However, Cassey remembered when he did it in his clinical procedures class, so he takes a deep breath and calls the patient, Mr. Saleto. After identifying the patient and welcoming him in the room, Cassey explains the procedure to Mr. Saleto. What should be the distance between Mr. Saleto and the Snellen chart? What instructions can Casey give to Mr. Saleto if he uses glasses? By using the Snellen chart, is Cassey testing distance or near visual acuity? What does it mean if the result of the test is 20/60?
