Organized by BOAF-EASO and hosted at Scott Eye Care, Oswego - IL -USA

This seminar given by Stefan Collier will be a journey into the basic underlying components of Local-Focal Syntonic Optometry.

Local-Focal Syntonic Optometry is a method applying specific light wavelengths to extrinsic muscle points, and other vision points on the body to bring an energetic balance to improve visual function. It has been tested on a variety of vision problems, with Syntonic Optometric testing before and after to determine the immediate response.
