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.
