The VisionBuilder program is designed to be an adjunct tool used as part of a comprehensive optometric vision therapy program.
Your optometrist will give you guidance as to which parts of the program are best suited to your specific needs and as such should be
the one to tell you what levels and settings would be best for you and the continued development of your visual abilities.
You may use VisionBuilder as a stand-alone tool to improve your visual abilities, but the use of any computer program will never replace the need for a comprehensive vision therapy program.
If you do not have a license key this will be provided by your optometrist.
