12.  Bausch & Lomb will provide you with a reference letter in
     the form attached to this letter.

13.  In consideration of the benefits to be provided to you and
     as part of your fiduciary obligations to Bausch & Lomb, you agree
     that for a period of two (2) years from the Separation Date, you
     will not, directly or indirectly, (a) compete with any business
     in which Bausch & Lomb or any of its affiliates is currently
     engaged or actively developing, including working or consulting
     with Visualplex, (b) solicit any person who is a customer of a
     business conducted by Bausch & Lomb to be a customer of a similar
     business other than a business conducted by Bausch & Lomb or any
     of its affiliates, or (c) induce or attempt to persuade any
     employee of Bausch & Lomb or any of its affiliates to terminate
     his or her employment relationship with Bausch & Lomb or any of
     its affiliates. For purposes of this Agreement, the phrase
     "compete" shall include serving as an employee, an officer, a
     director, an owner, a partner or a five percent (5%) or more
     shareholder of any such business or otherwise engaging in or
     assisting another to engage in any such business. Without
     limiting the foregoing, Bausch & Lomb may consider, on an as
     requested basis, modifications to your restrictions on
     competition where management of Bausch & Lomb believes the
     competitive impact on Bausch & Lomb to be minimal or otherwise
     manageable. Notwithstanding the above, you shall be permitted
     to:

          A.  Engage in a retail business, provided such
     business is not owned or operated by or on behalf of a
     company which you would be prevented from working for
     or affiliating with under the preceding non-competition
     clause ("Competitor");

          B.  Provide consulting services to Bausch & Lomb
     customers regarding the customers' business, including,
     but not limited to, purchase/sales of businesses,
     strategic planning, expansion strategies, and the like,
     so long as such services are not being sought by or
     ultimately provided on behalf of a Competitor of Bausch
     & Lomb;

          C.  Engage in development and/or marketing of
     practice management services and software in the
     ophthalmic industry, so long as such services are not
     being sought by or ultimately provided on behalf of a
     Competitor of Bausch & Lomb;

          E.  Offering employment to Lisa Dean.

14.  You understand that you should consult with your attorney
     prior to the execution of this Agreement, and have been given a
     reasonable opportunity to do so.  You acknowledge that you
     understand the contents of this Agreement, and this Agreement is
     entered into freely and voluntarily, and that it is not
     predicated on or influenced by any representations of Bausch &
     Lomb or any of its employees.

15.  By accepting the package set forth in this Agreement, and
     except as to the obligations of Bausch & Lomb set forth in this
     Agreement, you, for yourself and your heirs, administrators,
     representatives, and assigns (collectively, the "Releasors")
     hereby release and discharge Bausch & Lomb, and its affiliates,
     agents and employees and their successors and assigns
     (collectively, the "Releasees"), from any and all claims, causes
     of action, liability, damages and/or losses of whatever kind or
     nature, in law or equity, known or unknown, which the Releasors
     ever had, now have, or may have in the future against the
     Releasees from the beginning of time through the date of this
     Agreement, arising directly or indirectly out of your employment
     by Bausch & Lomb or as a result of your separation from
     employment, including, but not limited to, any and all claims
     arising under any state or federal employment discrimination law,
     including but not limited to the Age Discrimination in Employment
     Act, the Older Workers' Benefits Protection Act, Title VII of the
     Civil Rights Act of 1964 and the Americans with Disabilities Act.

16.  You acknowledge that you have been afforded twenty-one (21)
     days to review and consider this Agreement, and that such period
     was a reasonable period of time for you to do so.

17.  You understand that you may revoke this Agreement at any
     time within seven (7) days of the execution hereof, and that the
     Agreement will not become effective or enforceable until the
     expiration of that period.

18.  The compensation and benefits arrangements set forth in this
     Agreement supersede any other agreement between you and Bausch &
     Lomb, and are in lieu of any rights or claims that you may have
     with respect to severance or other benefits, or any other form of
     remuneration from Bausch & Lomb and its affiliates, other than
     benefits under any tax-qualified employee pension benefit plans
     subject to the Employee Retirement Income Security Act of 1974,
     as amended.

19.  Except as required by law or regulation, neither you nor
     Bausch & Lomb will disclose or discuss the terms of this
     Agreement; provided, that you may disclose such terms to your
     financial and legal advisors and your spouse and Bausch & Lomb
     may disclose such terms to selected employees, advisors and
     affiliates on a "need to know" basis, each of whom shall be
     instructed by you and Bausch & Lomb, as the case may be, to
     maintain the terms of this Agreement in strict confidence in
     accordance with the terms hereof.  Bausch & Lomb may also
     disclose the terms of this Agreement as required by applicable
     law or regulations.

