Learn refraction faster, anywhere and anytime

Virtual Refractor simulates a distance and near subjective optometric refraction, using a refractor head on virtual patients. There are numerous patients, prescriptions and profiles, and the patients respond to test questions and charts based on user input.

To develop the Virtual Refractor, we have drawn on our experience in teaching refraction all over the world to understand the training needs of optometrists and educators, and have collaborated with leading 3D educational gaming experts to design the tool.

Virtual Refractor is an outstanding introduction to refraction for the new student, and also provides a useful refraction refresher for more experienced clinicians.

The Virtual Refractor was originally created in 1998 by Dr Jack Alexander who generously donated the Virtual Refractor to the Brien Holden group for use in improving refractive care, particularly in places of high need and low resource.

The Brien Holden Vision Institute and Brien Holden Foundation further developed the Virtual Refractor into an award-winning simulator, proven useful in a variety of settings, from world-renowned optometry schools to developing training centres for ophthalmic personnel.
