Active Prisms

Active prisms are conceived as a means to enter the proprioceptive system, using the eyes to reach the brain. These prisms are not conceived to correct eye deviations as the usual prisms. Their purpose is to influence the brain proprioceptive centers and modify the proprioceptive output. They are low-powered and prescribed according to the relaxation axis of a specific eye muscle. Active prisms are not prescribed by "trial and error" techniques but according to specific procedures.
