If a depress person shows symptom of hallucination, and one of the experience point that we use is called Urine Bladder 1. And this point is located at the corner, in the corner of the eyes. So this inner corner called canthus is one 1.5 inch above the inner canthus. So this is the Bladder1 point and we use this point to treat many symptoms of the eye. For example, redness of the eye, or too much tears, or itchy eyes, or nearsighted, blindness at night. And this point we have to be very careful to insert needles. So we use the left hand to push the eyeball to the lateral side, and then, we use the right hand to insert needles perpendicularly, .3 and just close to the orbit bone. And when you take out needles, you have to press that hard to avoid bruises or bleeding.
