The Berens 3 Character Test is designed for patients who are unable to respond to the Worth 4-Dot Test, such as children who cannot name colors and individuals with low color perception.

The 3 characters are a red girl, a green elephant, and a white ball. All are reproduced on a special insert that goes over the flashlight lens.

The test set consists of a high-quality, three-cell flashlight with a pair of universal spectacles together and complete instructions. 3D-cell batteries included.
