Client Qualifications

Our clients and patients are people who reside in Pennsylvania’s Lehigh, Northampton, and Monroe counties and live with what is identified clinically as “low vision.”

While there is no uniform definition of “low vision” throughout the United States, we rely primarily on criteria established by the Pennsylvania Bureau for Blindness and Visual Services (BBVS), which also are used by the American Foundation for the Blind (AFB).



Under these criteria, a person is considered to be of “low vision” if he or she meets at least one of the following standards:

  • He or she has a visual acuity of 20/70 or less in their strongest eye with best correction.
  • He or she has a visual field of 20 degrees or smaller in their strongest eye with best correction.
  • He or she has a visual function level that is equivalent of an acuity of 20/70 or less in their strongest eye with best correction.

A person must provide a physician’s documentation of his or her condition(s) from the previous 12 months to be enrolled as a client. We ask potential clients and patients for permission to obtain records from their doctors.
