| Abstract |
The present study was designed to investigate the legibility of broken lines for persons with partial sight. The subjects were 10 persons with simulated partial sight, and 4 persons with partial sight. The simulation was obtained using filters and convex lenses. The 30 kind of broken lines was evaluated by the original test that the subjects were read directions of the broken lines in distinction from solid lines. The thickness of lines varied from 0.1mm. to 0.7mm. in 4 steps.
The results were as follows: (1) For all subjects, the conditions of broken lines that the spaces width were 0.5mm and 1.0mm were inadequate for partial sight. (2) The broken lines with wide space were inadequate for partial sight. (3) For subjects with partial sight, adequate spaces width of broken lines were equally and over to Landolt's rings gap that were measured the near visual acuity. |
