Good-Lite LEA Symbols Single Symbol Book

Image for illustration purposes only, actual product
may vary. See item title & description for details.
The LEA Symbols Single Symbol Book was created for testing children and adults who have difficulties in perception of symbols in lines. The visual acuity values measured with single symbols are often several lines better than the line acuity values in people with impaired vision and therefore overestimate the quality of visual functioning.

  • Single optotype line sizes from 20/200 to 20/8 (6/60 to 6/2.4) equivalent, 0.10 to 2.50.
  • 13 offset pages for easy flipping.
  • Testing distance: 10 feet.
