Acuity Measurements--Do They Indicate How Well a Partially Sighted Person Functions or Could Function,
RAND CORP SANTA MONICA CALIF
Pagination or Media Count:
Probably the most tragic thing that has been done with distant visual acuity measurements to date is their use as the major criterion by which to judge whether a person is blind or sighted.
