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 language in Virtual Refractor can now be changed to French, Spanish, Portuguese, Chinese and Russian.

Brien Holden Vision Institute
Bondi Labs is a startup developer of both proprietary and third party 3D virtual simulation training and assessment software, which addresses specific challenges facing governments, industries, non-profits, and the education sector. Bondi Labs has strategic R&D partnerships with the Queensland University of Technology (QUT) and the University of the Sunshine Coast (USC), with software development labs at both.
Why have we developed Virtual Refractor?At the Institute we believe:
- Training and innovation is key to improving eye care to everyone...everywhere
- Students and educators across the world should have access to the latest technology for engagement, self-directed learning and assessment
- To increase access, the Virtual Refractor is now available at no charge
How has Virtual Refractor been developed?
- We have drawn on our experience in teaching refraction all over the world to understand the training needs of optometrists and educators.
- We have in-house expertise to develop complex algorithms as well as clinicians to develop and test the software
- We have collaborated with leading serious 3D educational gaming experts to design the tool
What are the features and benefits?Virtual Refractor provides a realistic experience that allows you to learn refraction faster, and in your own time.
You can use Virtual Refractor anytime, anywhere with an internet connection. Users receive immediate feedback on their performance which can lead to increased accuracy, comfort and speed in the refraction process.
The current version of Virtual Refractor has received positive feedback from Academics worldwide. Associate Professor Barbara Junghans, School of Optometry and Vision Science, University of New South Wales, Sydney, said, “We have reduced a significant number of hours out of our practical hands-on sessions where we teach the process of refraction by setting at home Virtual Refractor assignments.”
Can institutions use the Virtual Refractor?
The institution version of the software includes the ability for teachers to set assessment and practice tasks for their students, and monitor their performance on these tasks in detail, either remotely or in-person.
If you are an institution and would like to access a trial please contact the Academy
How do I access Virtual Refractor?A free Brien Holden Vision Institute Academy account is required to access the full version of the Virtual Refractor.
The account also provides access to other free optometric educational materials, most at no charge.
The full version of the Virtual Refractor includes ongoing access to:
- Assessment mode, for an immediate mark out of 100 for each refraction
- All patient types
- Administrative console with logs of each refraction completed
- Multi-language capability (French, Spanish, Portuguese, Chinese, Russian)
- User guide
If you are an institution and would like to access a trial which includes the advanced classroom features listed above, please contact the Academy.
What software is Virtual Refractor built with?Virtual Refractor is built on Unity - a flexible and powerful development platform for creating 3D and 2D games and interactive experiences.
You will be required to download the Unity Web Player plug-in on opening on Virtual Refractor for the first time.
Does Virtual Refractor work in all web browsers?Virtual Refractor requires the Unity Web Player to function. Browsers which support the Unity player include Firefox, Internet Explorer, Safari and Opera. Chrome is not currently supporting the Unity player.
Does it work with Mac?Yes, Virtual Refractor is fully functional on the Safari browser.
Is a tablet version available?The buttons and functions of Virtual Refractor are not currently optimised for operation on a tablet. However, development is on-going, so future versions of Virtual Refractor may be tablet-ready.
What future functionality will Virtual Refractor have?Development for Virtual Refractor is ongoing. In 2016, we introduced multi-language capability (giving access in (French, Spanish, Portuguese, Chinese and Russian), and a timeline of steps completed by the student for each refraction.
In the future, we are looking to implement “key milestone” functionality. This means the student and teacher will receive feedback on whether the “milestones” below are completed during a refraction.
This way both teachers and student will know not just if their result is correct, but if they are using best practices to arrive at their results. Teachers can look at class trends per student or milestone and take appropriate corrective action if there are particular problematic points. These milestones will also be included in the assessment system.
The long term view is to add more clinical functionality to the software, including more binocular vision tests, ocular health tests, and contact lenses and dispensing. The Institute welcomes feedback and suggestions for future functionality of the software.
