This report shows the relationship among legibility, individual visual ability and age by introducing Relative Acuity (RA), that is the ratio of Maximum Visual Acuity (MVA) to visual acuity necessary for distinguishing characters. 86 Subjects (Young and the Aged) evaluate the legibility of documents. Experimental variables are background luminance, luminance contrast, character size, MVA and age. If MVA is equal, the relationship between factors of visibility and legibility is equal for each age group. The legibility under the same RA can be treated equally regardless the combination of MVA and character size, if the ratio of character size is from 2/5 to 5/2. Background luminance and luminance contrast does not have effects on RA under the condition of this examination. Also the difference in aees does not have effects on RA, except for the high visibility conditions under which the Aged evaluates "easy to read".
