§ 643. Consideration of blindness during adoption proceedings. 1. The
court may not deny or decide a petition for adoption solely on the basis
that the petitioner is blind. The blindness of the petitioner shall be
considered relevant only to the extent that the court finds, based on
evidence in the record, that the blindness affects the best interests of
the child whose adoption is the subject of the petition.

2. As used in this section, "blind" or "blindness" means:

a. vision that is 20/200 or less in the best corrected eye; or

b. vision that subtends an angle of not greater than twenty degrees in
the best corrected eye.
