# Look at the near fixation bead. Keep this bead single as you look directly at it. If the near bead is double this indicates an eye teaming problem. If this occurs move the near bead closer or further away until you see it as a single bead. The near bead should be moved closer and closer as the task becomes easier. Eventually the near bead should be only one inch from the bridge of your nose. # As you look at the near fixation bead you should see two<unk> s, each of which appears to come from your eyes. If your fixation on the bead is accurate, the two<unk> s should appear to meet exactly at the bead forming an "X". As the bead is moved to one inch from your nose, the two<unk> s should appear to meet exactly at the bead forming a "V". # Shift fixation to the middle bead and then to the far bead and repeat. If your fixation of the far bead is accurate, the two<unk> s should appear to meet exactly at the bead forming a "V". # Change the location of the fixation beads and again repeat. # Try to be aware of other objects in your field of view as you practice. # Slowly turn your head from side to side through an angle of about 45 degrees maintaining your vision of the two<unk> s at all times. (if you turn too far one<unk>  will disappear)