20.  As a result of your employment with Bausch & Lomb and as a
     result of your position as an officer of Bausch & Lomb, you were
     obviously privy to sensitive financial and strategic information,
     as well as trade secrets which are the confidential property of
     Bausch & Lomb,  and Company Information (as defined below).  You
     affirm that, as a former officer of Bausch & Lomb, you have a
     fiduciary obligation to maintain Company Information in
     confidence and not to disclose it to others.  You have returned
     or will immediately return to Bausch & Lomb all Company
     Information that is capable of being returned, including client
     lists, files, software, records, computer access codes and
     instruction manuals which you have in your possession, and agree
     not to keep any copies of Company Information.  The term "Company
     Information" means:  (i) confidential information, including
     information received from third parties under confidential
     conditions, and (ii) other technical, marketing, business or
     financial information, or information relating to personnel or
     former personnel of Bausch & Lomb, the use or disclosure of which
     might reasonably be construed to be contrary to the interest of
     Bausch & Lomb; provided, however, that the term "Company
     Information" shall not include any information that is or became
     generally known or available to the public other than as a direct
     result of a breach of this Section by you or any action by you
     prior to the Separation Date which would have been a breach of
     your obligations to Bausch & Lomb in effect at such time.

21.  By this Agreement, you are resigning from all positions and
     offices held by you within Bausch & Lomb and its affiliates. You
     agree that you will, when asked, execute such further instruments
     and documents as are necessary to effect this resignation as to
     all such Bausch & Lomb affiliates.

22.  You agree to make yourself reasonably available to Bausch &
     Lomb to respond to requests by Bausch & Lomb for information
     concerning matters involving facts or events relating to Bausch &
     Lomb or any of its affiliates that may be within your knowledge,
     and to assist Bausch & Lomb and its affiliates as reasonably
     requested with respect to pending and future litigations,
     arbitrations, other dispute resolutions or other similar matters.
     Bausch & Lomb will reimburse you for your reasonable travel
     expenses and costs incurred as a result of your assistance under
     this Section. As you know, the bylaws of Bausch & Lomb provide
     for your indemnification, to the fullest extent authorized or
     permitted by law, in the event there are claims against you
     arising out of your actions while an officer of Bausch & Lomb.
     The bylaws also provide for the advancement of expenses incurred
     in defending any proceeding in advance of its final disposition.
     This agreement is not intended to modify or limit those rights in
     any manner.

23.  You represent and acknowledge that, in executing this
     Agreement, you have not relied upon any representation or
     statement made by Bausch & Lomb or not set forth herein. This
     Agreement may not be amended, modified, terminated, or waived in
     any part, except by a written instrument signed by the parties.

24.  All payments made to you under this Agreement will be
     reduced by, or you will otherwise pay, all income, employment and
     Medicare taxes required to be withheld on such payments.

25.  The parties agree not to challenge nor raise any defense
     against the enforceability of this Agreement or any of its
     provisions in the future.  The invalidity or unenforceability of
     any provision of this Agreement will not affect the validity or
     enforceability of any other provision of this Agreement.

26.  Nothing contained in this Agreement shall be construed in
     any way as an admission by you or Bausch & Lomb of any act,
     practice or policy of discrimination or breach of contract either
     in violation of applicable law or otherwise.
27.  This Agreement shall be governed by and construed in
     accordance with the laws of the State of New York, without regard
     to the principles of conflicts of law thereof, to the extent not
     superseded by applicable federal law. The parties hereto hereby
     agree that any dispute concerning formation, meaning,
     applicability of interpretation of this agreement shall be
     submitted to the jurisdiction of the courts of the State of New
     York (including federal courts in the State of New York), and no
     other state shall have jurisdiction over such matters, and
     further agree to waive all rights to a jury trial with respect to
     any such matters.

28.  You acknowledge and agree that Bausch & Lomb's remedy at law
     for any breach of your obligations under Sections 13, 19 and 20
     of this Agreement would be inadequate and agree and consent that
     temporary and permanent injunctive relief may be granted in any
     proceeding that may be brought to enforce any provision of this
     Section without the necessity of proof of actual damage. With
     respect to any provision of Sections 13, 19 and 20 of this
     Agreement finally determined by a court of competent jurisdiction
     to be unenforceable, you and Bausch & Lomb hereby agree that such
     court shall have jurisdiction to reform this Agreement or any
     provision hereof so that it is enforceable to the maximum extent
     permitted by law, and you and Bausch & Lomb agree to abide by
     such court's determination.

If the terms and conditions are agreeable to you, please indicate
your acceptance of the above in the space provided below and
return the enclosed copy to me.

Sincerely,

/s/ William M. Carpenter
