Here's how it works:

1. The school assigns students to a location, class or teacher where training will occur.
   
   
2. A teacher or aide (trained by Gemstone) introduces the student to the training program and the tools needed (colored glasses and flipper lenses). The instructor guides the student through the first few sessions.
   
   
3. Daily sessions on the computer continue for 30 - 60 sessions, each lasting about 20 minutes a day. After each session, the student receives immediate feedback from the Gemstone server, which collects and analyzes student progress online.
   
   
4. After 30 sessions of therapy, Gemstone doctors screen each student again for Visual Inefficiency Syndrome (VIS). This data is compared to the starting data to determine if the student is ready to be released from the program. If not, the student is referred for additional DVT^© at school.
   
   
5. If further training is needed, the student is scheduled for an additional 30 sessions. At the end of six weeks, the student is evaluated again for VIS. If the student still hasn't achieved release level -- or an acceptable reduction of visual symptoms -- they are referred to a vision specialist in the community for further professional attention.
