N2  - In the detection of eye malingering we have adopted the old and simple method of inserting in the trial frame a strong convex lens on one side with a plano lens on the other, without the patient's knowledge of the relation of the lenses, and with rarely a suspicion that he is being subjected to a test for malingering. The strong convex lens, which excludes vision at a distance of 20 feet, is placed over the patient's good eye, with a plano lens over his supposedly injured or amblyopic eye. Then, with both eyes open, the patient is asked to read the letters on the test chart. Any resulting vision is very evidently the vision which the patient obtains with the supposedly defective eye. This is a very simple test, and demonstrates to what extent the patient sees with the eye in question.There are numerous devices for the detection
