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.
