For exams in which the child is familiar with the LEA Symbols, the new LEA Symbols Suppression test attachment provides the same Worth 4 Dot capability using LEA Symbols as the targets.
The suppression test attachment fits on your Welch Allyn or Keeler transilluminator and supports Worth 4 Dot testing using red/green goggles. Compared to conventional flashlight versions, the LEA Symbols Suppression Test attachment does not require cumbersome flashlight units or D batteries.
