- This test measures your ability to see a pattern based on its color.
- By testing with different colors we are able to understand which colors you may have difficulty seeing.
- When a person has color blindness, they are able to see some colors better than others.
- Provide an easily administered check of stereoscopic depth perception at any age level.
- Its purpose is to measure how minutely the two eyes can discern differences in the distances of objects from the observer.
