Which extra point is known to benefit the eyes?

The extra point that is known to benefit the eyes is located along the inferior border of the eye orbit. This point is particularly relevant in Traditional Chinese Medicine (TCM) as it is associated with eye health and vision enhancement. The location of this point makes it effective for addressing various eye conditions, such as dryness, redness, and fatigue, as well as other visual disturbances.

In TCM, points located around the face and head often correlate with the organs they represent and can influence their functions. This particular extra point can help to alleviate symptoms related to eye strain or other ocular issues due to its proximity to the eyes and its specific influence on local energy flow.

The other locations mentioned, such as those at the temple area, naso-labial groove, or back of the neck, may have their own therapeutic uses but are not primarily indicated for eye health. Therefore, the correct identification of the eye-related extra point underscores its significance in managing ocular health within the framework of TCM practices.
