  at the clinic and parents/guardians.  The clinic offers care to children with special needs and is an active participant with
  Special Olympics Lions Clubs International Opening Eyes Programs.

Chicago, IL : pop. 2.705 Million in 2016

Chicago is located in the Midwest along the Great Lakes shoreline.  It is the third largest city and metropolitan area in
the United States with a city population approaching 3 million and a metro population approaching 10 million.  Chicago is
a huge vibrant city and metropolitan area that sprawls over 10,887km.  It is well known for house music and
electronic dance music, blues, jazz, comedy, shopping, dining, sports, architecture, highly-regarded colleges and
universities, and premier cultural attractions.

As the hub of the Midwest, Chicago is easy to find with its picturesque skyline calling across the waters of the freshwater
Lake Michigan, an impressive sight that soon reveals world-class museums, miles of sandy beaches, huge parks,
public art, and perhaps the finest looking downtown in the world.

With a wealth of iconic sights and neighborhoods to explore, there is enough to fill a visit of months without ever
seeing the end.  Prepare to cover a lot of ground; the meaning of Chicago is only found in movement, through
its subways and historic elevated rail, and eyes raised to the sky.  ""




  • The IEI at Princeton is the largest school based vision clinic in the country.  We are housed in
    a previously closed Chicago Public School.  We have one school bus every day bring 20 - 45
    children to our clinic.  We also have walk-in hours between 8:30 - 9:30 am and offer appointments
    all day.  We provide high quality comprehensive eye care to our patients who typically have
    difficulty accessing service due to limited insurance or no insurance.  We utilize 3 AmeriCorp
    members to help ensure the flow of the clinic serves the patients and optometry students as well.
    In addition they work to manage follow ups when needed.  The clinic provides OCT, photos,
    corenal topography, vision therapy, visual processing testing and medically necessary contact lenses. 
    We are a safety net for the neighborhood we are located in but we have patients coming from
    more than 20 miles because of the lack of other resources.  Our uninsured rate has substantially
    increased in the past year so we are aware that the need for our services continues to grow.  We
    want the extern to learn the importance of eye care in a public setting, to learn what the best way
    to address the visual needs of children and the excitement of providing high quality eyecare to
    children from birth to high school graduation.  

  • Reference library available for student use
        Everyone at IEI at Princeton has access to the service provided at the IEI main eye clinic and library
        resources at the Illinois College of Optometry.  We currently have all specialties at our main campus and work
        with them when our patients have the need to be referred on campus.  We have three AmeriCorp
       members who spend a year of service with us and act as case managers for our patients.
  • Internet access available
    The clinic is located in a previously closed Chicago Public School.  Four classrooms have been converted into
    13 fully equipped lanes.  One preceptor is located in each of the four rooms.  In addition, we have pre-testing
    and a vision therapy room.
