Get started!
You need two things to solve aniseikonia for your patients:
- A PC computer running Windows XP or better and connected to the Internet with the SHAW lens design software.
- Risley, loose or bar prisms to measure vergence facility.
The software is FREE. There is no obligation to order. You must be a registered optometrist. Please have your optometry license number available.
Once your account has been activated, you’ll be prescribing the SHAW lens with ease. The SHAW lens design software only takes a few seconds to download, and is easy to learn and use.
