What Is Problematic About the Legal Criteria Used to Determine

What is problematic about the legal criteria used to determine degrees of visual impairment,especially with regard to the development of children?

A) No consistent federal guidelines for classifying visual impairment have been adopted.
B) Determining impairment is based on the judgment of a family physician,and that judgment may be flawed due to lack of training or special considerations.
C) Most insurance companies don't reimburse for corrective lenses;therefore,children and their parents are reluctant to admit to visual difficulties.
D) The criteria pertain solely to distance vision,whereas children with visual difficulties usually engage in close-up visual tasks in the classroom.
