Eye test
I have just went for a full-body checkup. During one of my eye tests, one of the nurse used a thin long black instrument(about an arm's length) with words printed on a small rectangular box. Then she put the instrument onto my upper part of the nose where the center of both of my eyes are. She then asked me to read the words from a certain distance, read another time at a different length. She can slide the rectangular box up and down. Then she asked me to stop her when the words get blurred when she slide all the way to the front of my eyes. May I know what is the name of this device? and what it is test for?
