Sankan (LI3) is a very convenient point and is good to use for eye problems as well. But the technique to use the point for the eyes is a little different from the one for the ears. I don't insert needle because I use a round-tip needle, but the depth of pressing the point should be shallower. This point is often used when a patient can't see clearly. Yesterday I used this point for a patient who had watery eyes. She reported that she had felt that tears had been sucked through the tubes attached to the eyes while I was touching the point with a round-tip needle. That's interesting.
