Currently in the world arena of most police, military, corrections, and security training, students learning eye gouges have to practice the technique/tactic on each other. Aside from the obvious potential injury problems, this does not accurately reflect the required penetration of passing the frontal plane of the eye as trainees have to use a “touch drill only” on the closed eye of their partner. Sometimes students place their thumbs/fingers on the forehead of the “suspect/enemy/attacker” to prevent possible injury. The problem with that technique is that it sets incorrect blueprints and does not allow the student to psychologically or physically engage and attack the proper area therefore creating bad landmarking habits.
Safety glasses are sometimes worn which “allow” the student a chance to “touch” the “eyes”, but unfortunately this is counterintuitive (and potentially dangerous should the plastic lens or frame fracture). Also in the real world, if the suspect was wearing glasses, the trainee should learn to bypass the glasses (by angles/rips) and follow through with the proper eye gouge attack.
