Lea Symbols Visual Acuity Test System developed by Lea Hyvarinen, M.D. The Lea Visual Acuity Test System is the only complete set of visual acuity tests for near and far distance vision for all patient groups 18 months and over. The tests are based on four symbols which blur equally at the threshold. The tests are designed to create a play situation where the child never experiences failure.
When no longer correctly recognized, the symbols transform into circles appropriately called "rings" or "balls" by the child. The child can still perceive that he/she is answering "correctly", while the examiner can easily detect the acuity threshold. The symbols are easy to name, sign or point to on the Key Card or Flash Cards.
| Technical | Proportionally-spaced lines; line sizes range from 20/125 to 20/8 (6/38 to 6/2.4) equivalent. |
