Worth-4 Dot Test

T or F: The Worth 4-Dot Test is done at far and near.

True

T or F: In Worth 4-Dot test, if the patient sees only two and there are two red targets, that means the patient's OD is suppressed because they only saw red.

False

T or F: In Worth 4-Dot test, if the patient sees only two and there are two green targets, that means the patient's OD is suppressed because they only saw green.
