Final answer:
In an Anomaloscope test, the test field is typically displayed first. The patient then tries to match this color using a mixture field, aiming to demonstrate normal color perception.
Step-by-step explanation:
An Anomaloscope is a device used primarily in ophthalmology to test color vision. In using an Anomaloscope, the test field is generally displayed first. This field typically shows a comparison color that is a mix of red and green. The patient then tries to match this color by adjusting the brightness and ratio of a mixture field, usually yellow. The goal for the patient is to correctly match the comparison color, thus demonstrating normal color perception.
When using an Anomaloscope, the test field is displayed first. The patient is trying to achieve color vision accuracy and differentiate between different shades of color. The test field usually contains a mixture of red and green lights, while the mixture field contains a specific combination of red and green lights that the patient needs to match.
